Embodiment 1

[0042] Embodiment 1: Spinning recycled cotton / viscose filament composite yarn

[0043] Using the re-expansion and clustering composite filament spreader for asymmetric spreading and splitting of the present invention, the viscose filament bundle is split and spread into tow and silk net according to the above-mentioned splitting and spreading method, and then The front roller nip is twisted and compounded with recycled cotton fiber strands to form a smooth reinforced composite yarn. The specific process parameters are shown in the table below. Since the core / network splitting mass ratio is 1:1, the theoretical occupancy of the surface silk screen is 1 / 2 of the composite ratio, that is, 14.405%. The content of the measured surface viscose filament is 13.0%. can be effectively displayed. 13.0% of the viscose filaments spun into split yarns and wrapping the smooth composite yarns of noil staple fibers, the yarn hairiness index, twist angle, breaking strength, elongation at break...

Embodiment 2

[0044] Embodiment 2: spinning kapok / polyester filament composite yarn

[0045] Using the re-spreading and clustering composite spreader for asymmetric spreading and splitting of the present invention, the polyester filament bundles are split and spread into tows and screens according to the above-mentioned splitting and spreading method, and then The kapok is twisted and composited at the nip of the roller to form a smooth reinforced composite yarn. The specific process parameters are shown in the table below. Since the core / network splitting mass ratio is 3:7, the theoretical occupancy of the surface screen mesh is 7 / 10 of the composite ratio, that is, 18.98%. The measured surface polyester filament content is 17.73%, and the characteristics of kapok fiber can be displayed. And it can effectively prevent chipping and reduce hairiness. The spun polyester filament split yarn is a smooth composite yarn wrapped with kapok fiber strands. The hairiness index, twist angle, breaking...

Embodiment 3

[0046] Embodiment 3: Reuse cashmere / silk composite yarn

[0047] Using the re-expansion and clustering composite silk spreader for asymmetric spreading and splitting of the present invention, the silk is split and spread into tows and silk nets according to the above-mentioned splitting and spreading method, and then the front roller nips Twisting and compounding with recycled cashmere fiber strands to form a smooth reinforced composite yarn. The specific process parameters are shown in the table below. Since the core / network splitting mass ratio is 9:1, the theoretical occupancy of the surface silk mesh is 1 / 10 of the composite ratio, that is, 1.688%. The measured surface silk content is 0.54%, and the characteristics of cashmere fibers can be fully displayed. , almost no filaments, and can effectively reduce hairiness. The spun silk split yarn is wrapped with cashmere staple fiber and is wrapped with smooth and clean composite yarn. The hairiness index, twist angle, breakin...

Abstract

The invention relates to a composite filament spreader capable of re-spreading and bundling for asymmetric filament spreading and bunch division, a method and application of the composite filament spreader. The composite filament spreader comprises a yarn guiding rod, a splitter, a yarn guiding hook, a filament spreader and the like, wherein the yarn guiding hook is used for guiding the uplink and the downlink of long filaments; and the composite filament spreader is arranged on a ring spinning frame through a fixed frame. The method for re-spreading and bundling for asymmetric filament spreading and bunch division comprises the following steps of: flattening the long filaments through the yarn guiding rod, and asymmetrically spreading and splitting the long filaments through the splitter; and leading the long filaments to a centering line through an uplink yarn guiding hook, feeding the long filaments closely to a front roller, centering and feeding the long filaments into the filament spreader through a downlink yarn guiding hook, spreading the long filaments into a filament screen, and outputting the filament screen closely to a lower roller. The composite filament spreader can be applied to spinning enhanced protective type, soft, smooth, high-count and ultrathin composite yarns from ultrashort, easily-flaky and easily-flying fibers and shorter and weaker recycled fibers.

Description

technical field [0001] The invention relates to a filament bundle splitting and spreading protection composite spinning device in the field of ring spinning, a composite spinning method using the device and an application of the device. Background technique [0002] With the rapid development of the textile industry, the application of filaments is becoming more and more extensive, especially in the utilization of short fibers. In the textile processing process, short and weak fibers such as noil and noil increase; the fibers obtained from recycled textiles also have a certain gap in length and strength compared with the original fibers; these short and weak fibers The fiber cannot be spun or the spun yarn has low strength and more hairiness. As a result, this type of short and weak fibers cannot be fully utilized. However, the composite yarn of filaments covering staple fibers can make up for this deficiency and improve the utilization rate of staple fibers. [0003] It ...
