Background technology
Superhigh molecular weight polyethylene fibers is one of synthetic fiber that the intensity of current commercial application is the highest, except high strength and high-modulus, UHMWPE fiber also has that density is low, shock resistance, cut resistant advantage, density only has 0.97g/cm
3lower than most synthetic fiber, its chemical stability, light resistance and lower temperature resistance are all very excellent simultaneously, have that intensity is high, modulus is high, fast light, the advantage such as rub resistance, cut resistant, flex endurant, acid and alkali-resistance, resistance to common organic solvents, and there is cooling feeling, be desirable special type protection articles for use goods raw material.
Therefore purposes is widely had, as being applied to special type protection, navigation, fishery, the fields such as sports goods, product comprises shellproof UD cloth, stab-resistance body armor fabric, anti-cutting gloves, all kinds of rope, fishing net etc., but these products are long filament goods substantially, the goods Application and Development of ultra-high molecular weight polyethylene short fiber yarn is less by contrast, this main and market demand, the factors such as cost are relevant, but from use angle, UHMWPE short fiber yarn series products has obvious advantage, such as the free degree is higher, can be dispersed in various matrix, be suitable for doing composite and strengthen skeleton, its yarn product not easily hooks silk, and there is softness, the features such as sense of touch is good.In recent years, the production capacity expansion of domestic superhigh molecular weight polyethylene fibers is very fast, and manufacturing enterprise's quantity and scale are all in continuous increase, and the demand in speedup ultra-traditional long filament far away market, market competition is comparatively fierce.
Therefore rationally digestion and the important subject using superhigh molecular weight polyethylene fibers to become the task of top priority, give full play to the special performance of superhigh molecular weight polyethylene fibers, by its short fiber and other fiber blends or interweave and develop civil nature product and be undoubtedly the feasible development of a line.Current ultra-high molecular weight polyethylene short fiber is pure to be spun and the spinning technique of blended yarn is existing breaks through, but market has no ultra-high molecular weight polyethylene short fiber and flame-resistant terylene blended yarn makes special protecting clothing fabric, and this kind of fabric can give full play to superhigh molecular weight polyethylene fibers has excellent anti-cutting performance, the performances such as extremely strong corrosion resistance and unique cooling feeling, in addition the better fire resistance of flame-resistant terylene is played, desirable physical mechanical performance and good dyeability, achieve and have complementary functions and superpose, thus become a kind of high-grade special protective garment fabric, the blank of this series products on market can be filled up, and be widely used in chemical industry, mine, the making of the special protecting clothing of the industry production personnel such as colliery.
Summary of the invention
Goal of the invention: in order to solve existing special protecting clothing fabric technology content deficiency and lack comfortableness, the invention provides a kind of ultra-high molecular weight polyethylene short fiber and flame-resistant terylene blended yarn as raw material, adopt woven production method to prepare superpower flame retardant special protective garment fabric, have that cloth cover is plain, quality is pliable and tough, high-strength wearable, corrosion-resistant fire-retardant and ventilative nice and cool.This invention can give full play to the excellent properties of superhigh molecular weight polyethylene fibers uniqueness, as strengthened its anti-stab anti-cutting performance, can strengthen the use amount of the ultra-high molecular weight polyethylene staple fibre in blended yarn, to expand its scope of application and Application Areas.
Technical scheme: a kind of preparation method of superpower flame retardant special protective garment fabric, described superpower flame retardant special protective garment fabric adopts the yarn of ultra-high molecular weight polyethylene staple fibre and flame retardant polyester fiber blending as raw material, woven production method is adopted to be prepared from, specific as follows: to adopt ultra-high molecular weight polyethylene staple fibre and flame retardant polyester fiber blended yarn through pooling capital and being twisted strand through weft yarn, make beam of a loom through section warping again on Rapier looms, produce superpower flame retardant special protective garment fabric grey cloth, after lower woven fabric arranges, then process of dyeing obtains finished product;
