Synthesis, Characterization, Application, and Evaluation of Reactive Sizes for Cotton Warps

Abstract

The purpose of this research has been to investigate the weaving properties of cotton yarns treated with three newly developed reactive sizing agents. N-methlyocarbamoylethyl starch, N-methlyocarbamoylethyl starch + poly vinyl alcohol (PVA), and N-methlyocarbamoylethyl starch + PVA + melamine formaldehyde have been studied as durable, non-removable sizing agents. Extensive work has been conducted to accomplish the objectives of the current research. The experimental activities have included: developing new reactive sizes; spinning a range of cotton yarns with three levels of twist multiple; preparing and applying size solution; testing mechanical and physical characteristics of sized yarns to evaluate their weavability; evaluating the stability of the sizing agents in woven structures; and performing statistical analyses to investigate the effect of size type, twist level, and solid concentration in the size bath on several yarn properties.
