I. Causes of warp yarn breaks (excluding the quality of the original yarn and preparation reasons)

1. The height of the heald frame is too high and uneven.

2. The opening is too large and too small, too early and too late.

3. The warp yarn route is too short (the back beam passes before), and the warp yarn tension is too high.

4. The position of the back beam and the end of the warp beam is high, and the tension of the upper and lower layers is too wide.

5. The distance between the meniscus and the heald frame is too far or too low.

6, air conditioning, humidity is too high or too low. (Especially hemp yarn responds the most)

7, the sword neck, steel reed, heald, menopause, sword belt and other rough.

8. The oversupport position is too high, and it should be 1mm from the lowest position.

9. Knot the yarn tail and flying debris into the warp.

10. The duty of the car on the warp yarn is not good, and it is bad to handle the warp yarn.

Reasons for weft break

1. Weft yarn is too weak, loose twisted yarn, large knots, cottonseed crumbs, and flying flower loops.

2. The winder is too strong, the tension is too high, and the forming is bad.

3. The side support bumps too far forward, and there must be a gap of at least 1mm from the steel reed.
