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's take a look together!

Organic pigments have bright colors, strong tinting power, low density and sex. Organic pigments look looser, while inorganic pigments are heavier. .articleContenta{color:#;font-size:14px;line-height:25px;};Painting problems and solutions The reason is that the product is smooth or the product is not soaked in place, or the quality of the paint is not good, which will also cause the paint to fall off after being sprayed on. 2. The paint blisters. First, the bubble punctures. If there is water coming out, it means that moisture has penetrated under or behind the paint layer. When exposed to the sun, the water evaporates into steam, which will top the paint leather into bubbles. At this time, First use hot air spray to remove the bubbling paint, let the product dry naturally, then apply the primer, and then repaint the entire repaired surface.
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 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 without fixing treatment.

The thinner evaporates too fast or the thinner contains water.
3. The coating surface is contaminated or not cleaned and dried. 4. The compressed air contains moisture. .Three. Solution------Solution1. Strengthen the air dehumidification function in the painting area and reduce the relative humidity. 2. Strengthen the high temperature forced drying in the drying room of the coating line to reduce the degree of influence on the coating. 3. The boiler compresses air and discharges water regularly to prevent water from directly polluting the surface through spraying. 4. Choose a thinner suitable for seasonality. Such as winter type and summer type. 5. When the relative humidity is high, an appropriate amount of anti-white water should be used, such as not more than 3% BCS, and thick coating should be avoided.
