Introduction:
We know that, fabric is the main raw material in the manufacturing process of garments. For that reason Knitted fabric manufacturer always try to produce their fabric defects free, but several defects may occur in the products process. There are different types of defects found in knitted fabric, but the defects of knitted fabric is less than woven fabric. I would like to discuss about the major defects of knitted fabric.
Major Defects of Knit Fabric:
After the manufacturing process of knitted fabric there following major defects are occurring which are such as like skewed or bias, barre, bird’s eye, bowing, broken color pattern, dropped Stitches, end out, hole, knots, missing yarn, mixed yarn etc. Here given any major defects of knitted fabric are as follows-
Kitted Fabric Defects
| S/L | Defects | Explanation |
| 01 | Skewed or Bias | Courses are not square with wale lines. |
| 02 | Barrie | Caused by mixing yarn on feed into machine. Fabric will appear to have horizontal streaks. |
| 03 | Birdseye | Caused by unintentional tucking from malfunctioning needle. Usually two small distorted stitches, side by side. |
| 04 | Bowing | Usually caused by finishing. The course lines lie in an arc across fabric width. |
| 05 | Broken Color Pattern | Caused by colored yarn out of place on frame. |
| 06 | Broken Color Pattern | Caused by broken or damaged needle, resulting in holes or missed stitches. |
| 07 | End Out | Caused by knitting machine continuing to run with a missing end on Warp Knits. |
| 08 | Hole | Caused by a broken needle. |
| 09 | Knots | Caused by tying cones of yarns together. |
| 10 | Missing Yarn | Caused by one end of yarn missing from feed & machine continuing to run. |
| 11 | Mixed Yarn | Caused by wrong fiber yarn or wrong size yarn being placed on warp. Results in thick end or different color if fibers have a different affinity for dye. |
