Soda Substitute CY-518 Performance and Characteristics

1. It is used as a fixing base for dyeing reactive dyes. It can be used as a substitute for caustic alkali, soda ash, trisodium phosphate and mixtures thereof.

2. The amount used in fixing is small, only 1/8-1/10 of the amount of soda ash.

3. Due to the synergistic effect of a variety of basic compounds, the ability to control the pH value of the dye bath is stronger, ensuring uniform dyeing, continuous dyeing, and controlling the dyeing speed. It is especially suitable for varieties such as emerald blue, grass green, and bean paste to reduce the rate of staining.

4. The fixing bath has low viscosity and can avoid the staining problem caused by the viscosity of the fixing bath. It can be used in various types of dyeing equipment, especially for low-bath dyeing of cheese yarn.

5. The residual alkali is easy to wash off, which can save two times of washing.

Application

Soda Substitute CY-518 Application

It is mainly used in industry for pad dyeing of vat dye suspension, leuco acid dyeing, and dyeing of dispersive and soluble vat dyes. It can also be used for dyeing silk/wool interwoven fabrics, so that there is no color on the silk.

FAQ

FAQ

What is the purpose of dyeing auxiliaries?
Dyeing auxiliaries includes dye fixing agents, cationizing agent, dispersing & leveling agents etc. They help in stabilizing the dyeing bath to improve the exhaustion, achieve level dyeing and improve fastness properties.
What are the causes of stains in cylinder dyed fabrics?
The chemical raw materials are not uniform enough; the gray cloth is not clean; the hardness of the water is too high; the heating rate of dyeing is not properly controlled; the use of dyeing auxiliaries is improper; the quality of the dye is poor.
How to choose textile printing and dyeing auxiliaries correctly?
Have a basic understanding of the solubility of additives and their stability to hard water and metal ions; the acid and alkali resistance of additives must be tested; the ionicity of additives must be grasped; do not arbitrarily reduce the amount of additives ; Additives must be dissolved and diluted before adding to the finishing solution.
What is the difference between ash substitute and soda ash?
In the dyeing process, soda ash only acts as a dyeing accelerator, and the intensity of sewage treatment is increased. Substitute alkali is a new type of environmentally friendly product developed for the high cost of soda ash and trisodium phosphate in the exhaust dyeing of reactive dyes, the inconvenience of use, the instability of color fixation with caustic soda, and the dark shade. While reducing the cost of alkaline agents, it can also improve the first-time success rate of dyeing and significantly reduce the overall cost of dyeing.
What are the dyeing auxiliaries to improve color fastness?
Fixing agent, Wet Rubbing Fastness Improver agent, Dispersion accelerator.
