Embodiment 1

[0055] The present invention has prepared sodium polytranscarboxylate, and is used for cotton reactive dye dyeing and washing, specifically comprises the following steps:

[0056] (1) Add 75g of distilled water, 13g of fumaric anhydride, and 13g of acrylic acid into the reaction flask, start stirring, and add 37g of acrylic acid and 30g of distilled water into the separatory funnel after dissolving # .

[0057] (2) When the temperature of the reactants in the reaction bottle rises to 60°C, add 1 / 3 of the solution of 15 g of sodium persulfate and 30 g of distilled water into the reaction bottle, and add the rest into the separatory funnel 2 # .

[0058] (3) After the reactants in the reaction bottle were kept at 60°C for 0.5h, the temperature was raised to 76°C to start exothermic reaction and continued to heat up to 93°C, and then cooled to 84°C, and the separatory funnel 1 was removed after 1.5h. # , separatory funnel 2 # The middle material was added into the reaction bot...

Abstract

The invention belongs to the field of synthesis of functional polymers and dyeing processing of textiles, and in particular relates to a preparation method of poly-trans-sodium carboxylate and an application thereof. The preparation method comprises the following steps: carrying out polymerization under initiation of sodium persulfate to generate poly trans-carboxylic acid by taking trans-butene anhydride and acrylic acid as monomers; and neutralizing the poly trans-carboxylic acid with sodium hydroxide to obtain the poly-trans-sodium carboxylate. By applying the poly-trans-sodium carboxylateto dyeing cotton cloth with a reactive dye, surface dyeing on the dyed cotton cloth is washed and the color fastness to rubbing and the anti-adhesion color fastness of the dyed cotton cloth are good.The poly-trans-sodium carboxylate can chelate calcium ions in water, and is few in foam in a washing process, so that stains on the dyed cotton cloth are prevented. Therefore, the washing method provides a novel path for solving the problem that the anti-adhesion color fastness of the dyed cotton cloth washed by sodium dodecyl benzene sulfonate is poor and provides a new concept for solving the problem that a lot of foam is generated in the washing process by sodium dodecyl benzene sulfonate, the sodium dodecyl benzene sulfonate cannot be chelated with calcium ions in water, and the dyed cotton cloth generates stains easily, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of functional polymer synthesis and textile dyeing processing, and in particular relates to a preparation method and application of sodium polytranscarboxylate. Background technique [0002] In the washing and floating color of cotton cloth dyed with reactive dyes, traditional detergents use sodium dodecylbenzene sulfonate as the main component. The binding force of the fiber, so that the floating color is separated from the fiber. The reactive dye molecule contains a sulfonic acid hydrophilic group, and the floating color and sodium dodecylbenzenesulfonate form an association, and there are also some floating colors in free water. Due to the affinity between cellulose fiber and floating color, the floating color in water will dye the fiber when washing the floating color, especially the dyeing rate of undyed fiber is high. The association formed by sodium dodecylbenzenesulfonate and the floating color is not very s...
