环保载体的制备及在毛/涤一浴染色中的应用

Environmental friendly carrier preparation and its application in one-bath dyeing of wool/polyester fabric

为降低涤纶的染色温度,实现毛/涤混纺织物一浴法染色,制备具有良好稳定性的环保无味载体乳液,测试载体对涤纶玻璃化转变温度的影响,探讨染色温度、载体用量对涤纶染色效果的影响,以及毛/涤一浴染色后解决分散染料沾染羊毛的方法。结果表明,载体对涤纶有明显的增塑作用,使用自制的载体乳液可以于98℃染涤纶,载体的最佳用量为5%(owf);毛/涤一浴染色后,用含保险粉0.6 g/L,碳酸钠1.0 g/L,阴离子表面活性剂AES1.0 g/L的还原液,采用1∶50的浴比于75℃还原清洗10 min,有效解决了分散染料沾染羊毛的问题。

In order to decrease polyester dyeing temperature,and realize one-bath dyeing of wool,polyester blended fabric,environmental friendly inodorous carrier emulsion with good stability was preparation,the effects of carrier on polyester glass transition temperature,dyeing temperature and carrier amount on polyester dyeing performance were investigated,and solving method of disperse dye staining wool after one-bath dyeing of wool and polyester was discussed.The results showed that carrier had obvious plasticizing effect,polyester can be dyed at 98 ℃ by using the carrier,the optimum carrier amount was 5%（owf）.After one-bath dyeing of wool and polyester,reduction cleaning at 75 ℃ for 10 min with bath ratio1∶50 by using solution containing sodium hydrosulfite 0.6 g/L,sodium carbonate 1.0 g/L,and anionic surfactant AES 1.0 g/L,which could solve the problem of disperse dye staining wool.
