Embodiment 1

[0031] Using the pre-overfeed wrapping composite spinning method of the present invention, after the polyester filament bundle is overfed according to the above method, it is wrapped with cotton fiber strands for composite spinning to form a two-component overfeed 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 yarn fineness of the spun bi-component super-fed composite yarn are listed in the following table. Among them, the spinning rate is very high, which means that there is little fiber loss such as flying, chipping, and end breakage; the number of hairiness is also very small, which means that the finished yarn has a good finish; the rate of breakage at 1,000 spindles is extremely high due to the continuity and protection of the filament Low indicates that the yarn processing has good spinnability and high processing efficiency. There is no obvious fiber...

Embodiment 2

[0033] Adopting the composite spinning method for front-type overfeeding and wrapping of the present invention, the cotton yarn filament bundle is overfed according to the above method, and then it is wrapped with wool fiber strands for composite spinning to form a two-component overfeeding 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 yarn fineness of the spun bi-component super-fed composite yarn are listed in the following table. Among them, the spinning rate is very high, which means that there is little fiber loss such as flying, chipping, and end breakage; the number of hairiness is also very small, which means that the finished yarn has a good finish; the rate of breakage at 1,000 spindles is extremely high due to the continuity and protection of the filament Low indicates that the yarn processing has good spinnability and high processing efficiency....

Embodiment 3

[0035] Adopting the composite spinning method for front-type super-feeding and wrapping of the present invention, the spun filament filament bundle is super-fed according to the above method, and then it is wrapped and spun with polyester staple fiber to form a two-component super 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 yarn fineness of the spun bi-component super-fed composite yarn are listed in the following table.

Abstract

The invention relates to a front overfeeding composite spinning device, a process and application. The device mainly comprises a tension disc, a bridging roller, a speed regulating roller, a conical roller, a moving guide rod, a yarn guide hook and a guide rod moving rack. The spinning process comprises the following steps of: driving the bridging roller, the speed regulating roller and the conical roller by using rotation of a front roller to frictionally drive filament bundles or yarns to be overfed to the front part of the front roller, and gathering and twisting the filament bundles or the yarns and output short fiber slivers to form double-component overfeeding composite yarns. The composite spinning process is unique and easy to implement, the corresponding device is compact and convenient to install, and the device and the process can be used for overfeeding wrapping composite spinning of the short fiber slivers on ring spinning frames.

Description

technical field [0001] The invention relates to a composite spinning device for overfeed wrapping in the field of ring spinning and a composite spinning process using the device. Background technique [0002] Wrapped yarn fabrics have better appearance, feel and comfort, so this kind of fabrics are more popular in the market. Since the fancy effect of wrapped yarn depends on the overfeeding of filament bundles or yarns, traditional wrapped yarns are all underfed, that is, the filament bundles are under tension, so they are spun on traditional ring spinning machines. The key technology for making this type of wrapped composite yarn lies in the overfeeding method and device of filament bundle or yarn. [0003] There are related studies on wrapping composite yarns at home and abroad. The usual method is to introduce the filament yarn through the yarn guide rod into the middle roller or front roller, and merge with the short fiber strands before entering the front roller. Comp...
