Factors affecting polyester webbing.
1. Reasons for bending belt:
1. Uneven wear of steel buckle 2. Uneven yarn drawing on pan head 3. Wrong orientation of steel buckle 4. Incorrect yarn splicing method. Preventive measures:
1. The steel buckle piercing method must follow the regular piercing method, one or two sets of piercing.
2. Pull off the larger and looser side until it is the same level as the other side or 1-5 turns less.
3. The steel buckle is generally separated from the knitting needles, and there is only a gap between the steel buckle.
4. According to the demand of shoe material webbing, it is divided into base layer connection, or divided, left and right connection, generally divided into upper and lower, if there are more than two methods or textures on a belt, it must be separated.
2. Reasons for the formation of waves:
1. The steel buckle is not evenly worn, too much yarn is worn at both ends, and too little is worn at the center.
2. The steel buckle is worn too large and the weft is pulled too tightly.
3. The yarn drawn on the pan is not flat, the two ends are tight, and the center is too loose.
4. The method of splicing yarn is wrong, and the balance of falling pressure is not good.
Third, the reasons for the poor needle edge:
1. Uneven thickness of weft yarn:
2. The knitting needle is wrong, too long or too short. 3. The pan head is not normal, sometimes tight and sometimes loose.
4. The weft wheel is not round and deformed.
5. The fixed needles are worn out.
4. Reasons for fluffing:
1. The needle edge is fluffing.
2. The edge of the cloth is fluffed
3. The surface of the webbing is fluffy
1. The needle plates of some garment knitting factories have been used for a long time and have been damaged. Changed the new needle plate; the knitting needle is damaged, replace the new knitting needle; press the belt pressure plate too tightly, relax the belt pressure plate; if the weft yarn is not finished, adjust the interval between the weft needle and the knitting needle so that the weft yarn can be finished. 2. Hang the steel buckle for the weft, and put the weft into the weft rod; if the steel buckle is damaged, replace another steel buckle; the material itself has hairs, if it is partly fluffed, replace the fluffed ones, if too much fluffing, finish The goods will do a full-view belt in the future.
3. If the weft needle is damaged, change one, or hit it with gauze; if the steel buckle is damaged, hit it with gauze, or replace the steel buckle; the brown silk piece is damaged or the stop piece is damaged, and the new one is replaced.
