Abstract
The invention relates to a coaxial tow net composite yarn prepared from tows in different numbers, a spinning method and application. The tow net composite yarn is a three-layer tow net composite yarn with tows and silk nets with different filament numbers and staple fiber strands mutually reinforced and wrapped and at least an axis coaxial with the staple fiber strands and can be used for weaving fabrics and fine high-grade fabrics which have clear textures, are soft and wear-resistant, have high strength, are resistant to pilling and are beautiful and comfortable. The spinning method realizing the composite yarn is characterized by adopting a silk spreading and splitting device to split filament tows into two asymmetric silk layers after spreading the filament tows into silk layers, wherein one silk layer goes straight or is led downward and is spread into a silk net by a silk spreading device; the other silk layer descends or ascends and is clustered; and the two silk layers and the staple fiber strands form upper, middle and lower axes to be synchronously fed into a front roller jaw and form the three-axis tow net composite yarn in a twisting triangle area. The method is suitable for spinning the protective, soft, smooth, clean, high-count and ultrafine-count composite yarns with ultrashort fibers liable to flock drop and flying and shorter and weaker recycled fibers.
Description
Technical field
The present invention relates to a kind of distinct root and count the same axial strand net composite yarn of beam splitting; the spinning method of this composite yarn; the application of this composite yarn and this spinning method, belong to the beam splitting of the endless tow distinct root number in ring spinning field and launch after strengthen and wrap up in the protection composite spinning technology that twines outward in short fiber yarn is done.
Background technology
Along with the fast development of textile industry, the noil in textile process process, short, the on the weak side fibrid of fuds fuddled isogonic increase; Reuse textiles gained fiber is compared with fibrillation with in intensity in length, has certain gap; Some new ultrashort, fragile fibers, as kapok, eider down etc., start to be concerned and to utilize.And the spun yarn strength of these fibers partially short, class on the weak side is low, and filoplume is many.So just cause this class fiber partially short, on the weak side not to be fully utilized.
Meanwhile, in the processing of existing long filament for convenience of and high yield, all produce thicker long filament, the line density value of conventional variety is greater than 30D (DENIER).If high-count yarn spun, is more than or equal to the yarn of 80S (public), a threads Shu Benshen will account for the more than 30% of composite yarn quality.Therefore the conventional long filament of two bundles almost will account for the more than 60% of composite yarn quality, more than individual staple fibers yarn just reaches 150S, if two staple fibre yarns are exactly more than 300S, this is even drawing-off resultant yarn almost, because only have several to tens staple fibres.Therefore, select the long filament of low dawn number≤20D, beam splitting is the endless tow below 10D even again, is the necessary of high of spinning or ultra-fine (>=120S) yarn.
The be as the criterion report that has no of individual layer filament layer of relevant endless tow compartition, the patent continuous tow dispersing device (patent publication No. CN1811025A) that close patent is as strong in horse is random dispersion, is not to be divided into accurate individual layer, it is mainly made up of air separator and carding, in air separator, there is hollow cylinder, its upper port has sub-wire chamber, bottom surface, sub-wire chamber is the wire sub-panel that is distributed with some passages, combing groove is housed in carding, this gas separate mode is not suitable for the spinning of staple fibre yarn, because can strengthen the disorder of flyings and yarn.The receiving/releasing volume Apparatus and method for (patent No. publication number CN1884026A) that tow is decomposed into parallel filaments by the patent of Yu Mingwei is made up of point reed device and tenslator, by tenslator control tension force, by the centrifugation of sub-wire reed, tow is resolved into parallel filaments.What the patent bundle fiber of Joseph Lee Lifke divided is made up of several dispersion drums from method and apparatus (METHOD AND APPARATUS FOR SPEREADING FIBER BUNDLES) (patent No.: US6049956), disperse the angle of drum two ends disk that bundle dividing is scattered by change, many, the mechanical concertednesses of the method plant machinery parts require high.
Above-mentioned each correlation technique, one, is all taking the outstanding fiber of spinnability as object, changes the spinning of resultant yarn style and fancy or high Zhi Huawei object, cannot be for spinnability poor or cannot spin spinning of fiber at all; Its two, be unsuitable for the high branching of partially short fiber on the weak side, the composite spinning of superelevation branching even.
Summary of the invention
An object of the present invention is to provide a kind of composite yarn, this composite yarn can with less long filament to partially short, on the weak side, difficulty is spun, even tradition spin fiber-spinnable not low consumption, efficient, anti-flyings, fall the enhancing protection spinning of hair and fluffing.Another object of the present invention is to provide a kind of spinning method of above-mentioned composite yarn.Another object of the present invention is to provide the application of a kind of above-mentioned composite yarn and spinning method.
