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!

Therefore, we must pay more attention to the purchase of these liquid chemical raw materials. There is also that when we produce these chemical raw materials, we must pay attention to building a chemical raw material market in some empty places with few people. After some chemical raw materials market closed down, they no longer proceed, thus neglecting the purchase of chemical raw materials and dyes. If these waste chemical raw materials are not purchased, the harm brought by us will be unimaginable. We must pay attention to the chemical raw materials. Dyestuffs are paid more attention, especially the hazardous liquid chemical raw materials. .articleContenta{color:#;font-size:14px;

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 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.

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 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 third component is an accelerator (common name blue water); the fourth component is a 4% paraffin benzene solution.
Polyurethane paint (PU): 1-3 components, one-component and two-component, the latter also has a diluent when mixing the paint. The general paint ratio is: main agent: curing agent: diluent 1:0.5 -1:0.5-1.57. Curing conditions and mechanism Polyester paint (PE): anaerobic polyester needs to be cured with oxygen isolation (wax sealing method), new air-drying polyester does not need to be cured with oxygen isolation, unsaturated polyester and benzene Under the action of initiator accelerator, free radical polymerization takes place, cross-linking and curing into a film. Polyurethane paint (PU): it can be air-dried at room temperature or at low temperature (50°C).
