涤纶剥色新工艺的研究
摘要
研究得出了适用于涤纶织物上分散染料的一种新型剥色剥色工艺,通过两个工艺步骤实现了对涤纶织物上分散染料的剥除。先选择适当的溶胀试剂对染色后的涤纶织物进行溶胀,在120℃条件下溶胀20分钟,降低了涤纶纤维分子链间的紧密度,空间取向度也随之降低,从而减弱了分散染料分子和涤纶纤维分子间的结合力;然后选用适当的剥色试剂对涤纶剥色,在110℃条件下剥色30分钟,达到了较理想的剥色效果,溶胀和剥色过程对织物的影响不大,剥色后涤纶织物K/S值下降百分率可以达到80%～90%,相对于传统剥色工艺剥色后织物K/S值下降百分率明显提高,损失较小,与涤纶常用剥色方法剥色后织物强力损失百分率相差不大。用新型剥色剥色工艺对涤纶织物剥色后,溶胀试剂和剥色试剂可以回收利用,并且染料也能回收利用,因此减小了对环境污染。通过实验得出:影响涤纶新型剥色工艺剥色效果的因素主要有溶胀试剂、溶胀时间、溶胀温度、剥色试剂以及剥色温度、时间等。同时对剥色后的涤纶织物再次用分散染料染色或者回收的分散染料染色亦能取得较好的染色效果。并且发现喹啉酞酮类分散染料染色的涤纶织物相对与偶氮类、蒽醌类分散染料染色的织物溶胀效果和剥色效果较差,混拼染料染色的涤纶织物溶胀效果和剥色效果相对较好,这与分散染料的分子结构特征以及染料分子和涤纶纤维分子之间结合力的强弱有关。
This paper has studied a new stripping method used in removing the disperse dyes of the polyester fabric, and included the optimum technology used in removing redients the disperse dyes of the polyester. There are two steps in process of stripping on polyester, First, chose the appropriate swelling agent to decrease the binding of disperse dyes molecular and polyester fabric, swell the polyester fabric 20 minutes at 120℃, and then use the stripping agent to remove the disperse dyes of the polyester fabrics for 30minutes at 110℃, stripping effects are satisfactory, the K/S value is decrease about 80%～90%, and strong trauma of polyester fabric is during 9%～15% after stripping process. Swelling agent and stripping agent could recycled and used for stripping again, disperse dyes and polyester fabric could recycled as well, the recycled swelling agent and stripping agent could used for stripping again, the recycled polyester fabric and disperse dyes could used for dyeing, so environment pollution that caused by the stripping is reduced obviously. The experiments analysis demonstrates that the factors of the stripping effect are the swelling agent, the time and the temperature of the fabrics swelling and stripping, The effects will be strengthened with the time and the temperature of swelling and stripping process, Then the stripping effects will be stable. Through the experiments find that compare with other disperse dyes, The polyester fabric that dyed with disperse yellow 3GSL swelling effect and stripping effect is worse, while the swelling and stripping effect of disperse gray SBL and disperse deep brown S-2RFL are better, this mainly related to the structure characteristic of disperse dyes and the strength during disperse dyes molecular with polyester fiber molecular.
