Denim Fabric Modifying Agent

Unichem Precat 520 – Denim Fabric Modifying Agent for Superior Dyeing Results

Unichem Precat 520 is a highly effective denim fabric modifying agent designed to optimize the paint dyeing process, especially for cellulose-based fibers like pure cotton and denim. It enhances the final fabric’s color fastness and provides an improved hand feel, making it a must-have for achieving high-quality results in textile dyeing.

This unique product eliminates or reduces the need for adhesives, alkali, and salt, simplifying the process and improving efficiency. Unichem Precat 520 works by cationizing the fibers, resulting in non-alkali, non-salt dyeing and creating a fabric that resists fading while maintaining its vibrant appearance.

Whether you are involved in paint overdyeing of denim or dyeing pure cotton, Unichem Precat 520 will enhance the fabric's finish, providing better color retention and a smoother, more vibrant hand feel.

Key Features of Unichem Precat 520

• Appearance: Colorless and transparent mucus for easy integration into your dyeing process.

• Ionic Nature: Cationic, ensuring the fibers bond well with the dyes for uniform color distribution.

• Viscosity: 90,000–130,000 cp at 30°C, providing the correct consistency for optimal application.

• pH at 1% Solution: 7±1, ideal for use without disturbing the fabric's pH balance.

• Solubility: Fully soluble in water for smooth and even application.

Benefits of Using Unichem Precat 520

1. Improved Color Fastness: Enhances the dyeing process, allowing fabrics to retain vibrant colors without fading after washing or light exposure.

2. Enhanced Fabric Feel: Fabrics treated with Unichem Precat 520 will have a softer, smoother hand feel while maintaining brightness.

3. Simplified Dyeing Process: No need to add alkali or salt, making the process easier and reducing chemical usage.

4. Non-Alkali and Non-Salt Dyeing: Achieve superior color retention and consistency without requiring additional alkali agents.

5. Versatile Application: Perfect for denim overdyeing and cotton paint dyeing, giving textile manufacturers flexibility in their operations.

How to Apply Unichem Precat 520

Unichem Precat 520 can be used in various denim and cotton fabric dyeing processes. Below are two recommended applications based on different processes:

1. Dipping Process:

• Dilution: Dilute Unichem Precat 520 at a 1:2 ratio.

• Dosage: Apply 2-5% (o.w.f).

• Temperature and Time: Process at 60°C for 10-20 minutes.

• Follow-up: Drain the excess solution and dewater (if dyeing in the same bath, you can directly add paint dyes without dewatering).

• Dyeing: Dye at 70°C for 30 minutes.

2. Set Dyeing Process:

• Dilution: Dilute Unichem Precat 520 at a 1:3 ratio.

• Dosage: Apply 1-3% (o.w.f).

• Temperature and Time: Process at room temperature for 10-20 minutes.

• Follow-up: Drain and dewater, then proceed with nano-coating at room temperature for 10-20 minutes.
