Embodiment 1

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

[0039] Adopt the biaxial system yarn spreader for filament beam splitting of the present invention, carry out splitting and spreading into two silk nets according to the above-mentioned splitting and spreading method of polyester filament bundle, and then separate with two silk nets at the nip of the front roller The bundles are recycled with cotton fiber strands for twisting and compounding to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun polyester filament is split into a smooth composite yarn wrapped with recycled noil short fiber strands. The hairiness index, twist angle, breaking strength, elongation at break and yarn fineness of the yarn are not uniform. Rates are 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; ...

[0040] Embodiment 2: Spinning soil seed wool / nylon filament composite yarn

[0041] Adopt the biaxial system yarn spreader for filament beam splitting of the present invention, carry out splitting and spreading yarn into two silk nets according to the splitting and spreading method of nylon filament bundle, and then separate with two silk nets at the nip place of front roller The strands of soil-grown wool fibers are twisted and composited to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun nylon filament split yarn is a smooth composite yarn wrapped with short fiber strands of soil species, 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 fiber such as flying flowers, shavings, and broken ends; Low, indicating good spinnability and high processing eff...

Embodiment 3

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

[0043] Adopt the two-axis silk spreader for filament beam splitting of the present invention, split and spread the silk into two silk nets according to the above-mentioned splitting and spreading method, and then return to the two bundles respectively at the front roller nip. Cashmere fiber strands are used for twisting and compounding to form a smooth composite yarn. The specific process parameters are shown in the table below. 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, breaking strength, elongation at break and unevenness of sliver fineness of the yarn are as follows listed in the table. Among them, the spinning rate is very high, which means that the fiber loss such as flying flowers, crumbs, and broken ends is very small; the number of hairiness is also very small, which means that the smoothness of the yarn i...

Abstract

The invention relates to a filament beam splitting two-axis unfolding device and application thereof. The unfolding device comprises a central snail wire, a flattening roller set, a splitting rod, a pair of snail wires which are used for guiding a two-axis filament, a pair of unfolding rollers and a driving roller, and the unfolding device is connected to a fixation support and is arranged on a ring spinning frame by virtue of the fixation support. A method for realizing filament beam splitting two-axis unfolding is characterized in that a filament is located on a central line of the flattening roller set by virtue of the central snail wire, a tow is unfolded by virtue of the flattening roller set; then the tow is symmetrically split into two tows by virtue of the splitting rod, the two tows are fed by virtue of the snail wires in a way of aligning the central line of each screw thread in an'inverted V' shape, the two tows are unfolded into a silk screen by virtue of the unfolding rollers; and the silk screen is output around the driving roller appressed to a front roller. The unfolding device can be applied to spinning of super-short, easy-flaky and easy-flying fibers, shorter and weak recycling fibers and protective, soft, smooth, high count and superlow count composite yarn.

Description

technical field [0001] The invention relates to a filament bundle split-bundle expansion protection type 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 filament has become more and more extensive, especially in the utilization of short fibers. In the process of textile processing, the 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 fibers cannot be spun or the spun yarns have the disadvantages of low strength and high hairiness. As a result, this type of short and weak fibers cannot be fully utilized. However, the composite yarn of filament covered staple fiber can make up for this deficiency and improve the utilization rate of staple fiber. [0003] It is difficult for...
