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。
Non woven fabric is a kind of nonwovens, which directly uses polymer chips, short fibers or filaments to form a new type of fiber products with soft, breathable and plane structure through various web forming methods and consolidation technology.
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.
Compared with traditional plastic bags, non-woven bags have the following advantages: low price, good quality, environmental protection, wide application and prominent advertising position. It is suitable for all kinds of business activities, exhibitions and sales fairs

无纺布袋厂家的原材料是聚丙烯,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。
Polypropylene is the raw material of non-woven bag manufacturers, while polyethylene is the raw material of plastic bags. Although the names of the two substances are similar, their chemical structures are quite different. The chemical molecular structure of polyethylene is very stable and difficult to degrade, so it takes 300 years for the plastic bag to decompose completely; while the chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, so it can be effectively degraded, and the next environmental cycle can be carried out in the non-toxic form, and a non-woven bag can be completely decomposed within 90 days.
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。
