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!

2. The root cause of the reason-Reason1. The viscosity of the coating is too high, or the spraying is too much.
2. The thinner volatilizes too fast, which makes the coating film fast and cannot be leveled in time. 3. The pressure of the compressed air is not enough, and the paint cannot be foggy. 4. Use expired or deteriorated paint. 5. The paint is not fully stirred before use, and the paint and thinner are fully mixed
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 it 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 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. 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-treatment, it will cause precipitation and impair the NBS effect (before fixing, it can be washed with a soaping agent to prevent abnormalities). 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.

6. Use the wrong or deteriorated thinner. 7. The hardener of the two-component coating is added too much.
Three. Solution——Solution1. Strengthen the sanding quality of the object. 10. Existing products must be ground before recoating. (3) Bubbles 1. Symptoms: The surface of the Symptom coating shows bubbles of different sizes. 2. The root of the reason is Reason 1. The viscosity of the coating is too high, or the spraying is too much. 2. The temperature difference between the inside and outside of the drying room is too large, or the temperature of the drying room is too high. 3. The wood products with deep pipes are not well filled, such as OAK. 2. Check whether the moisture content of the wood is below 10%.
To sum up, the content mentioned above is the related matters shared by the recycled fuel manufacturers.
