【摘要】 本文研究了阳离子可染涤纶细特卷绕丝结构特性。实验表明:在卷绕丝的名义单丝纤度达到1.55分特(d-Tex)时,其模量、结晶度等结构性能参数明显增大,沸水收缩率出现极大值,此时卷绕丝结构的形成主要由应力诱导结晶效应支配。更多还原

【Abstract】 In this article, the structural formation of CDPET fine undrawn filaments is investig-ated. The results show that when the denier of the filament reaches 1.55 dtex, the param-eters such as modulus and crystallinity incrasing obviously, and boiling water shrinkagereaching its maximum value. At the same time, the structural formation of the undrawn fi-laments is mainly controlled by the tension- induced effect of crystal kinetics.更多还原
