Students' clothing is related to the youth group and has relations with thousands of families. The quality of products has been deeply concerned by the society.

According to the introduction, the items of spot checks are color fastness, pH value, strength of post crotch joints, fiber content and logo.

It is reported that the main reasons for the failure of products are in the following three aspects:

First, the production enterprises in pursuit of profit maximization, choose some fabrics that are not in good quality in the small printing and dyeing factories, and this kind of fabric lacks neutralization and cleaning procedures, resulting in more chemical substances remaining in the fabrics, which can cause damage to the skin.

The two is that a few enterprises have poor quality consciousness, thick needle and big code, and not enough sewing, resulting in insufficient strength of post crotch joints.

Three, some enterprises are buying cheap fabrics with low cotton content, posing as cotton fabrics with higher cotton content or not marking fiber content on the labels.

Liaoning quality supervision department has also announced the list of 20 enterprises that produce unqualified student clothing (summer wear) for Shenyang Wen Han Clothing Co., Ltd.
