00:00:17,12 --> 00:00:19,72
good book

3
00:00:31,29 --> 00:00:35,87
from the beginning of time each passing
age has left behind some vital knowledge

4
00:00:35,87 --> 00:00:40,62
that has helped make this world of ours a
better place in which to live knowledge

5
00:00:40,63 --> 00:00:45,81
that is made possible the countless
conveniences we all enjoy today we look upon

6
00:00:45,81 --> 00:00:48,07
them as our natural right
to take them for granted

7
00:00:49,00 --> 00:00:52,34
and once having used them give
no thought to days gone by

8
00:00:53,16 --> 00:00:56,84
when people did without even the
simplest of all these hard won benefits.

9
00:00:57,09 --> 00:01:03,03
Yet nothing in today's wonderful world
has come to a party from the song every

00:02:21,83 --> 00:02:26,96
The world looks for better things for
better living through chemistry the science

00:02:26,96 --> 00:02:31,45
that has played a major part in the perfection
of practically everything we use the

45
00:03:39,86 --> 00:03:43,99
of fashion within the space
of a few short years. Today.

00:03:44,15 --> 00:03:48,37
Re on fabric to enhance luxurious
creations from fashion headquarters here

47
00:03:48,37 --> 00:03:48,76
and abroad.

48
00:03:51,92 --> 00:03:57,56
Today in no other text the fiber makes so
many types of cloth Israel sheer fabrics

00:03:57,56 --> 00:03:59,70
every Babbitts rough fabric.

50
00:04:00,00 --> 00:04:05,79
Fabrics that are bright fabrics that are
dull fabrics that was perfect fabrics

wall linen or cotton.

54
00:04:15,75 --> 00:04:20,89
All these properties depend on how we each
fabric is made its construction dying

55
00:04:20,89 --> 00:04:26,01
and other finishing operations as well
as the quality of the our new the fact

56
00:04:26,01 --> 00:04:29,36
that Ray on yarn successfully meets
the requirements of textile makers

57
00:04:29,36 --> 00:04:32,22
and uses one great reason
for its rapid growth

58
00:04:32,22 --> 00:04:37,77
and wide acceptance within the space
of comparatively few years hundreds of

59
00:04:37,77 --> 00:04:42,26
millions of pounds of yarn are required
each year to meet the ever growing demand

00:04:57,95 --> 00:05:03,12
and fabric right in practically every
household in the civilized world.

64
00:05:03,14 --> 00:05:06,17
A product of test tube and
retaught it is obvious

65
00:05:06,17 --> 00:05:11,84
that better a on means better chemistry
right on by your band enjoys a heritage of

66
00:05:11,84 --> 00:05:17,34
leadership unsurpassed in the chemical
industry right on by Dupont sets the pace of

67
00:05:17,34 --> 00:05:23,68
textbook progress with the promise of still
finer still better things because many

68
00:05:23,68 --> 00:05:26,40
of us may go right on as a
type of cloth or fabric

69
00:05:26,40 --> 00:05:29,74
that comes in a wide variety of
textures weights and finishes.

70
00:05:29,81 --> 00:05:34,09
Actually it is a basic material
from which such fabrics are made.

71
00:05:34,97 --> 00:05:36,73
Just like war linen cotton

72
00:05:36,73 --> 00:05:42,80
or silk Ron is a true textile fiber each
individual hair like fiber is called a

73
00:05:42,80 --> 00:05:43,99
filament.

74
00:05:44,00 --> 00:05:45,58
But a number of elements are twisted

75
00:05:45,58 --> 00:05:49,70
or laid together we have a yarn
which may be woven knitted

76
00:05:49,70 --> 00:05:55,88
or formed in other ways into fabrics like
all other textile fibers Braylon has its

77
00:05:55,88 --> 00:05:59,40
own individual qualities and
properties. Since it is man made.

78
00:06:00,00 --> 00:06:01,42
Under scientifically
controlled conditions.

79
00:06:01,94 --> 00:06:04,70
It is the most uniform
of all textile fibers

80
00:06:04,70 --> 00:06:10,50
and can be varied to great advantage in its
construction for example on celebrants

81
00:06:10,50 --> 00:06:13,26
are continuous can be
produced in great lengths

82
00:06:13,99 --> 00:06:18,26
and may be made finer than those of the
silkworms are thicker than horsehair of

83
00:06:18,26 --> 00:06:22,91
course will you know addition to long
continuous filaments right on is also

84
00:06:22,91 --> 00:06:28,04
produced in short uniform lengths
usually from about one to six inches.

85
00:06:28,06 --> 00:06:32,78
This is known as re on staple fiber you
plant was the first company to make rail

86
00:06:32,78 --> 00:06:36,83
and staple fiber on a commercial
scale in the United States.

87
00:06:36,85 --> 00:06:40,48
The use of re on Staples has increased
tremendously in the past few years.

88
00:06:40,96 --> 00:06:42,53
Largely because of the new

89
00:06:42,53 --> 00:06:46,08
and unusual fabric effect made
possible by a sharp fiber.

