Description

一种含竹活性炭粉的可降解环保无纺粘合衬及其制备方法
【技术领域】
本发明涉及粘合衬的技术领域，特别涉及一种含竹活性炭粉的可降解环保无纺粘合衬及其制备方法。
【背景技术】
现代服装讲求在穿着风格上体现舒适、柔软、轻盈和随意有弹性。粘合衬作为“服装的骨架”，是服装不可忽缺的辅料，粘合衬是一种涂有热熔胶的衬里，是布艺制作经常用到的辅料之一。粘合衬经过加温熨压附着在布料的背面，“以粘代缝”大大简化生产工艺，且适用面广，其与面料的合理配合，不仅能充分体现服装设计师的设计思想，而且能够达到良好的服用效果。
但是随着高分子材料的快速发展，在肯定其优点的同时也发现了它的不足，即大部分人工合成的高分子材料在自然界中难以降解，不可降解的高分子材料造成了对环境的白色污染。而一些化学纤维的废弃物难以降解，已成为新的污染源。目前主要采用再生法、燃烧法和降解法来解决这个问题。且目前的布料的功能性较为单一，抗菌、保健性效果低，为了使粘合衬具有抗菌、保健性效果，同时还能降解，具有环保性，有必要提出一种含竹活性炭粉的可降解环保无纺粘合衬及其制备方法。
【发明内容】
本发明的目的在于克服上述现有技术的不足，提供一种含竹活性炭粉的可降解环保无纺粘合衬及其制备方法，其旨在解决现有技术中布料的功能性较为单一，抗菌、保健性效果低，难以降解，环保性较差的技术问题。

步骤三、制备基布：将皮芯复合纤维网层与抗菌吸湿层通过热轧复合，使皮芯复合纤维网层与抗菌吸湿层上的纤维相互穿插，得到基布；
步骤四、固着竹活性炭粉：按一定的质量比选取蒸馏水和竹活性炭粉，并加入适量的分散剂，初步搅拌后置于超声波振荡器3～6min，充分混合至无沉淀后，加入适量粘合剂，再次置于超声波振荡器2～4min，得到竹活性炭粉喷涂液，然后采用喷涂法垂直喷涂于基布上，并阴凉处晾干；
步骤五、涂热熔胶：采用PES作为底浆，PA作为面粉，通过双点涂层法在靠近皮芯复合纤维网层的基布一面涂热熔胶层，得到含竹活性炭粉的可降解环保无纺粘合衬。
作为优选，所述的步骤二中密封搅拌时间为3～4天。
