Specifically, it is to conduct quality inspection on finished products. For example, the inspection requirements for a pair of our most common jeans are: 1. First, check whether there is any color difference, length, holes, oil stains, etc. on the overall trousers. 2. Next, conduct further inspection to see if there is uneven thread taking (0, 1, 0, 6 seam thread), skipped stitches, and whether the required number of stitches is installed every 3cm. 3. Check whether the trousers are of correct size, whether the wheat is washed, whether the trademarks are incorrectly installed, etc. In addition, some manufacturers will send special inspectors to semi-finished products to pin down the problems in the parking space to avoid a large amount of finished product repairs. This is because semi-inspection can improve efficiency.
