Embodiment 1

[0035] Using the one-side two-groove intermittent overfeeding composite spinning method of the present invention, after the PTT filament bundle is overfed according to the above method, the composite spinning of intermittent overfeeding with kapok fiber strands is carried out to form a two-component intermittent For overfeed wrapping composite yarn, the specific process parameters are shown in the table below. The spun two-component intermittent overfeed wrapped composite yarn has an obvious appearance of variable wrapping effect, such as image 3 The I, II, and III parts of the intermittent wrapping composite yarn 11 are the effects of feeding and wrapping in the I, II, and III areas. The yarn-making rate is very high, which means that there is little fiber loss such as flying flowers, crumbs, and end breaks; the end-break rate is extremely low due to the continuity and protection of filaments at the time of thousand spindles, which means that the spinnability of yarn process...

Embodiment 2

[0037] Using the one-side two-slot intermittent overfeed composite spinning method of the present invention, after the cotton yarn is overfed according to the above method, it is combined with cotton fiber strands to perform intermittent overfeed composite spinning to form a two-component intermittent overfeed composite spinning method. Wrapped composite yarn, the specific process parameters are shown in the table below. The spun two-component intermittent overfeed wrapped composite yarn has an obvious appearance of variable wrapping effect, such as image 3 The I, II, and III parts of the intermittent wrapping composite yarn 11 are the effects of feeding and wrapping in the I, II, and III areas. The yarn-making rate is very high, which means that there is little fiber loss such as flying flowers, crumbs, and broken ends; the broken end rate is extremely low due to the continuity and protection of filaments at the time of thousand spindles, which means that the spinnability of...

Embodiment 3

[0039] Using the one-side two-groove intermittent overfeed composite spinning method of the present invention, after the nylon filament bundle is overfed according to the above method, it is compositely spun intermittently overfeed with wool short fiber strands to form a two-component For intermittent overfeed wrapping composite yarn, the specific process parameters are shown in the table below. The spun two-component intermittent overfeed wrapped composite yarn has an obvious appearance of variable wrapping effect, such as image 3 The I, II, and III parts of the intermittent wrapping composite yarn 11 are the effects of feeding and wrapping in the I, II, and III areas. The yarn-making rate is very high, which means that there is little fiber loss such as flying flowers, crumbs, and broken ends; the broken end rate is extremely low due to the continuity and protection of filaments at the time of thousand spindles, which means that the spinnability of yarn processing is good a...

Abstract

The invention relates to a singe-side two-groove intermittent overfeeding composite spinning device, a process and application. The device mainly comprises a bridging roller, a speed regulation roller, a tension bowl, holding rolls, an electromagnetic switch, a triggering rod, a swinging yarn guide hook and a front upper roller, wherein the front upper roller is provided with two grooves. The composite spinning process is characterized in that long yarn beams or yarns go around and pass through the holding roll pair through the tension bowl to realize the overfeeding, then, the left and right random or periodic swinging positioning is carried out at two groove opening regions and one vice jaw region through the swinging yarn guide hook, and the long yarn beams or the yarns are fed into the vice jaw of a front roller, and are then gathered with short fiber whisker strips under the twisting effect to form intermittent overfeeding wrapping composite yarns after going out of the vice jaw of the front roller. The method is unique and is easy to realize, the corresponding device is simple and compact and is convenient to install, and the intermittent overfeeding conversion wrapping composite spinning of a ring spinning frame can be realized.

Description

technical field [0001] The invention relates to a two-slot intermittent overfeeding and wrapping composite spinning device 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 enterin...
