School uniform is the uniform worn by school students (children, primary school students and middle school students). Tracing back to its origin, it is not to show the order in the school or in the educational places, but to show the significance that there are some differences between the school and the general society. The biggest difference is that the uniforms in general society are only needed to be worn at work. On the contrary, school uniforms will be worn on the way to school. One of the functions of school uniform design is to distinguish students who wear different school uniforms from different schools. There are two benefits to this effect. One is for the school to improve the management of students, the other is for students to establish their own identity and enhance the sense of belonging. The new design, Abolishment and change of school uniform are of great significance to keep the unity within the school and to maintain the school order rules

        There are three kinds of school uniform: synthetic fabric, warp knitted fabric and cotton fabric: synthetic fabric is a popular fabric for several years. Due to its unique style, color diversity, easy washing and quick drying, easy care and other advantages, it is widely used in school uniform customization industry, and its products include Huayao, Taslon, Cardan velvet, washed velvet, etc.; warp knitted fabric is also widely used because of the fabric of warp knitted fabric It is elastic, comfortable and smooth, easy to stretch and stretch. It is popular among students. The products include golden velvet, striped velvet, polyester covered cotton, etc.; the cotton containing fabrics have the advantages of soft handle, strong sweat absorption, and many kinds of patterns and colors, which are suitable for school uniforms of sports types. The products include brocade cotton cloth, polyester cotton cloth, etc.

        The school uniform with cotton fabric is selected because of the following characteristics: 

        1. Moisture absorption: cotton fiber has good moisture absorption. Under normal circumstances, the fiber can absorb water from the surrounding atmosphere, and its moisture content is 8-10%. Therefore, it contacts with human skin and makes people feel soft but not stiff. If the humidity of cotton cloth increases and the surrounding temperature is high, the water content in the fiber will evaporate and disperse, so that the fabric can maintain water balance and make people feel comfortable. 

        2. Moisture retention: because cotton fiber is a poor conductor of heat and electricity, its heat conductivity is very low, and because of its porous and high elasticity, a large amount of air can be accumulated between the fibers, and the air is a poor conductor of heat and electricity. Therefore, pure cotton fiber textiles have good moisture retention, and wearing pure cotton clothing makes people feel warm. 

        3. Heat resistance: pure cotton fabric has good heat resistance. When the temperature is below 110 ℃, it will only cause water evaporation on the fabric and will not damage the fiber. Therefore, the wearing, washing, printing and dyeing of pure cotton fabric at room temperature have no influence on the fabric, thus improving the washing and wear resistance of pure cotton fabric. 

        4. Alkali resistance: cotton fiber has a greater resistance to alkali. In alkali solution, cotton fiber will not be damaged. This property is conducive to washing, disinfecting and removing impurities after taking. At the same time, it can also dye, print and process pure cotton textiles to produce more new cotton varieties. 

        5. Hygiene: cotton fiber is a natural fiber, its main component is cellulose, and a small amount of waxy substances and nitrogen-containing substances and pectin. The pure cotton fabric has been inspected and practiced in many aspects. It has no irritation and negative effect when it contacts with skin. It is good for human body to wear it for a long time and has good sanitary performance.
