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 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 worth choosing, which is not only conducive to the return of funds, but also conducive to resource recycling. use.
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℃, 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.