90
00:06:47,21 --> 00:06:51,72
Textile mills Penry on a staple fiber an
outstanding example of the versatility of

91
00:06:51,72 --> 00:06:57,47
the re on manufacturing process into yarns
known as spun rail fabrics made of spun

92
00:06:57,47 --> 00:07:01,77
Rayyan have a distinctive woolly
feel pleasing softness to the touch.

93
00:07:02,33 --> 00:07:05,05
Sometimes spun Rayyan yarns are used alone

94
00:07:05,05 --> 00:07:09,77
and sometimes they are blended with
other fibers such as cotton wool

95
00:07:09,77 --> 00:07:13,82
or flax Rayyan yarns may contain
any number of elements.

96
00:07:14,13 --> 00:07:17,63
Usually the ranges from thirteen
to two hundred seventy.

97
00:07:18,27 --> 00:07:23,97
For example here are five specimens
of re on yarn all the same size. Yet.

98
00:07:24,02 --> 00:07:29,31
Notice the wide variation the number of
filaments contained in each sample number

99
00:07:29,31 --> 00:07:31,47
one is composed of ten fellow months.

100
00:07:31,78 --> 00:07:38,45
Number two twenty filaments number
three for a fella months number for

101
00:07:38,45 --> 00:07:44,37
sixty fellow months and number
five one hundred filaments.

102
00:07:44,39 --> 00:07:48,28
Ray on the arms provide fabrics and a
wider range of weights and textures.

103
00:07:48,61 --> 00:07:53,60
Than those of any other textile fiber because
of this pose control of uniformity in

104
00:07:53,60 --> 00:07:55,80
the size and number of filaments desired.

105
00:07:56,78 --> 00:07:59,95
Another great advantages
that light ray on the.

106
00:08:00,00 --> 00:08:06,09
Manes white it does not yellow with a
positive control of luster is also possible

107
00:08:06,09 --> 00:08:10,06
with a rail. There are
brilliant yarns more lustrous

108
00:08:10,06 --> 00:08:16,34
and silk semi less press yarns with
varying degrees of brilliance and yarns

109
00:08:16,34 --> 00:08:21,30
that are completely dull in the parents
these properties are absolutely paramount

110
00:08:21,30 --> 00:08:26,31
in rail because they are chemically ingrained
before each tiny film of this fall

111
00:08:27,49 --> 00:08:31,20
with your pant Raynaud's versatility
reaches new and unusual heights.

112
00:08:31,59 --> 00:08:36,25
When the need arose for a on yarn with
special characteristics not then possessed

113
00:08:36,25 --> 00:08:42,88
by any other A on your part developed a
yarn to meet the need cardio are the core

114
00:08:42,88 --> 00:08:47,35
jewels in making automobile tires demand
exceptionally high strength as well as

115
00:08:47,35 --> 00:08:50,76
resistance to keep and flexing
card your a re on your

116
00:08:50,76 --> 00:08:52,65
and fill these requirements so well

117
00:08:52,65 --> 00:08:55,95
that large quantities are used
annually both in truck tires

118
00:08:55,95 --> 00:08:59,51
and tires for fashion
your car and its strength

119
00:08:59,51 --> 00:09:03,40
and uniformity have also brought about
its use in the sales of racing yachts

120
00:09:03,40 --> 00:09:07,02
and for other purposes in which
on usual properties are required.

121
00:09:09,57 --> 00:09:13,86
In the manufacture of array on there are
three different methods generally you the

122
00:09:13,87 --> 00:09:18,66
best goes process the cellulose as a trade
process and the Cupra monium process.

123
00:09:19,16 --> 00:09:21,04
It is important to bear in mind

124
00:09:21,04 --> 00:09:25,21
that yarns are made by all
these processes are rail.

125
00:09:25,22 --> 00:09:26,94
While each has its own
different characteristics.

126
00:09:27,44 --> 00:09:33,05
Generally speaking these concern the maker
of fabrics far more than the user the

127
00:09:33,06 --> 00:09:35,29
best course and cellulose
acetate processes.

128
00:09:35,45 --> 00:09:40,21
Both employed by Dupont account for
approximately ninety five percent of all rain

129
00:09:40,21 --> 00:09:44,58
on produced in the United States some
fabrics are made entirely of discourse

130
00:09:44,58 --> 00:09:46,27
process rail others

131
00:09:46,27 --> 00:09:51,84
and tireless acetate rail the two types
of yarn are also combined to make many

132
00:09:51,84 --> 00:09:54,90
distinctive fabrics with pleasing
color effects and design.

133
00:09:56,10 --> 00:09:59,91
For example this piece of
undying white cloth is made in.

134
00:10:00,00 --> 00:10:01,55
Tire Levesque cause process Rayyan.

