Veslic Leather Crocking (Friction Colorfastness) Tester
Category：Interior Material Tester
Introduction
The Veslic Leather Crocking Tester is designed to evaluate the colorfastness of leather, textiles, vinyl, stitched seams, plastics, and other materials under friction conditions. It simulates wear-related color changes, including dry and wet testing. The instrument features three independent test stations, each capable of applying loads of 500 g or 1000 g. Samples are clamped and secured on a vibration test bed, with up to 25% tension applied during testing.
Application
The Veslic Leather Crocking Tester is suitable for:
Evaluation of leather and textile friction colorfastness
Assessment of stitched seams and vinyl material durability
Simulating real-life friction scenarios, such as shoe-to-shoe contact or crossed-leg wear
Dry and wet testing using deionized water or synthetic sweat
Testing with alternate friction materials such as rubber pads, sandpaper, or cotton fabrics
Typical Test Products Include:
Automotive leather seats and upholstery
Footwear leather and synthetic leather
Garments, gloves, and fashion accessories
Plastic and coated materials
