Non-woven fabric characteristics
Non-woven fabric is a nonwoven fabric, it is the direct use of polymer chips, staple fibres or filaments will fiber through the air or machinery into the net, and then through the water, acupuncture, or hot rolled reinforced, finally after finishing the formation of non woven fabric. New fiber products with soft, breathable and planar structure, has the advantages of no produce lint, tough, durable, soft and silky, but also enhance a material, but also cotton feeling, compared with cotton, non-woven bag is easy, and cheap cost.
Advantage.
1 weight: using PP as main raw materials, the proportion of only 0.9, only 3/5 of cotton, with fluffy, feel good.
2 soft: composed of fine fiber ( 2-3D ) with hot-melt adhesive forming. The finished product of appropriate softness, comfort.
3 water, breathable: PP chips without water absorption, moisture content of zero, the finished water repellency, composed of 100% fibers with porous, good air permeability, easy to maintain, easy to wash and dry cloth.
4 non-toxic, non-irritating: products with FDA food grade raw material production, not including other chemical components, performance is stable, non-toxic, no smell, no stimulation to the skin.
5 antibacterial, anti chemical: polypropylene chemical blunt substance, not moth-eaten, and can exist in isolation liquid bacterial and insect attack; antibacterial, alkali corrosion, erosion and the impact strength of product not because of.
6 antibacterial. Products with pull water, not mildew, and can exist in isolation liquid bacterial and insect attack, no mildew and moth.
7 good. Made of polypropylene spinning laid directly into the net thermal bonding, product strength is generally staple products is preferred, strength and no direction, vertical and horizontal strength.
8 in the aspect of environmental protection, raw materials used at present is most non-woven polypropylene, the plastic raw material is polyethylene, two substances although the names are similar in chemical structure, but it differs very far. The chemical molecular structure of polyethylene with stability is strong, extremely difficult to degrade, so the plastic bags take 300 years before they can complete decomposition; chemical structure of PP molecular chain is not firm, it is easy to fracture, which can effectively degrade, and into the environmental cycle the next step in nontoxic form, a non-woven shopping bags in 90 days can be decomposed completely. And non-woven shopping bag can be used repeatedly for 10 times, the waste on the environment pollution degree is only a plastic bag 10%.
Disadvantages:
1 ) compared with the textile fabric strength and poor durability
2 ) cannot be cleaned like other cloth.
3 ) fiber according to a certain direction, so it is easy to split from the right angle direction etc.. So the recent production process improvement mainly on the improvement on preventing splitting.
