    Summary. Hello dear, hydrogen peroxide (H2O2) and dyes may react during the dyeing process, resulting in discoloration or affecting the dyeing effect. To solve this problem, you can do the following:

    1.Reduce reactions: Try to avoid direct contact between hydrogen peroxide and dyes, and reduce the likelihood of reactions between them by adding buffers, stabilizers, or using separate dye solutions.

    2.Staged staining: The staining process is divided into two stages.

    In the first stage, a mixture of hydrogen peroxide and dye is diluted and pre-stained at low temperatures. In the second stage, the pre-dyed dye is transferred to the conventional dyeing process to reduce the reaction between the hydrogen peroxide and the dye. 3.

    Increase the temperature: Adding some accelerators or increasing the temperature of the reaction system to the mixture of hydrogen peroxide and dye can help reduce the reaction between hydrogen peroxide and dye.

    4.Choose appropriate dyes: choose dyes with good stability, such as dyes with strong antioxidant and hydrolysis resistance, which can reduce the reaction between hydrogen peroxide and dyes.

    5.Pretreatment of dyes: Before dyeing, pre-treatment of dyes, such as the use of reducing agents or antioxidants in hail, can help improve the stability of the dye and reduce the possibility of its reaction with hydrogen peroxide.

    6.Control the concentration of hydrogen peroxide: During the dyeing process, appropriately reducing the envy of hydrogen peroxide can reduce the reaction between hydrogen peroxide and the dye.

    Summary. Hello, dear, what is the dye that adds hydrogen peroxide to color, the dye that is colored with hydrogen peroxide is usually sulfuric acid dye, which can be used to dye various fibers, including cotton, linen, silk, wool and other types of fibers, so that the color of the object looks more beautiful.

    Direct dyes resistant to hydrogen peroxide include those varieties dyed by pure cotton and one bath dyeing.

    Hello, dear, what is the dye that adds hydrogen peroxide to color, the dye that is colored with hydrogen peroxide is usually sulfuric acid dye, and the nuclear state can be used to dye various or cover fibers, including cotton, linen, silk, wool and other types of fibers, so that the color of the object looks more beautiful.

    Hello, hydrogen peroxide resistant direct dyes have those varieties dyed pure cotton by one bath dyeing, hydrogen peroxide resistant direct dyes are: diazo dye: is a kind of dye containing diazo groups, which can be used for dyeing cotton, flax, silk and other fibers, with good color fastness.

    Carbamate dyes: This dye has high brightness and good color fastness, especially suitable for dyeing dark cotton fabrics. Azo dyes:

    This dye has good stability to light and alkalinity, and is suitable for dyeing light-colored cotton fabrics. Direct dye: This dye has good washing and light resistance, and is suitable for dyeing light-colored cotton fabrics.

    At best, it is necessary to dye pure cotton in one bath, and it is necessary to choose the right dye according to the specific dyeing process and dye type. Commonly used one-bath dyes include diazo dyes, vat dyes, direct dyes, etc. When choosing a dye, it is necessary to take into account factors such as dyeing effect, color fastness, dyeing speed, etc.
