1. Application
Pre-dyeing treatment
Before dyeing, wetting agent is used to treat fabrics to make the fiber surface easier to be infiltrated by
dye solution, thereby promoting the uniform diffusion of dye in the fiber and improving the dyeing effect.
Improve dye permeability
Wetting agent can reduce the surface tension between dye solution and fiber, making it easier for dye to
penetrate into the fiber, improving the uniformity and color fastness of dyeing.
Improve dyeing effect
During the dyeing process, wetting agent can prevent dye from aggregating on the surface of fabric, reduce
color spots and color difference, and ensure the consistency of dyeing effect.
Applicable to a variety of fibers
Wetting agent is suitable for natural fibers (such as cotton and linen) and synthetic fibers (such as polyester
and nylon). The appropriate type of wetting agent can be selected according to the characteristics of the fiber.
2. Advantages
Improve dyeing efficiency
Wetting agent can reduce dyeing time, improve production efficiency and reduce energy consumption by
improving the contact between fiber and dye solution.
Enhance dyeing uniformity
Wetting agent can make the dye solution evenly distributed on the fiber surface, avoid color spots and color
difference, and improve the overall dyeing quality of fabric.
Improve color fastness
By promoting the penetration of dyes into the fiber, wetting agents help improve the color fastness of fabrics
and reduce fading caused by washing and friction.
Reduce dyeing costs
The use of wetting agents can reduce the amount of dyes and auxiliaries, reduce wastewater treatment costs,
and meet the dual needs of environmental protection and economic benefits.
Environmental protection and safety
Modern wetting agents mostly use environmentally friendly formulas, have good biodegradability, reduce
pollution to the environment, and meet textile safety standards.
Versatility
Some wetting agents have the functions of emulsification, dispersion, and antistatic, which can simplify the
dyeing process and reduce the types of auxiliaries used.
Strong adaptability
Wetting agents can be used under different temperatures, pH values and dyeing process conditions, with
strong adaptability to meet diverse production needs.
3. Selection and use recommendations
Choose according to fiber type: anionic wetting agents are suitable for natural fibers, and non-ionic wetting
agents can be used for synthetic fibers.
Control dosage: Excessive use may cause foaming of the dye solution and affect the dyeing effect. It is
recommended to add it according to the recommended concentration.
Combined with other auxiliaries: Wetting agents can be used in combination with dispersants, leveling agents,
etc. to further improve dyeing quality.
Focus on environmental protection: Low-foaming and biodegradable wetting agents are preferred to reduce
the impact on the environment.
Dyeing wetting agents significantly improve dyeing efficiency and quality by improving the interaction between
fibers and dyeing liquids. At the same time, they have environmental and economic benefits and are indispensable
auxiliaries in modern textile dyeing processes.
