Technical Terms For Various Fabric Defects

Crotch defect: Yes. Knitted fabric This defect is characterized by uneven pattern patterns on the side or side of the fabric. This may be due to uneven yarn, uneven yarn tension and different dye affinity of yarns. Bad: it's a very convenient term for fabric defects that are difficult to describe with language. This term is usually used to describe where fabric weave is seriously damaged.

Breakage defect: this defect refers to the place where the warp is broken and repaired. Its common feature is that it can see the broken ends woven into the fabric. Pattern mismatch: for woven fabrics, this situation refers to the discontinuity of patterns. Errors occur when using a loom thread to depict color patterns or repair the looms when the weft breaks. Incorrect rearrangement of image filling chains may result in this defect; for knitted fabrics, this situation is caused by the error of shuttle cartridge.

Twill defect: Yes. woven fabric This defect refers to the size deviation of weft yarns and warp yarns; for knitted fabrics, this refers to the longitudinal skew of fabric rows and fabrics. Bird eye pattern defects: for knitted fabrics, this refers to the occasional irregular ring structure that is contrary to fabric design. Arched arc: for woven fabrics, this refers to the width of the weft yarns in the way of arc. For knitted fabrics, this refers to the horizontal alignment of the coil in the width direction of the fabric.

Broken weft: This refers to the lack of weft yarns on the width of the fabric due to the breakage of the weft. Scratch: (refer to side blemished): This refers to the fact that the yarn is losing its sense of direction due to the weave of the weaved yarn or the fabric that has been knitted, and the appearance of the fabric is distorted. Spotted blemished: This is a distortion caused by excessive substances, including woolen yarn, waste, and the floating veil that is being removed with repair tools. Hanging side defect: This is a fabric selvedge defect. The excessive tension accumulated on the loom shuttle before the replacement of weft yarn is the cause of this defect. This tension often limits the correct abscission and interlacing of weft weft, resulting in a defect similar to buttonholes.

Scrape yarn: this defect refers to the worn yarn, which will cause the fiber to lose its sense of direction and distort the yarn after being worn. This defect will affect the colourability of yarns, and often lead to radial streaks or weft striations. Fragmented yarns: this defect refers to the imbalance in the direction of weft, which is characterized by an obvious or neat pattern, which is caused by the eccentric behavior of the drawing roller. Hole defect: this defect refers to the place where the fabric is not dyed. The defect is caused by a small metal clip on the edge of the fabric. These small clips are used to avoid or modify the selvage of the fabric when it is folded during dyeing. Coarse warp: this condition means that the diameter of a warp is much larger than that of the normal warp.

Coarse weft: this condition means that the diameter of a weft yarn is much larger than the normal weft diameter of the fabric. Coarse yarn defects: This refers to the diameter of a yarn that is significantly larger than that of the normal yarn. Wrinkle fabric defects: for knitted fabrics, such defects are those wrinkled, wrinkled or raised fabrics that can not be leveled on the cutting table. The reason for this phenomenon may be due to irregular twisting of yarn, or possibly due to irregular yarn. yarn The uneven tension in the knitting process may also be due to the uneven reaction of the yarns in the finishing process.
