Textile materials having durable soil release and moisture transport characteristics and process for producing same

摘要

{PG,1 Textile materials formed of polyester or nylon fibers having improved durable soil release characteristics are provided by application to the textile material of at least about 0.001 weight percent of a water-soluble cellulose acetate polymeric constituent having a degree of substitution of the acetyl moiety of from about 0.6 to about 0.9. Such water-soluble cellulose acetate polymeric constituent are represented by the formula {r1 {tc,1 {rb {ob,6 {s,15 {sd,5 C{HD 6{L H{HD 7{L O{HD 2{M,1 {AB,22 (OH){HD n{mr,1 {ab,66 (O{M,2 {AD,0 O{MR,2 C{AB,4 CH{HD 3{L ){HD 3{31 n{s,15 {my,1 {us,5 {cb,6 {bl,888 {s,6 {hd x{re {PS {PS WHEREIN X IS AN INTEGER OF AT LEAST 50, N IS AN INTEGER OF FROM ABOUT 2.4 TO ABOUT 2.1, AND THE EXPRESSION 3{31 N IS THE DEGREE OF SUBSTITUTION OF THE ACETYL MOIETY. The water-soluble cellulose acetate polymeric constituent can be applied to the fabric from an aqueous pad bath containing the polymeric constituent; by exhaustion techniques during the dyeing of the textile material; or as an aqueous spray.
