Abstract

The invention relates to a lower support type cored enhanced three-axis composite yarn, a spinning method and application thereof. The composite yarn is of a three-layer structure and formed by enhancing through taking a bunch of long filaments as a core, cladding short fiber yarns and wrapping at the outmost layer through filament screen. The spinning method comprises the following steps of: feeding a bunch of long filaments into a lower support type yarn spreader so as to uniformly spread the long filaments into a lower support filament screen of which the width is more than or equal to that of the short fiber yarns; feeding another bunch of long filaments from upper part along the middle line of the short fiber yarns; feeding the short fiber yarns into a front roller jaw between a lower support filament screen and upper fed filament bunches, and forming core-enhanced, filament-screen-wrapped three-axis composite spun yarns under the twisting effect. The method provided by the invention is suitable for spinning protectively-enhanced, soft, smooth and high-count composite yarns from ultrashort, easily-flaky and easily-flying fibers and shorter and weaker recycled fibers. The yarns can be used for weaving into textiles and high-grade fine fabrics with clear texture, good luster, stable structure, abrasion resistance, high strength, anti-fluffing anti-pilling property and capability of preventing dropping chips.

Description

technical field [0001] The invention relates to a composite yarn with extended filament protection and core-spun reinforcement, a spinning method and application of the composite yarn. Background technique [0002] Composite yarns are divided into staple fiber composite yarns, filament composite yarns and staple / filament composite yarns, among which staple / filament composite yarns are further divided into core-spun yarns, wrapping yarns, ply yarns, etc. The production methods of short fiber / filament composite yarn include ring spinning, air-jet spinning, electrospinning, hollow spindle spinning, rotor spinning, etc., and ring spinning is the most widely used. There are two ways to feed the filament yarn, one is that the filament yarn is directly fed into the twisting area of ​​the staple fiber, and then directly wound and twisted with the staple fiber; the other is that the filament yarn is short under high tension. The fibers are wound onto a filament yarn to form a coresp...
