Embodiment 1

[0039] Embodiment 1: Spinning recycled cotton / Tencel filament composite yarn

[0040] Adopt the double-stick differential type two-stage split yarn spreading device of the present invention to spread the Tencel filament (cellulose fiber) by pressing the supporting type splitting spreading method to obtain the lower supporting wire mesh, such as figure 2 and Figure 4 shown. Then twist and wrap the recycled cotton 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 Tencel filaments are split and covered with recycled noil short fiber strands for clean and clean composite yarn. listed in the table 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 smoothness of the yarn is good; Low, indicating good spinnability an...

Embodiment 2

[0041] Embodiment 2: Spinning soil seed wool / polyester filament composite yarn

[0042] Using the double-stick differential type two-stage split yarn spreading device of the present invention, the polyester filament bundle is spread according to the upper cover type split yarn spreading method to obtain the upper cover screen, such as image 3 shown. Then at the nip of the front roller, it is twisted and wrapped with the soil wool fiber strands to form a smooth composite yarn. The specific process parameters are shown in the table below. The spun polyester filaments are split and coated with short fibers of soil seed hair and smooth 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...

Embodiment 3

[0043] Embodiment 3: Reuse cashmere / silk / silk composite yarn

[0044] Using the double-stick differential type two-stage split yarn spreading device of the present invention, the silk is spread through the upper cover and lower support combined type according to the above split yarn spreading method, and a bundle of silk passes through the single-circle yarn guide hook 11 , that is, the upper cover path; and another bundle of silk passes through the lower guide yarn hook 12, that is, the lower support path, and then enters the respective primary splitting roller 2 and double splitting roller 3 to spread the yarn into a silk web, as image 3 and Figure 4 shown. Then twist and combine with 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 is split and coated with cashmere short fiber strands and the smooth composite yarn. The hairiness index, twist angle, ...

Abstract

The invention relates to a twin-roll differential type two-stage splitting yarn unfolding device, a spinning method and application of twin-roll differential type two-stage splitting yarn unfolding device. The twin-roll differential type two-stage splitting yarn unfolding device consists of a positioning a yarn guiding hook, two symmetrical splitting rolls for unfolding the yarns and clutches thereof, a differential mechanism for carrying out transmission on two split rolls as well as a fixing frame for mounting various parts of the yarn unfolding device on a ring spinning frame. According to the spinning method, long filaments are positioned at the splitting midline of a primary splitting roll through a yarn guiding hook; primary splitting and yarn unfolding are finished by winding; and then secondary splitting and yarn unfolding are finished by symmetrically winding and secondarily splitting roll. Due to the utilization of speed difference of the two splitting rolls, the splitting and yarn unfolding can be effectively and controllably realized under the rotation of splayed threads. The yarn unfolding device can be applied to spinning of protective, soft and smooth and high-count composite yarns formed by super-short fibers, fibers which easily fall scrip and easily fly as well as extremely-short and extremely-weak reclaimed fibers.

Description

technical field [0001] The object of the present invention is to provide a two-roller differential type two-stage split yarn spreader, the spinning method and its application using the device, which belong to the filament bundle splitting and unfolding protective compound spinning in the field of ring spinning. yarn technology field. 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 fib...
