In garment factories it very common that the garment quality inspectors are also responsible for fabric inspection. I experienced it many times that there is no adequate training and tools provided to these inspectors. The best and efficient way to train the inspectors is to provide the images of defect and the defect classification. This will help them to identify and classify the defects as per the required standards.
This article provides a list of defects, images and defect classification. You can provide it to your quality and fabric team as a practical tool to identify defects during the inspection.
