涤纶织物的退浆、碱减量和染色一浴加工
|
摘要
采用氢氧化钠和耐碱分散染料用于涤纶织物的退浆、碱减量和染色一浴法加工。讨论了氢氧化钠、分散剂和耐碱分散染料用量,处理温度和时间等因素对涤纶织物K/S值、失重率和染色特征值的影响,测试了织物的强力、形貌和染色牢度。结果表明,染料质量分数为1%(omf)时,优化的一浴法工艺为:NaOH10 g/L,分散剂2 g/L,在130℃保温处理60 min。处理后纤维试样表面的浆料得到去除,同时纤维获得较好的碱减量效果。织物失重率达到23.85%,强力损失为27.70%,耐洗和耐摩擦色牢度均可达到4~5级。
Sodium hydroxide and alkali-resistant disperse dyes are applied to one bath desizing,alkali deweighting and dyeing of polyester fabrics.The effects of the concentrations of sodium hydroxide,dispersing agent and alkali-resistant disperse dyes,as well as temperature and time on K/S value,weight loss and color characteristics value of polyester fabrics are analyzed.The strength,morphology and color fastness of the fabric are tested.The results show that the optimal process is sodium hydroxide10 g/L,dispersing agent 2 g/L,treating at 130 ℃ for 60 min when the concentration of alkali-resistant disperse dye is 1%(omf).After one bath treating,the size on fabric surface is removed effectively,and the fibers obtain a good alkali deweighting effect.The weight loss and strength loss rates of treated fabric reach 23.85%and 27.70%,respectively.The color fastnesses to washing and rubbing of dyed fabrics reach Grade 4~5.
