Durawash

[Instrument Name]: Durawash Print Color Fastness Tester

[Scope of Application]:

This machine incorporates the best features of similar domestic and international products. Key features include: 1. A large LCD touchscreen display for intuitive and convenient operation. 2. An inner drum made of high-quality, acid-resistant stainless steel, offering an attractive appearance and exceptional durability. 3. A safety switch on the chamber door; opening the door temporarily halts the machine’s moving parts (note: to prevent water splashing, the agitator rotation must stop before the door is opened).

This instrument is designed for specialized washing tests according to M&S standards to evaluate the effect of washing on the colorfastness of prints, as well as the stability of garments and accessories. It complies with M&S standards C15 and P5 for fabric and print stability, and meets the stability testing requirements for garments and fabrics set by international retail chains.

[Relevant Standards]: Marks & Spencer P5, C15, 8A, 8B, 8C; BS 7907.

[Test Mode]:

A solution is prepared by adding a specific amount of water and detergent to the washing drum. After heating the solution to the required temperature, the specimen is inserted. The instrument runs for a set duration, after which the specimen is removed for evaluation.

[Instrument Features]:

1. Heating elements are controlled by solid-state relays; this eliminates mechanical contacts, ensuring stable temperature, silent operation, and a long service life.

2. Features automatic water level control, automatic water intake and drainage, and dry-boil protection.

3. Touchscreen display with Chinese interface for user-friendly operation.

4. Equipped with a safety interlock switch on the door to effectively prevent burns and crushing injuries.

5. Test water temperature, duration, and water level are all automatically controlled by a microcontroller program.
