A special-shaped shuttle for weaving bundled filaments

Abstract

The invention relates to a special-shaped shuttle used for bundle-shaped filament weaving. The special-shaped shuttle includes a shuttle shell and a weft-loading bobbin which is arranged inside the shuttle shell, wherein the shuttle shell is of a hollow structure and gradually decreases from the middle section of the shuttle shell to both ends in size, and a horizontal bar is fixed in a cavity in the middle section of the shuttle shell; the weft-loading bobbin is of a hollow cylindrical structure, and the horizontal bar is sleeved and matched with the the weft-loading bobbin in a gap mode; a narrow and long yarn guide hole is formed in the position, above the weft-loading bobbin, of the shuttle shell, and the projection of the yarn guide hole coincides with the central axis of the weft-loading bobbin; the width of the yarn guide hole is smaller than the width of the cross section of a bundle-shaped filament. According to the special-shaped shuttle used for bundle-shaped filament weaving, radial unwinding of the bundle-shaped filament along the weft-loading bobbin is achieved, and the defect that since the bundle-shaped filament easily twists, yarn cannot be used for weaving is overcome when weaving is conducted with a shuttle; therefore, fabric in arbitrary width can be woven without the problem of waste of raw materials, edges of the fabric which is obtained by weaving the bundle-shaped filament are clean and tidy, and no fluff phenomena emerge.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a special-shaped shuttle for weaving bundled filaments. Background technique [0002] Bundled filaments are filaments whose section width is much greater than the height and are composed of multiple monofilaments arranged in parallel. Bundled filament fabrics have a wide range of applications and have excellent practical value in many application fields, such as carbon fiber bundles Carbon fiber bundle filament fabrics can be used in various fields such as construction, military industry, automobiles and high-performance bicycles, and carbon fiber bundle filament fabrics have unparalleled advantages in many application fields. Therefore, weaving bundled filament fabrics has attracted more and more attention.

AI Technical Summary

Problems solved by technology

[0003] In the traditional spinning process, the yarn is generally forced to withdraw in a helical line along the axial direction of the spinning shaft. During this process, the yarn itself will be twisted. The influence of its appearance and performance is small, so ordinary shuttles can be used for weaving. The cross-sectional shape of the bundled filament is generally flat, and once it is twisted, the shape changes greatly, so that the final bundled filament fabric is made The appearance and mechanical properties are greatly affected. Therefore, when weaving bundled filaments as yarns, only special shuttleless looms can be used for weaving.

On the special shuttleless loom, the yarn is generally cut in the process of weaving the fabric. The length of the bundled filaments used for each yarn is close to the width of the loom, and the edge of the fabric is severely fluffed. When the loom weaves fabrics that are obviously smaller than the width of the loom, it is easy to cause a lot of waste of raw materials. If the wide-width fabrics are cut to obtain narrow-width fabrics in the later stage, the fabric fluffing phenomenon will be more obvious, and the resulting fabrics need to be post-processed. , the post-processing process requires a lot of manpower and material resources, and the final bundled filament fabric is far inferior to the smooth edge bundled filament fabric in terms of appearance and performance.
