When the air-jet looms produce high-density fabrics, if the sizing technique is not good, the warp hairiness will cause the adjacent warp yarns to entangle each other to cause the opening to be unclear. The hairiness of more than 3 mm on the warp yarn will also cause the weft insertion failure. In the case of a 30-inch spun yarn, if the length of the yarn on the yarn is 3 mm, the diameter of the spun yarn will increase by 18 times. The initial opening height of the air jet loom is 3.5 mm. Due to the presence of hairiness, the effective height of the loom opening is reduced, the warp yarn opening is unclear, and the weft yarn is blocked from being blocked.
According to statistics, the 1/3 to 2/3 of the air jet loom is related to the yarn hairiness. The length of the warp and weft yarn is more than 3 mm. On the one hand, the effective diameter of the weft yarn is also increased. On the one hand, the adjacent warp yarns are entangled, resulting in unclear openings, difficulty in weft insertion, and weaving defects, which affect product quality. 70% of the air-jet looms are caused by latitudinal reasons. Therefore, in the activity of improving the efficiency of the air-jet looms, reducing the latitudinal stop is the main contradiction. Among the factors causing the latitude stop, the hairiness is important. one of the reasons. Therefore, the hairiness on the conductive yarn is detached due to friction in the downstream processes, forming a pollen environment, endangering human health, and also creating new defects that degrade the quality of the yarn and fabric, and negatively increase the efficiency of the air jet loom. Impact.
