Applications:

1. Textile and Garment Industry

This is the core application field of the equipment. It is used to test the dry rubbing and wet rubbing color fastness of various yarns, woven fabrics, knitted fabrics, and printed textiles. By simulating friction during daily wear, the equipment detects whether there is any “loose color” or dye transfer on the fabric surface, ensuring that garments will not fade or stain other fabrics during wearing or washing.

2. Leather and Footwear Manufacturing

The equipment is used to evaluate the rubbing resistance of surface coatings on natural leather and synthetic leather materials such as PU and PVC artificial leather. This is essential for assessing the resistance to fading and color transfer of shoe uppers, luggage, automotive interior leather, and sofa leather during use.

3. Plastic and Rubber Products

It is used to test the rubbing color fastness of coated or dyed surfaces on plastic products, rubber components, toys, mobile phone casings, and similar products. This ensures that surface colors or printed patterns will not easily wear off or peel away during long-term use, handling, or cleaning.

4. Packaging and Printing Industry

The equipment is used to evaluate the rubbing resistance of printed layers on paper, paperboard, labels, films, and related materials. This test ensures that printed text and graphics remain clear and will not become blurred or contaminate adjacent surfaces during transportation, handling, and daily use.

5. Automotive and Furniture Interiors

It is used to test the rubbing resistance of textile and leather surfaces used in automotive seats, steering wheel covers, door interior panels, furniture sofas, and related interior materials. The test helps ensure that interior materials maintain their appearance and color stability after long-term seating and friction.

Product Information:

This machine uses dry or wet white cotton cloth attached to the surface of the rubbing hammer. With a specified load and number of cycles, the machine rubs colored test specimens. The color fastness of the specimen is then evaluated by comparison with a gray scale. It can also be used for rubbing tests of organic solvents.

FAQ

1. What is an Electric Crockmeter for Color Fastness Testing used for?

The Electric Crockmeter is used to evaluate the color fastness of textiles, leather, fabrics, printing materials, and coated surfaces against dry or wet rubbing. It helps determine how easily color transfers from one material to another during friction.

2. What materials can be tested with an Electric Crockmeter?

This instrument is suitable for testing textiles, leather, shoes, garments, upholstery fabrics, synthetic materials, printing inks, and coated products. It is widely used in textile, footwear, and quality control laboratories.

3. What is the difference between dry rubbing and wet rubbing tests?

In a dry rubbing test, a dry white test cloth is used to rub the specimen surface. In a wet rubbing test, the rubbing cloth is moistened before testing. Wet rubbing tests usually provide a stricter evaluation of color transfer performance.

4. Which testing standards does the Electric Crockmeter comply with?

Most Electric Crockmeters are designed to comply with international standards such as ISO 105-X12. AATCC 8. AATCC 165. GB/T 3920. and other related textile color fastness testing standards.

5. Why is an Electric Crockmeter important in quality control?

The Electric Crockmeter helps manufacturers ensure product color durability and reduce customer complaints caused by color fading or staining. It is an essential instrument for maintaining product quality and meeting international testing requirements.
