Here are some major woven fabric faults:
- Broken Warp or Weft Yarns: This occurs when a warp or weft yarn is broken during the weaving process. The result is a gap or hole in the fabric.
- Double Pick or Double End: This fault occurs when two picks or ends are woven into the same shed. The result is a thick, bulky area in the fabric.
- Floating Pick or End: This fault occurs when a pick or end is not properly interlaced with the other yarns in the fabric. The result is a loose yarn that floats on the surface of the fabric.
- Selvage Defects: Selvage defects can be caused by a number of factors, including incorrect tension or alignment of the warp yarns. The result is a rough or uneven edge on the fabric.
- Skipped or Missing Threads: This occurs when a warp or weft thread is missed during the weaving process. The result is a gap or hole in the fabric.
- Slubs: A slub is a thick spot in the yarn that creates a thicker area in the fabric. Slubs are often intentional in some types of fabrics, but can be considered a fault in others.
- Uneven Weave: An uneven weave can occur when the tension on the warp or weft yarns is not consistent. The result is a fabric that appears wavy or uneven.
- Uneven Dyeing: This occurs when the dye does not penetrate the fabric evenly. The result is a fabric with areas that are lighter or darker than others.
- Snags: Snags occur when a thread is caught on a rough surface, causing the yarn to pull or break. The result is a visible snag or hole in the fabric.
- Stains or Discolorations: These can be caused by a number of factors, including improper dyeing or exposure to chemicals or sunlight. The result is a fabric with visible stains or discolorations.
