摘要
PPS/PA66/SiO_2系聚苯硫醚与尼龙66和二氧化硅共混纤维,采用分散染料对其进行染色工艺试验,讨论了染色温度和时间,PPS纤维改性等工艺对上染率的影响,测试了分散染料染色后纤维的断裂强力和皂洗色牢度。结果表明,该共混纤维分散染料优化染色条件为:染料2%(omf)、扩散剂NNO 1 g/L、磷酸二氢钾2 g/L、渗透剂2mL/L、pH值5、浴比1:100,染色温度140℃,时间50min;染料的上染率可达到73%,染色纤维的皂洗色牢度达到5级,染色纤维强力损伤较小。
PPS/PA66/SiO2 blended fiber is dyed with disperse dyes, the influences of dyeing temperature and time, and modification of PPS fiber on color yield are discussed, and the breaking strength and soaping fastness after disperse dyeing are tested. The high temperature and high pressure dyeing process of PPS fiber with disperse dyes is： dye 2%（omf）, diffusing agent NNO 1 g/L, potassium dihydrogen phosphate 2 g/L, penetrating agent 2 mL/L, dyeing at 140 ℃ for 50 min with pH value 5 and bath ratio 1 ： 100. The PPS/PA66/SiO2 dyeings feature good results with color yield of 73%, soaping fastness of Grade 5 and low strength loss.
