Product introduction

TY5-7B is a high-performance dye promoting agent that enables vibrant, high-quality dyeing of delicate fibers at significantly lower temperatures. It is suitable for use at 80–85°C with various acid dyes and wool reactive dyes.

This innovative agent is designed to enhance dye uptake, accelerate dyeing speed, and reduce residual dye in the bath. By doing so, it not only saves energy but also protects fiber quality and improves the spinnability of wool. It is the ideal choice for dyeing semi-worsted wool, mercerized wool, other animal hairs, wool blends, nylon, and silk.


Key Features & Performance Advantages

  1. Energy-Saving Low-Temperature Dyeing:

    • TY5-7B successfully reduces the required dyeing temperature for wool from the traditional 98°C down to 80–85°C.

    • It achieves the same color yield as conventional boiling dyeing but with brighter shades.

    • This process effectively inhibits the high-temperature yellowing of fibers and preserves the natural, soft hand feel of wool, while also improving spinning performance.

  2. Enhanced Dye Adsorption and Diffusion:

    • The agent has excellent dispersing properties that disaggregate dye molecules, promoting their adsorption and diffusion at lower temperatures.

    • It accelerates dye uptake on the fiber surface and improves diffusion within the fibers, which is the key mechanism for lowering dyeing temperatures.

  3. Eco-Friendly and User-Friendly Formula:

    • This is an APEO-free, environmentally friendly, bio-based auxiliary.

    • It is easily soluble in water and exhibits low foaming characteristics, making it easy to handle in production.

  4. No Compromise on Quality:

    • The use of TY5-7B has no negative effect on the color fastness of the final product.


Recommended Application

Dosage may be adjusted based on fiber condition, dye concentration, and specific dyeing methods. Pre-testing is always recommended.


Scope of Application

TY5-7B is mainly used for the dyeing of high-value and temperature-sensitive fibers, including:
