Defects of Woven Fabric | Texhour
the defects of woven fabrics are slub, grain, on-grain, off-grain, reed mark, flat, broken, slack, coarse, bowed, skewed and they are explained in these post.
Defects of Woven Fabric
The position of warp yarns relative to filling yarns in a fabric
|On-grain||Warp yarns lie parallel to each other (lengthwise) & weft yarns lie parallel to each other (crosswise). Warp & weft yarns lie perpendicular to each other.|
|Off-grain||Lowers fabric quality, the fabric does not drape properly, Printed designs are not straight.|
Filling yarn is at an angle other than 90 degrees to warp yarns.
|Bowed fabric||Filling yarns dip in the center of the fabric.|
|Yarn contamination or Fly||Floating fibers of different colors or different content enmeshed in the yarn.|
A slub caused by uneven spinning or by waste caught during spinning causes a weak spot in the yarn. Could result in a hole in the fabric.
Reed marks due to the improper spacing of the warp yarns.
|Barre marks||Barre marks due yarn count variation or faulty loom functioning.|
|Coarse End or Pick||A warp or weft yarn having a larger diameter or more plies than the body of the fabric.|
|Chafe||An area where the fabric has been damaged by abrasion or friction.|
|Flat||Two or more threads weaved as one and not meant to be a feature of the weave.|
Broken or missing ends or picks.
Slack or tight ends or picks.
