As an important material widely used in clothing, footwear, furniture, and automotive interiors, leather's quality and performance have an important impact on the overall quality of the product and user experience. The test items include:
1. Appearance inspection
Color: Evaluate the color consistency and fading resistance of leather.
Texture: Check the surface texture and texture of leather to meet consumers' requirements for texture.
Defects and scars: Check whether there are obvious defects, scars, or cracks on the surface of the leather.
2. Physical performance test
Abrasion resistance: Evaluate the durability of leather under friction and wear conditions, which is particularly important for footwear and furniture leather.
Tensile strength: Test the ability of leather to resist breaking during stretching to ensure that leather products will not break easily during use.
Elongation: Measure the ductility of leather during stretching to evaluate its adaptability in practical applications.
Tear resistance: Detect the ability of leather to resist tearing to ensure its integrity under high-stress conditions.
Thickness and density: Measure the thickness and density of leather to ensure its uniformity and consistency.
3. Chemical performance test
Harmful substance detection: including hexavalent chromium, formaldehyde, banned azo dyes, heavy metals (such as lead, cadmium, etc.), halogenated flame retardants, volatile organic compounds (VOCs), and other harmful substances to ensure that leather products meet environmental protection and safety standards.
Free fatty acid content: measure the content of free fatty acids in leather to evaluate its chemical stability.
4. Color fastness test
Rubbing color fastness: evaluate the color fastness of leather under friction.
Water stain color fastness: test the color stability of leather under the action of water.
Perspiration color fastness: evaluate the color retention ability of leather under the action of sweat.
Light fastness: simulate sunlight exposure conditions to evaluate the light resistance of leather in long-term use.
5. Special performance test
Waterproofness: test the waterproof performance of leather to ensure that it can still maintain a certain degree of dryness in a humid environment.
Antifouling: Evaluate the leather's antifouling ability to ensure that it is not easily contaminated by stains during use.
Breathability: Test the breathability of leather to meet consumers' requirements for comfort.
6. Microbiological testing
Test whether there are microorganisms such as bacteria, fungi, and mold in leather products to ensure the hygiene and safety of the products.
