Leveling Agent Sylic D2121

It is suitable for acid and neutral dyeing of nylon, wool and its blended fabrics and yarns.

  • D2121

  • Sylic

  • 1202121

Product Description

Technical Indicators

Main ingredient

Specialty Surfactant Complex


Brownish yellow paste

pH value (1% aqueous solution)




Performance and Characteristics

1. It has a high affinity for nylon fibers, and in the early stage of dyeing, it competes with dye anions on the fibers to achieve the purpose of slow dyeing and level dyeing.

2. It has strong migration power, strengthens the migration of dyes in high temperature stage, and can effectively improve the defects such as rungs and stripes.

3. It can improve the penetration ability of dyestuff and obtain good levelness.

4. Low foam.




It is suitable for acid and neutral dyeing of nylon, wool and its blended fabrics and yarns.


Recommended Process

1. The general dosage is as follows:

Sylic D2121: 0.15-0.5% (o.w.f), the lighter the color, the greater the dosage.

Temperature and time: 95-120℃, 30-60min.

2. Rework amount: 0.5-1% (o.w.f)

Mixing method: It is recommended to bake first, then at 70-80 ℃, mix the material with a ratio of 1 to 4, stir evenly, and the product after mixing is a brown-yellow transparent liquid.

The specific process should be adjusted by the user through the sample as appropriate.

Packaging and Storage

Packaging & Storage


120kg plastic drum, sealed and stored in the dark, with a shelf life of 6 months at room temperature.

  • How to achieve level dyeing ?

    Level dyeing is achieved by i) controlled exhaustion of the dye so that it is taken up evenly and ii) migration of dye after initially unlevel sorption on the fiber. In some cases level dyeing can be influenced by dye-bath pH and/or presence of electrolytes.

  • What is leveling agent in paint?

    Leveling agents/flow modifiers are added to coating formulations to reduce the surface tension of the coating and interfacial tension between coating and substrate thus delivering superior surface qualities and optimal coating finish. They also help to optimize the viscosity during film formation process.

  • What is levelness in dyeing?

    The process of dyeing evenly where, from the great affinity between the goods and the dye, the portion first dyed would absorb too much coloring matter.

  • Which chemical is used as a Levelling agent for acid dyes?

    Fatty alcohol Sulphates :

    The product is chemically identical to commercial product (Gardinal WA). It can be used as leveling agent for dyeing nylon with acid dyes.
