从原料、工艺、设备等方面入手,对影响锦纶6拉伸变形丝(DTY)染色性能的主要因素进行分析和试验论证。实践证明:切片是影响DTY染色性能的关键因素,纺丝温度及速度、DTY热箱温度、拉伸比对DTY丝上染率影响较大,预取向丝(POY)、DTY质量稳定性对染色均匀性影响也较大。
Starting from raw materials, technology, equipment and other aspects, the main factors influencing the dyeing performance of nylon 6 tensile textured yarn (DTY) are analyzed and demonstrated. Practice has proved that the slicing is the key factor to affect the dyeing performance of DTY. The spinning temperature and speed, DTY hot box temperature and draw ratio have a great influence on the dyeing rate of DTY yarn. Pre-oriented yarn (POY), DTY quality stability Uniformity is also more affected.
