无纺布袋的机理


来源:本站 作者:jnjs 日期:2016/1/5 18:07:41 浏览次数:100

无纺布袋的原材料是聚丙烯,而塑料袋的原材料是聚乙烯,两种物质虽然名字相似,但在化学结构上却相差甚远。聚乙烯的化学分子结构具有相当强的稳定性,极难降解,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,分子链很容易就可断裂,从而可以有效地降解, 并且在无毒的形态中进入下一步环境循环,一个无纺布袋在90天内就可以彻底分解。
  Non-woven bags of raw material is polypropylene, and the raw material of plastic bags is polyethylene, although two substances similar name, but it is far on the chemical structure. Chemical molecular structure of polyethylene with considerable stability, extremely difficult to degrade, so need to break down over 300 plastic bags; And the chemical structure of polypropylene is not strong, the molecular chain can easily break, which can effectively degrade, and environment in non-toxic form into the next cycle, a non-woven bag can be completely decomposed in 90 days.
  无纺布是一种非织造布,它直接利用高聚物切片、短纤维或长丝通过各种纤网成形方法和固结技术形成的具有柔软、透气和平面结构的新型纤维制品。无纺布袋相较于传统塑料袋的优点:无纺布袋价廉物美,环保实用,应用广泛,有突出的广告位置。适用于各类业务活动及展览展销会,是企事业单位理想的广告促销礼品赠品.
  Non-woven fabric is a kind of nonwoven fabric, it directly using polymer slice, through a variety of short fibers or filament fabric forming method and consolidation technology has soft, breathable and plane structure of new fiber products. Advantages of non-woven bag than traditional plastic bags: non-woven bag of quality and cheap, environmental protection, practical, widely used, there are prominent advertising position. Suitable for all kinds of business activities and exhibition fairs, is the ideal advertising promotional gifts gift enterprises.
  无纺布就是不需要纺织过程而做成似布非布的产品,也叫不织布。因为它是只需将纺织短纤维或者长丝进行定向或随机撑列,形成纤网结构,然后采用机械、热粘或化学等方法加固即可制成。无纺布袋多数是纺粘无纺布制成。
  Non-woven fabric is no need to textile process and make it seems cloth cloth products, also called nonwoven fabric. Because it is simply the textile short fibers or filament for directional or random supporting columns, form a fiber network structure, and then by adopting the method of mechanical, hot glue or chemical reinforcement can be made. Non-woven bags are mostly spun-bonded non-woven fabrics.
