Abstract

The invention relates to a two-bundle screen symmetrical composite yarn, a spinning method and applications thereof. The composite yarn is of 3*2 double-bundle screen composite yarn by conducting 3-shafting compounding to silk frock / chopped fiber / silk screen and 2-shafting symmetrical compounding, has three forms of composite yarns of two screen-wrapped core-spun yarns, two screen-wrapped abut yarns and two 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 following steps: two filaments are split into four bundles by a splitter, wherein two bundles are fed in by means 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 means of bottom supporting or top covering the chopped fiber strands, and the silk bundles and the silk screens are used for clamping chopped fiber strands to be wound into yarns, and then symmetrical twisting and compounding are conducted to form 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 [0001] The invention relates to a double-bundle network symmetrical composite yarn, the spinning method of the composite yarn, the composite yarn and the application of the spinning method, belonging to the filament beam splitting and unfolding pairing of short fiber strands in the technical field of spinning Reinforced protective tow / short fiber / wire mesh composite spinning technology. Background technique [0002] The traditional filament-coated staple fiber composite yarn, because the filaments are bundled, can only partially cover those short and weak fibers, reduce the hairiness of the spun yarn, increase the cohesion between the staple fibers and increase the yarn Strength and improve the wear resistance and quality of yarn. However, due to the relatively thick industrialized filaments, it is difficult to achieve high branching and a high proportion of short fibers in the yarn body without losing the yarn density of the filament / short fiber composite y...
