Student clothing refers to the clothing worn by students. The uniform that students wear in school is called school uniform. School uniform is a common type of student uniform. The school uniform reflects the characteristics and style of students. It not only plays a certain role in clothing, but also plays an indispensable role in the field of students' thinking What are the testing ranges for student uniforms Student school uniforms, polyester school uniforms, pure cotton school uniforms, etc What are the testing contents for student uniforms Color fastness testing, strength testing, anti resistance testing, formaldehyde testing, component analysis, quality testing, pressure testing, factory testing, label testing, and other testing What are the testing items for student uniforms Formaldehyde, pH value, fiber content, color fastness, decomposable aromatic amine dyes, breaking strength, seam strength, pilling, perspective, splicing and dyeing degree, etc

The testing items for student clothing and sports clothing are relatively similar. For routine testing, BAIJIAN has launched a package service to facilitate customers to have a clear understanding of the testing items they need, while further saving costs and time.

FZ/T 73045-2013 knitted children's clothing is suitable for children aged 3 years (height 100cm) and under 14 years old who are mainly made of knitted fabric. This standard is not applicable to knitted cotton clothing and knitted down clothing. The color requirements for the project annotation of the numbered item are as follows: 1. Fiber content # 1. The name and content of each component fiber in the textile product, expressed as a percentage of the total fiber content in a certain part of the product. Any two cycles of 10 grams or more of formaldehyde in one color. Formaldehyde is a colorless gas with a pungent odor. Textiles containing formaldehyde will gradually release free formaldehyde during use, which can cause respiratory and skin inflammation through contact with the human respiratory tract and skin. It can also cause irritation to the eyes. The pH value of a 10g 3PH fabric with a uniform color refers to the residual acid and alkali content in the fabric. If various chemicals in textile printing and dyeing processing are not fully washed or neutralized, the acidity and alkalinity on the fabric are too high, exceeding the range of pH adaptation of the human skin, which can easily cause skin itching, allergies, inflammation and other diseases, and even damage the sweat glands and nervous system of the human body, affecting human health. If one or more odors, such as rain odor, high boiling range petroleum odor (such as gasoline or kerosene odor), fishy odor, or aromatic hydrocarbon odor, are detected in a 20 gram 4 color textile, it will be deemed as "odorous" and the odor category will be recorded. Any color of 30 cm * 30 cm can be decomposed into aromatic amine dyes. Decomposable aromatic amine dyes refer to dyes synthesized from carcinogenic aromatic amines, commonly known as "prohibited azo dyes". After decomposable aromatic amine dyes are made into clothes, they cannot be distinguished from the appearance of textiles and can only be detected through technical testing, and cannot be eliminated. This type of dye can cause various malignant diseases and absorb carcinogens when in contact with human skin. The degree of fading resistance to water immersion during use or processing of various types of textiles dyed or printed with a color fastness of 10 grams per square meter (excluding white). The degree of fading resistance to sweat during use or processing of various types of textiles dyed or printed with a color fastness of 30 centimeters * 30 centimeters per square meter (excluding white). The degree of fading caused by external friction during use or processing of various types of textiles with uniform color (excluding white) 30 cm * 30 cm 8 color fastness to rubbing, dyeing or printing. The force that a strong fabric with a uniform color (excluding white) of 30cm * 30cm 9 can withstand when expanding to rupture. The size change rate after washing and drying refers to the size change in the length and width direction of a textile, usually expressed as a percentage of the original size change. After washing, any one color of 3 finished products with 11% twist rate will cause distortion in the side seams or edges of the clothing, resulting in serious unevenness and deformation after wearing, thereby affecting the aesthetics and wearing effect of the clothing. The appearance quality of any color 12 after washing shall not show any visible changes such as holes, distortion, or deformation after washing, and the accessories shall not deform, discolor, rust, or fall off. The degree of fading of various types of textiles dyed or printed with 13 color fastness to soap washing during use or processing. The degree of fading of various textiles dyed or printed with a color fastness of 30 cm * 30 cm (excluding white) to light during use or processing. The degree of fading of various textiles dyed or printed in alkaline solution with a color fastness of 30 cm * 30 cm 15 to light and sweat during use or processing. The uniform color 30cm * 30cm 16 pilling fabric causes pilling and pilling on the surface of the fabric during wear due to the performance of the fabric itself and external friction, forming a section of pilling that is buried in the fibers of the fabric at one end and connected to the fabric surface at the other end. The pilling is prone to dirt and dirt accumulation, which affects the aesthetics of the fabric. The phenomenon of pilling and pilling on the surface of fabrics can occur on both natural and chemical fiber fabrics, while wool textiles, synthetic fibers, and blended fabrics are more likely to occur. The moisture permeability of any color 40 cm * 40 cm 17 refers to the water vapor mass that vertically passes through a unit area of the sample within a specified time under the specified temperature conditions on both sides of the sample. Any color 30 cm * 30 cm 18 splices fabrics with different degrees of mutual dyeing and colors together, and after washing, it is easy to cause mutual staining. Dyes usually migrate from dark to light areas, causing severe staining in light areas, Due to inconsistencies in fiber composition and dyeing methods, when combining dark and dark colors, such as bright red and purple, staining can also occur, affecting the appearance of textiles. A piece (dark and light color splicing) of 30 cm * 30 cm 19 children's clothing rope and strap safety requirements. The end of the strap, functional rope, and belt should not be tied or three-dimensional decorative materials should be used to prevent wear and tear. It is recommended to use heat sealing, knotting, overlapping, or folding methods. A metal needle with 20 residual metal needles in any one color of one finished product. Any one color certification date: 3-5 working days for the above project testing, and 4 working days for the GB18401 project
