Color Fastness to Washing Tester
Category：Color Fastness Tester
Introduction
The Color Fastness to Washing Tester is a laboratory testing instrument used to evaluate the resistance of dyed and printed textiles to color change and staining during washing. You use this tester to simulate domestic or commercial washing conditions under controlled temperature, time, and mechanical action, ensuring reliable and repeatable assessment of wash fastness performance in accordance with international standards.
Application
You use this instrument for wash fastness testing of a wide range of textile materials, including:
Cotton, wool, silk, and linen fabrics
Chemical fibers and blended textiles
Dyed and printed fabrics
Garments and textile components
It is also suitable for evaluating the washing fastness performance of dyes. The tester is widely used in textile dyeing and finishing plants, dye manufacturers, quality inspection laboratories, and research institutions.
