Composite fabric information on the relationship between impurities and defects, yarn quality and spinning process

Impurities are non-fibrous substances, foreign fibers or colored fibers contained in fibers. Impurities not only affect the amount of fiber used in spinning, but also affect the spinning process and the quality of yarn and fabrics. Since coarse impurities are heavier than fibers, they are easily separated from the fibers and eliminated. Small impurities, especially small impurities associated with fibers, are difficult to remove during the spinning process. While impurities are being eliminated, coarse impurities are split into fragments due to the impact of the rotating machinery. Therefore, during the spinning process, although the weight of impurities is getting smaller and smaller, the number of particles is increasing, thus affecting the appearance of the final product. quality. Defects are substances that are harmful to spinning. They are generally difficult to remove during the spinning process. They are either wrapped in or attached to the yarn sliver, causing the yarn to deteriorate, causing more ends to break, worsening the appearance, and directly causing harm. Spinning production and the quality of the final product.
