Moisture Friction Adhesion Improver 826Y

Product Introduction

Moisture Friction Adhesion Improver 826Y is a wet friction product with a wide range of fabric options. It is suitable for cotton fabrics, printed fabrics, blended fabrics, denim, etc. The wet friction fastness of the fabric can be improved by 1-2 levels after using this product.

Basic Specifications

• Main ingredients: Water-soluble polyurethane

• Appearance:Yellow transparent viscous liquid (dark color after prolonged storage)

• Ionicity: Weak cation

• pH value(30g/L water solution): 4.2±0.5

Mechanism of Action

• -NCO groups combine with ions on the fabric through covalent bonds to improve dye fixing rate.

• A three-dimensional network structure forms a continuous and smooth film on the fabric surface, preventing dye loss.

• Cationic and dyes form insoluble color precipitates attached to the fabric.

Immersion and Padding Process

Moisture Friction Adhesion Improver 826Y usage: Padding process

According to the type and concentration of the dye used, and the type and form of the processed fabric, the following methods are used:

Padding process

• Dosage: 20~50g/L (adjust according to color depth)

• Process: Dyed fabric (PH≤7) → one padding and one rolling (rolling residual rate: 80~85%) → drying

Impregnation Process

Moisture Friction Adhesion Improver 826Y usage: Impregnation process (limited to washing factories)

According to the type and concentration of the dye used, and the type and form of the processed fabric, the following methods are used:

Impregnation process (limited to washing factories)

• Dosage: Moisture Friction Adhesion Improver 826Y: 3~5% (o.w.f.) (adjust according to color depth), bath ratio: 1:10~20

• Process: Dyed fabric (pH<7) → impregnation (room temperature, time: 15~20 min) → drying (60~70℃)