135
00:10:02,02 --> 00:10:05,59
And here is a diet particularly
suited to the fabric on the table

136
00:10:06,31 --> 00:10:09,43
when properly dyed the
cloth colors completely

137
00:10:09,43 --> 00:10:15,71
and evenly a solid color this piece of
undying white cloth is made entirely of

138
00:10:15,71 --> 00:10:20,78
acetate rail and when properly treated
with the dye shown in this flask. It too.

139
00:10:20,79 --> 00:10:23,44
Takes on a beautiful even solid tint.

140
00:10:23,75 --> 00:10:28,83
As the dyed sample reveals the piece of
iron died a white cloth in the center is

141
00:10:28,83 --> 00:10:32,01
made of both yarns when
the two days are mixed

142
00:10:32,01 --> 00:10:34,81
and the cloth is dipped into
the combination dye a bath

143
00:10:34,81 --> 00:10:39,51
and interesting to color pattern is the
result of the First Cause process yarn

144
00:10:39,51 --> 00:10:41,66
takes on color from the diaphragm
which it has an affinity

145
00:10:42,56 --> 00:10:48,75
and the acetate yarn is affected by its
particular dye this principle called across

146
00:10:48,75 --> 00:10:50,42
dyeing unable to rain

147
00:10:50,42 --> 00:10:55,22
and to provide countless contrasting color
affects both an already on combination

148
00:10:55,22 --> 00:10:58,64
fabrics and in fabrics made over
a on an other texture favorites.

149
00:10:59,08 --> 00:11:03,48
From all this we begin to realize that
both yarns are extremely valuable

150
00:11:03,48 --> 00:11:07,86
and distinctive additions to the limited
group of other important fabric sources

151
00:11:07,86 --> 00:11:14,06
linen cotton silk and war. Both
are a are man made textile fiber.

152
00:11:14,31 --> 00:11:19,32
That is opened up new fields
of textile beauty and utility.

153
00:11:20,56 --> 00:11:24,97
As with other sources of textile yarns
nature's supply is a principle raw material

154
00:11:24,97 --> 00:11:30,39
from which rain on is made cellulose cellulose
is the main constituent in all plant

155
00:11:30,39 --> 00:11:34,60
life. If we examine a tiny cross-section
of vegetable matter under the microscope.

156
00:11:35,31 --> 00:11:41,43
We see a series of minute chambers or cells
joined together by a binding substance.

157
00:11:41,45 --> 00:11:45,92
The walls of these cells are made of cellulose
which must be a pain in a very pure

158
00:11:45,92 --> 00:11:49,18
state before it is
suitable for making rail.

159
00:11:49,20 --> 00:11:53,11
That means all other materials have to
be carefully and thoroughly removed.

160
00:11:53,73 --> 00:11:58,68
In finely equipped laboratories each
lot of purified cellulose is carefully

161
00:11:58,68 --> 00:11:59,81
analyzed by a series.

162
00:12:00,00 --> 00:12:04,49
Thorough chemical tests the highest
standards are rigidly maintained.

163
00:12:04,75 --> 00:12:05,24
And none

164
00:12:05,24 --> 00:12:10,47
but the best cellulose gets by these
exacting technicians the extreme degree of

165
00:12:10,47 --> 00:12:10,77
skill

166
00:12:10,77 --> 00:12:16,63
and care employed here ensures fine cellulose
the only kind of cellulose from which

167
00:12:16,63 --> 00:12:17,86
finer Ayaan can be made.

168
00:12:19,75 --> 00:12:21,99
The methods of making are a
on by the viscous process

169
00:12:21,99 --> 00:12:25,77
and the cellulose as a date
process differ widely.

170
00:12:25,79 --> 00:12:30,48
But in both cases the manufacturing can
be roughly divided into three major steps

171
00:12:31,32 --> 00:12:33,93
first cellulose is changed
into liquid form.

172
00:12:34,31 --> 00:12:38,66
Second the liquid is drawn
out into a very fine streams

173
00:12:38,66 --> 00:12:42,88
and third these liquid streams
are changed into solids felons

174
00:12:42,88 --> 00:12:44,55
and combined into you are.

175
00:12:45,86 --> 00:12:48,57
To get a rough idea of how these
changes are accomplished.

176
00:12:48,75 --> 00:12:52,28
Let us quickly run through the steps
involved in the manufacture of this cause

177
00:12:52,28 --> 00:12:57,30
process re-arm We began by softening the
cellulose in the solution of sodium

178
00:12:57,30 --> 00:12:59,20
hydroxide.

179
00:12:59,22 --> 00:13:03,59
After a proper amount of time the cellulose
is squeezed to remove excess liquid.

180
00:13:03,76 --> 00:13:10,46
The soft moist part of the remains is known
as alkali cellulose next the material

181
00:13:10,46 --> 00:13:14,75
is thoroughly torn up into crumbs which
must be aged for many hours during which

182
00:13:14,75 --> 00:13:16,22
chemical changes take place.

