Abstract
The invention relates to double-bundle screen asymmetric composite yarn, a composite spinning method and applications. The composite yarn is of 3*2 double-bundle screen composite yarn by carrying out 2-shafting symmetrical compounding to silk frock/chopped fiber/silk screen 3-shafting symmetrical screen-wrapped core-spun yarns, silk frock/chopped fiber/silk screen 3-shafting symmetrical screen-wrapped abut yarns, or silk frock/chopped fiber/silk screen 3-shafting symmetrical screen-wrapped fascinated yarns, and can be used for weaving fabric and fine high-grade fabric, which have clear textures, are soft and wear-resistant, high in strength and pilling-proof and attractive and comfortable. The spinning method for realizing the composite yarn comprises the steps of splitting two filaments into four bundles by a splitter, wherein two bundles are fed in with equal to unequal tension by a manner of being centered, abutted, or left from chopped fiber strands; the other two bundles are spread by a filament spreader into silk screens, and are fed in by a manner of bottom supporting, top covering or leaving the chopped fiber strands; clamping the chopped fiber strands in pairs to be wound into yarns, and then symmetrically compounding and twisting into yarns. The method is applicable to spinning of protective type soft, smooth and high-count composite yarns for ultrashort fibers which are easy to fall crumbs and easy to fly, as well as shorter and weaker reclaimed fibers.
Description
Technical field
The present invention relates to a kind of Double-bundle screen asymmetric composite, the spinning method of this composite yarn, the application of this composite yarn and this spinning method, belong in spinning field and wrap up in tow enhancing silk screen 3 × 2 asymmetric compound spinning techniques twining protection.
Background technology
Along with renewable fibre resources and reclaimed fibre carry out textile process as the raw material of textiles, the feature due to this two types of fibers resource is that length is short, powerful impaired and powerful low, and the product filoplume be processed into is many, wear no resistance, and quality is low.Thus cause this class fiber partially short, on the weak side not to be fully utilized.This patent provides the composite yarn of the coated short fiber of long filament can make up the deficiency of this respect, improves the utilization rate of staple fibre.First must solve endless tow and be separated into one filament, become the prerequisite of filament and short staple composite spinning.But at present about endless tow compartition is the patent report of one filament, patent continuous tow dispersing device (patent publication No. CN1811025A) as strong in horse mainly relies on air pressure to be used for sub-wire process, receiving/releasing volume Apparatus and method for (patent publication No. CN1884026A) that tow is decomposed into parallel filaments by the patent of Yu Mingwei is made up of point reed device and tenslator, control tension force by tenslator, by the centrifugation of sub-wire reed, tow is resolved into parallel filaments.
Therefore, realize the available protecting of short, weak fiber at present, the preferred embodiment of refinement and the processing of high-quality composite spinning is exactly solve the refinement problem of long filament.Current method is by the number of fiber reduced in endless tow or one filament is attenuated.The former easily causes fiber beam splitting to damage because of speed reduction influence spinning output with because spinning speed is high, and not only output significantly declines the latter, increase of breaking end, and is the specialized spining technology that difficulty is higher.Relevant long filament launches technology into the net, more rarely seen.Continuous tow dispersing device (patent publication No. CN1811025A) as strong in horse, primarily of air separator and carding composition, adopts air separation long filament separately, is obviously unsuitable for the spinning of staple fibre yarn.Tow is decomposed into the arrangement of receiving/releasing volume Apparatus and method for (patent publication No. CN1884026A) for large width of parallel filaments by the patent of Yu Mingwei, not only all not identical in mechanism, principle and method with patent of the present invention, and cannot short staple spinning be used for.What the patent bundle fiber of Joseph Lee Lifke divided is made up of from method and apparatus (METHOD AND APPARATUS FOR SPEREADINGFIBER BUNDLES) (patent publication No. US6049956) several dispersion drum, by the angle changing dispersion drum two ends disk, fibre bundle is scatter, the not only bright big patent of problem congruence, and be that main equipment and mechanical part are many.
Therefore be necessary to provide a kind of to improve spinning count with long filament beam splitting, be launched into long filament the specialized technology that net carries out protection spinning, the height of the available protecting and high-quality spinning processing and conventional fibre that realize short, weak fiber props up the spinning that even superelevation is propped up.
Summary of the invention
An object of the present invention is to provide and a kind ofly can reach that asymmetrical tow strengthens, silk screen wraps up in the protection spinning twining staple fibre yarn, be applicable to ultrashort, easily to fall bits, easily flying cotton fibers and partially short, on the weak side reclaimed fibre protection, flexible smooth, a high composite yarn.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 above-mentioned spinning method.
