Six major reasons for the production of wool and broken:
1. The physical and mechanical properties of the material are not ideal, the fiber cracking strength is low, and the warp and silk holding force is poor. During the weaving process, it cannot withstand repeated conflicts between reed and heddle, resulting in fluffing or broken ends of warp and silk single fibers.
2. The thread guide of the whole and shaft processes is grooved, damaged or shaken and wrapped firmly when the thread is unwound, which damages the strength and elongation of the fiber and deteriorates the mechanical properties. When the production and processing tension exceeds the yield value of its strength and elongation, the single fiber is cracked and the thread is broken.
3. The reed and heddle of the loom are grooved and damaged, and the warp thread cannot withstand the repeated high-frequency conflicts and the hair is broken. The faster the speed of the loom, the more severe the phenomenon of hair breaking.
4. The wool monitor of the warping machine fails, allowing the wool and long knots of the material itself to escape. Perhaps the knots are too big and too long when the car stopper breaks the warp joint. The warp thread on the warp surface is tightly wrapped during weaving, resulting in unclear openings and broken ends.
5. When the loom works, the opening height of the meridians has a great influence on the meridians and the broken meridians, because when the loom opens, the elongation of the meridians is proportional to the opening height. When the opening height of the loom is large, the elongation of the meridians is large, and the excessive elongation forms the fluffing and cracking of the meridians.
6. When the loom is working, the conflict movement of the heddle has a great influence on the warp and wool breaking of the warp. When the heald frame is open, the meridians move towards the eyes of the heald, and when the shed is closed, the meridians move backward from the eyes of the heald, and the distance of this forward and backward movement is the collision stroke. The loom works continuously, opening and closing, and the meridians move back and forth in the eyes of the heald and are subject to conflict. It is also an important link in the formation of the meridian. In particular, the height of the opening is too large, the opening parts are worn, the movement of the heald frame is unstable, the heddle moves up and down, and the speed of the loom is fast.