183
00:13:17,55 --> 00:13:21,82
Then the addition of a liquid called
carbon by sulfide causes another chemical

184
00:13:21,82 --> 00:13:28,06
change the batch shrinks in volume to
about half its original size its color

185
00:13:28,06 --> 00:13:33,20
gradually changes to a brilliant orange
which gives this step its name sensation.

186
00:13:34,51 --> 00:13:38,43
When the orange colored crumbs are dissolved
in water containing a small amount of

187
00:13:38,43 --> 00:13:43,43
sodium hydroxide the result is a syrup a
liquid much like honey and appearance

188
00:13:43,43 --> 00:13:49,75
and flow called fiscal solution.
This is the spending solution.

189
00:13:49,77 --> 00:13:52,86
So far we have seen nothing that
looks like a textile fiber.

190
00:13:53,08 --> 00:13:57,11
But when we drop a slender stream of the
spinning solution into a hardening bath.

191
00:13:57,26 --> 00:13:59,88
Notice what happens it congeals.

192
00:14:00,00 --> 00:14:05,70
Immediately changing from a liquid into a
flexible cellulose threadlike material a

193
00:14:05,70 --> 00:14:10,58
crude form of this cause process railed
in producing rain on by the cellulose

194
00:14:10,58 --> 00:14:14,58
acetate process the spinning solution
is made in an entirely different way.

195
00:14:15,51 --> 00:14:19,58
When the solution is exposed to the
action of warm air the acetone evaporates

196
00:14:19,58 --> 00:14:25,15
leaving a solidified substance a crude
form of cellulose acetate ray on which as

197
00:14:25,15 --> 00:14:27,85
its name implies is a chemical compound.

198
00:14:29,18 --> 00:14:32,69
While these rough demonstrations reveal
the basic steps of the two processes

199
00:14:32,69 --> 00:14:35,99
and their differences actual
manufacture is a complicated

200
00:14:35,99 --> 00:14:41,21
and elaborate development of these apparently
simple steps every operation must be

201
00:14:41,21 --> 00:14:45,23
precisely controlled extremely fine
limits of time and temperature

202
00:14:45,23 --> 00:14:46,51
or must be maintained.

203
00:14:47,97 --> 00:14:53,20
Every ingredient used must be of high purity
proportions must be exactly calculated.

204
00:14:53,60 --> 00:14:54,58
When we consider

205
00:14:54,58 --> 00:14:59,05
that every detail must be carried out
with a laboratory precision it becomes

206
00:14:59,05 --> 00:14:59,14
obvious

207
00:14:59,14 --> 00:15:03,99
that only a great chemical organization
can produce huge quantities of rain on

208
00:15:03,99 --> 00:15:08,24
yarns of Dupont quality.

209
00:15:09,40 --> 00:15:11,95
The size alone of the
four The padre on plants.

210
00:15:12,16 --> 00:15:14,51
You have some idea of the
amount of specialized equipment

211
00:15:15,23 --> 00:15:19,37
and scientific craftsmanship needed to
produce each year millions of pounds of

212
00:15:19,37 --> 00:15:24,45
finery on yarn yarns that are converted
by leading textile mills into fabrics

213
00:15:24,45 --> 00:15:26,21
that make garments draperies

214
00:15:26,21 --> 00:15:29,49
and countless other fine
articles found in the apparel

215
00:15:29,49 --> 00:15:32,46
and home furnishing departments
of stores all over America.

216
00:15:33,66 --> 00:15:36,16
Actually these buildings
are not factories.

217
00:15:36,40 --> 00:15:41,11
But giant laboratories where skilled
technicians follow specifications as high as

218
00:15:41,11 --> 00:15:47,40
those required in small experimental equipment
within these walls work craftsman to

219
00:15:47,40 --> 00:15:51,87
whom quality is a creed with the
most modern equipment obtainable.

220
00:15:51,89 --> 00:15:56,47
The interior of this Dupont cellulose
acetate ray on plants reveals a maze of

221
00:15:56,47 --> 00:15:59,77
intricate elaborate apparatus a lab.

222
00:16:00,00 --> 00:16:04,53
Of containers mixtures and other
machinery linked by a network of pipes

223
00:16:04,53 --> 00:16:10,02
and valves to the layman a picturesque
puzzle of queer looking objects of every

224
00:16:10,02 --> 00:16:11,39
shape and size.

225
00:16:11,41 --> 00:16:14,67
But an expert hands precision instruments

226
00:16:14,67 --> 00:16:20,58
that play major roles in the production of
Scion Rayyan yarns here nothing is left

227
00:16:20,58 --> 00:16:26,00
to chaps constant control of every process
is maintained by accurate devices

228
00:16:26,00 --> 00:16:30,91
that check and record every operating
fact of continual checking

229
00:16:30,91 --> 00:16:35,43
and testing throughout every step of the
way is one big factor in Dupont quality

230
00:16:36,20 --> 00:16:36,70
these laboratories

231
00:16:36,70 --> 00:16:41,62
that every building examine the
product of each important process.

