摘要
介绍了异染异缩型涤纶变形丝的生产技术及工艺流程，讨论分析了异染、异缩原理和纺丝速度、纺丝温度、侧吹风风速、风温、风湿；纺丝油剂及上油率；冷拉伸倍数、拉伸倍数、拉伸温度、定型温度等工艺参数对其品质和异染、异缩效果的影响。
The technique and process for producing differential dyeable and bi-shringkage PET textured yarn are introduced with disscussion on the differential dyeing and shringking mechanism and influence of speed in spinning,spinning temperature,lateral blowing, temperature and humidity of the quench air,spin-finish and its take-up,cold-draw ratio and ratio. temperature of drawing and setting etc.on the fibers quality and effects of differential dyeing.
