[Patent number]：China Patent No. 23342211
[Calibration Certificate]：Shanghai Branch of the National Textile Metrology Station / Shanghai Textile Group Testing Standards Co., Ltd. Certificate No.ZZ-202603133
[Drafting standard]：Enterprise Standard Q/WZC012-2026SW-12D
[Scope of Application]:
It is used for testing the color fastness of various textiles to washing, dry cleaning, and milling; also used to evaluate the wash-fastness performance of dyes.
[Relevant Standards]：
GB/T 3921-2008 “Textiles — Tests for colour fastness — Colour fastness to washing with soap or soap and soda”;
GB/T 5711-2015 “Textiles — Tests for colour fastness — Colour fastness to dry cleaning using perchloroethylene solvent”;
GB/T 12490-2014 “Textiles — Tests for colour fastness — Colour fastness to domestic and commercial laundering”;
AATCC 61/1A/2A/3A/4A/5A, JIS L0860/0844, BS 1006, ISO 105 C01/02/03/04/05/06/08, DIN, NF, CAN/CGSB, AS, etc.
[Instrument Features]:
1. Features a 10-inch multifunctional color touchscreen for convenient operation.
2. Includes automatic water level control with automatic water intake and drainage functions, as well as boil-dry protection.
3. Constructed with high-grade brushed stainless steel for an aesthetically pleasing and durable finish.
4. Equipped with a safety interlock switch on the door to effectively prevent burns and crushing injuries.
5. Utilizes an imported industrial microcontroller for temperature and time programming; incorporates PID (Proportional-Integral-Derivative) control to effectively prevent temperature overshoot and ensure timing accuracy within ±1 second.
6. Employs solid-state relays to control heating elements; this eliminates mechanical contacts, resulting in stable temperatures, silent operation, and an extended service life.
7. Features multiple built-in standard programs for automatic operation via direct selection; supports program editing and storage, as well as individual manual operations, to accommodate various methodological standards.
8. Test cup manufacturing quality far surpasses that of domestic competitors:
8.1 Molding process: Our company uses a die-casting process, whereas similar products use split-welded construction; the integral die-casting process results in a smoother, flatter, and more aesthetically pleasing finish, while welding results in a rough appearance.
8.2 Internal cup treatment: Our company employs a shot-blasting process, while similar products use standard casting/forging; the additional shot-blasting step densifies the steel structure for greater durability and creates an attractive matte-like surface finish.
8.3 Cup material: Our company uses 316 stainless steel, whereas similar products use 201, 202, or 304 grades; 316 stainless steel contains molybdenum, offering superior corrosion resistance—particularly in environments involving seawater, acids, and alkalis.
8.4 Gasket material: Our company uses imported food-grade silicone, while similar products use black rubber or standard domestic silicone; imported silicone offers better corrosion resistance, making it ideal for tests involving perchloroethylene, seawater, and chlorine bleaching agents.
8.5 Cup weight: Our company’s ASTM-standard cup weighs 630g (vs. 538g for competitors), and its GB-standard cup weighs 394g (vs. 342g for competitors); the heavier, thicker construction demonstrates the use of premium materials, ensuring greater durability.
8.6 Compression spring material: Our company uses high-quality spring steel, whereas similar products use standard hard steel; spring steel provides a superior tactile feel—offering a balance of flexibility and firmness—whereas standard hard steel feels stiff and jarring to operate.
