There are many materials used for belts, usually leather belts, most of which are made of leather, especially animal leather. Animal leather is a natural leather, also known as genuine leather, which is tanned and processed from various animal skins (raw leather) to produce leather materials with various characteristics, strength, feel, colors, patterns, such as cow leather, sheep leather, pig leather, etc. Synthetic leather and synthetic leather are made from textile or non-woven fabric substrates, respectively coated with polyurethane and treated with special foaming. Their surface feel is similar to genuine leather, but their breathability and wear resistance are not as good as genuine leather

Test Item:

Reference Standard Item Note Test Item 1GB  21550 free formaldehyde is a colorless gas with a pungent odor. Textiles containing formaldehyde will gradually release free formaldehyde during people's wearing process, causing respiratory and skin inflammation through contact with the human respiratory tract and skin, and also causing eye irritation. Free formaldehyde 2GB; 21550 Decomposable Harmful 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. Decomposable harmful aromatic amine dyes 3QB/T  2002.1 &Nbsp; QB/T 2002.2 Metal fittings Metal fittings are firm and comply with relevant regulations. 4. The appearance quality is free of obvious defects, the spacing between the teeth is uniform, the metal parts are free of burrs, the bonding is firm, and the stitching is even. Appearance quality 5. Stitching and bonding requirements: The needle spacing and edge spacing meet the requirements. Sewing and bonding requirements 6QB/T; 2537 &Nbsp; QB/T 2790&Nbsp; QB/T 3920&Nbsp; GB/T 22889 Friction Color Fastness (Staining) The degree of staining of various textiles dyed or printed under external friction during use or processing. Belt surface rubbing color fastness textile/leather&Nbsp; Color fastness to rubbing of dyed fur&Nbsp; Inside the belt - Color fastness to friction - Textile/leather 7 buckle and belt body binding force The buckle and belt body are clamped up and down until the belt body slips or breaks from the buckle. Read the highest value as the buckle and belt body binding force. The binding force between the buckle and the belt body is 8. The fracture force of the belt body is determined by taking a sample from the area without teeth or holes, and fixing it on the two clamps of the tension machine; Mm, start the tensile machine until the sample breaks, and read the maximum force value during the stretching process as the belt breaking force. The fracture force of the belt body is 9, and the tear force of the hole is 9. Cut the sample with the hole and fix it on the tensile machine. Hook the metal hook into the hole and start the tensile machine until the hole is completely torn. Read the maximum tear force of the hole. The belt buckle and the belt teeth are firmly engaged with a tearing force of 10 and a biting force of 10. They are respectively fixed on the two grippers of the tension machine, and the machine is started until the belt buckle slides from the belt teeth. The highest value is read as the biting force of the belt teeth Toothed bite force 11QB/T; 5246 belt body's resistance to rubbing is tested by reciprocating and folding movements at a certain frequency to verify the product quality of the belt. 12QB/T; The 4117 belt buckle is securely assembled, with uniform coating and materials that comply with relevant standards. 13 Identification signs
