Embodiment 1

[0026] A kind of tensio-active agent that one-bath process of woven fabric destaining is used, is made up of following components by weight percentage:

[0027] Sodium stearate accounts for 14.5% of the total weight, sodium dodecylbenzenesulfonate accounts for 23.4% of the total weight, nonylphenol polyoxyethylene ether accounts for 5.6% of the total weight, and the diffusing agent MF accounts for 37.8% of the total weight. The balance is water. Among them, nonylphenol polyoxyethylene ether is an adduct of nonylphenol and ethylene oxide, the hydroxyl value of polyoxyethylene ether is 85±3mgKOH / g, and the pH value is between 6-7, it is colorless Transparent liquid. Diffusion agent MF is sodium methylene bismethyl naphthalene sulfonate (C 23 h 18 o 6 S 2 Na).

[0028] The concrete preparation method of this tensio-active agent is as follows:

[0029] Calculated on the basis of 1kg of surfactant: 0.145kg of sodium stearate, 0.234kg of sodium dodecylbenzenesulfonate, 0.056k...

Abstract

The invention discloses a surfactant for a woven fabric dye-bath retreat process and a preparation method thereof, wherein the surfactant comprises the following components in percentage by weight: 10-20 percent of sodium stearate, 20-30 percent of sodium dodecyl benzene sulfonate, 3-8 percent of polyoxyethylene nonyl phenyl ether, 30-40 percent of dispersing agent MF and the balance of water. The preparation method comprises the following steps of: adding water into the sodium stearate for dilution so as to prepare a solution with the concentration of 5-8 percent; then, adding the solution into a reaction kettle, and heating to the temperature of 70+/-5 DEG C; sequentially adding the sodium dodecyl benzene sulfonate and the polyoxyethylene nonyl phenyl ether, fully stirring and mixing; and finally, cooling to the temperature of 35+/-5 DEG C, adding the dispersing agent MF after foams naturally disappear, fully stirring and mixing to prepare the surfactant. The product can prevent the reattachment of slurry and impurities, and improve the dyeing quality.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing processing, in particular to a surfactant used in a one-bath process of destaining woven fabrics and a preparation method thereof. Background technique [0002] The one-bath de-dyeing process of woven fabrics is to complete the desizing and dyeing processes in the pre-treatment process of traditional woven fabrics in the same treatment bath. In the desizing process of the one-bath destaining process of woven fabrics, although the special-effect same-bath desizing agent can dissolve the size in the water bath, it is inevitable that some of the size will fall off naturally due to the movement of the fabric, and the fabric In the process of weaving and transportation, some impurities will inevitably adhere to the surface and cannot be removed during the desizing process. In the destaining one-bath process, desizing and dyeing are carried out in the same water bath, and the size or impurit...
