Zydex manufactures low and high molecular weight polymeric surfactant-based wetting agents that provide excellent cleaning action for waxes and oils from cotton as well polyester surfaces. The wetting agents make the fibre surface clean and help improve the solidity of reactive and dispersed dyeing. The post-finish feel is improved helping to reduce the cost of finishing. Low molecular weight surfactants achieve instant artificial wetting due to the surfactant layer and do not indicate real clean-up of the fibre. This leads to inconsistent levelling, lower colour value and poor feel.
High molecular weight surfactants such as Zycowet Series, although slow in wetting, gives far superior levelling and dyeing depth compared to conventional emulsifiers.
Zycodesize is a new generation very effective additive for grey fabric to achieve higher TEGEWA value and a softer feel.
