Causes And Elimination Methods Of Rotten Edges And Burrs Of Garment Fabrics

Rotten edges.

The first category is big.

The cause of formation is the NEP impurity on the weft yarn, especially the large impurities on the middle and fine yarn, and the details produced by the spinning and spinning of the spun yarn, which is caused by the collision of the weft winding air ring, resulting in unexpected resistance.

In the weft cavity, there is a waste wire, which is released from the small eye of the weft head due to the impact of the shuttle, blocking the shuttle's riding wire or the porcelain eye passage, resulting in the obstruction of the weft yarn and the increase of tension.

When the loom is wiped, the flying flowers fall into the porcelain eye of the shuttle so that the weft yarn can not expand smoothly and increase the unexpected tension.

Poor matching of shuttle pipe, different center of the shuttle, uneven height of spindle core, high and low core of shuttle core, wear of weft hole, all will make the tension of weft yarn unevenness seriously unevenness.

Elimination method.

To improve the quality of weft yarn, according to the different weaving types, the specific requirements of raw yarn neps impurities are put forward.

The weft hole of the weft hole should be solved. The weaving workshop should be combined with the regular repair of the weft pipe to eliminate it.

When cleaning looms, the shuttles should be covered with cover cloth to prevent flying flowers from falling into and blocking the shuttle's porcelain eye.

Do the matching work of shuttle and pipe.

The causes of the second kinds of small rotten edges.

The side support is not enough to extend the amplitude, while the side support needling force is insufficient, and the side yarn is not well controlled.

Especially when weft yarn is gradually rewinding from full yarn to small yarn, it is more prominent.

The middle and special weave fabric with high shrinkage ratio of warp and weft yarn is too small on the side and side yarns, or the side yarn itself is worn wrong, so it can not withstand the severe friction of the reed during beating up. It will cause broken edges and small rotten edges.

When the shuttles are full, if the warp tension is too high or the tension difference between the sides of the warp is very different, the larger side of the tension will cause the weft yarn with high tensile force to stretch out with the edge of the reed gear when it hits the weft.

Elimination method.

Carefully check the state of the spear rollers and correct the position of the side brace, which is in line with the technological requirements.

The position of the reed should be corrected, especially to prevent the upper warp from being pressed by the reed cap when the shuttles are full, and the unexpected tension of the whole warp and side yarns will be affected.

The hoist should meet the technological requirements.

In the normal operation of the loom, the reed should not touch the side brace, and the bumper should not touch the stop button to prevent broken edges and small rotten edges.

Causes of formation.

Side support scissors failed, Osa Mi cut into the fabric mouth.

The weft of the shuttle is interrupted at the shuttles.

Using the probe inducing shuttle device, the safety yarn on the weft pipe is replaced by the shuttle in the end when the shuttle is replaced, and the other end is still in the weaving port.

When the weft is cut by the side scissors, the tail yarn remains on the shuttle board. Due to the movement of the shuttle, the yarn tail will be brought into the weaving mouth every few shuttle, thus forming a beard like fringe.

Elimination method.

The side supporting scissors are well matched and installed correctly.

Technical improvement.

Reduce the method of making the edge of shuttle yarn.

A: front rail is fitted with steel wire or brush.

Rubber band is installed on the B library.

C brush brush on foot of shuttuto.

Slotting on D shuttles.

Reduce the method of making the edge of shuttle yarn.

A slotting of shuttle box floor.

B fan brake lever to install brush.

C reeds are fitted with brush.

The shape of defects on cloth surface can be divided into kinks, weft, warp and weft.

The common causes of the four types of weft shrinkage are the causes, and the quality of the original yarn is poor.

The twist of the weft is too high.

The moisture regain of weft yarn is too low.

Poor shuttle function.

The shuttle is in poor condition.

Poor articulation.

Eliminate the method to improve the quality of the original yarn.

Stabilize weft twist.

Strengthen loom maintenance.

Increase the weft tension of the shuttle properly.
