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!

Solution——Solution1. The viscosity of the coating is appropriate, and the spraying should be performed according to the standard , Don't overcoat.
2. The temperature of the drying room is within the proper range, generally between 35℃-40℃. 3. Strengthen the filling of wood conduits. 4. Replace the diluent suitable for the season and climate. . (Recycling paint) 5. When spraying multiple times, strengthen the drying time of the bottom layer. 6. The pressure of the compressed air is within the standard range. 7. To filter the air and compress the air, the air compressor should be timed. 8. Test the moisture content of wood and control it below 10%. 9. Products with bubbles must be carefully ground with sandpaper before being repaired and recoated.
Applicable technical guide: It is used 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.
酸性染料使用浓度：1.0-2.0%(owf)NBS(以布重计算)以TELONL，SUPRANOL或其它选择 After dyeing the nylon fiber with the acid dye, wash it with soft water, and then the dyed product is post-treated with NBS at pH 4.5, 70-80℃, 20-30 minutes.
注意事项：如增加NBS三分之一用量，也可藉热空气方式完成固色作业。 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 to occur. Any precipitation that has occurred can be easily dissolved by adding a small amount of ammonia.
如果在后处理中存在非离子添加剂，则会引起沉淀并损害NBS效果（定影前，可以用皂洗 Agent washing to prevent abnormalities from occurring). 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 without fixing treatment
