Short Description:

Key indicators
1. Tear force. Tear force is a key indicator of leather for clothing, which basically reflects the durability of leather
2. Elongation under load. Elongation under load reflects the tensile properties of leather, usually the elongation under a specified load of 5N/mm2. For all leathers used for clothing, the elongation under load should be between 25% and 60%.
3. Color fastness to rubbing. Color fastness to rubbing reflects the binding fastness of dyes in leather, and is usually tested by 50 dry rubbings and 10 wet rubbings under a specified load. For all leathers used for clothing, the dry rubbing fastness should be greater than or equal to level 3/4, and the wet rubbing fastness should be greater than or equal to level 3.
4. Safety performance. The safety performance of leather mainly involves environmental safety indicators such as heavy metals, hexavalent chromium, formaldehyde, and banned aromatic amine dyes.
Purchase tips
1. Manually check the quality of leather. Poor quality leather may have defects such as cracking, discoloration, and cracked surface. The following methods can be used to identify it when purchasing:
Cracking: Press the leather surface with one hand, stretch the leather surface with the other hand, and use the index finger to push upward from the inside of the leather. If the coating cracks, it is cracking.
Discoloration: Use a slightly damp white soft cloth to wipe the leather surface repeatedly for 5 to 10 times. If the white soft cloth is stained, it can be considered that the leather is discolored.
Cracked surface: Fold the smooth surface into four corners and press it hard with your hands. If cracks appear on the smooth surface, it can be considered as cracked surface.
2. Smell the odor. Genuine leather usually contains an easily detectable grease smell, but it should not have an irritating or rancid odor. If you personally think that the smell of the clothing is unacceptable, it is not suitable to buy it.
3. Choose well-known merchants and brands. Give priority to purchasing leather clothing in regular large shopping malls. Good merchants have strict control over the quality of goods purchased, and the quality of the clothing they sell is better guaranteed.
Give priority to buying products from well-known brands. Most brand companies have rich experience in clothing processing and standardized management, good production conditions and equipment, strict selection and quality control of raw materials, and especially no “fake” products.
4. Check the label. Carefully check the factory name, address, trademark, specifications, material type, textile composition and content, implementation standards, and certificate of conformity on the label.
