Theproduct is used to improve the color fastness to wet treatment of the dyedfabric. It can improve the color fastness to washing and perspiration throughforming non-soluble colored matters with the dyes on the fabric, and sometimesit can also improve the color fastness to sunlight. The product is also usedfor color fixing after dyeing of the cotton by active, direct and sulfur dyes.It can “bridge” between the dyes and the fibers to form compound, namely toreact with the dye molecules while cross-linking with the cellulosic fibers, toform highly diversified cross-linking system, thus to firmly combine togetherthe dyes and fibers, prevent the dyes from falling out of the fibers, andimprove the dye fastness. The active matters in the coloring fixing agent cancondensate with each other and form a three-dimensional film with reticulatestructure on the fiber surface to seal the dyes, thus improve the smoothness ofthe fabric, reduce friction coefficient，preventwear and tear, and further avoid swelling, dissolution and falling of the dyesin the process of wet friction, and finally improve fastness to wet friction.

According to specific fabric and dye, the dosage may vary. The value above isfor reference only.
Treatment temperature: 70 – 80℃
Time: 20 – 30min
Bath ratio: 1:15 to 20 treatment →rinse bywater
After dyeing, decrease the temperature to 70 - 80℃, and addquantitative acid color fixing agent for color fixing→rinsing→drying
