The weaving of the yarn machine tension not only directly affect the operation of production, but also will seriously affect the quality of the product, some products of rib gear, a few pry gear, human pressure on the surface of the unilateral gear, etc., are due to the yarn machine tension caused by improper, specifically, the yarn machine tension on the quality of the product is roughly the following aspects:

1 Effect on the rate of severing

The warp thread goes through thousands of times of stretching and friction of guide rollers, heddle and reed from the warp thread to the woven fabric. The tension on the thread increases, which is easy to cause fatigue and breaks in the weak link of the warp thread. Therefore, excessive tension on the thread is the main reason for the broken end of the warp thread. Some people have done experiments on a certain fabric, adjusting the tension on the machine, the flatness of the yarn, the position of the yarn and other related factors, so that the rate of the end of the yarn from0.839 root/Taiwan · hour, reduced to 0.175 root/Taiwan · hour. Is it possible to think that the smaller the tension on the machine, the lower the breakage rate? According to the analysis, the beating-up force on the general fabric is not 90 °, so the beating-up force can be decomposed into the force F along the fabric direction and the force f perpendicular to the fabric direction. When the beating-up force is constant, if the warp tension decreases, the beating-up force F in the silk direction is bound to decrease, thus the fabric forming area and the beating-up area will increase. In this way, it not only increases the friction between the warp wire and the heddle, but also causes the warp wire to produce a "bloated plug" phenomenon in front of the reed, resulting in an increase in broken ends. Therefore, too small warp wire machine tension is also unfavorable to weaving.

2 Influence on fabric shrinkage

If the warp tension is large, when the warp and weft are interwoven, the warp compression of the weft will increase the buckling of the weft, thus increasing the internal stress of the weft. When the fabric is involved in the take-up roll, especially after the machine, the tension of the warp yarn disappears, and the weft yarn is due to internal stress.The "resistance" effect will produce a greater counter pressure on the warp filament, resulting in an increase in warp shrinkage and a decrease in weft shrinkage.

3 Influence on fabric feel and appearance

The size of the tension on the silk machine has a great influence on the feel and appearance of the fabric. If the tension on the silk machine is properly controlled, the silk surface of the fabric will be flat, the texture will be clear and the feel will be good. However, if the tension on the silk is too large, the silk surface will not be full enough due to excessive elongation, and if the tension on the silk machine is too large, the fabric is likely to produce"Thin mouth".
