Formaldehyde fixing agent belong to polyamine cationic compound, can structured water-insoluble macromolecular compounds, so that can improve washable color fastness and rubbing fastness of dyeing fabrics. Suitable for cotton, hemp, viscose and other reactive, direct dyes dyeing or printing fixing process. Property and Characteristics
Good fixing property, which can improve soaping, washing fastness significantly.
No discoloration, no influence of dyeing fabrics vividness.
No influence on dyeing fabrics primary hand feeling.
Wide suitability on dyeing bath PH value, resistance to hard water, acid, high alkali, high temperature, which can be used as latter mercerized fixing agent.
Excellent hydrophilic on processed fabrics.
