Embodiment 1

[0038] Embodiment 1: Spinning recycled cotton / material rubber filament composite yarn

[0039] Using the re-spreading and clustering composite spreader for biaxial spreading and splitting of the present invention, the viscose filament bundle is split and spread into two tows and two wire nets according to the above-mentioned splitting and spreading method , and then twist and combine with two bundles of recycled cotton fiber strands at the nip of the front roller respectively 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 rate of the surface silk screen is 1 / 2 of the compound ratio, that is, 15.255%. The content of the measured surface viscose filament is 13.2%. can be effectively displayed. The spun viscose filament is split into a smooth composite yarn wrapped with noil short fiber strands, and the hairiness index, twist angle, breaking stre...

[0040] Embodiment 2: spinning kapok / polyester filament composite yarn

[0041] Using the re-spreading and clustering composite spreader for biaxial spreading and splitting of the present invention, the polyester filament bundle is split and spread into two tows and two wire nets according to the above-mentioned splitting and spreading method, Then twist and combine with two bundles of kapok at the nip of the front roller respectively 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 silk screen is 7 / 10 of the composite ratio, that is, 22.78%. The measured surface polyester filament content is 21.9%, 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 staple fibers. The hairiness in...

Embodiment 3

[0042] Embodiment 3: Reuse cashmere / silk composite yarn

[0043] Using the re-expanding and clustering composite spreader for two-axis spreading and splitting of the present invention, the silk is split and spread into two tows and two wire nets according to the above-mentioned splitting and spreading method, and then The nip of the roller is respectively twisted and compounded with two bundles of 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, 1.969%. The measured surface silk content is 0.59%, 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 hairine...

Abstract

The invention relates to a composite filament spreader for respreading and clustering split bundles of two-shafting spread filament, a method and applications. The composite filament spreader comprises a double-yarn guide, a double-splitter, a double-guide wire guiding filament to ascend and descend, a coaxial two-way filament spreader and the like, and is arranged on a ring spinning machine by a fixed mount. The method for realizing respreading and clustering of split bundles of two-shafting spread filament comprises the steps of positioning two filaments by the double-guide wire, primarily flattening by a yarn guide rod, entering the double-splitter and synchronously respreading and splitting into four-bundle filaments; then, guiding two bundles to respective axis by the ascending double-guide wire, and feeding in by being attached to an upper front roller; feeding in the two-way filament spreader by descending and positioning of the descending guide-wire to spread into a silk screen, wherein the silk screen is clamped by a driving roll and a lower front roller and attached to the lower front roller for outputting. The composite filament spreader can be applied to synchronous and recompounded spinning of enhanced 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 composite spinning device for splitting and spreading protection of filament bundles 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. [...
