  无纺布手提袋具有环保购物袋的特性:
  Has the character of environmental protection shopping bag non-woven bag:
  无纺布虽然大部分使用的是聚丙烯,但是和塑料袋的原材料是聚乙烯相比,聚乙烯的化学分子结构具有相当强的稳定性,极难降解。
  Use of polypropylene non-woven fabric while most, but compared with the raw material of plastic bags is polyethylene, polyethylene chemical molecular structure has considerable stability, extremely difficult to degrade.
  所以塑料袋需要300年才可分解完毕,而聚丙烯的化学结构不牢固,分子链很容易断裂,加入光降解剂后,在紫外线的照射下会发生反应,一个无纺布购物袋在阳光的照射下,90天内就可以彻底分解。济南无纺布袋
  So need to break down over 300 plastic bags, and the chemical structure of polypropylene is not strong, the molecular chain is easy to break, after joining the light JiangXieJi, react under ultraviolet light, a non-woven shopping bag in the sunlight, can thoroughly decomposed in 90 days.
  印刷行业的专家也表示,如今在无纺布生产过程中,厂商都采取在聚丙烯中加入光降解剂和光降解助剂的做法。
  Printing industry experts said, now in the process of non-woven fabric production, manufacturers have to take into polypropylene JiangXieJi light and light degradation of additives.
  这样,无纺布在紫外线的照射下,光降解剂就会发生作用,将聚丙烯的分子链条断裂,变成小分子,而光降解助剂又可以阻止这些小分子重新聚集成大分子。
  Such, non-woven fabrics under ultraviolet light, light JiangXieJi occurs, the polypropylene molecular chain rupture, into small molecules, and photodegradation additives can prevent these small molecule regrouped into large molecules.
  所以,在光照条件下,市民所使用的无纺布袋子是完全可以降解的,不会造成环境的污染,虽然无纺布由于在阳光下自然分解导致在回收方面不如塑料袋,但是由于其可以循环使用,所以无纺布手提袋不失为一种环保的选择。
  So, under the condition of light, people can use the non-woven bag is completely degradable, not cause environmental pollution, although non-woven due to natural decomposition in the sun than in terms of recycling plastic bags, but because of its can be recycled, so the non-woven bag can yet be regarded as a kind of environmental-friendly choice.
