Strength and Elongation of Cotton, Polyster, and Polyester /Cotton Blends at Different Stages of Manufacture

Abstract

Investigations are reported comparing the relative strength and elongation of Tetoran (polyester), cotton, and 67% Tetoran/33% cotton blend material at different stages of manufacture (i.e., single yarn, double yarn, multiple strand, and fabric). The improvements in strength and elongation from doubling are more prominent in blend and Tetoran yarns than in cotton yarn. The strength losses from short to long specimen and from single to multiple strand are more marked in the blend than in cotton. At the same time, the assistance derived from the interlacement of the weft is more in the blend than in cotton, as a result of which the blend, though inferior in strength to cotton at the yarn, becomes comparable to it at the fabric.
