Embodiment 1

[0030] Example 1: Spinning recycled cotton / viscose filament bottom support type bright and clean composite yarn

[0031] Adopt the under-support type symmetrical splitting yarn spreader for the sliver of the present invention, spread the viscose filament bundle according to the above-mentioned splitting and spreading method, and then combine it with the recycled cotton fiber strand at the nip of the front roller Perform twisting and compounding to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun viscose filament under the support covers the smooth and clean composite yarn of recycled noil staple fiber. 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 me...

Embodiment 2

[0032] Example 2: Spinning soil seed wool / polyester filament under-supporting smooth composite yarn

[0033] Using the under-support type symmetrical splitting yarn spreader for the strands of the present invention, the polyester filament bundle is spread according to the above splitting spreading method, and then is carried out with the soil wool fiber strands at the jaws of the front rollers. Twisting and compounding to form a smooth composite yarn, the specific process parameters are shown in the table below. The spun polyester filament yarn is a smooth and clean composite yarn covered with short fibers 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 fibers such as flying flowers, crumbs, and broken ends; the number of hairiness is also very small, which means that ...

Embodiment 3

[0034] Example 3: Spinning recycled cashmere / nylon filament bottom support type smooth composite yarn

[0035] Using the under-support type symmetrical split yarn spreader for strands of the present invention, the nylon filaments are spread according to the above-mentioned split spread method, and then processed with recycled cashmere fiber strands at the jaws of the front rollers. Twisting and compounding to form a smooth composite yarn, the specific process parameters are shown in the table below. The spun nylon filaments are wrapped with cashmere staple fibers to cover the smooth and clean composite yarn. 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 fibers such as flying flowers, crumbs, and broken ends; the number of hairiness is also very small, which means that the yarn is smoot...

Abstract

The invention relates to a yarn strip lower supporting type symmetrical splitting yarn expander of short fibers during the spinning process, a method and a usage. The yarn expander is composed of a lower sliding yarn guide hook capable of guiding long tows downwards, an expansion horn mouth for primarily expanding the long tows, a herringbone thread splitting roller, a thimble bracket for supporting the splitting roller and a fixed connecting rod for connecting the thimble bracket with the lower sliding yarn guide hook, wherein the yarn expander is installed on a ring spinner through the fixed connecting rod. The device provided by the invention can be used for spinning protective, soft and smooth and high-count composite yarns of fibers which are ultra short and liable to drop chips and fly and short and weak recycled fibers.

Description

technical field [0001] The invention relates to a symmetrical split yarn spreader for the under-supporting type of whiskers, a method for using the symmetrical split yarn spreader and its application, and belongs to the filament splitting and unfolding protective composite in the field of ring spinning. The field of spinning technology. 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 a...
