QUALITY IMPROVED POLYESTER OR NYLON FIBER AND QUALITY IMPROVING METHOD

摘要

Textile materials formed of polyester or nylon fibers having improved durable soil release and moisture transport characteristics are provided by application to the textile material of at least about 0.001 weight percent of a cellulose acetate polymeric constituent having a degree of substitution of the acetyl moiety of from about 0.9 to about 2. 3. Such cellulose acetate polymeric constituent are represented by the formula ##STR1## WHEREIN X IS AN INTEGER OF AT LEAST 50, N IS AN INTEGER OF FROM ABOUT 2.1 TO ABOUT 0.7, AND THE EXPRESSION 3-N IS THE DEGREE OF SUBSTITUTION OF THE ACETYL MOIETY. The cellulose acetate polymeric constituent can be applied to the fabric from a pad bath containing the polymeric constituent and a solvent capable of solubilizing the polymeric constituent; by exhaustion techniques during the dyeing of the textile material; or by exhaustion techniques from an aqueous admixture containing finely dispersed particles of the cellulose acetate polymeric constituent.
