Embodiment 1

[0027] Example 1 Spinning recycled cotton / viscose filament upper cover type smooth composite yarn

[0028] Adopt the upper cover type splitting yarn spreading device for the sliver of the present invention, spread the viscose filament bundle according to the above-mentioned splitting and spreading method, and then carry out the process with the recycled cotton fiber sliver at the front roller nip. Twisting and compounding to form a smooth composite yarn, the specific process parameters are shown in the table below. The spun viscose filament upper cover is covered with a smooth composite yarn of recycled noil short fiber strands. 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 efficiency in yarn fo...

Embodiment 2

[0029] Example 2 Spinning soil seed wool / nylon filament upper cover type smooth composite yarn

[0030] Adopt the upper cover type split yarn spreading device for the slivers of the present invention, spread the nylon filament bundle according to the above-mentioned splitting and spreading method, and then add it to the soil wool fiber sliver at the front roller nip. Twisting and compounding to form a smooth composite yarn, the specific process parameters are shown in the table below. The spun nylon filament is covered with smooth and clean composite yarn of short fiber of soil seed hair. The hairiness index, twist angle, breaking strength, elongation at break and yarn fineness unevenness 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. During the sp...

[0031] Example 3 Spinning Recycled Cashmere / Silk Cover Type Smooth Composite Yarn

[0032] Adopt the upper cover type splitting yarn spreading device for the strands of the present invention, spread the silk bundles according to the above splitting yarn spreading method, and then carry out twisting and compounding with the recycled cashmere fiber strands at the nip of the front roller , to form a smooth composite yarn, the specific process parameters are shown in the table below. The spun silk top cover is covered with recycled cashmere short fiber strands and smooth composite yarn. The hairiness index, twist angle, breaking strength, elongation at break and unevenness of sliver fineness of the yarn are shown in the table below List. 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. During the spin...

Abstract

The invention relates to an upper covering type splitting yarn spreader for yarns. The yarn spreader is characterized by comprising a splitting roller, wherein the left end and the right end of the splitting roller are respectively provided with a thimble bracket; the thimble bracket on one end is connected with a fixed connection rod; one end of a tripod is connected with the fixed connection rod; the other end of the tripod is respectively connected with a pressing roller which is used for transferring spread long filament bunches to the splitting roller, a spreading roller which is used for spreading the long filament bunches and a locating yarn guider which is used for feeding the long filament bunches into a center position; and the fixed connection rod is arranged on a ring spinning frame. The invention further provides a composite spinning method and application for the yarn spreader. The yarn spreader provided by the invention can be used for spinning protective, soft, smooth and high-count composite yarns from ultrashort, easily-flaky and easily-flying fibers and shorter and weaker recycled fibers.

Description

technical field [0001] The present invention relates to a split yarn spreader used for the sliver upper cover type, a method of using the symmetrical split yarn spreader and its application, and belongs to the filament split spread protection compound spinning in the field of ring spinning. yarn technology field. Background technique [0002] Due to the shortage of fiber resources and petroleum energy, it is inevitable to use existing fiber resources with high efficiency, low consumption, ecology and recycling. Fiber is a kind of resource. A large amount of short fibers will be produced in textile processing, and a large amount of fiber materials will be discarded in textiles after human use. The reason is that these fibers are short or ultra-short, weak or fragile. In addition, in textile Short and weak fibers such as noil and noil during processing. Traditional spinning thinks that these fibers are difficult to spin or cannot be used at all, let alone high-efficiency, lo...
