The structural causes of the dyeing variations of nylon 66 yarn subjected to the false‐twist texturing process

摘要

AbstractThe structural variations in nylon 66 caused by heat and the mechanical action of the false‐twist texturing process have been studied by measuring dyeing rates with Durazol Blue 2R, the determination of density, x‐ray orientation, and lateral order, and also by consideration of x‐ray small‐angle scattering data. It is concluded that the morphologic units are probably shish‐kebabs with straight‐chain cores between which the dye
