涤纶碱减量和染色咪唑类离子液体一浴加工
|
摘要
采用三只耐碱分散染料和咪唑类离子液体(10-10)在高温条件下对涤纶进行碱减量和染色一浴加工。研究氢氧化钠、10-10和染料用量,以及温度和时间等工艺因素对涤纶减量率、K/S值和色光的影响,测试了涤纶织物的强力和表面形态。研究结果表明,涤纶织物的减量率随氢氧化钠、10-10用量以及温度和时间的增加而提高,分散橙HA耐碱性稍差,分散红HA-3B和分散蓝HA具有较强的耐碱性。涤纶织物染色和碱减量一浴法优化工艺为:氢氧化钠2 g/L,10-10 0.5×10~(-4)mol/L,130℃保温60 min。处理后涤纶织物的减量率约为16%,强力损失约为16%,纤维表面被"剥蚀"。
Three alkali-resistant disperse dyes and one imidazole ionic liquid(10-10) are applied to one bath alkali deweighting and dyeing process of polyester fabric. The effects such as dosages of sodium hydroxide, 10-10 and disperse dyes, temperature and time of alkaline deweighting on weight loss,K/S value and shade are studied. The strength loss and surface morphology of the treated fabrics are also tested. The results show that the weight loss of polyester fabrics is increased with the increase of dosages of sodium hydroxide and 10-10, as well as the temperature and time of alkaline deweighting.The alkali-resistant performance of Disperse Orange HA is poorer than that of Disperse Red HA-3B and Disperse Blue HA. The optimal dyeing and alkaline deweighting process in one bath is sodium hydroxide 2 g/L, imidazole ionic liquid 0.5×10~(-4)mol/L, treating at 130 ℃ for 60 min. The treated polyester fabric has the weight loss of 16%, strength loss 16%, and"chemical denudation"phenomenon on the surface of the fiber.
