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 is split into a smooth composite yarn wrapped with soil-type short fiber strands, and the yarn hairiness index, twist angle, breaking strength, elongation at break and yarn fineness unevenness 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 efficiency in ya...

Embodiment 3

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

[0043] Adopt the two-axis silk spreader used for filament beam splitting of the present invention to 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 at the front roller nip respectively. 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 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 there is very little loss of fiber such as flying flowers, shavings, and broken ends; Low, indicating good spinnability and high processing efficiency in yarn forming. ...

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 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...
