Sizing of Spun Viscose Warp Yarns

Abstract

This is the last of a series of papers which describe certain parts of a program, of research on warp sizing conducted by Textile Research Institute, Inc. Part I— "Effect of Stretch in Slashing," and Part II—"Abrasion Testing of Sized Warp Yarns," appeared in the January, 1945, issue of this JOURNAL. Parts III and IV— "Application of Synthesize" and "Application of Methyl Cellulose," were presented in the February issue. A summary report of the entire program of research on the sizing of spun rayon warp yarns will be ready for distribution about May 1.