232
00:16:41,64 --> 00:16:42,05
Make sure

233
00:16:42,05 --> 00:16:46,29
that nothing passes on for further
treatment until it measures up to the high

234
00:16:46,29 --> 00:16:50,78
standards set and rigid they maintain.

235
00:16:51,74 --> 00:16:55,03
Manufacture of a cause process
right on begins by steeping

236
00:16:55,03 --> 00:16:59,51
or soaking sheets of cellulose the first
step in changing them into the spinning

237
00:16:59,51 --> 00:17:01,57
solution as we saw in the laboratory.

238
00:17:02,40 --> 00:17:06,63
But while the principle is the same as with
the glass beaker here the operation of

239
00:17:06,63 --> 00:17:11,94
steeping is carried out with exacting
precision just the right amount of cellulose

240
00:17:11,94 --> 00:17:17,18
is placed in each compartment of the
specially designed steeping press the sodium

241
00:17:17,18 --> 00:17:20,84
hydroxide solution is checked
repeatedly to be sure it's just right

242
00:17:21,96 --> 00:17:23,46
and the sheets are allowed to soften

243
00:17:23,46 --> 00:17:28,30
and soak for a definite pre-determined
length of time before an automatically

244
00:17:28,30 --> 00:17:33,37
operated hydraulic ram begins to squeeze
out some of the liquid it's pressure is

245
00:17:33,37 --> 00:17:38,18
carefully governed. So is the sheets well
away just so much more wet than when dry.

246
00:17:39,47 --> 00:17:44,55
Even the weather in this room as in all
other operations is man made perfectly

247
00:17:44,56 --> 00:17:48,68
suited at all times to this
particular process every factor

248
00:17:48,68 --> 00:17:52,82
that can affect the ultimate quality of the
re on is scientifically controlled to a

249
00:17:52,82 --> 00:17:58,15
fine degree the soft pulpy sheets poor
through shoots to the floor below to be

250
00:17:58,15 --> 00:17:59,14
shredded into crumbs.

251
00:18:00,00 --> 00:18:04,14
These ingenious shredders gently
crumble of sheets pulling them apart

252
00:18:04,90 --> 00:18:05,97
but not grinding them.

253
00:18:06,27 --> 00:18:11,19
This machine also uniformly distributes
the liquid remaining in the cellulose so

254
00:18:11,19 --> 00:18:16,82
that its action is the same on every crumb
on the floor below the crumbs are poured

255
00:18:16,82 --> 00:18:21,49
into steel cabinets like containers here
the crumbs are stored for aging under

256
00:18:21,49 --> 00:18:26,04
constant temperature every container bears
an accurate record of its contents.

257
00:18:26,27 --> 00:18:29,38
So it may be individually
checked and controlled.

258
00:18:29,40 --> 00:18:32,43
Accurate scientific analysis determines

259
00:18:32,43 --> 00:18:36,74
when the right degree of aging has been
reached at the correct stage the crumbs are

260
00:18:36,74 --> 00:18:37,72
released from storage

261
00:18:37,72 --> 00:18:42,70
and passed on to the next treatment which
we remember is the addition of a liquid

262
00:18:42,70 --> 00:18:44,99
that changes them in
color from white to Ari.

263
00:18:45,46 --> 00:18:50,55
In actual manufacture this process is
carried out in huge rotating churns

264
00:18:50,55 --> 00:18:56,50
that are individually cool to a precise
temperature the snow white cellulose enters

265
00:18:56,50 --> 00:19:00,68
the barrel like interior of the churn which
contains a pipe through which carbon by

266
00:19:00,68 --> 00:19:06,12
itself either is fed this liquid flows
into the churn rotating at a definite rate

267
00:19:06,12 --> 00:19:10,40
of speed for every blending with the
crumbs which gradually darken and color.

268
00:19:11,52 --> 00:19:16,79
Here again close control of every factor
is absolutely necessary if our cellulose

269
00:19:16,79 --> 00:19:21,22
is to make fine rain on the on the speed
of the machinery as closely regulated

270
00:19:22,19 --> 00:19:27,87
exact timing is highly important for proper
air conditioning the air is completely

271
00:19:27,87 --> 00:19:29,95
changed twenty two times every hour

272
00:19:31,42 --> 00:19:34,30
when the process is finished
the cellulose sensate

273
00:19:34,30 --> 00:19:37,10
or orange colored crumbs are
emptied from the churn.

274
00:19:38,24 --> 00:19:41,54
Notice how greatly they've increased
in size and dark and in color

275
00:19:41,54 --> 00:19:42,89
and indication

276
00:19:42,89 --> 00:19:47,24
that they are now ready to be converted
into the spinning solution in the

277
00:19:47,24 --> 00:19:51,12
laboratory we carried out this step by
dissolve in the crumbs in a solution of

278
00:19:51,12 --> 00:19:51,47
water

279
00:19:51,47 --> 00:19:56,64
and the lute sodium hydroxide contained in
a glass beaker in the plant the spinning

280
00:19:56,64 --> 00:19:59,51
solution is made in huge
cylindrical mixing tanks.

