摘　　要：模仿氨纶干法纺丝过程中的条件,研究氨纶成品复丝抱合力大小的主要影响因素。通过分析氨纶的DSC图谱、测定氨纶的软化温度、观察氨纶复丝抱合的横截面等方法,明确加热温度、加热时间、纺丝设备是氨纶复丝抱合力的主要影响因素;得出生产氨纶复丝的最佳工艺应该是加热温度为氨纶软化温度220℃,加热时间为20 s。此外,合适的纺丝设备对氨纶复丝抱合力也会有一定程度的影响。The main factors influencing cohesion of Spandex multifilament in dry spinning process were researched.By analyzing the DSC spectrum of polyurethane,determining the softening temperature of Spandex,observing the cross-section of the Spandex samples etc.,author definited that heating temperature,heating time,spinning equipment were the main effect factors for Spandex cohesion.It had been shown that the best technology for Spandex multifilament cohesion was the heating temperature was softening temperature 220 ℃,the heating time was about 20 s.In addition,the difference of spinning device had a significant influence on the cohesion between Spandex multifilaments.
