Category:Industry information  Date:2013-03-18  Views:1427
Non-woven production is mainly of polypropylene fiber ( PP ), polyester ( PET ). In addition, there are nylon ( PA ), viscose fiber, acrylic fiber, polyethylene ( HDPE ), polyvinyl chloride ( PVC ). According to the application requirements, non-woven fabric as disposable and durable two categories.
According to the production process is divided into:
1: spunlaced nonwoven spunlace process is high pressure micro water jet to one or more layers of fiber network, the fibers are intertwined, so that the fiber network to be reinforced and have a certain strength.
2 non-woven fabric: thermal bonded nonwoven refers to adding fibrous or powder hot melt adhesive reinforcement material in the web, the web through cooling heating and melting reinforcement into cloth.
3 pulp airlaid nonwovens: airlaid nonwoven can also be called the dust-free paper, pulp non-woven fabric. It is the use of airlaid pulp fiber board technology will be opening into a single fiber, and then use the airflow method makes fiber agglutination in the screen, web reinforcement into cloth.
4 wet nonwoven fiber raw material: non-woven fabric is arranged in the water medium opening into a single fiber, and the different fiber raw material mixing, made of fiber slurry, slurry is transported to the web formation mechanism, fiber in the wet web reinforcement into cloth.
5 spunbonded nonwoven fabric: spunbonded nonwoven fabric is in the polymer has been squeezed out, stretch and formation of continuous filament, filament laying into the net, web after bonding, thermal bonding, chemical adhesive or mechanical reinforcement method, make the web into a non-woven fabric.
6 melt-blown non-woven fabric: process of melt-blown non-woven fabric: polymer feed - melt extrusion, fiber formation - fiber cooling - Net - reinforcement into cloth.
7: non-woven needle-punched nonwoven fabric is a dry non-woven, non-woven needle puncture needle is the use function, the fluffy, web reinforcement into cloth.
8 stitch bond: stitch bond is a dry non-woven, stitch-bonded is on the web, yarn, non-woven materials using warp coil structure (such as plastic sheet, plastic thin metal foils ) or their combination for reinforcement, the non-woven fabrics.
9 hydrophilic nonwoven fabric : mainly used in medical and health materials production, to get a better feel and do not scratch the skin. Like sanitary napkins, sanitary pad is the use of a hydrophilic nonwoven fabric hydrophilic function.
