As a leading belt factory specializing in OEM/ODM services, we pride ourselves on adhering to the ISO 11640:2018 standards, ensuring that each of our belts meets the highest quality expectations.

**1. Testing Requirements and Significance**

In accordance with the ISO 11640:2018 standard, we have conducted a rigorous colorfastness test on our leather belts. This test is essential to determine the resistance of the belt's color to rubbing, a common cause of color fading in everyday use. Our belts have undergone a specific test requirement of rubbing dry at 50 cycles, with the results demonstrating a colorfastness rating of 4 or higher, fully compliant with the standard.

**2. Test Methodology and Standards**

Our belts are tested using the ISO 11640:2018 protocol, which involves subjecting the leather to a controlled rubbing action with a dry cloth. This simulates the friction the belt may experience during normal wear. The test is conducted with a precision instrument that ensures consistent pressure and motion, providing reliable and repeatable results.

**3. Test Results and Analysis**

Our belts have successfully passed the colorfastness test with flying colors. After 50 cycles of dry rubbing, the belts showed no significant color transfer or fading, achieving a minimum rating of 4 on the colorfastness scale. This indicates that our belts are highly resistant to color loss due to friction, ensuring their vibrant appearance remains intact over time.

**4. Product Features and Benefits**

Our eco-friendly belts are crafted from premium cowhide, ensuring not only durability but also a reduced environmental impact. The combination of high-quality materials and meticulous craftsmanship results in belts that are both stylish and long-lasting. With our OEM/ODM services, we cater to the unique needs of our clients, offering personalized belts that reflect their brand's identity.

**5. Conclusion**

Our commitment to the ISO 11640:2018 standard is a testament to our dedication to quality. By achieving a colorfastness rating of 4 or higher after 50 cycles of dry rubbing, our belts stand out in the market for their exceptional performance and longevity.
