Description
Technical Field
The invention relates to the field of textiles, in particular to a special-shaped shuttle for weaving bunched filaments.
Background
The bundle filament is a filament with the section width far larger than the height formed by a plurality of filaments arranged in parallel, the application field of the bundle filament fabric is wide, and the bundle filament fabric has excellent practical value in a plurality of application fields, for example, the carbon fiber bundle filament fabric can be applied to a plurality of fields such as buildings, military industry, automobiles, high-performance bicycles and the like, and the carbon fiber bundle filament fabric has incomparable advantages in a plurality of application fields. Therefore, there is an increasing interest in weaving bundle-like filament fabrics.
In the traditional spinning process, the yarn generally bears force and exits in a spiral line along the axial direction of a spinning shaft, the yarn can twist, the section shape of the common yarn is generally circular, and the twisting has little influence on the appearance and the performance of the yarn, so that the yarn can be woven by using a common shuttle, the section shape of a bundle filament is generally flat, and the change of the twisting form is large once, so that the appearance, the mechanical property and the like of the finally prepared bundle filament fabric are greatly influenced, and therefore, the bundle filament can only be woven by using a special shuttleless loom when being used as the yarn for weaving. The length of the bunchy filament used by each yarn is close to the breadth of the loom, the edge of the fabric is seriously fluffed, when the specific loom is adopted to weave the fabric obviously smaller than the breadth of the loom, a large amount of raw materials are easily wasted, if the wide fabric is cut at the later stage to obtain the narrow fabric, the fluffy phenomenon of the fabric is more obvious, the prepared fabric needs to be subjected to post-treatment, a large amount of manpower is consumed in the post-treatment process, and the finally prepared bunchy filament fabric is far inferior to the plain bunchy filament fabric in appearance and performance.
