摘要：
Solvent texturing experiments are described using partially oriented polyester yarn treated in sequential steps of twisting, solvent setting, and untwisting. Effects of several parameters such as solvent treatment time, pre-immersion solvent, and drawing on the shrinkage values are discussed. Pre-immersion in the solvent before twisting allows faster diffusion into the yarn but ''sets'' the structure prematurely. Drawing of the twisted, solvent-set structure dilutes the twist and disrupts the structure, reducing the crimp. The potential energy saving over heat-texturing is calculated. This study is intended as a precursor for continuous solvent texturing.
