PES is often blended with elastane. Even after conventional afterclearing such articles still exhibit unsatisfactory fastness properties in medium and deep shades.
Field of application
For afterclearing disperse dyeings and prints with acidic pH in a cooling dye bath or in a fresh bath, also applicable in the alkaline pH range. Suitable for dark PES/WO-dyeings
Properties
Low-foaming
Resistant to hard water
Optimum effect above 80 °C
Application
Discontinuous and continuous processes
Chemical basis
Aqueous solution of a sulphinic acid compound
Ionic character
Uncharged
