Question 2: What fabric is used for school uniform pants to make pure cotton?
Question 3: What is the 50-point chemical fiber fabric of this kind of school uniform pants?
Question 4: What are the ingredients of most school uniform pants in China at present? At present, the compulsory national standards for the quality of school uniforms mainly include GB 1840 1-2003 National General Safety Technical Specification for Textile Products and GB 5296.4- 1998 User Manual for Consumer Goods. , and some related standards. The key product inspection items specified in the standard include school uniform logo, fiber content, formaldehyde content, pH value, banned azo dyes, color fastness to water, dry rubbing, wet rubbing, acid and alkali perspiration, washing, washing size change rate and pants seam strength. In addition, the standard classifies the uses of products by combining the main indicators related to safety, such as formaldehyde content and pH value, and limits the formaldehyde content and pH value of different categories. There is a question of 1 The problem of unqualified product identification is widespread. Because school uniforms are generally ordered by schools rather than students and manufacturers, their products do not need to be sold in the market, and most manufacturers have not marked them according to the standard requirements, which is misleading and deceptive to consumers. Judging from the results of spot checks organized in the past two years, the problem of unqualified product identification accounts for a large proportion in the spot checks, and even some school uniform products do not have any correctly marked identification content at all, which reflects that school uniform producers and sellers have a serious lack of understanding of the importance of identification, lack initiative and consciousness in strictly implementing standards, and generally do not meet the requirements of GB5296.4- 1998 "Instructions for the Use of Consumer Goods, Textiles and Clothing" and corresponding product standards. 2. The problem of excessive formaldehyde content is outstanding. In previous years, the fabrics used in school uniforms were mostly pure cotton, polyester cotton or pure chemical fiber. The main problem of cotton fabric clothing is that it is easy to shrink, but it does not affect the safety of use. However, there are some problems in polyester fabric clothing, such as no sweat absorption, poor air permeability and easy formaldehyde content exceeding the standard. Excessive formaldehyde content will have a great impact on the safety of use. 3. Some fabrics used in school uniforms are not up to standard. Due to the poor quality awareness of production enterprises, and in order to pursue their own economic interests and achieve the goal of low cost and high profit, some enterprises use cheap and light clothing fabrics in the production process, which leads to the underwear looming in the process of wearing its products, and was once passed down as a transparent school uniform. Tips for purchasing: First, when ordering school uniform products, schools should buy products from regular and qualified manufacturers. When signing a school uniform purchase contract with a school uniform manufacturer, the quality requirements of school uniforms, especially the internal quality requirements, should be clearly and carefully written into the contract terms, which is not only a constraint and requirement for the enterprise, but also a powerful basis for dealing with quality problems. The second is to carefully check and accept school uniforms. In addition to the appearance and style, the quality acceptance of school uniforms should also pay attention to acceptance. We can ask the production enterprises to provide the product inspection/testing reports (including product safety indicators and product wearability indicators) issued by authoritative organizations, or ask professional fiber inspection institutions to conduct random inspections. The third is to remind students that the newly bought school uniforms should be thoroughly cleaned before use. Because washing can improve the pH value of the product, better protect human skin, wash away the residual free formaldehyde in the fabric, and at the same time wash away all or most of the "floating color" on the product, reducing the possibility of color fastness exceeding the standard. Fourth, if students feel red, swollen and itchy after wearing school uniforms, they should report the situation to the school in time and deal with it. If there are serious quality problems, we should complain to the relevant departments and handle them through administrative supervision.
Question 5: What is a school uniform? There are three kinds of school uniforms: synthetic fabrics, warp-knitted fabrics and cotton fabrics. Synthetic fiber fabric is a popular fabric in recent years. Because of its unique style, diverse colors, easy washing and quick drying, easy care and other advantages, it is widely used in the school uniform customization industry. Products include Huayao, Taslong, Karting cashmere, washed cashmere and so on. Warp knitted fabrics are also widely used. Because of their elasticity, comfort, smoothness, flexibility and fit, they are very popular with students. Products are gold velvet, striped velvet, polyester cotton and so on; Cotton-containing fabrics have the advantages of soft touch, strong sweat absorption and various colors, and are suitable for custom-made sports school uniforms. Products include brocade cotton cloth, polyester cotton cloth and so on. The school uniform is made of cotton fabric, because this school uniform has the following characteristics: 1, hygroscopicity: cotton fiber has good hygroscopicity. Under normal circumstances, fiber can absorb water from the surrounding atmosphere, and its water content is 8- 10%, so it contacts with human skin, making people feel soft but not stiff. If the humidity of cotton cloth increases and the surrounding temperature is higher, all the water contained in the fiber will evaporate and disperse, so that the fabric can keep water balance and make people feel comfortable. 2. Moisture retention: Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can accumulate between fibers, and air is a poor conductor of heat and electricity, so cotton fiber textiles have good moisture retention, and wearing cotton clothes makes people feel warm. 3. Heat resistance: pure cotton fabric has good heat resistance. When the temperature is lower than 1 10℃, only the moisture on the fabric will evaporate without damaging the fiber. Therefore, the pure cotton fabric has no influence on the wearing, washing, printing and dyeing of the fabric at room temperature, thus improving the washing resistance and wear resistance of the pure cotton fabric. 4. Alkali resistance: Cotton fiber has strong alkali resistance. Cotton fiber will not be damaged when it is in alkaline solution. This property is beneficial to washing pollution and disinfecting impurities after taking. At the same time, cotton textiles can be dyed, printed and processed to produce more new cotton varieties. 5. Hygiene: Cotton fiber is a kind of natural fiber, and its main component is cellulose, with a small amount of waxy substances, nitrogen and pectin. After many tests and practices, pure cotton fabrics have no * * * and negative effects when in contact with skin. Long-term wear is beneficial and harmless to human body, and has good sanitary performance.
