Zydex生产低和高分子量polymeric surfactant based wetting agents that provide excellent cleaning action for waxes and oils from cotton as well polyester surface. The wetting agents make the fiber surface clean and help improve the solidity of reactive and disperse dyeing. The post finish feel is improved helping to reduce the cost of finishing. The instant wetting which low molecular weight surfactants when used alone give on the surface is artificial which does not necessarily lead to good quality dyeing. High molecular weight surfactants such as Zycowet Series, although slow in wetting, gives far superior leveling and dyeing depth compared to conventional emulsifiers.
