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!

line-height:25px;};As a large developing country, it is developing fast. A lot of industrial waste is inevitable. There are countless waste paints. Paints are common in construction and decoration, and even in all walks of life. Arrived.
But at present, many waste paint treatment methods are recycling, the usual method is burning, but we all know that the burning of waste paint will cause great pollution to the atmospheric environment, but random dumping will also cause pollution to land resources. It can also cause a fire. So how to deal with the recycling of waste paint? Many paints contain substances. Burning without treatment and random stacking will greatly threaten people’s lives, property and health. In fact, we should consider the development of the road. Waste paint itself is something that can be used again, but we preconceived that the waste is unusable.
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 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.

Substances that can significantly pollute the environment, such as benzene, and the emission of hazardous waste gas pollutants (HAPs), as a solvent system coating, it also has good coating and construction performance, and can be constructed under low temperature conditions in winter. In addition, due to the low solubility of the solvent in the coating system, it will not cause corrosion, so it is easy to recoat. It can also be used for spraying materials that are easily corroded by solvents. 2. Number of components Polyester paint (PE): 3-4 components, 3 components are non-wax polyester paint, 4 components are wax type polyester paint. Component one is the benzene solution of unsaturated polyester (main agent); component two is the initiator (also known as curing agent, hardener, common name white water);
