Defects such as needles, crooked corners, color patterns, and chromatic aberrations.
b. Inspect whether the internal quality of the semi-finished product, such as the height of the mouth, the width of the mouth, the horizontal drawing of the sock, the horizontal drawing of the sock body, the straight drawing, the horizontal drawing of the sock corner, the straight drawing, the weight of the semi-finished product, etc., meet the process requirements.
c. When sampling socks, after checking the sealed samples, sampling at a rate of 30%. When the defective product rate accounts for 10%, the whole batch of socks shall be inspected or treated separately.

OEM Socks Supplier in China


The method for identify raw materials is as follows:

High-quality socks surface yarns are mainly made of cotton, combed cotton, cotton, wool, and rabbit hair. These are all high-quality socks raw materials, cool and breathable in summer, and warm in winter.

A: Use a needle to pick up a yarn in the sock. Pay attention to the yarn with no elasticity. Use a lighter to burn it. The smell is pungent plastic smell, and it burns like hair. It is a large chemical fiber. Socks; there is no clumps when burning, and dust falls, the taste is the same as burning paper, they are all cotton socks.
B: In addition, if you wear cotton socks for a long time, the surface layer will fall off layer by layer. Remember that it is layer by layer, The better cotton and better sports socks perform better.
