Effects of texturing entropy change on tensile properties of textured yarn

Texturing process will led to increasing of filaments system entropy,which will further influence the structure and the properties of the textured yarn dramatically.To indicate the relationship between texturing entropy change and the stretching properties,10 textured sample yarns were designed and spun,and then tested.The results showed that along with the increasing both of the entropy change and disorderness degree,both the loss of strength and the loss of elongation at break grew quickly,up to the 50%.When multi-differential shrinking was introduced,the ATY's loss of strength curve was flatten,as well as its loss of elongation at break curve was laid down.At the same time,both of the entropy change and disorderness degree kept growing.
