Repair Agent CY-516B Performance and Characteristics

1. It has good transferability and can effectively solve and repair all kinds of dyeing of polyester and its blended fabrics, especially polyester fabrics such as suede and pongee, which can effectively prevent the repair of white spots. After the repair, the color light is basically unchanged.

2. It can also be used as a polyester leveling agent. The special active agent component in the component can play a role in retarding and preventing the secondary coagulation of the dye during the low temperature stage of dyeing, and can play a strong role in promoting the dyeing at high temperature. The dyeing of the blended fabric not only improves the leveling property, but also increases the color yield.

3. It is more vivid in dyeing.

4. It is used for dyeing polyester cheese, which can effectively avoid the problem of color difference between the inner and outer layers of the cheese.

  • 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.
