无纺布材料特点
1.质轻:以聚丙烯树脂为主要生产原料,比重仅0.9,只有棉花的五分之三,具蓬松性,手感好。
1. Light weight: polypropylene resin as the main raw material, the proportion is only 0.9, only three fifths of cotton, fluffy, good feel.
2.柔软:由细纤维组成(2-3D)轻点状热熔粘结成型。成品柔软度适中,具舒适感。
2. Softness: It is made up of fine fibers (2-3D) by light point hot melt bonding. The finished product has moderate softness and comfort.
3.拨水、透气:聚丙烯切片不吸水,含水率零,成品拨水性佳,由100%纤维组成具多孔性,透气性佳,易保持布面干爽、易洗涤。
3. Drainage and breathability: Polypropylene chips do not absorb water, water content is zero, water transfer of finished products is good, composed of 100% fibers with porous, good air permeability, easy to keep the cloth surface dry and easy to wash.
4.无毒、无刺激性:产品采用符合FDA食品级原料生产,不含其他化学成分,性能稳定,无毒、无异味,不刺激皮肤。
4. Non-toxic and non-irritating: The product is made from food-grade raw materials conforming to FDA, without other chemical components, and has stable performance, non-toxic, odorless and non-irritating skin.
5.抗菌、抗化学药剂:聚丙烯属化学钝性物质,不虫蛀,并能隔离存在液体内细菌及虫类的侵蚀;抗菌、碱腐蚀、成品不因侵蚀而影响强度。
5. Antibacterial and anti-chemical agents: polypropylene is a chemical passive substance, which does not moth, and can isolate bacteria and insects in the liquid. Antibacterial, alkali corrosion and finished products do not affect the strength due to erosion.
6.抗菌性。制品具拔水性,不发霉,并能隔离存在液体内细菌及虫类的侵蚀,不霉蛀。
6. Antimicrobial activity. The product is water-extractable, mildew-free, and can isolate the presence of bacteria and worms in the liquid, not mildew and moth.
7.物性佳。由聚丙烯纺丝直接铺成网热粘结而成,制品强度较一般短纤产品为佳,强度无方向性,纵横向强度相近。
7. Good physical properties. The product is made of polypropylene spinning and directly laid into a net by thermal bonding. The strength of the product is better than that of ordinary staple fibers. The strength has no directionality and the longitudinal and transverse strength are similar.
8.在环保方面,目前使用的大多数无纺布的原材料是聚丙烯,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,一个无纺布购物袋在90天内就可以彻底分解。而且无纺布购物袋可重复使用10次以上,废弃后对环境的污染度也只有塑料袋的10%。
8. In terms of environmental protection, polypropylene is the raw material of most non-woven fabrics, 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 and molecular structure of polyethylene is quite stable and very difficult to degrade, so it takes 300 years for plastic bags to decompose; while the chemical structure of polypropylene is not strong, and the molecular chain can easily break down, which can effectively degrade, and enter the next environmental cycle in the non-toxic form, a non-woven shopping bag can be completely decomposed in 90 days. Moreover, the non-woven shopping bags can be reused more than 10 times, and the environmental pollution of the discarded bags is only 10% of that of the plastic bags.
