Application
- Polyester and polyester-rich blended fabric
- Outdoor, sportswear and shell fabric
- Fabric finished after high-temperature dyeing
- Continuous finishing ranges and stenters
- Automotive and technical textile fabric
- White and light shade programs where yellowing is a concern
- Mills that combine high-temperature dyeing and finishing
- Long-term supply programs that need consistent finishing results
It is suitable for mills that combine high-temperature dyeing and finishing, and for buyers who need stable performance across both steps. For polyester programs, it helps reduce the risk of performance loss and shade problems, and keeps the finishing result consistent across large production runs.
It can also be used in programs where the fabric is dyed at high temperature and then finished on a continuous line, which is common in outdoor and technical textile production.
Advantage
- Stable water repellency after high-temperature processing
- No yellowing on white and light polyester fabric
- Good compatibility with dyeing and finishing baths
