Introduction：
   QY-802 wet friction fastness promoting agent is macromolecular polymer that can increase dry and wet friction fastness of fabric. It is mainly used to increase dry and wet friction fastness of reactive dye and sulfur dye. After treatment of QY-802, it can increase the dry and wet friction fastness of reactive dye and sulfur dye by 1-2 grades. It is environmentally friendly product.
Technical index：
Appearance：Colorless to canary liquid
Ionicity：Weak cation
PH value：6.5-7.5
Solubility：Dissolving in water
Features：
1, It can effectively increase dry and wet friction fastness of fabric, and promote the washing fastness.
2, It does not have any impacts on chromatic light and feeling of fabric.
3, It can be used with cation and nonionic softening agent, but can not be used with anion softening agent and fixative.
4, Little dosage with well washing fastness.
