Overview

Irect Red 4b is a water-soluble direct dye with the characteristics of uniform dyeing, strong adhesion and good light resistance. It is widely used in dyeing processes in textile, papermaking and leather industries.

irect Red 4b Features

Strong Adhesion

irect Red 4b forms stable hydrogen bonds with cellulose molecules through the sulfonic acid group in the molecule, and the dye penetrates deeply, colors quickly, and is not easy to fade. Its color fastness on the fiber can reach above level 4, which effectively reduces the fading after washing and friction.

Uniform Coloring

irect Red 4b is made by a process with good dispersion and particle fineness of less than 10 microns, ensuring that the dye is evenly distributed during the dyeing process to avoid color spots or color differences.

High Temperature Resistance Does Not Change Color

It has excellent thermal stability, and there is no obvious change in color after continuous heating at 130°C for 1 hour. It is suitable for production lines that require heat setting or high temperature drying processes.

irect Red 4b Application

Textile Dyeing

irect Red 4b is widely used in the direct dyeing process of cotton and viscose fibers, and is suitable for home textiles, clothing and other industries.
