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!

Pure PA emulsion has the defects of poor wear resistance, water resistance and chemical resistance, high solid content, and limited application range. PU and PA have complementary effects in nature. PUA composite emulsion has the advantages of both, it has the characteristics of wear resistance, corrosion resistance and brightness, elasticity, water resistance, good mechanical properties, and good weather resistance. Therefore, it is known as the third generation of waterborne polyurethane and has become a development of today’s coatings. trend. The coating can make up for the lack of performance of water-based coatings and maintain the superior performance of solvent-based coatings. It can also affect the impact of paint on the environment. Taking into account both performance and environmental protection, this problem is better solved. The coating system uses petroleum-based low-polarity solvents with low odor and low properties as diluents.

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, and no fixation treatment is required.

It can be disposed of in a harmless manner. There is no uniform standard for the treatment price, and the price is usually determined according to the quality of the waste paint, and the quantity is high and the price is high. .articleContenta{color:#;font-size:14px;line-height:25px;};Pigments are soluble and insoluble, and there are differences between inorganic and organic. Inorganic pigments are generally mineral substances. Humans have known for a long time that inorganic pigments are used to paint and paint the body on rock walls using colored soil and ores. Inorganic pigments include cadmium series, cadmium series, iron oxide series, and the newly emerging environmentally friendly color inorganic composite pigments. Domestic organic pigments are generally derived from plants and marine animals, such as azure blue, garcinia, and ancient Roman extracts from shellfish. Purple.
