Product Description

Overview
Direct dyes are a type of water-soluble dye primarily used for coloring cellulose fibers such as cotton and linen. They are characterized by their simple dyeing process and low cost, but relatively lower color fastness.

Key Characteristics
Water Solubility: The dye itself is soluble in water.

Directness: The dye molecules can directly adsorb onto cellulose fibers.

Applicability: Mainly used for cellulose fibers.

Application Areas
Cellulose Fibers: Primarily used for fibers like cotton and linen.

Paper: Used for coloring paper and paperboard.

Leather: Used for coloring leather.

Dyeing Process
Dyeing Process: The dye is applied to the fibers under near-neutral conditions.

Fixing Process: The dye is bonded to the fibers through heating or the use of salt agents (such as table salt or Glauber's salt).

Soaping Process: Removes unfixed dye to improve color fastness.

Advantages
Simple Dyeing Process: The process is relatively simple and easy to operate.

Low Cost: The cost of dyes and auxiliaries is low.

Wide Applicability: Suitable for various cellulose fibers.
