Textile Chemist and Colorist 31, No. 6: 27+, 5 pages (June 1999). English. Researchers studied the role of nylon in pilling in a commercial wool/cotton/nylon knit fabric. The study also involved the development of fabric blends without nylon, substitution of chlorinated wool for unchlorinated wool, and use of functional fabric finishes to increase fabric pilling resistance. The results of pilling tests measured by an ASTM standard test correlated well with an image analysis method. Fabric blends with chlorinated wool showed less tendency to pill than did fabric blends with unchlorinated wool, but unchlorinated wool showed higher resistance to pilling when finished with soft acrylic resins combined with dimethylsiloxane, manmade waxes, glyoxal, and melamine. Fabrics showed less pilling without nylon in the blend. Wool/cotton blend fabrics showed resistance to pilling when treated with appropriate finishes. 13 refs.
