Surfactant for woven fabric dye-bath retreat process and preparation method thereof

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...

Problems solved by technology

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 During weaving and transportation, it is inevitable that some impurities will 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 sizing or impurities that dissolve or fall off in the water bath may reattach, causing fabric dyeing defects.
