Causes Of Common Defects In Garment Fabrics

Kink yarn defects.

This situation means that some fibers in a yarn appear to be very curly and do not distinguish the direction of the fiber.

The reason for this is due to some

Compared with the drawing roller, it is too long, which causes the front and rear roller to release the fiber before and after a drawing roller has already clamped the fiber, so that the fiber will break and curl.

Kink yarn looks like a small twist in the fabric.

The color fly is woven into defects.

This refers to the presence of different colors of fiber impurities in yarns or fabrics.

Colored yarn is worn wrong.

For woven fabrics, this situation refers to the fact that the yarn dyed with loom is opposed to the color pattern and / or weave design; for warp knitted fabrics, this refers to the fact that the yarn painted by the guide rod is opposite to the pattern design.

Remove the pulp defects.

In the printing process, if the color of the storage tank is running out, it will create a blank print pattern.

Towing defects.

This is due to the pattern distortion caused by painting on the printing process.

Hard crease defects.

For knitted fabrics, this defect refers to the hard creases caused by the use of wrinkled fabrics during shrinkage control and stabilization.

Wrinkle faults.

The defect is the washboard phenomenon caused by the abnormal work of the shrink cloth.

Cover defects.

This term is usually used to describe the surface defects of fabrics, such as the number of warp and weft yarns, the prominence of patterns, and other desirable characteristics that can be obtained by changing one of the yarn systems in the two yarns.

Crease defects.

This defect refers to the creases produced by fabric folding under pressure.

Wrinkles.

This defect is referred to in dyeing or finishing work.

The visible post effect caused by folding.

Damaged defects.

This situation refers to the fact that the fabric has been damaged and can no longer be applied to a predetermined occasion.

Knife marks.

This defect refers to a narrow, swinging flower produced during the printing process due to blade breakage.

Double warp defects.

This situation means that two warp yarns appeared in the place where the fabric design originally needed only one warp.

Double weft defect.

This situation means that two weft yarns appeared in the loom shed where the fabric design originally needed only one weft.

Double faults.

For weft yarns, this condition is that the size of the yarn is two times larger than that of the normal size due to both ends of both ends of the roving, and for the warp, the ends of both ends of the roving will cause rough ends.

Tail defect.

For warp knitted fabrics, this situation means that the warp is entangled by the warp yarn, causing the warp to knit under unstable tension conditions.

Elastic streaks.

The reason for this defect is the excess tension caused by some abnormal restrictions gradually applied to many warps.

When the restrictions are removed, these too loose warp will gradually be woven into the fabric, resulting in fabric defects.

Weft faults.

This fabric defect is caused by the insertion and loosening of the weft insertion device on shuttleless looms.

And the result is.

Because the weft insertion device can not loosen the weft in time, the weft yarn will enter the main body of the device, thus causing half the weft in the width direction of the fabric.

In addition, the weft yarn loosened will be woven into the fabric immediately. In this case, the weft yarn woven into the fabric will sometimes become a cluster.

Wrinkle defects.

This defect is caused by the printing of fabric in a folded or folded state. When opening or expanding folds or creases, the patterns are usually destroyed.
