Textile fabrics cause defects

Yokohama (Barre)

For knitted fabrics, this defect is characterized by the appearance of uneven patterns in the course of the fabric or in the transverse direction of the fabric. Uneven yarns, uneven Yarn tension, and different dye affinities of the yarn may be the reason for this.

Bad place (BadPlace)

This is a very convenient term for fabric defects that are difficult to describe in words. This term is often used to describe where fabric weaving is severely damaged.

Bias (reference weft)

For woven fabrics, this defect refers to where the weft and warp yarns are skewed; for knitted fabrics, this refers to where the fabric course is skewed from the longitudinal direction of the fabric.

BirdseyeDefect

For knitted fabrics, this refers to occasionally irregularly occurring tucks that are opposite to the fabric design.

Bow arc

For woven fabrics, this means that the weft yarns are located in the width direction of the fabric in an arc; for knitted fabrics, this means that the courses are arcuately oriented in the width direction of the fabric.

Broken End

This type of defect refers to the place where the warp yarn is broken and repaired. Its common feature is that the broken piece that is woven into the fabric can be seen.

Patterned é”™ (BrokenColPattern)

For woven fabrics, this refers to the discontinuity of the pattern, the error in drawing a color pattern with the looms, or the refilling of the image after the looms are broken. Incorrect settings can lead to such defects; for knitted fabrics, this is caused by a bobbin change.

Brokenpick

This situation refers to the lack of weft yarns over a partial width of the fabric due to breakage of the weft yarns.

Bruise (refer to the gusset) refers to the fact that the yarn being woven or the fabric that has been woven is subject to wear, resulting in loss of orientation and distortion of the fabric.

Spotted ç–µ (Burlmark)

This is a deformation caused by an excess of certain materials, including roving lines, waste, and floating yarns that are being removed with a repair tool.

吊边疵 (Buttonholeselvage)

This is a fabric weave defect, and the excessive tension accumulated on the loom shuttle before the weft is replaced is the cause of this defect. This tension tends to limit the correct shedding and staggering of the weft yarns, creating a shackle similar to the buttonhole.

Abrasive yarn (ChafedYarn)

Such defects refer to yarns that are subject to wear, which, after being worn, can cause the fibers to lose their sense of direction and distort the yarn. Such defects will affect the colorability of the yarn and often result in the creation of radial streaks or weft streaks.

Chopped Weilling

This defect refers to the imbalance phenomenon in the direction of the weft yarn, which is characterized by the presence of an obvious or neat pattern which is caused by the eccentric behavior of the drawing roller.

Holemark (Clipmark)

This defect refers to the place on the fabric that has not been dyed. This defect is caused by the metal clip caught on the edge of the fabric.

These clips are used to avoid or correct the hem of the fabric when it is folded during dyeing.

CoarseEnd

This situation means that the diameter of one warp yarn is significantly larger than the diameter of the normal warp yarn of the fabric.

CoarsePick

This situation means that the diameter of one weft yarn is significantly larger than the diameter of the normal weft yarn of the fabric.

Coarse Yarn

This situation means that the diameter of one of the yarns is significantly larger than the diameter of the normal yarn of the fabric.

Wrinkled Fabric (CockledFabric)

For knit fabrics, such defects refer to those wrinkled, shrunken or embossed fabrics that cannot be laid flat on the cutting table. This phenomenon may be caused by irregular twisting of the yarn, or because the yarn is not tensioned during the knitting process, or because the yarn in the fabric is not uniformly responsive in the finishing process.

Twisted yarn C (CockledYarn)

This situation means that some of the fibers in a yarn appear to be very curled and do not distinguish the direction of the fibers. The reason for this is that some of the yarn fibers are too long relative to the drawing roll, causing the drawing roller to clamp the fiber before the previous drawing roll releases the fiber, thus Will cause the fiber to break and curl. The twisted yarn looks like a tiny flaw in the fabric.

