Selection of spinning parameters Composite fabric information

Because the physical properties of wool, silk, and linen fibers are quite different, the mutual cohesion of the fibers during blending is poor, and the yarn evenness, hairiness, and hairiness are very low compared with the full wool yarn of the same number. Difference. Therefore, from the perspective of spinning, first of all, the twist coefficient and twist direction of single yarns and strands must be reasonably selected so that the yarn strength, wear resistance, and elastic elongation meet the requirements of high-speed weaving of rapier looms. Secondly, It is to improve the uniformity of yarn dryness, reduce the content of hair particles, hairiness and thick details, to ensure smooth weaving and stable quality of the finished fabric. 1. Yarn twist coefficient, twist degree and twist direction The selection of the twist coefficient, twist degree and twist direction of single yarns and strands should not only be based on product style, feel, strength and other factors, but also should fully consider the characteristics of the three fibers after mixing. Spinnability, and its impact on high-speed weaving on rapier looms. This variety is made of wool, silk, and hemp fibers blended in a certain proportion. Since hemp fiber is generally hard to the touch and has strong torsion resistance, it is difficult to twist during spinning. Spun silk is slippery and waxy and has poor cohesion, while wool The fiber feel is between the two, and the cohesion is better, so spinning is very difficult. The selection of twist coefficient, twist return and twist direction is inappropriate, the yarn breakage rate in spinning and weaving is high, and the style and feel of the finished product cannot meet the design requirements. 2. In the spinning process, the main factors that lead to poor evenness evenness and easy generation of hair particles and hairiness include: improper selection of process parameters, poor state of process components and machinery, unreasonable operation, and various kinds of stress during processing. Accidental stretching caused by unexpected tension, large changes in temperature and humidity, and prompt cleaning work. Therefore, the spinning process must be modified for the requirements of single yarn production.
