Fiber Properties And Spinning Methods Play A Decisive Role in Yarn Performance

During the twisting process of ring-spun yarn, due to fiber transfer, from the inner layer of the yarn to the outer layer, and then from the outer layer to the inner layer, the transfer is repeated many times. Increase or decrease alternately. At this time, the long-length fibers tend to the axis of the yarn more, and the short-length fibers tend to the outer layer of the yarn. The finer fiber tends to the axis of the yarn, and the thicker fiber tends to the outer layer of the yarn. The fibers with a smaller initial modulus are more located in the outer layer, and the fibers with a larger initial modulus are more located in the inner layer. Reasonable selection of fibers with different properties can be spun into yarns of different styles to adapt to different fabric uses or improve wearability. Since the length, fineness and cross-sectional shape of the fiber can be arbitrarily selected for the chemical fiber, the outer garment fabric should be a blend of chemical fiber and cotton with a slightly thicker fiber and a shorter length to increase the hairy feel on the surface of the yarn. Underwear fabrics should choose chemical fibers with slightly thinner fibers and longer lengths, so that cotton fibers are in the outer layer of the yarn to improve moisture absorption and wearing comfort.