Colored fly weaving ç–µ (ColFly)

This situation refers to the appearance of fibrous impurities of different colors in the yarn or fabric.

Color yarn worn by ColMisdraw

For woven fabrics, this refers to the fact that the colored yarns drawn by the looms are opposite to the colored and/or textured designs; for warp knitted fabrics, this refers to The color yarn drawn by the guide bar is opposite to the pattern design.

Desizing pulp (ColOut)

During the printing process, if the color paste in the storage tank is used up, it will cause a blank pattern of the printed pattern.

Tow pulp (ColSmear)

This situation is due to the deformation of the pattern caused by the application of the pigment during the printing process.

Hard Crease (CompactCrease)

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

Crugation (refer to pre-shrinking wrinkles)

This kind of defect is caused by the thick plate of the pre-shrinking finishing machine which is not working normally.

The term cover is often used to describe the surface characteristic defects of fabrics, such as the number of warp and weft yarns, the pattern protrusion, and others that can be obtained by changing one of the two yarn systems. Expected characteristics.

Crease This type of defect refers to the crease that the fabric folds under pressure.

Wrinkle flower bud (CreaseStreak)

This defect refers to the visible aftereffect caused by the folding of the fabric during the dyeing or finishing work.

Damaged situation refers to the fact that the fabric has been damaged and can no longer be used in the intended place.

Knife Scratch (DoctStreak)

This defect refers to a narrow, oscillating strip that is created by the scraper during the printing process.

Double warp yarn (DoubleEnd)

This situation refers to the appearance of two warp yarns where the fabric design originally only requires one warp yarn.

Double weft yarn (DoublePick)

This situation refers to the presence of two weft yarns at the weaving machine woven end where the fabric design originally only requires one weft.

For double weft (Doubling), this case means that the size of the weft yarn is twice as large as the normal size because both ends of the roving hit the end of the spun yarn at the same time; for the warp yarn, due to the roving Both ends of the yarn hitting the end of the spun yarn at the same time will result in roughening.

Trailing ) (DraggingEnd)

For warp knit fabrics, this refers to the fact that the warp yarns are entangled by the warp yarns, resulting in the warp yarns being knitted under unstable tension conditions.

Elastic strips (Drawback)

The reason for this defect is the excessive tension caused by some abnormal restrictions that are gradually applied to many warp yarns. When the restriction is removed, these excessively slack warp yarns are gradually woven into the fabric, resulting in fabric defects.

Low weft yarn (DroppedPick)

This fabric defect is caused by the fact that the weft insertion device on the shuttleless loom cannot clamp and loosen the weft yarn in time. Since the weft insertion device cannot release the weft yarn in time, the weft yarn enters the main body of the device, thereby causing half of the weft in the width direction of the fabric. In addition, since the loosened weft yarn is immediately woven into the fabric, in this case, the weft yarn woven into the fabric sometimes becomes tangled.

Dyed flower bud (DyeStreak)

This is a dye-related stripe defect, which depends mainly on the application of the dye on the fabric or the absorption of the dye by the fabric.

Missing ç–µ (EndOut)

This situation refers to the lack of warp yarns.

Weft strips (Fillingb)

This situation refers to a visually visible streak in the width direction of the fabric. The difference in the physical or chemical properties of the weft yarn is the direct cause of this defect.

FilingFloats (refer to weft yarn, upper jumper, and lower jumper)

This situation means that the weft yarns are not interlaced with the warp yarns, but are stretched freely above or below them.

Fine warp yarn (FineEnd)

This defect means that the diameter of a certain or some warp yarns is significantly smaller than the diameter of the normal warp yarns of the fabric.

Fine Yarn For knitted fabrics, this defect means that the diameter of a certain or some of the yarns is significantly smaller than the diameter of the normal yarn of the fabric, which usually results in a fabric course or Thin line-like cracks appear in the transverse direction of the fabric.
