Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a double-sided unequal-length fabric and a weaving device thereof. Background Art

[0002] With the continuous development of materials science and textile technology, the application of advanced woven composite materials is becoming increasingly widespread. The application of some special fabrics can no longer meet the requirements of high-quality, efficient, and environmentally friendly production methods based on existing traditional production and processing methods. For example, the production of circular fabric products requires cutting out the center and edges of the entire woven fabric, making it difficult to form a one-piece product. The production of S-shaped flat fabric products also requires post-cutting. For special yarns such as carbon fiber and basalt fiber, this post-cutting process not only results in high material waste and high costs, but also requires a relatively complex cutting process. Furthermore, the processing of conical tubular composite preforms also requires cutting the fabric and then laying it layer by layer on a mold for processing. This method wastes material, and the presence of cuts on both sides and discontinuous weave reduces the mechanical properties of the fabric to a certain extent. Utility Model Content
