27—THE PILLING OF PLAIN- AND RIB-KNIT WOOL FABRIC

Abstract

Experiments are described which show the effect of fabric construction, yarn count, and twist on the pilling of plain- and rib-knit fabrics. The fabrics were knitted from two-fold worsted yarns spun from 64s tops. The results show that a comparison of the pilling properties of two fabrics, made from wool of the same quality and finished by the same methods, depends on the wales and courses per inch in the fabric, and the yarn count and twist. Also, the changes in fabric compactness and yarn count and twist necessary to produce an appreciable reduction in pilling are shown to be comparatively large. Results of wearing triab are discussed together with the effect of anti-pilling treatments and their disadvantages.
