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!

(4) Fisheye 1. Symptoms----- When the Symptom topcoat is sprayed, there are pitting spots similar to fisheyes on the surface of the coating.
2. The root of the cause-----Reason1. There is oil or wax on the surface of the product. 2. The paint contains oil or wax. 3. The environmental pollution of the coating line, the air contains oil or wax, etc. 4. Contaminated rags are used. 4. Use expired or deteriorated paint. 5. There is water or paint in the compressed air. Three. Solution——Solution1. Before coating the product, clean the surface with a thinner such as toluene (Toluene), (Xylem) or (Acetone).
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 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

Some manufacturers (such as Wanbao Waste Tire Processing Factory in Lishui City, Zhejiang) also implement it, but the processing volume is not large. Two-component polyurethane coatings have the advantages of low film-forming temperature, strong adhesion, good abrasion resistance, high hardness, chemical resistance, and good weather resistance. They are widely used as industrial protection, wood furniture and automotive coatings. Water-based two-component polyurethane coatings combine the high performance of two-component solvent-based polyurethane coatings with the low VOC content of water-based coatings and become a research in the coatings industry. The water-based two-component polyurethane coating is composed of a water-based polyol containing -OH groups and a low-viscosity polyheterogeneous curing agent containing -NCO groups. The film performance is mainly determined by the composition and structure of the coating.
In summary, the content mentioned above is the related matters shared by the recycled fuel manufacturers. Bokai Chemical Trade Recycling Company supports on-site chemical raw material recycling, recycling of dyes, recycling of paint raw materials, high-priced recycling, etc. For business, please call for consultation if you have any needs in this regard!
