Summer vacation is also a time of preparation for a large purchase of student supplies. The quality of school uniforms is closely related to the health and safety of students, both parents and society are particularly concerned about this, compared to the "appearance level", the "connotation" of school uniforms is more important.

The reporter learned from a number of fabric testing institutions in Keqiao that in recent days, many school uniform fabric operators in the textile city market have improved their self-quality awareness and actively sent fabrics for inspection, and the proportion of school uniform fabrics tested by relevant institutions has gradually increased.

So, how to distinguish the quality of school uniforms? In order to ensure that children wear healthy and safe school uniforms, what industry standards have been introduced by the state? How should consumers choose to buy? Han Yanyan, member of the Standardization Technical Committee of China Clothing Association, expert member of the Quality Professional Committee of Zhejiang Consumer Rights and Interests Protection Committee, and manager of the Marketing Department of Zhejiang Hengxiang Testing Technology Service Co., Ltd. gave suggestions from multiple perspectives.

In the business of testing institutions, in addition to GB/T 31888-2015 "School uniforms for primary and secondary school students", there are GB/T 22854-2009 "Knitted student clothing", GB/T 22854-2009 "Knitted student clothing" and some local standards. Among them, GB/T 31888-2015 "primary and secondary School students' uniform" has the highest standard and the most stringent indicator requirements, which is most in line with the current quality demands of parents and schools for student clothing, and is more recommended.

From a professional point of view, Han Yanyan also gave consumers some "forget to hear and ask" advice. First of all, while choosing a stable and reliable quality brand manufacturer, the purchase should also carefully check the packaging and tag of the school uniform to see if there is a product name, product model, fiber composition and content, producer name, address, safety category, implementation standards, washing methods, etc., to ensure that the clothes are complete. Secondly, try to choose the school uniform with a high amount of cotton light fabrics, cotton fabrics are comfortable and soft, relatively good permeability, suitable for primary and middle school students who are growing bodies, light fabrics can avoid potential problems caused by various industrial dyes. Finally, pay attention to the structural safety of school uniforms, in view of structural safety problems, special attention should be paid to the rope belt of school uniforms, residual metal needles, accessories sharpness, etc.
