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!

Therefore, we must pay attention to the purchase of these liquid chemical raw materials. There is also that when we produce these chemical raw materials, we must pay attention to building a chemical raw material market in some empty places with few people. After some chemical raw materials market closed down, they no longer proceed, thus neglecting the purchase of chemical raw materials and dyes. If these waste chemical raw materials are not purchased, the harm brought by us will be unimaginable. We must pay attention to the chemical raw materials. The purchase of dyestuffs is paid more attention, especially the hazardous liquid chemical raw materials. .articleContenta{color:#;font-size:14px;
Applicable technical guide: used for dyeing nylon fibers with acid dyes, and then processing 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 the nylon fiber is dyed with the acid dye, it is washed with soft water, and then the dyed material is post-treated with NBS at pH 4.5, 70-80°C, 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 treatment with saturated steam, 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

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, 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. 3.
In summary, the contents mentioned above are related matters shared by recycled fuel manufacturers.
