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!

Some manufacturers (such as Wanbao Waste Tire Processing Factory in Lishui City, Zhejiang) implemented it, but the processing volume was not large. Two-component polyurethane coating has the advantages of low film forming temperature, strong adhesion, good abrasion resistance, high hardness, chemical resistance, and good weather resistance. It is widely used as industrial protection, wood furniture and automotive coatings. Water-based two-component polyurethane coatings combine the high performance of two-component solvent-based polyurethane coatings with the low VOC content of water-based coatings and become a research in the coatings industry. The water-based two-component polyurethane coating is composed of a water-based polyol containing -OH groups and a low-viscosity polyheterogeneous curing agent containing -NCO groups. The film performance is mainly determined by the composition and structure of the coating.

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 to occur. 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.

2. Check if the paint is contaminated, replace it immediately. 3. Inventory and eliminate the pollution sources within the paint line, such as butter, wax or contaminated hands, containers, clothing and rags.
4. The compressed air is filtered and the compressor drains water regularly. 5. The coating line should be fully ventilated and exhausted to reduce the possibility of air pollution. 6. Check the paint quality and refuse to use expired or deteriorated paint. 7. When fish eyes occur, stop the line immediately, clean the site and add no more than 3% leveling agent to the coating. 8. Products with fish eyes should be sanded before rework. (5) Orangepeel 1. Symptoms-The surface of the Symptom coating film shows wrinkles similar to orange peels.

To sum up, the content mentioned above is the related matters shared by the recycled fuel manufacturers.
