The Crockmeter is a specialized instrument used to evaluate the color fastness to rubbing or crocking of dyed, printed, and coated materials. It simulates repeated rubbing under a fixed pressure and stroke length to determine how much color transfers onto a standard test cloth.
Widely used in textile factories, garment QC departments, dyeing mills, leather processors, and print finishing lines, this tester provides repeatable, accurate, and standard-compliant rubbing performance.

❓ FAQs
1. What is the difference between dry and wet crocking?
• Dry: Rubbing with dry test cloth
• Wet: Test cloth wetted to specific moisture before rubbing
2. Does the Crockmeter require calibration?
Only the rubbing pressure and stroke length need periodic verification.
3. Can I test leather or coated fabrics?
Yes—the tester works for almost all dyed or printed surfaces.
4. How many rub cycles are usually performed?
Typically 10 or 20 cycles, depending on the standard.
