The exact cause of tendering during the lime boil, particu-larly in high pressure kiers has been a much discussed point.Experimental investigation shows that lime at a high temperaturein the presence of the oxygen of the air will convert cellulose into 91 82 TEXTILE CHEMISTRY AND DYEING. oxycellulose, a substance having but little structural strength.Kier tendering is undoubtedly due to the existence of these con-ditions in the kier, commonly brought about by an insufficientamount of liquor. 0=0=0
