1.Depends on the size, shape and skin feel of the socks. How about the workmanship of the stitching position and the correction of the thread end, etc.
2. Observe the contractility of the end position of the opening. In internal quality inspection, the mouth is generally opened and contracted, and it is observed whether it is well recovered. Of course, you should also pay attention to whether the contraction of the lower mouth is too much, otherwise you will feel restrained when wearing and using it.
3. Is the fine stitching process. When observing, you can pull it down slightly with your hands, not too large, to see if the stitched stitches are clearly visible.
4.look at the glue material at the bottom, whether the layout is uniform, and how well the ground is.
5.The elasticity of the sock mouth should be appropriate, whether the color of the suture is serious and obvious, and whether the thread end is clean and tidy. Whether the non-slip dispensing is evenly distributed is to determine whether the sock is qualified and fine.
