Embodiment 1

[0034] By adopting the intermittent overfeed composite spinning device and process of the symmetrical slope groove of the present invention, after the polyester filament bundle is overfed according to the above method, the intermittent overfeed wrapping and equal-feed core wrapping are carried out alternately with the kapok fiber strands. Composite spinning to form a two-component intermittent overfeed wrapping core-spun composite yarn. The specific process parameters are shown in the table below. The spun two-component intermittent overfeed wrapping core-spun composite yarn has an obvious appearance of changing wrapping effect, such as figure 2 The I, II, and III parts of the intermediate intermittent wrapping core-spun composite yarn 11 are the feeding and wrapping of the middle area I, the left notch area IIL, the right notch area IIR, the left jaw area IIIL and the right jaw area IIIR The effect of alternating cores. The yarn-making rate is very high, which means that th...

Abstract

The invention relates to an intermittent overfeeding composite spinning device with a symmetrical inclined plane groove, a method and application, wherein the device mainly comprises a bridging roller, a speed regulation roller, a handheld roller pair, an upper snail wire, a transposition air cylinder, a shift lever, a lower snail wire and a front upper roller with double inclined plane grooves. The method for intermittent overfeeding composite spinning comprises the steps that endless tows or yarns pass by the upper snail wire, pass through the handheld roller pair in a winding manner to be overfed, pass by the lower snail wire, are randomly or periodically transposed to the neutral, left and right parts among the middle area, the groove opening area and the jaw area of the front upper roller through the transposition air cylinder to be led in, are discharged from the jaw of a front roller, and are converged with short fiber yarns to form the intermittent overfeeding alternated wrapping and core composite yarns under twisting action. The method is unique and easy to realize, and can be used for the intermittent overfeeding transpositional wrapping composite yarns of a ring spinning frame, and the device corresponding to the method is simple and convenient to install.

Description

technical field [0001] The invention relates to an intermittent composite spinning device in the field of ring spinning, which alternates between overfeed wrapping and core wrapping, 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 shor...
