Woven fabric knowledge
High density fabrics in woven fabrics have special requirements for yarns. For example, densely poplin, the requirements for warp strength and knots are more stringent, fine length, fineness, high strength, high grade fine cotton or part of long staple cotton should be selected; Corduroy, the higher the gloss of the fabric, you should use a good color of fine cotton or some long-staple cotton, with particular attention to the regional differences in the raw cotton and harvesting differences, in order to prevent color.
Most woven cotton fabrics need to undergo dyeing, bleaching or printing and other dyeing and finishing processes. Different dyeing and finishing processes have different requirements for the yarns used in the grey fabrics. Light-colored cloth requires less neps, dark cloth requires less white stars. Because the nep is made of fiber kink, the structure is looser than the yarn, easy to color, after the dyeing shows dark ideas, has an impact on the appearance of light-colored cloth, so you should avoid the choice of low-grade cotton or late cotton; white star is dying Fiber formation is not easy to see on the grey fabric, but it is poor in color absorption and appears white after dyeing, which affects the appearance of dark fabrics, especially for the yarns of dark grey fabrics with high density, such as poplin, khaki, etc. When mixing with cotton, avoid mixing with immature fibers and stiff cotton.
After bleaching, the bleached cloth can remove most of the impurities and a small part of the nep. When blending with cotton, a low-grade raw cotton can be used. Most of the fabrics on the printed fabric can be concealed by the suit, and it is not easy to detect it. You can select grades of raw cotton or mix low-grade cotton and flowers.
There are half-line fabrics and full-line fabrics in the woven fabrics, and the latter is used for the warp and weft. The strands are made from single yarns and twisted together, and the strands can be improved. The knots are also partially covered and are not easy to reveal. The utilization of fiber strength in the strands is higher than that of single yarns. Can choose to use lower than the original cotton grade cotton, inferior strength of the original cotton.