281
00:20:00,00 --> 00:20:04,00
Which exact proportions of the
ingredients are accurately maintained.

282
00:20:04,02 --> 00:20:08,87
Each lot produced as thoroughly analyzed
by control laboratories located right in

283
00:20:08,87 --> 00:20:13,29
the plants already upon Rand yarn
enjoys uniform high quality.

284
00:20:13,94 --> 00:20:16,42
Mainly because its quality
is never taken for granted.

285
00:20:16,87 --> 00:20:18,74
It is constantly tested

286
00:20:18,74 --> 00:20:23,73
and proved throughout every step of its
scientific manufacture to ensure the

287
00:20:23,73 --> 00:20:26,51
highest possible degree of
uniformity in the spinning solution

288
00:20:26,51 --> 00:20:32,20
and in the finished yarn the various lots
are blended together each huge blending

289
00:20:32,20 --> 00:20:36,30
tank is equipped with positive starting
blades that surly mix the solution.

290
00:20:36,67 --> 00:20:41,46
At this point the desired degree of luster
in the finished yarn is also permanently

291
00:20:41,46 --> 00:20:45,79
fixed if brilliance is wanted the blended
solution is used without further

292
00:20:45,79 --> 00:20:48,63
treatment the addition
of a special pigment

293
00:20:48,63 --> 00:20:51,87
or certain types of on
oil changes solution so

294
00:20:51,87 --> 00:20:54,92
that the yarn it produces
will be dull in appearance.

295
00:20:54,94 --> 00:20:58,99
The amount of the luster on the added
determines a final degree of dullness in the

296
00:20:58,99 --> 00:20:59,64
finished yarn.

297
00:21:00,18 --> 00:21:04,66
After blending the spending solution is
allowed to ripen for an exact period of

298
00:21:04,66 --> 00:21:09,08
time to bring it to just the right condition
for spinning unless it is properly

299
00:21:09,08 --> 00:21:12,02
aged the yarn it produces
will suffer in quality.

300
00:21:12,19 --> 00:21:16,96
So during its stay in the aging tanks
the solution is regularly tested

301
00:21:16,96 --> 00:21:22,43
and checked in precision Bill Press's all
foreign matter is completely removed by a

302
00:21:22,43 --> 00:21:25,55
thorough filtering not
once but again and again.

303
00:21:26,13 --> 00:21:30,56
Throughout every stage of manufacture
the purity of the spending solution is

304
00:21:30,56 --> 00:21:31,78
constantly safeguarded.

305
00:21:32,30 --> 00:21:36,27
Each piece of equipment is constructed
of metals specially selected to resist

306
00:21:36,27 --> 00:21:36,78
corrosion

307
00:21:36,78 --> 00:21:41,91
and contamination of the products being
handled the pipelines of valves tanks

308
00:21:41,91 --> 00:21:46,10
mixtures and other machines are
designed and built to make the purest

309
00:21:46,10 --> 00:21:47,56
and finest spending solution

310
00:21:47,56 --> 00:21:50,94
that science can produce the
only kind of spending solution

311
00:21:50,94 --> 00:21:55,36
that measures up to Dupont high ridges
specifications before it is approved for

312
00:21:55,36 --> 00:21:59,95
spending it with top quality
or a on the R.. The X..

313
00:22:00,00 --> 00:22:03,49
He was spinning of the solution is one of
the most fascinating operations in all

314
00:22:03,49 --> 00:22:05,96
industry. We saw previously.

315
00:22:06,27 --> 00:22:10,30
How are things stream of the solution
changes to a core strand of crude ray on

316
00:22:10,30 --> 00:22:12,14
when dropped into a hardening bath

317
00:22:13,24 --> 00:22:17,73
but the crude way on formed in this way
is entirely unsuited for making cloth as

318
00:22:17,73 --> 00:22:20,07
can be readily seen by
comparing it was true.

319
00:22:20,08 --> 00:22:25,20
Re on yachts to make this yarn requires
a specially designed precision built

320
00:22:25,20 --> 00:22:28,42
apparatus. That is an outstanding
example of modern machinery.

321
00:22:28,92 --> 00:22:33,08
That liquid passes through still one more
filter before it emerges from minute

322
00:22:33,08 --> 00:22:37,93
openings in a tiny nozzle called a spinner
wreck how fine Are these openings.

323
00:22:38,19 --> 00:22:43,11
Well generally they range in size from
five thousands to two Thousands of an inch

324
00:22:43,11 --> 00:22:47,67
the thickness of a human hair each
hole forms an individual filament

325
00:22:47,67 --> 00:22:49,85
and there may be any
number up to four hundred

326
00:22:49,85 --> 00:22:55,00
or more of them in a single symbol legspinner
red notice how the liquid solution

327
00:22:55,00 --> 00:22:55,72
coagulates

328
00:22:55,72 --> 00:23:00,34
when the spinner red is lowered into the
spinning back an expert hand skillfully

329
00:23:00,34 --> 00:23:03,22
leads the yarn through
a series of guides off

330
00:23:03,22 --> 00:23:08,29
and around a rotating glass we then down
through a funnel into a four Ling part

331
00:23:08,29 --> 00:23:10,69
which collected.

