Description

Coaxial and bi-directional filament spreader for splitting filaments and its application

technical field

The invention relates to a filament bundle splitting and spreading protection composite spinning device in the field of ring spinning and the application of the device.

Background technique

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. This rod just causes this kind of on the short side, weak fiber can not be fully utilized. However, the composite yarn of filaments covering staple fibers can make up for this deficiency and improve the utilization rate of staple fibers.

It is difficult for a single type of fiber and a single structure of yarn to overcome the deficiencies of the fiber itself. The composite yarn composed of different raw materials can maximize the excellent characteristics of different fiber materials and make up for the deficiencies of different fibers to the greatest extent. And the composite yarn The structure of the composite yarn can also give it more excellent quality, and the composite yarn can have the advantages of both filament and spun yarn.

At present, the staple fiber/filament composite yarn production devices are partially modified on the basis of the traditional ring spinning mechanism. Such as Wang Wenge and Li Baocang's utility model patent (patent application number: CN200320121270.5), a partial mouth collector is set on the spinning support, the yarn sliver enters the front top roller through the passage of the partial mouth collector from the apron inlay, and the filament passes through the The front end of the collector merges with the sliver at the front top roller, so that the sliver and filament form a stable twisting triangle. However, how to separate the processed filament bundles into single filaments has become the premise of filament-short fiber composite spinning, and a device is needed to quickly and effectively separate the filament bundles into single filaments. The patent reports about the splitting of filament bundles into single filaments, such as Ma Qiang’s patented continuous fiber bundle dispersion device (publication number CN1811025A), are mainly composed of an air separator and a carding device, and a hollow cylinder is arranged in the air separator. There is a splitting chamber at the upper port, and the bottom of the splitting chamber is a splitting plate with a number of ventilation holes. The carding device is equipped with a carding groove, and the splitting process is completed by air pressure. Yu Mingwei's patent decomposes the tow into parallel monofilament rewinding/unwinding equipment and method (publication number: CN1884026A), which consists of a reed splitter and a tension control device. The tow is broken up into parallel monofilaments. Joseph Lee Lifke's patented method and device for separating fiber bundles (METHOD AND APPARATUS FORSPEREADING FIBER BUNDLES) (patent number: US6049956) consists of several dispersion drums, and the fiber bundles are dispersed by changing the angle of the discs at both ends of the dispersion drum , this method has many mechanical components and requires high mechanical coordination.

The above-mentioned related methods, first of all, are spinning for the purpose of changing the yarn style, fancy or high-branching of fibers with excellent spinnability, and are powerless for fibers with poor spinnability or cannot be spun at all. ; Second, it is not suitable for highly branched or even ultra-highly branched spinning of short and weak fibers.
