TY-8807A2 Cationic modifier

TY-8807A2 is a special cationic modifier, formulated as a high-performance cationic polymer. When it reacts with cellulosic fibers like cotton, it transforms the fibers' surface charge to cationic. This modification significantly improves the dye uptake of anionic dyes, such as reactive and direct dyes.

It is primarily used as a dyeing intensifier and fixing agent for cotton fabrics, and is also highly effective for improving the leveling of R/C (rayon/cotton) fabrics. Furthermore, it is a key auxiliary for garment pigment dyeing and pigment overdyeing in denim processing.

Key Features & Performance Advantages

1. High Dye Uptake: The primary benefit is a high dye uptake rate, leading to deeper shades with less dye consumption. It's an easy-to-use solution for intensifying colors.

2. Improves Levelness: It significantly improves uneven dyeing issues, particularly in difficult-to-dye R/C fabrics, resulting in a more uniform and consistent color.

3. Enhances Pigment Performance: In pigment dyeing applications, it enhances pigment uptake and improves the final soaping fastness, leading to a more durable and wash-resistant finish.

4. Eco-Friendly Formula: This product is free from free formaldehyde and is an environmentally friendly choice for modern textile pretreatment.

Recommended Application Process

The following process for R/C knit fabric dyeing is provided as an example. The pretreatment step is also applicable for deepening the color of cotton with anionic dyes.

Process Flow: Pretreatment → Rinsing → Dyeing → Post-treatment → Drying

1. Pretreatment (Modification)

• Modifier Dosage: 3–5% (o.w.f) - (Add 3–5 KG of product per 100 KG of fabric)

• Temperature & Time: 40–60°C for 20–40 minutes

2. Rinsing

• Method: Cold water treatment. Adequate rinsing is crucial to prevent dyeing defects. Rinsing twice is recommended.

3. Dyeing

• Note: This auxiliary is not suitable for use in pre-alkaline dyeing processes. For the most even dyeing results, a stepwise addition of salt and alkali is recommended.

4. Post-treatment

• Method: Follow the same procedure as your conventional dyeing process.

Scope of Application

TY-8807A2 is mainly used for:

• Fabric modification before pigment dyeing of cotton fabrics.

• Modification in reactive dyeing to improve dye uptake and levelness.

• Leveling dyeing of R/C fabrics.

• Pigment overdyeing in denim processing.

Storage and Packaging
