基于ATRP接枝HEMA进行黏胶织物抗皱整理的研究

Research of anti-wrinkle treatment for viscose fabrics based on ATRP grafted by HEMA

为探讨黏胶织物基于原子转移自由基聚合反应(ATRP)接枝甲基丙烯酸羟乙酯(HEMA)进行抗皱整理的可行性,黏胶织物经2-溴异丁酰溴修饰后使其表面产生引发基团,在催化作用下引发ATRP接枝HEMA进行抗皱功能整理,测试黏胶织物抗皱性能的变化,并利用相关测试方法对整理后黏胶纤维的结构变化进行分析。测试结果表明:黏胶织物基于ATRP接枝HEMA进行抗皱整理后,其抗皱性能得到显著提高,验证了该抗皱整理工艺的可行性。由红外ATR吸收光谱、X-射线衍射谱和冷场扫描电镜图像可知,HEMA被成功接枝到黏胶纤维表面,接枝前后的黏胶纤维的大分子结构基本没有发生变化,且生成的聚合物在黏胶纤维表面的分布相对均匀。

In order to test the feasibility of anti-wrinkle treatment for viscose fabric based on atom transfer radical polymerization（ATRP）grafted by hydroxyethyl methacrylate（HEMA）,viscose fabrics were set as the experimental materials,and after they were modified by 2-bromo-isobutyryl bromide,the initiators were generated on surface,ATRP reaction for grafting HEMA for anti-wrinkle finishing was catalyed.Changes in anti-wrinkle properties were tested and the means of structural changes related to the finishing on viscose fibers were analyzed.The results showed that viscose fabric grafted HEMA-based anti-wrinkle finishing ATRP,its anti-wrinkle performance has been significantly improved,and the feasibility of the anti-wrinkle approach was verified.Meanwhile,it was seen by the infrared absorption spectrum from ATR,scanning electron microscopy and X-ray diffraction image that HEMA ensure was successfully grafted onto the fiber surface,the resulting polymer in a relatively uniform distribution on the surface of viscose fibers,and the macromolecular structure of the fibers before and after grafting was basicly no change.
