Dual-Station Motorized Rubbing Color Fastness Tester
The Dual-Station Motorized Rubbing Color Fastness Tester is designed to evaluate the color fastness to rubbing of dyed textiles and leather materials. The test is performed by wrapping dry or wet white cotton cloth around a rubbing cone and applying reciprocating rubbing motion against the specimen fixed on the test table. The degree of color transfer from the specimen to the cotton cloth is then assessed to determine the color fastness grade.
The instrument provides stable, repeatable, and standardized testing conditions for laboratory evaluation and quality control.
Applications
(1) Color fastness to rubbing testing of woven fabrics, knitted fabrics, and nonwoven textiles.
(2) Evaluation of dye fixation performance of dyed fabrics during textile finishing processes.
(3) Dry and wet rubbing color fastness testing of leather and coated leather materials.
(4) Quality control testing for garments, upholstery fabrics, home textiles, and leather products.
(5) Comparative testing for process optimization in textile dyeing and finishing laboratories.
(6) Routine inspection testing in third-party laboratories and certification bodies.
(7) Incoming material inspection and outgoing product verification for textile manufacturers.
