Estimating the term…
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.
A process for imparting improved, durable soil release and moisture transport characteristics to a textile material formed of polyester or nylon fibers which comprises applying an effective amount of a liquid admixture consisting essentially of from about 0.001 to about 10 weight percent of a cellulose acetate polymeric constituent and a solvent constituent capable of solubilizing said cellulose acetate polymeric constituent, to provide a resulting wet textile material containing at least about 0.001 weight percent of said cellulose acetate polymeric constituent, said cellulose acetate polymeric constituent being characterized as having a degree of substitution of the acetyl moiety of from about 0.9 to about 2.3 and represented by the formula ##STR6## wherein x is an integer of at least about 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, and drying the resulting wet textile material for a period of time effective to remove substantially all of the solvent constituent and provide a dry textile material containing said cellulose acetate polymeric constituent.
A process for imparting improved, durable soil release and moisture transport characteristics to a textile material formed of polyester fibers during a dyeing operation wherein the textile material is contacted with an aqueous dye admixture containing water, a dispersed dye stuff, a minor amount of acetic acid and a leveling agent which comprises incorporating into said aqueous dye admixture a minor effective amount of a cellulose acetate polymeric constituent so as to provide at least about 0.001 weight percent of said polymeric constituent on said textile material, said cellulose acetate polymeric constituent being characterized as having a degree of substitution of the acetyl moiety of from about 0.9 to about 2.3 and represented by the formula ##STR7## wherein x is an integer of from about 100 to about 200, 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;
A textile material formed of polyester fibers having improved durable soil release and moisture transport characteristics consisting essentially of a polyester textile material substrate having incorporated thereon from about 0.001 to about 10 weight percent of a cellulose acetate polymeric constituent, said cellulose acetate polymeric constituent being characterized as having a degree of substitution of the acetyl moiety of from about 0.9 to about 2.3 and represented by the formula ##STR8## wherein x is an integer of at least about 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.
A process for imparting improved, durable soil release and moisture transport characteristics to a textile material formed of polyester or nylon fibers which comprises contacting said textile material with an aqueous dispersion consisting essentially of water and a minor effective amount of a cellulose acetate polymeric constituent for a period of time effective to provide at least about 0.001 weight percent of said polymeric constituent on said textile material, said cellulose acetate polymeric constituent being characterized as having a degree of substitution of the acetyl moiety of from about 0.9 to about 2.3 and represented by the formula ##STR9## wherein x is an integer of at least about 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;
