中空涤纶针织物的高温染色工艺研究

简单介绍了常用涤纶织物的染色方法,并通过正交试验,分别选择固色温度、助剂质量浓度、固色时间三因素的三个水平,确定出分散染料染中空涤纶针织物时的最佳高温染色工艺为:染料浓度2%(o.w.)f,浴比1∶20,固色温度130℃,固色时间60 min,助剂质量浓度1 g/L。对染色前后织物的顶破强力、保暖性能、透气性能进行了测试,得出染色后织物的强力没有明显变化,保暖性有所提高,透气性略微下降。

High-Temperature Dyeing of Hollow Polyester Fiber Knit Fabric

This paper briefly introduces some common dyeing methods of polyester fiber fabric, and using orthogonal test to ensure the optimal high-temperature dyeing of hollow polyester fiber knit fabric： dye depth 2 %（o.w.f）, bath ratio 1：20, dyeing temperature 130 ℃, dyeing time 60 min, mass concentration of additive 1 g/L. The bursting strength, warmth retaining property and air-permeability of both dyed and non-dyed fabrics are tested, it finds that the dyed fabrics strength unchanged, warmth retaining property increased and air-permeability decreased slightly.
