Recycling dyes manufacturer Bokai Chemical Trade Recycling Company said that acid dyes are widely used in fabric dyeing and people often use them, but the color fastness of these dyes is usually very poor. Recycled dye manufacturers say that some users repair dyes that meet the standards. However, we need to pay attention to certain things that need to be paid attention to when fixing dyes. Let us take a look!

3. Check whether the paint has expired or deteriorated.
4. Check if the thinner is used incorrectly or has deteriorated. 5. When using two-component paint, be sure to follow the standard operation. 6. When spraying multiple times, the drying time between coatings should be sufficient. 7. The viscosity of the paint is at an appropriate level. 8. Before drying at high temperature, be sure to let the solvent in the paint have sufficient time to evaporate. 9. The temperature difference between the inside and outside of the drying room should not be too large. 4. The volatilization speed of the thinner is too fast. 5. When spraying repeatedly, if the bottom layer is not fully dried, spray continuously. 6. The pressure of compressed air is too high. 7. The compressed air contains moisture. 8. The moisture content of wood is too high. three.

Applicable technical guide: applied to dye nylon fibers with acid dyes, and then process the dyed products. After dyeing nylon fibers with acid dyes, the dyed product can be treated with NBS to improve its wet fastness, especially to water, sea water, washing, and sweat. The fastness can be significantly improved. Similar to all such additives, The degree of improvement in fastness varies depending on the dyeing method and fiber.

To

Concentration of acid dye: 1.0-2.0% (owf) NBS (calculated based on cloth weight) After dyeing nylon fiber with TELONL, SUPRANOL or other selected acid dyes, wash it with soft water, and then dye the dyed product with NBS at PH4.5, 70-80℃, 20-30 minutes, post-treatment.

To

Note: If you increase the amount of NBS by one third, you can also use hot air to complete the fixation operation. The wet fastness has been improved to a considerable extent, but the temperature should not exceed 180-185℃. If the temperature exceeds, or the saturated steam is treated, it will affect the NBS. When dissolving or diluting NBS, it is necessary to prevent direct contact with concentrated acetic acid. The contact of NBS with concentrated acetic acid will cause precipitation. Any precipitation that has occurred can be easily dissolved by adding a small amount of ammonia.

To

If there are non-ionic additives in the post-treatment, it will cause precipitation and impair the NBS effect (before fixing, it can be washed with a soaping agent to prevent abnormalities). If the dyed product is coated with PU or film in the later process, do not fix it with NBS, otherwise it will affect its adhesion effect. The nylon batting that uses NBS as a post-treatment feels very rough, which will affect its subsequent weaving operations. Therefore, for this kind of dyeing, only dyes with higher wet fastness should be selected for dyeing, without fixing treatment.

Pure PA emulsion has the defects of poor wear resistance, water resistance and chemical resistance, high solid content, and limited application range. PU and PA have complementary effects in nature. PUA composite emulsion has the advantages of both, it has the characteristics of wear resistance, corrosion resistance and brightness, elasticity, water resistance, good mechanical properties, and good weather resistance. Therefore, it is known as the third generation of waterborne polyurethane and has become a development of today’s coatings. trend. The coating can make up for the lack of performance of water-based coatings and maintain the superior performance of solvent-based coatings. It can also affect the impact of paint on the environment. Taking into account both performance and environmental protection, this problem is better solved. The coating system uses petroleum-based low-polarity solvents with low odor and low properties as diluents.

In summary, the contents of the above are related matters shared by the recycled fuel manufacturers.
