Abstract
A hydrolizable polymer-containing textile article and method for producing the same is provided that has been chemically modified by treating the article with certain branched chain amines to reduce the strength of the fibers contained therein, thus rendering the article less prone to the formation of objectionable pill balls, thereby increasing wearer comfort and retaining the desired appearance of the article, and thereby extending the useful life of the article.
