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!

The advantage of chemical raw material dye recovery is that it can promote the reuse of resources. You can only choose a suitable recycling chemical raw material manufacturer according to the actual situation. When looking for a manufacturer, you still need to consider carefully, so that you can clearly know which manufacturer’s recycling price is In any case, whether the recycling process meets the standards is extremely important. The composition of manufacturers of recycled chemical raw materials is actually very easy to understand, mainly recycling some chemical raw materials for secondary sales. The raw materials purchased by some companies may not be used up, so they can be recycled through these recycling companies to realize resource reuse in this way. This is a new method that is worth choosing. It is not only conducive to the return of funds, but also conducive to resource recycling. use.
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 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.
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.

One-component waterborne polyurethane coating is a type of coating that uses waterborne polyurethane as the base material and water as the dispersion medium. The waterborne polyurethane coating modified by crosslinking has good storage properties, coating film mechanical properties, water resistance, solvent resistance and aging resistance, and has similar properties to solvent-based polyurethane coatings. It is an important development of waterborne polyurethane coatings. direction. Light-curing waterborne polyurethane coatings use high-intensity radiation such as electron beam radiation and ultraviolet radiation to initiate cross-linking and curing of a low-activity prepolymer system, mainly in the form of ultraviolet curing. First, use unsaturated polyester polyol to prepare prepolymer, then introduce particle gene by conventional method, and prepare an aqueous polyurethane dispersion with double bonds on the main chain after hydrophilic treatment. Alkoxy ester monomers, photosensitizers and other additives are mixed to obtain light-curing waterborne polyurethane coatings.
