5. The reason for the loss of gloss is that the primer is not applied, or the primer, that is, the inner paint, is directly applied before it is dried. As a result, the glossy paint does not absorb and loses its luster. Some lacquer quality problems are also a cause. The solution is to use dry and wet sandpaper to wipe off the old paint, brush off the sanding dust, wipe the surface with a clean damp cloth, and re-spray the paint after it dries. It should be noted that the temperature is very high. When spraying paint in a low environment, the paint film will lose its luster when it dries. 6. Whitening In the environment of low temperature or high humidity, the sprayed paint is easy to whiten. One is to increase the anti-whitening agent; the other is to reduce the humidity in the spray booth. 7. Particles appear in the product after particle spraying. The main reason is that there is dust in the spray booth environment. Keep the spray booth clean;
Applicable technical guide: applied 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.
To
Concentration of acid dye: 1.0-2.0% (owf) NBS (calculated based on cloth weight) After dyeing nylon fiber with TELONL, SUPRANOL or other selected acid dyes, wash 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 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-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 feels very rough, 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.
