Perspiration fastness improver HZ
【Introduction】 

Perspiration fastness improver is mainly applied to all kinds of natural fiber by reactive dyes, increase perspiration color fastness can be processed light fabric perspiration light prison complex upgrade 0.5-1 degree level. After the impact of textile processing and dyeing looking light feel small. 

 reactive dyes are the most commonly used dyes, with wet fastness and excellent levelness, but reactive dyes commonly mixed colors such as turquoise, pink, purple and gray dyed fabrics such as light perspiration fastness is generally poor. But mostly reactive dyeing cotton clothing after contact with human sweat, the sunlight becomes particularly prone to fade (light composite color fastness to perspiration: due to the role of amino acids in human sweat, will cause oxidation and decomposition reactions of light discoloration or fading) particularly domestic single Japan and export orders are perspiration light fastness has become an important indicator of the quality assessment of textiles. 

The product is used for the active, direct, sulfur dyed product after treatment, can significantly improve the fastness of the fabric.
