A kind of high strength vinylon blended yarn
Technical field
The utility model relates to the weaving face fabric technical field, particularly relates to the high strength vinylon blended yarn that a kind of intensity is high, ABRASION RESISTANCE is good.
Background technology
(vinal PVA) not only possesses the characteristics such as acid and alkali-resistance, anticorrosion, wear-resisting, intensity is large, modulus is high, resistance to impact is good to polyvinyl alcohol fibre, and it is heat-resisting, cold-resistant, chemicals-resistant corrosive nature etc. all is better than other synthetic fiber and natural fabric; Next polyvinyl good hydrophilic property, hygroscopicity is higher than other synthetic fiber, it and cotton water absorbing properties approach, have the textile process of being easy to and do not need the advantages such as special installation, polyvinyl also has aboundresources, at home the preferably advantage of equipment Foundations and production capacity is arranged in addition, therefore, polyvinyl once was widely used in garment industry.But polyvinyl also has, and dyeability is poor, color and luster is not bright-coloured, elasticity, hot water resistance are poor, the shortcoming of poor dimensional stability etc., causes polyvinyl to withdraw from gradually garment industry and turn to the industrial fields such as industrial or agricultural, fishery in 20 century 70 later stages.Polyvinyl alcohol fibre is used to substitute asbestos and glass fibre mostly as the fortifying fibre of concrete reinforced material, heat-resisting friction material, tire cord, conveyer belt, high-pressure fire hose, sewing thread, rope and plastics, rubber etc.In recent years, the exploitation of high-strength and high-modulus polyvinyl alcohol fibre was so that polyvinyl alcohol fibre had had the possibility of using at garment industry.On present existing polyvinyl equipment, do not need how many investments, transform a little, just can produce the high-strength and high-modulus polyvinyl, therefore, the high-strength and high-modulus polyvinyl has had the higher ratio of performance to price.Because the heat resistance of polyvinyl far surpasses terylene, so the practical value of high strength vinylon fiber is better than high-strength polyester fiber.Open day be that the patent document that December 14, publication number in 2011 are CN202072842U discloses a kind of polyester cotton blended yarns, relate to a kind of top layer and be mainly the polyester cotton blended yarns that cotton and sandwich layer is mainly terylene, formed by sandwich layer and top layer, to be that the cotton fiber of 60~80% terylene short fiber and 20~40% is staggered mix arrangement to sandwich layer, and to be that the cotton fiber of 20~40% terylene short fiber and 60~80% is staggered mix arrangement on the top layer.This polyester cotton blended yarn has solved mainly that the Quality Pure Cotton Yarn Production brute force is low, cost is high and the polyester cotton blended yarn of prior art touches the poor problem of skinfeel, the cotton yarn that has remedied prior art is difficult to realize the deficiency of mechanical property and skin sense of touch compatibility, but this polyester cotton blending yarn intensity and ABRASION RESISTANCE are all relatively poor, and the scope of application is very narrow.
The utility model content
The purpose of this utility model be for the blended yarn intensity that solves prior art and wear no resistance, problem that the scope of application is narrow provides the high strength vinylon that a kind of intensity is high, ABRASION RESISTANCE is good blended yarn.
The utility model is to reach the concrete technical scheme that above-mentioned technical purpose adopts to be: a kind of high strength vinylon blended yarn, described high strength vinylon blended yarn is formed by the polyster fibre of weight ratio 45% to 60%, 25% to 35% polyvinyl alcohol fibre and 15% to 25% cotton fiber blending, total amount after three kinds of fiber additions is 100%, and described high strength vinylon fiber is that fibre strength is more than or equal to the polyvinyl alcohol fibre of 6cN/dtex.Polyster fibre of the present utility model, high strength vinylon fiber and cotton fiber mixed yarn are because terylene, polyvinyl and the cotton fiber good characteristic that has possessed simultaneously, eliminated self-defect separately, therefore the fabric made from blended yarn of the present invention has good acid-fast alkali-proof, intensity, heat resistance, elasticity, crease resistance, ABRASION RESISTANCE, hygroscopicity, gas permeability and dyeability, specifically, the adding of polyster fibre makes blended yarn of the present utility model have good acid resistance, elasticity, crease resistance, has overcome that polyvinyl alcohol fibre is not acidproof, poor flexibility, the poor shortcoming of crease resistance; The adding of high strength vinylon fiber makes that blended yarn of the present utility model has that good alkali resistance, intensity are good, light resistance, ABRASION RESISTANCE, hygroscopicity, has overcome the shortcoming that polyster fibre is not alkaline-resisting, hygroscopicity is low, gas permeability is poor; The fabric that the adding of cotton fiber is made blended yarn of the present utility model has good dyeability, has overcome polyster fibre and the poor shortcoming of polyvinyl alcohol fibre dyeability.The use of high strength polyvinyl alcohol fibre, so that high strength vinylon blended yarn of the present utility model has good intensity and ABRASION RESISTANCE, especially as open-air dress such as BDU etc., have very large comparative advantages, it not only can be applied to garment industry, and has the very high ratio of performance to price.
In addition, weight ratio described here, refer to polyster fibre, high strength vinylon fiber and the cotton fiber ratio in resultant yarn, because in textile industry, because different raw materials are in process, its proportion of goods damageds are different, when feeding intake in the ratio of each raw material and the final resultant yarn ratio of each raw material also be distinguishing, raw material ratio behind resultant yarn that loss is large can decrease, therefore the large raw material of loss will improve ratio usually when feeding intake, so just can make final product reach the proportion requirement of design, so weight ratio described in the utility model, be the ratio of each raw material in final resultant yarn, also need consider the loss of different materials in spinning process during actual feeding intake.
As preferably, the high strength vinylon blended yarn is formed by the polyster fibre of weight ratio 48% to 53%, 27% to 33% high strength vinylon fiber and 18% to 23% cotton fiber blending, total amount after three kinds of fiber additions is 100%, and described high strength vinylon fiber is that fibre strength is more than or equal to the polyvinyl alcohol fibre of 6cN/dtex.
As preferably, polyster fibre, high strength vinylon fiber and cotton fiber evenly distribute on the cross section of blended yarn.The even distribution on the cross section of blended yarn of polyster fibre, high strength vinylon fiber and cotton fiber can be given full play to three kinds of fibers advantage separately, and is conducive to offset their self-defect.
The beneficial effects of the utility model are: it effectively solved the blended yarn intensity of prior art and wear no resistance, problem that the scope of application is narrow, high strength vinylon blended yarn intensity of the present utility model is high, ABRASION RESISTANCE good, applied widely, have very high practical value.
