Washing fastness tester is an instrument for measuring the color fastness of materials such as dyes, printed fabrics, dyed fabrics, and prints. It evaluates the color fastness and durability of samples by repeatedly washing them at different temperatures.
The Washing fastness tester works based on the operating principle of a household washing machine. It consists of a large capacity circular stainless steel drum with samples and some detergent. The drum is rotated by a motor and drive belt to move the sample horizontally and vertically through the water and detergent to simulate a real-world home washing machine.
