STUDIES ON THE SIZING OF ACETATE FILAMENT YARN

Relation of the aparent stiffness of sized warp to the “Chika” defects in acetate filament fabrics were studied and the following results were obtained.1. It is found that the “Chika” defects in acetate continuous filament fabrics are caused by the highly stiffened parts of the sized warp and that the “Chika” could be prevented by limiting stiffness of the sized warp.2. Stiffness of the sized yarn depends on the magnitued of the size pick up and the concentration of the size solution.Our “Chika” seems to be the same plenomenon as “Teary” described in “The Fabric Defects” McGraw Hill Co..
