Embodiment 1

[0035] By adopting the pre-position left-right displacement overfeeding compound spinning method of the present invention, the viscose filament bundle is overfed according to the above method, and then overfed compound spinning with the cotton fiber sliver to form a bicomponent superfed spinning method. To feed composite yarn, the specific process parameters are shown in the table below. The hairiness index, twist angle, breaking strength, elongation at break and unevenness of sliver fineness of the spun bicomponent overfed composite yarn are listed in the following table. Among them, the spinning rate is very high, which means that there is little loss of fibers such as flying flowers, chips, and broken ends; the number of hairiness is also small, which means that the finished yarn has good finish; the rate of broken ends at 1,000 spindles is extremely high due to the continuity and protection of filaments. Low, indicating that the yarn processing has good spinnability and hi...

Embodiment 2

[0037] By adopting the method for overfeeding compound spinning with front-type left and right displacement of the present invention, after the cotton yarn bundle is overfed according to the above method, it is overfed compound spinning with ramie fiber sliver to form a two-component overfed compound yarn , the specific process parameters are shown in the table below. The hairiness index, twist angle, breaking strength, elongation at break and unevenness of sliver fineness of the spun bicomponent overfed composite yarn are listed in the following table. Among them, the spinning rate is very high, which means that there is little loss of fibers such as flying flowers, chips, and broken ends; the number of hairiness is also small, which means that the finished yarn has good finish; the rate of broken ends at 1,000 spindles is extremely high due to the continuity and protection of filaments. Low, indicating that the yarn processing has good spinnability and high processing effici...

Embodiment 3

[0039] By adopting the pre-position left-right displacement overfeeding compound spinning method of the present invention, after the PTT filament bundle is overfed according to the above method, it is overfed compound spinning with the kapok short fiber sliver to form a bicomponent superfed spinning method. To feed composite yarn, the specific process parameters are shown in the table below. The hairiness index, twist angle, breaking strength, elongation at break and unevenness of sliver fineness of the spun bicomponent overfed composite yarn are listed in the following table. Among them, the spinning rate is very high, which means that there is little loss of fibers such as flying flowers, chips, and broken ends; the number of hairiness is also small, indicating that the finish of the finished yarn is good; the rate of broken ends at thousand spindles is extremely high due to the continuity and protection of filaments Low, indicating that the yarn processing has good spinnabi...

Abstract

The invention relates to a prepositive left and right deflection overfeeding composite spinning device and a process as well as application of the device and the process. The device mainly comprises a bridging roller, a speed regulation roller, an overfeeding roller, a reciprocating rod, a deflection yarn guide hook and a reset spring. A composite spinning method adopting the device is characterized in that through the rotation of a front roller, the bridging roller, the speed regulation roller and the overfeeding roller drive an outer shaft system through friction, the overfeeding of long yarn beams or yarns is realized at the front part of the front roller, and in addition, the long yarn beams or the yarns are gathered with output short fiber whisker strips to form double-component overfeeding composite yarns through twisting. The method is unique and is easy to realize, the corresponding device is simple and compact and is convenient to install, and the overfeeding wrapping composite spinning of the short fiber whisker strips on a ring spinning frame can be realized.

Description

technical field [0001] The invention relates to a composite spinning device for reciprocating displacement and variable overfeed wrapping in the field of ring spinning and a composite spinning process using the device. Background technique [0002] The wrapped yarn fabric has better appearance, feel and comfort, so this type of fabric is more popular in the market. Since the fancy effect of wrapping yarns depends on the overfeed of the filament tow or yarn, the traditional wrapping yarns are all under-fed, that is, the filament tow is tensioned, so it is spun on a traditional ring spinning machine. The key technology for making this type of wrapped composite yarn lies in the method and device for overfeeding the filament tow or yarn. [0003] There are related researches on wrapping composite yarn at home and abroad. The method usually used is to introduce the filament yarn into the middle roller or front roller after passing through the yarn guide rod, and then combine it ...
