Design of mid-length fiber fabrics Composite fabric information

1. Determination of the number of fibers in the yarn cross-section. Since medium-long fibers are made using cotton textile equipment to make wool-like products, and their fibers are thinner and shorter than wool fibers, in order to ensure the quality of the yarn, the number of fibers in the yarn cross-section should be More fiber than wool. But if it is too much, the woven fabric will be prone to fluffing, pilling and wrinkling, and will lack a wooly feel. If it is too little, the finished yarn will be poor in dryness, wear resistance and strength. The appropriate number of fiber roots should be selected. Generally, the number of fibers in 65/35 polyester-viscose blended yarn or 50/50 polyester-nitrile blended yarn is 50-80. The best number is 55-60. 2. Selection of fiber radial distribution The selection of fiber radial distribution refers to the distribution of fibers within a certain cross-section in the yarn. It should be determined according to the requirements of product performance and style. It is determined by the fiber distribution rules of blended yarns. realized. Medium-long fiber fabrics require a wool-like style, and thick and elastic fibers should be used to distribute on the yarn surface. Therefore, when blending polyester and acrylic, acrylic fiber is relatively fluffy and should be thicker and shorter than polyester. When blending polyester and viscose, viscose fiber is not wear-resistant and has poor elasticity, so it should be slender.
