喷水织造“毛丝”和“断经”六原因及六对策/Six reasons and six countermeasures for water-jet weaving "wool" and "broken"
First, the "six reasons" for producing wool and menstruation
1. The physical and mechanical properties of the raw materials are not ideal, the fiber breaking strength is low, and the warp cohesion is poor. In the weaving process, the steel shovel and the healds are not repeatedly rubbed, resulting in the warp single fiber fluffing or breaking.
2. Warping, and shaft process yarn guides are grooved, damaged or warp when they are unwound, and the fiber strength and elongation are damaged, and the mechanical properties are deteriorated. When the production and processing tension exceeds its strength and elongation When the yield value is long, the single fiber breaks and breaks.
3. Looms steel shovel, healds grooving, damage, warp can not withstand repeated high frequency friction and hair break. The faster the speed of the loom, the more severe the warp phenomenon.
4. The warping machine's hairline monitor fails, so that the raw material's own wool and long knots escape or the blocker is too big and too long when the joint is broken. When the weaving, the warp and warp threads are entangled, causing the opening to be unclear. Pull the broken head.
5. The operation of the loom, the opening height of the warp yarn has a great influence on the warp and the warp, because the elongation of the warp is proportional to the height of the opening when the loom is opened, and the opening height of the loom is large, then the warp of the loom The elongation is large, and the excessive elongation causes the hair to fluff and break.
6. When the loom is running, the frictional stroke of the heald has a great influence on the warp of the warp. When the heald frame is opened, the warp yarn moves toward the front of the eye, and when the shed is closed, the warp yarn moves backward from the eye. This distance of movement back and forth is the friction stroke. The loom continuously runs, the opening and the closed loop continue to circulate, and the warp yarn is continuously reciprocated and rubbed in the eye. It is also an important link that causes warfare. In particular, the opening height is too large, the opening parts are worn, the heald frame movement is unstable, the healds are moving up and down, the loom speed is fast, and the warp yarn passing through the hair is more serious.
Second, the "six measures" to prevent hairline and menstruation
1. The raw materials are preferred according to different varieties and quality requirements. After the raw materials enter the factory, the samples are first tested for physical and mechanical properties, and then sprayed onto the weaving machine in the weft direction to make the raw materials woven and absorb the color samples, which lays the foundation for the raw materials to be put into production and rationally formulate the whole, pulp and process parameters.
2. For the whole, pulp, and process guide wire components, yarn monitors, static eliminators, broken heads and other devices, it is necessary to check regularly and find problems in time. After starting the machine, you should check it again. There is no wool in the warp beam. If there is wool, pick it out in time and inform the previous process to analyze the reason.
3. Strengthen the quality inspection of steel shovel and heald, and do regular management such as inspection, cleaning and maintenance.
4. Regularly inspect and refurbish the opening device of the weaving machine heald frame to prevent the opening parts from being worn, the heald frame movement is unstable, and the healds are undulating.
5. Spray water weaving in the case of ensuring smooth weft insertion, the height of the opening should be as small as possible.
6. The various process blockers to enhance quality awareness. Improve the operation skills, the wire break joint must be clear the silk road, the joint is small, short, and does not detach.
