Detailed Description

The polypropylene fiber is great for acid proof, alkali proof, and great anti- abrasion (second only to the polyamide fiber). Polypropylene staple fiber is short, and hairy after spun. While Polypropylene fiber is long, and the filament yarn is smooth, so the fabric make of filament yarn has larger tenacity than the fabric made of staple yarn, as well as greater air permeability. Filter fabric made of staple yarn has hair on the surface, so it is better than filter fabric made of filament yarn for dust collection and pressure filtration. While the fabric made of filament yarn has smooth surface and high air permeability , so it is suitable for liquid filtration. We have successfully equipped many filter presses in various industries with our polypropylene filter fabric. The force of the polyamide fiber is the strongest among all the fibers; the tenacity is 4-5.3CNdtex, and the elongation is 18%-45%. The recovering ability is above 90% when elongation is around 10%. Its anti-abrasion is 10 times of the cotton fiber, and 50 times of viscose fiber. Wearability occupies the first place in various kinds of fibers, so it is an ideal material for rubber automobile tire making. Polyamide fiber has great alkali proof, but can only stand for weak acid. Under the condition of Nao (10% ), 95, 16 hours, the tenacity almost lose nothing. But polyamide fiber can not stand for sunlight. It will easily become fragile and change color, so polyamide fabric should not be exposed under the sunlight for a long time. It is used in the ceramics factory, the pharmaceutical factory, foodstuff industry, and metallurgy, etc., and it is more suitable for the rubber trade. But polyamide-66 should not be used in pharmacy and foodstuff industry because its poison, otherwise it will do harm to human health. We should select polyamide-6 fibers for such industry as pharmacy, foodstuff, etc. Our polyamide fabric is made of Polyamide-6.
