Six causes and six countermeasures of “wool silk” and “warp breakage” in water-jet weaving

  1. The physical and mechanical properties of raw materials are not ideal, the fiber fracture strength is low, and the warp thread cohesion is poor. In the weaving process, the reed and heald wire cannot withstand repeated friction, resulting in the fluff or breakage of warp thread single fiber.

2, warping, and axis process guide wire grooving, damaged or by wire unwound shake firm, wrapped, so that the fiber strength, elongation damage, mechanical properties deterioration, when the production and processing tension exceeds the yield value of its strength, elongation, resulting in single fiber fracture and broken.

3, loom reed, heald wire grooving, damage, warp wire can not afford its repeated high frequency friction and fuzz broken head. The faster the loom speed, the more serious the warp breakage.

4, warping machine wool monitor failure, so that the raw material of their own wool, long knot escape or stop workers break the joint when the knot is too large, too long, weaving by winding the warp side of the silk, resulting in unclear opening, pull off the end.

  1. In the operation of the loom, the opening height of the warp thread has a great influence on warp and warp breakage, because the elongation of the warp thread is directly proportional to the opening height in the loom. If the loom has a large opening height, the elongation of the warp thread will be large, and excessive elongation will result in pilling and breakage of the warp thread.
  2. The friction motion of heald also has a great influence on warp and warp warp breakage when the loom is in operation. When the heald frame is open, the warp thread moves towards the front of the heald, while when the shed is closed, the warp thread moves back from the heald, and the distance from back to back is the friction motion. The loom operates continuously, and the opening and closing of the loom are constantly in circulation. It is also an important link that causes warp hair to break warp. In particular, the opening height is too high, the opening parts are worn out, the motion of heald frame is unstable, the heddle wire moves up and down and swings, the loom speed is fast, and the warp thread and wool warp warp are broken.

“Six measures” to prevent wool and warp breakage

  1. Optimize raw materials according to different varieties and quality requirements. After entering the factory, the raw materials are sampled for physical and mechanical performance test, and then injected in the weft direction on the loom to make samples for the weavability and color absorption of the raw materials, which lays a foundation for the production of raw materials and the reasonable formulation of finishing, slurry and process parameters.

2, for the whole, pulp, and process guide wire parts, wool wire monitor, electrostatic eliminator, stop device, etc., to check regularly, found the problem in time. After the machine, to check again, whether the warp shaft hair silk, if there is hair silk, pick out in time, and notify the previous process, analysis of the reason.

  1. Strengthen the quality acceptance of reed and heald wire, and manage regular inspection, cleaning and maintenance.
  2. Check and repair the shedding device of the harness frame of the loom regularly to prevent the shedding parts from wearing out, the motion of the harness frame is unstable and the heald wire is swinging.
  3. Under the condition of smooth filling insertion in water-jet weaving, the opening height should be as small as possible.

6, each process to strengthen the awareness of quality. Improve the operation skills, through the broken end of the wire joint must clear the silk road, joint should be small, short, not off the knot.
