The quality judgment criteria of microfiber leather mainly include the following aspects:

Texture and luster: High-quality microfiber leather has a natural, clear texture and soft luster, while inferior products have blurred lines and a too bright or dull luster. In addition, the texture of high-quality microfiber skin is clearer, and the surface layer has a strong sense of dermis.

Feel and elasticity: good microfiber leather has a delicate feel, moderate elasticity and rapid rebound, while inferior products have a rough feel and lack elasticity.

Hydrolysis resistance: The hydrolysis resistance of microfiber leather is one of the important indicators of its durability.

pH test: By measuring the pH of a leather sample in contact with a solution, the pH of the leather can be judged and its quality can be evaluated accordingly. Qualified leather should be in the pH range of 3.5 to 5.5 to ensure its durability and comfort.

Physical properties: including velvet, volatile organic compounds, mechanical properties, color fastness, etc. These performance indicators have a direct impact on the quality and longevity of leather products.

Sensory performance: including quantitative evaluation methods for sensory properties such as softness, thickness, fullness, elasticity, and softness.

Other characteristics: such as scratch resistance, whether each piece has the same texture, whether there is a chemical fiber fabric or texture on the reverse side, etc.

The quality of microfiber leather is judged by a variety of criteria, including texture and luster, feel and elasticity, hydrolysis resistance, pH test, physical properties, sensory properties and other characteristics. Together, these criteria form a comprehensive evaluation system for the quality of microfiber leather.
