Research of the weft-curved technology of woven fabrics

Research of the processing technology to make the weft be curved shape in woven fabrics. We demonstrate the feasibility of using the tension method, the beating-up method, the yam method to product weft-curved fabrics. Through weaving samples in laboratory, we discussed the actual effect and existing problems of the three methods, summarized the technical methods that we should choose to make weft-curved fabrics be in industrialized production and the new ideas to develop weft-curved fabrics. We believe: If we use the big-belly yarns containing PVA fibers to make weft-curved fabrics, its effect is the best and symbiotic defects are the most slightly. At the same time, with the low technical difficulty and high production efficiency, it should be the preferred technical approach to develop weft-curved fabrics. The technology to develop weft-curved fabrics is more suitable for the development of new staple products and yarn-dyed striped grid, new jacquard products.
