The main differences between water-based PU leather and ordinary PU leather are environmental protection, physical properties, production process and scope of application
Environmental protection: Water-based PU leather uses water as a dispersion medium in the production process, so it is non-toxic, non-flammable, and does not pollute the environment. It has the characteristics of energy saving, safety and environmental protection. In contrast, ordinary PU leather may produce toxic and harmful waste gas and wastewater during production and use, which has a certain impact on the environment and human health.
Physical properties: Water-based PU leather has excellent physical properties, including high peel strength, high folding resistance, high wear resistance, etc. These properties make water-based PU leather a better alternative to genuine leather and traditional solvent-based synthetic leather. Although ordinary PU leather also has certain physical properties, it may not be as good as water-based PU leather in terms of environmental protection and durability.
Production process: Water-based PU leather is made of special water-based process formula and environmentally friendly equipment, and has the advantages of good wear resistance and scratch resistance, and ultra-long hydrolysis resistance. These advantages are derived from the water-based surface layer and auxiliary agents, which double its wear resistance and scratch resistance, which is more than 10 times higher than that of ordinary wet synthetic leather products. The production process of ordinary PU leather may not involve these environmental protection and performance improvement technologies.
Scope of application: Water-based PU leather is widely used in many fields such as shoes, clothing, sofas, sports goods, etc. due to its environmental protection and excellent physical properties, and meets various requirements for synthetic leather environmental protection at home and abroad. Although ordinary PU leather is also widely used in the decoration of bags, clothing, shoes, vehicles and furniture, its scope of use may be subject to certain restrictions in the context of increasingly stringent environmental protection requirements.
In summary, water-based PU leather has obvious advantages over ordinary PU leather in terms of environmental protection, physical properties, production process and scope of application, and is a material that better meets modern environmental protection requirements and high performance requirements. -

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. -
