FABRIC FAULTS IN WEAVING

FABRIC FAULTS – Weaving is the intersection of  warp and weft, which cross and interlace at right angles to each other. The lengthwise yarns are known as warp yarns and width wise yarns are known as weft or filling yarns and the fabric produced is known as woven fabric. So, making a weaved fabric involves lots of complexities and also many faults.

Fabric faults are the defects or faults that occur during either these two functions. These defects vary from minor to major. As the name suggests, Minor defects can be ignored sometimes and are not so visible, a  defect that would not cause the product to be termed a second either because of severity or location but on the other side, major defects are clearly visible and can be easily bearable, a defect that, if conspicuous on the finished product, would cause the item to be a second. Often inspectors are given the responsibility of inspecting finished garments without adequate training in fabric defects and their causes. The ultimate solution, of course, is to provide actual examples or photographs of both major and minor defects.

If a fabric has many faults then companies tend to reject the material resulting in a loss for the production companies. To avoid this rejection, the production of good quality fabrics becomes a necessity.
