The Automated Color Rubbing Tester is designed to evaluate the color fastness of textiles when subjected to dry or wet rubbing. Its acrylic sample holder with a secure pin system ensures quick sample setup and consistent, repeatable test results. This tester is equipped with a pre-set electronic counter capable of tracking up to 999,999 strokes.
The Color Proof Station is vital for maintaining consistency in color reproduction across printing processes. Color and density measurement ensure high-quality output, but stable observation conditions are essential to avoid discrepancies in the final product’s appearance. Since observation environments often vary, using standardized lighting like the CIE D50 light source recommended by ISO 3664 mitigates misunderstandings in color matching.
Principle of Color Fastness to Rubbing The color rubbing test involves securing a dry or wet cotton cloth to the friction head of the machine using a metal clamp. The sample is then rubbed against the white test cloth under controlled conditions. After the test, the degree of color transfer is evaluated by comparing the stained test cloth to a standardized gray scale card.
Importance of Rubbing Fastness Testing In everyday use, fabrics experience various types of friction—like the contact between a garment’s outer fabric and its lining, friction at seams, and surface contact from sitting. Poor rubbing fastness can lead to color transfer, affecting garment appearance and potentially causing safety concerns. Ensuring good rubbing fastness is crucial for maintaining product quality and durability.
Understanding the Color Rubbing Tester The color rubbing tester simulates real-world friction conditions to assess the color retention of textiles and other materials. Evolving from manual friction testers to today’s automated versions, these devices now provide more precise and consistent testing for textiles, leather, and similar products.
Comparing Different Rubbing Test Standards Different countries use varied testing standards for rubbing fastness. For instance, the AATCC 8 method specifies a 65% moisture content for wet rubbing tests, whereas other standards require 95% to 100%. The table below outlines key differences in test parameters:
| Parameter | GB/T 3920.5-1997 | AATCC 8-2004 | JIS L 0849-1996 |
| Sample Size (mm) | 200×5 | 130×50 | 140×50 |
| Friction Cloth Size (mm) | 50×50 or 25×100 | 50×50 | 50×50 |
| Friction Head Size | ∮16mm (round) | ∮16mm (round) | ∮16mm (round) |
| Friction Head Weight | 900g | 900g | 200g or 900g |
| Friction Stroke (mm) | 100 | 104±3 | 100 |
| Friction Speed | 10 strokes/10s | 10 strokes/10s | Varies by tester |
| Wet Friction Cloth Moisture (%) | 100±5 | 65±5 | 100 |
| Evaluation Method | GB Gray Scale | AATCC Gray Scale | JIS Gray Scale |