332
00:23:10,71 --> 00:23:15,21
Each thread like filament forms immediately
as a spinning solution leaves the holes

333
00:23:15,21 --> 00:23:19,74
in the spinner at the speed of the glass
wheel largely determines the thickness of

334
00:23:19,74 --> 00:23:23,80
the R.. Although this characteristic
also depends upon the size

335
00:23:23,80 --> 00:23:25,37
and number of the spinner it holds

336
00:23:25,37 --> 00:23:29,99
and the amount of spinning solution force
through them for a minute the collecting

337
00:23:29,99 --> 00:23:34,26
part rotate to the very high speed from six
to ten thousand revolutions per minute

338
00:23:35,15 --> 00:23:36,97
the rotation twists the filaments together

339
00:23:36,97 --> 00:23:40,23
and the yarn is distributed
alternately from top to bottom.

340
00:23:40,57 --> 00:23:41,22
So

341
00:23:41,22 --> 00:23:44,96
that it will lie a properly against the
wall of the pot to form a symmetrical cake.

342
00:23:46,55 --> 00:23:48,32
When removed from the part of the cake

343
00:23:48,32 --> 00:23:51,43
or a on consist of about twenty
nine percent yarn by weight

344
00:23:51,43 --> 00:23:56,37
and seventy one percent spinning
bath liquid which must be removed at

345
00:23:56,38 --> 00:23:59,70
pre-determined intervals a
cake of fine quality yarn is.

346
00:24:00,00 --> 00:24:05,45
Move from each one of hundreds
of spinning machines.

347
00:24:05,47 --> 00:24:10,67
In other plants your pond acetate re on a
sponge by yet another method the spinning

348
00:24:10,67 --> 00:24:15,07
solution made from cellulose as a fade by
a different chemical process known as a

349
00:24:15,07 --> 00:24:19,68
cellulose acetate process is forced to
tiny holes in a spinner at located about

350
00:24:19,68 --> 00:24:21,69
fifteen feet above the level of the floor

351
00:24:22,66 --> 00:24:27,11
when the solution passes through a column
of warm air one ingredient as a tone

352
00:24:27,11 --> 00:24:27,81
evaporates

353
00:24:27,81 --> 00:24:33,28
and the liquid solidifies to form a slender
filaments of rail by the time they

354
00:24:33,28 --> 00:24:38,06
reach the bottom of the warm air
column the filament SAR perfectly dry.

355
00:24:38,08 --> 00:24:41,42
Here they are collected and guided
out of the column to a device

356
00:24:41,42 --> 00:24:46,04
that winds the yarn and bobbins.
The acetate ray on yarn.

357
00:24:46,22 --> 00:24:48,29
As it comes in the spinning
machine is a finished product.

358
00:24:48,71 --> 00:24:51,39
After twisting it is ready for weaving

359
00:24:51,39 --> 00:24:56,10
or knitting into fine fabrics each
bobbin is numbered for easy positive

360
00:24:56,10 --> 00:25:00,58
identifications so that every bit of
yarn can be traced back to the machine

361
00:25:00,58 --> 00:25:02,59
that made it.

362
00:25:03,74 --> 00:25:08,32
All Japan first cause process Rayyan is
also carefully marked for reference before

363
00:25:08,32 --> 00:25:11,11
passing on to the finishing operations.

364
00:25:11,13 --> 00:25:15,55
Repeated a thorough washing with
pure warm water gradually softens

365
00:25:15,55 --> 00:25:16,83
and cleanses the iron

366
00:25:16,83 --> 00:25:21,63
and gives it a smooth pleasant feeling
much of the moisture is removed in a

367
00:25:21,63 --> 00:25:23,61
specially designed machine colors

368
00:25:23,61 --> 00:25:28,43
and critical extract of each cake is placed
in an individual chamber which spends

369
00:25:28,43 --> 00:25:33,40
like a top at extremely high speeds throwing
off water without harming the irons

370
00:25:33,40 --> 00:25:35,57
fine texture and construction.

371
00:25:35,59 --> 00:25:40,51
The final drying is accomplished an automatic
tunnel Evans' through which the iron

372
00:25:40,51 --> 00:25:44,15
travels on conveyors and exact
degree of heat is maintained.

373
00:25:44,32 --> 00:25:47,60
So that the yarn is dried
gently and slowly.

374
00:25:47,62 --> 00:25:52,26
Now the iron is ready for winding into the
form desired by the fabric manufacturers

375
00:25:52,26 --> 00:25:53,99
and the bobbins are so designed

376
00:25:53,99 --> 00:25:58,36
that each stage of the processing strain
is eliminated this permits proper

377
00:25:58,36 --> 00:25:59,93
attention and twisting Kone.

