FAQ
1. How do I select between 550 ml and 1200 ml test cups?
The selection depends on the testing standard being followed. Some standards specify liquor ratio and specimen size, which determine the required cup capacity.
2. What factors influence the repeatability of washing fastness tests?
Key factors include temperature stability, rotation speed consistency, detergent concentration, and correct specimen preparation. Maintaining standard conditions is critical for reproducible results.
3. Can this machine perform both washing and dry-cleaning tests?
Yes. With appropriate solvents, seals, and accessories, the machine can simulate both washing and dry-cleaning conditions.
4. Why is temperature control important in fastness testing?
Color fastness is highly sensitive to temperature. Even small deviations can affect dye behavior, so precise control ensures compliance with testing standards.
5. Is the machine suitable for different fabric types?
Yes. It can test a wide range of textiles, including cotton, polyester, blends, and technical fabrics, as long as the appropriate standard method is selected.
