One-bath Dyeing of Polyester/Wool Blend with Disperse Dyes

The role of auxiliary LAB as vehicle in dyeing polyester/ wool blends with disperse dyes is described. Dye exhaustion and bonding on polyester/wool samples are studied under different experimental conditions - the LAB amount, the temperature and pH value - to achieve optimum conditions.

对文题的研究表明,染料阳离子与纤维内部的阴离子经离子交换而结合。染色是放热及熵减小过程。苯甲醇的存在,提高了染色饱和值和染色速度;降低了染色亲合力、染色热及染色熵;消除了环染,其效果随染浴(或纤维)内苯甲醇浓度的升高而加强。用红外光谱法及X-射线衍射法测定了经苯甲醇水溶液处理过的聚合物的结晶性能;用差式扫描量热法、拉伸试验和动态粘弹谱等方法测定了该聚合物的熔融及力学性能。结果表明,苯甲醇渗入了聚合物(纤维)内部,并减弱其非晶区的分子间的相互作用,但不破坏结晶区,同时导致纤维溶胀,链段淌动性加强,因而促进了染色。
