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 whether 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, the bottom layer is not fully dried, so 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: It is applied to dye nylon fiber with acid dye, and then process the dyed product. 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 by weight of cloth) After dyeing nylon fiber with TELONL, SUPRANOL or other selected acid dyes, rinse it with soft water, and then dye the dyed product with NBS at PH4.5, 70-80°C, 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-processing, it will cause precipitation and impair the NBS effect (before fixing, it can be washed with soaping agent to prevent abnormal occurrence). 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 has a rough feel, which will affect its subsequent weaving operations. Therefore, for this kind of dyeing, only dyes with higher wet fastness should be selected for dyeing, and no fixation treatment is required.

And because these dyes for dyeing clothes are generally liquid chemical raw materials, it is very troublesome to purchase these liquid chemical raw materials. Let's talk about the harm that this liquid chemical raw material will bring to us in detail. Liquid chemical raw materials are all fine chemical raw materials that require a variety of chemical agents to be formulated. This liquid chemical raw material will cause certain harm to the body when it is used, so be sure to pay attention to the purchase of this liquid chemical raw material after use. Because the flow direction of this liquid chemical raw material is not directional, it will cause certain harm to the surrounding environment. Not only some crops will not grow, but our own health will also be harmed to a certain extent.
