nonwoven fabrics manufacturersThe exact name should be non-woven fabric, or call non-woven. Because it is a do not need to fabric formed by weaving, spinning, just short of textile fibers or filaments, or randomly oriented support columns to form a fiber web structure, and mechanical, thermal or chemical methods such as reinforcement adhesive made. Non-woven textile fabric breaks through the traditional theory, and have short process, production speed, high output, low cost, versatile, multi-source characteristics of raw materials, which is the direct use of polymer chips, staple fiber or filament will fiber through the air or mechanical into the net, and then through the spunlace, acupuncture, or hot-rolled reinforcement, non woven SMS fabricafter finishing the final form of non-woven fabric. With soft, breathable and planar structure of the new fiber products, the advantage does not produce fiber dust, tough, durable, silky soft, but also the feeling of cotton, and cotton compared to non-woven bag easy to shape and are cheap.
In environmental protection, disposable face masksthe majority of currently used non-woven raw material is polypropylene, and plastic raw material is polyethylene, car coveralthough the names of two substances similar in chemical structure but are very different. Molecular structure of polyethylene has a very strong chemical stability, extremely difficult to degrade, it needs 300 years to decompose plastic bags end; and the chemical structure of solid polypropylene molecular chain can easily be broken, which can effectively degrade , surgical gown and non-toxic form in the environment into the next cycle, a non-woven shopping bags in 90 days can be completely decomposed. And nonwoven shopping bags can be reused 10 times more waste to environment pollution, only 10 percent of plastic bags
adult diaperBecause of its exterior shape of pearls, also known as pearl canvas.
Non-woven advantages and disadvantages:
Non-woven fabrics have many advantages: 1) ventilation 2) filter of 3) insulation of 4) water absorption 5) waterproof 6) scalability 7) does not disheveled 8) feel good, soft 9) light 10) are flexible, Recovery of 11) did not directional fabric 12) compared with the production of textile fabrics and high production speed of 13) low price, mass production and so on can be.
Disadvantages are: 1) the strength and durability of textile fabrics less than 2) can not be as clean as other fabrics 3) fibers arranged in a certain direction, so easy to crack from the right angle so. Therefore, the recent improvements in production methods on the prevention of major improvements to the division. |
