Twin-Drum Washing Fastness Tester

The Twin-Drum Washing Fastness Tester is designed to evaluate the colorfastness of textiles under water washing, dry cleaning, bleaching, and detergent treatments. With dual independent drums, it can simultaneously conduct two tests at different temperatures, providing accurate and reliable results. The device supports testing for fabric durability, dye performance, and resistance to washing and dry cleaning at temperatures up to 95°C.

Application

This tester is suitable for:

(1) Water washing fastness testing of textiles;

(2) Dry cleaning fastness evaluation;

(3) Bleaching and rinse fastness testing;

(4) Assessment of detergent performance;

(5) Rapid colorfastness tests under ISO, AATCC, JIS, and GB/T methods;

(6) Laboratory quality control, textile research, and R&D applications.