378
00:26:00,00 --> 00:26:05,49
To bring in skinny from raw material to
finished product all Du Pont re on whether

379
00:26:05,49 --> 00:26:06,67
made by the vest because process

380
00:26:06,67 --> 00:26:12,68
or the cellulose acetate process is continually
checked by a rigid testing routine.

381
00:26:12,70 --> 00:26:17,47
A continuous check on winding tension is
made by periodically testing the tension

382
00:26:17,47 --> 00:26:21,38
of the running our specimen cones
are regularly picked at random

383
00:26:22,15 --> 00:26:23,92
and rewound on a special machine

384
00:26:23,92 --> 00:26:28,83
that permits thorough inspection of the
continuous yards a highly trained operator

385
00:26:28,83 --> 00:26:32,24
expertly examines the rail and of the
passes in front of a black background

386
00:26:33,18 --> 00:26:34,23
that easily shows up any

387
00:26:34,23 --> 00:26:38,87
and perfections still other pursuits
in built testing appliances make sure

388
00:26:38,87 --> 00:26:42,90
that the physical qualities of samples
of every lot measure up to Dupont's high

389
00:26:42,90 --> 00:26:47,92
standards testing for yardage is
accurately accomplished by a Winding Refn

390
00:26:48,61 --> 00:26:53,17
that turns out an exact degree of speed
and measures the yarn precisely.

391
00:26:53,18 --> 00:26:58,32
Measured specimens of known lengths are
then weighed on a sensitive gram scale to

392
00:26:58,32 --> 00:27:01,78
ensure the uniformity of the
are the amount of stretch

393
00:27:01,78 --> 00:27:06,48
or elongation of any textile material as
well as its tensile strength are both of

394
00:27:06,48 --> 00:27:09,24
considerable importance because
they affect the serviceability

395
00:27:09,24 --> 00:27:14,84
and wearer of the fabrics made from this
testing device precisely records the

396
00:27:14,84 --> 00:27:19,04
amount of twist per inch in any given
specimen of the arc the construction of

397
00:27:19,04 --> 00:27:23,27
practically every type of fabric graded
depends on how the yarn is twisted.

398
00:27:23,65 --> 00:27:28,90
So uniform twisting is highly important
inspection of the yarn of the passes over a

399
00:27:28,90 --> 00:27:33,17
strong light within a dark room
is still another Dupont control.

400
00:27:33,97 --> 00:27:36,02
By the expert eyes of skilled operators

401
00:27:36,02 --> 00:27:41,89
and the imperfection is immediately detected.
Nothing but verify. Action gets by.

402
00:27:41,91 --> 00:27:46,54
But with this organization careful service
inspection isn't enough by any means

403
00:27:46,54 --> 00:27:49,78
thorough microscopic
examination tells their vision

404
00:27:49,78 --> 00:27:52,96
or story of what's beneath
the surface of the.

405
00:27:52,97 --> 00:27:58,02
Cross sections of samples from every lab
produced are prepared by making tiny wax

406
00:27:58,02 --> 00:27:59,67
candles with a strip of yarn.

407
00:28:00,00 --> 00:28:04,56
Warming the work in the center of the
candle is then accurately cut into a paper

408
00:28:04,56 --> 00:28:08,97
thin slices each of which contains a
tiny cross-section of yarn for its core

409
00:28:09,98 --> 00:28:11,66
when a slice is placed
in a powerful microscope

410
00:28:12,48 --> 00:28:16,57
and the focus properly adjusted the
structure of each tiny filament is plainly

411
00:28:16,57 --> 00:28:20,36
Ready To the untrained eye
such a picture means nothing.

412
00:28:21,35 --> 00:28:23,67
But to the Depart expert the size shape

413
00:28:23,67 --> 00:28:28,17
and arrangement of every fiber tell a
definite story about the quality of the yarn

414
00:28:28,17 --> 00:28:29,72
being tested.

415
00:28:29,74 --> 00:28:32,50
Notice the difference between
lustrous Rayyan and Dollar A

416
00:28:32,50 --> 00:28:33,88
and as revealed by the microscope.

417
00:28:34,46 --> 00:28:38,26
The tiny specks of pigment in the sample
on the right are embedded within each

421
00:28:52,25 --> 00:28:56,47
Even one of those passed every other test
all your Padre on is carefully checked

422
00:28:56,47 --> 00:29:01,79
again before shipping to you this game
inspection may appear hurried and haphazard.

423
00:29:02,15 --> 00:29:04,79
But with these girths years of training

424
00:29:04,79 --> 00:29:07,77
and knowing just what to
look for have made a hand

425
00:29:07,77 --> 00:29:10,22
and I super sensitive

and test every step of the way from the
raw materials to the finished product.

431
00:29:30,97 --> 00:29:32,28
Nothing is taken for granted.

432
00:29:33,35 --> 00:29:37,38
The result of each process is scientifically
analyzed by accurate fact finding

433
00:29:37,38 --> 00:29:42,69
