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!

Component three is an accelerator (common name blue water); component four is a 4% paraffin benzene solution.
Polyurethane paint (PU): 1-3 components, single-component, two-component, the latter also has a thinner when mixing the paint, the general paint ratio is: main agent: curing agent: thinner 1:0.5 -1:0.5-1.57. Curing conditions and mechanism Polyester paint (PE): anaerobic polyester needs to be cured with oxygen isolation (wax sealing method), new air-drying polyester does not need to be cured with oxygen isolation, unsaturated polyester and benzene Under the action of initiator accelerator, free radical polymerization takes place, cross-linking and curing into a film. Polyurethane paint (PU): it can be air-dried at room temperature or at low temperature (50°C).
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.
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.
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.
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.

Incineration: It can solve the problem of land occupation, but if its value is not fully utilized, it will also cause serious air pollution. Many cement plants, power plants, paper mills, steel plants, etc. in the United States, and Western Europe use waste tires as fuel. According to statistics, waste tires account for about 50% of the total waste tires. This kind of recycling method cannot make waste rubber products play a good role in the field of polymer material recycling, and in the end it simply consumes precious resources. Existing problems: The current problem is that the cost of waste rubber cracking equipment is high, the separation and purification process of cracked products such as heavy oil is difficult to control, and the quality of crude carbon black is poor, and further processing and improvement are needed, so the current effect is not obvious. .
