Description
技术领域:
本发明涉及无纺布生产技术领域,具体涉及一种清香环保无纺布的制备方法。
背景技术:
随着塑料工业的蓬勃发展,废旧塑料薄膜垃圾带来的环境污染也日趋严重,白色污染成为全球瞩目的环境问题。因此,人们必须要加大力度去开发生物可降解的塑料薄膜,治理塑料废弃物对环境所带来污染问题。
无纺布占据了薄膜一部分市场,强度较薄膜强,但是寿命短,阳光直射,长时间无纺布即变脆。
淀粉是一种来源丰富、价格低廉的天然高分子材料,也是一种取之不尽用之不竭的可再生资源,它能在多种环境条件下被生物降解,最终降解产物二氧化碳和水可以通过植物的光合作用再循环,不会对环境造成任何污染。然而淀粉分子链上含有大量羟基,容易在分子链内和分子链外形成氢键,因此难溶、难熔,并且耐水性差,一遇水或长期存放在潮湿空气中容易吸收水分,影响其稳定性。
发明内容:
本发明所要解决的技术问题在于提供一种工艺简单、生产成本低且对环境友好的清香环保无纺布的制备方法。
