12 Common defects in Knit fabrics
12 Common defects in Knit fabrics. Knit fabrics can also encounter various defects during manufacturing, which can affect the appearance, durability, and performance of the final garments.
12 Common defects in Knit fabrics. Here are some common knit fabric defects found in the garments industry:
Holes or Runs: Holes or runs in knit fabrics can occur due to yarn breakages or snags during the knitting process. These defects result in visible gaps in the fabric and can compromise its integrity.
Drop Stitches: Drop stitches happen when a stitch is missed or dropped during the knitting process. This creates a visible line or ladder-like effect in the fabric, affecting its appearance and structure.
Snags or Pulled Yarns: Similar to woven fabrics, snags occur when yarns are pulled or stretched out of place, resulting in visible loops or threads on the fabric surface. Snags can occur during knitting or handling processes.
Uneven Tension: Uneven tension in the knitting process can lead to variations in fabric density or gauge across the fabric. This can cause noticeable differences in texture or appearance within the same piece of fabric.
Fabric Distortions: Knit fabrics can experience distortions such as twisting, puckering, or curling edges. These distortions can occur due to uneven tension, improper handling, or inconsistencies in the knitting process.
Color Variation: Color variation defects occur when there are differences in color shade or intensity within the same batch of knit fabric. This can be caused by dyeing inconsistencies or uneven dye penetration.
Holes in Jacquard or Patterned Knits: In jacquard or patterned knit fabrics, defects such as holes or missing stitches in the pattern can occur, affecting the design and integrity of the fabric.
Fabric Shrinkage: Knit fabrics may shrink excessively during washing or finishing processes if not properly pre-treated or stabilized. Shrinkage can cause garments to become smaller than intended and affect their fit and shape.
Pilling: Pilling refers to the formation of small balls or clusters of fibers on the fabric surface, typically caused by friction during wear or improper finishing processes. Pilling can affect the fabric's appearance and texture.
Seam Slippage: In garments where knit fabrics are used in seams, seam slippage can occur when the fabric yarns pull apart at the seam line. This defect compromises the strength and durability of the seam.
Yarn Distortions: Yarn distortions in knit fabrics can include thick or thin areas, knots, or irregularities in yarn diameter. These defects can create visible inconsistencies in the fabric surface.
Cut Holes: Cut holes may occur during the cutting process if the fabric is not handled carefully, resulting in unintended cuts or tears in the fabric.
