Study on tensile properties of ATY

To figure out ATY′s tensile properties and related structure characteristics,two kinds of ATY were designed and spun.The test results showed that when compared with common filaments or twisted filaments of identical specifications,ATY exhibited obviously loss in both strength and elongation at break.This may be attributed to the forming of disordered structure when the flat smooth filaments were being textured.Further multi-texturing made the disordered structure more serious and hence led to greater loss in strength and elongation at break.There was an obvious difference in stretch curve between ATY and common filaments,ATY′s curve showed a straight line basically,and had no obvious yield point or smooth curve but frequently appeared zigzag tiny waves,reflecting the snarling structure inherent in ATY.
