    1. Clearing and falling objects, through the adjustment of a036, a076 dust bar gauge, the falling rate from 2.57% to 4.43%; combing the falling objects, by adjusting the distance behind the car, the falling rate from 5.2% It is about 6.5%. After the adjustment, the surface of the yarn is reduced in the amount of hemp and sesame seeds, and the chance of mixing in the weaving is also reduced, which can reduce the "three jumps" drop by 20% to 30%.
     
    2. The rapier loom has high quality requirements for the original yarn, and the smaller the long segment irregularity is, the better the requirement is. The general requirement is 3% to 4%, the dryness cv value is 20% to 25%, and the single yarn strength cv value. In 18% to 20%.
     
    3. To improve the quality of the joint, the end length is generally 1.5mm ~ 4mm is the best, the greater the degree of joints should be particularly to prevent small dumplings.
     
    4. Warping requirements to ensure that the "three spirits", that is, flexible rotation of the tension ring, flexible braking, automatic stop off the end of a flexible, while slightly heavier, so that the full width of warp yarn even.
