Abstract
A PROCESS FOR FINISHING A FABRIC CONTAINING HIGHLY TWISTED CONTINUOUS FILAMENT POLYCARBONAMIDE YARNS WHEREIN AT LEAST 50 MOL PERCENT OF THE REPEATING UNITS ARE OF THE FORMULA: -NH-1,4-CYCLOHEXYLENE-CH2-1,4-CYCLOHEXYLENE-NH-CO-(CH2)10-COWITH AT LEAST 70% BY WEIGHT OF THE DIAMINO CONSTITUENT OF THE REPEATING UNITS BEING A TRANS-TRANS STEREOISOMERIC CONFIGURATION, COMPRISING: (A) STABILIZING THE FABRIC BY HEATING IT IN OPEN WIDTH IN A MEDIUM SELECTED FROM THE GROUP CONSISTING OF STEAM, AIR OR WATER TO INDUCE FROM ABOUT 5 TO 20% SHRINKAGE IN BOTH WARP AND FILLING BASED ON GREIGE FABRIC DIMENSIONS; (B) EXPOSING THE FABRIC TO AN ACIDIC AQUEOUS BATH CONTAINING O-PHENYLPHENOL NEAR THE BOIL; (C) REMOVING THE O-PHENYLPHENOL FROM THE FABRIC BY TREATING THE SAME WITH AN AQUEOUS ALKALINE BATH AT A TEMPERATURE NEAR THE BOIL, RINSING THE FABRIC AND DRYING THE SAME, THE AMOUNT OF O-PHENYLPHENOL IN THE BATH BEING BETWEEN 1/2 TO 3/4 OF THE TOTAL AMOUNT OF O-PHENYLPHENOL INDICATED BY THE FOLLOWING EQUATION:
Y=10.1X-250
WHEREIN Y IS THE BATH-TO-FABRIC WEIGHT RATIO AND X IS THE PERCENT BY WEIGHT OF THE AMOUNT OF O-PHENYLPHENOL IN THE BATH BASED ON THE WEIGHT OF THE FABRIC.
Y=10.1X-250
WHEREIN Y IS THE BATH-TO-FABRIC WEIGHT RATIO AND X IS THE PERCENT BY WEIGHT OF THE AMOUNT OF O-PHENYLPHENOL IN THE BATH BASED ON THE WEIGHT OF THE FABRIC.

PUBLISHED MARCH 7, 1972 T896,012 PROCESS OF MODIFYING POLYCARBONAMIDE FIBERS WITH ORTHOPHENYLPHENOL Jose J. Rufino, Geneva, Switzerland, assignor to E. I. du Pont de N emours and Company, Wilmington, Del. Filed Dec. 16, 1970, Ser. No. 98,876 Int. Cl. D06m 13/00 US. Cl. 8130.1 No Drawing. 14 Pages Specification A process for finishing a fabric containing highly twisted continuous filament polycarbonamide yarns wherein at least 50 mol percent of the repeating units are of the formula:
with at least 70% by weight of the diamino constituent of the repeating units being a trans-trans stereoisomeric configuration, comprising:
(A) stabilizing the fabric by heating it in open width in a medium selected from the group consisting of steam, air or water to induce from about 5 to 20% shrinkage in both warp and filling based on greige fabric dimensions;
(B) exposing the fabric to an acidic aqueous bath containing o-phenylphenol near the boil;
(C) removing the o-phenylphcnol from the fabric by treating the same with an aqueous alkaline bath at a temperature near the boil, rinsing the fabric and drying the same,
the amount of o-phenylphenol in the bath being between /2 to of the total amount of o-phenylphenol indicated by the following equation:
wherein Y is the bath-to-fabric Weight ratio and X is the percent by weight of the amount of o-phenylphenol in the bath based on the weight of the fabric.
