HT Fine Textile Chemical Auxiliary Agent

  Cationic fixing agent mainly through the cation and dye molecules in the anion group formation of ionic bonding, thereby sealing the water-soluble groups, to improve the wet treatment fastness. This kind of fixing agent can be divided into surfactant fixing agent and non-surface active fixing agent according to its surface activity.   [Brief information of Cationic Fixing Agent] -- Non formaldehyde cationic dye fixing agent   for reactive, direct and sulfur dyes that obviously improves various fabric fastness.   [Main composition] -- Polycationic compound.   [General properties and fields of application] -- Appearance: Light yellow to deep yellow viscous liquid -- Ionicity: cationic -- pH: 3-5 -- Solubility: easily soluble in water -- Stability: stable to acid, alkali, electrolytes and hard water -- Negligible shade fades to efficiently prevent low stripping and shade change. -- Slight shade change and does not affect original shades. -- Obviously improves rub...

For example, the reactive dye lacks of deeper color types, and it is easy to hydrolyze. Which will cause shallow color dyeing and no resistance to chlorine bleaching. After dyeing process, it will be faded when washing. It has bad wet fastness, so we need to do dye-fixing.   The types of dye-fixing agent is varied. Dye fixing agent Y is brief structural but practical. The dye-fixing agent mainly applied in the acid dye printing or dyeing as fastness agent. When it is used to deal with cotton, silk, human-made cottons, it will enhance the water washing and soap washing fastness. In the process of yarn-dyed fabric warp sizing, using this product will prevent from penetrating and stick colors. Fastness agent Y also used in color...
