Embodiment 1

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

[0039] Adopt the coaxial two-way yarn spreading device that is used for filament beam splitting of the present invention, carry out splitting and spreading into two silk nets with viscose long filament bundle by above-mentioned splitting and spreading method, and then at the front roller nip place and respectively Two bundles of recycled cotton fiber strands are twisted and composited to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun viscose filament is split into a smooth composite yarn wrapped with noil short fiber strands, and the hairiness index, twist angle, breaking strength, elongation at break and yarn fineness of the yarn are different The uniform rate is listed in the table below. Among them, the spinning rate is very high, which means that there is very little loss of fiber such as flying flowers, shavings, and broken ends; Low, ind...

[0042] Example 3: Recycling cashmere / nylon filament composite yarn

[0043] Adopt the coaxial two-way yarn spreading device for filament beam splitting of the present invention, carry out splitting and spreading yarn into two silk nets with nylon filament according to above-mentioned splitting yarn spreading method, then separate with two beams at the nip of front roller Recycled cashmere fiber strands are twisted and composited to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun nylon filament is split into a smooth composite yarn wrapped with cashmere short fiber strands, and the hairiness index, twist angle, breaking strength, elongation at break and yarn fineness unevenness of the yarn See list below. Among them, the spinning rate is very high, which means that there is very little loss of fibers such as flying flowers, crumbs, and broken ends; the number of hairiness is also very small, which means that the yarn is smoo...

Abstract

The invention relates to a coaxial bidirectional filament spreading device of a beam-splitting filament and application. The filament spreading device is composed of a centering yarn guide hook, a spreading disk for spreading the filament beam, a splitting separator, a filament spreading roller for spreading a splitting filament layer in a bidirectional way, a driving roller at the same speed as a front roller and the like, is connected to a fixed frame and is mounted on a ring throstle through the fixed frame. A method for spreading the beam-splitting filament coaxially and in the bidirectional way comprises the steps of: locating a filament on a central line of a flat bottom groove of the spreading disk by the centering yarn guide hook and winding on the spreading disk to finish the spreading of the filament beam; then splitting the filament symmetrically by the splitting separator to form two filament beam layers with a certain interval, enabling the two filament beam layers to enter into respective one-way filament spreading zones and respectively spreading the filament beam layer towards left and right under the action of a screw thread groove to form a filament mesh; and outputting the filament mesh by surrounding and being close to a driving roller of the front roller. The filament spreading device can be applied to spinning of protective type soft, smooth, high-count composite yarns and superfine branches of fibers which are ultra-short, easy to drop scraps and easy to generate flying and shorter and weaker 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 and the 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 is difficult for a single type of fiber and a...
