Color Fastness to Washing Tester

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.

Test Procedures

(1) Fill the test cups with the specified washing solution according to the selected standard.

(2) Place textile specimens and adjacent fabrics into the test cups.

(3) Secure the cups onto the rotating rack and close the chamber lid.

(4) Set the test temperature, time, and rotation parameters via the touchscreen.

(5) Start the test and monitor temperature and time curves if required.

(6) After completion, the instrument alarms automatically and stops operation.

(7) Remove specimens for evaluation of color change and staining.

Maintenance Information

You should regularly clean the test cups and chamber to prevent residue buildup. Ensure sufficient water is present before heating to avoid dry operation. Periodically inspect the bearings, transmission components, and electrical connections. When not in use for extended periods, disconnect the power supply and keep the instrument in a dry environment.
