Problems solved by technology

[0008] Although a variety of fabric desizing agents are disclosed in the above-mentioned invention, the performance of the product is single, and the hair effect and feel of the fabric after the desizing agent are not paid attention to, so it is necessary to design a desizing treatment that has a good effect. It is a desizing agent that combines excellent wool effect, good hand feeling and refining functions

Abstract

The invention aims at overcoming the defects in the prior art, and provides a desizing agent with the advantages that the desizing effect is good; the damage on fabrics is small; the treated fabrics have a good wool effect, hand feeling and whiteness; in addition, the seepage performance and the dispersion performance are good; the refining effect is achieved. The invention provides the desizing agent, which is prepared from the following ingredients in parts by weight: 2 to 8 parts of sodium hydroxide, 15 to 20 parts of nonylphenol polyoxyethylene ether, 5 to 10 parts of dodecyl trimethyl ammonium chloride, 5 to 10 parts of glyceryl cocoate, 2 to 7 parts of coconut acid monoisopropanolamide, 6 to 12 parts of isocetyl stearate, 1 to 3 parts of polydimethylsiloxane, 2 to 6 parts of sodium laurate, 4 to 8 parts of glycol, 1 to 4 parts of polyvinylpyrrolidone, 2 to 6 parts of ammonium persulfate, 1 to 4 parts of potassium chloride, 1 to 4 parts of nano-zinc oxide, 2 to 5 parts of ethylhexyl palmitate, 8 to 15 parts of propyl alcohol and 25 to 35 parts of water. The desizing rate of the fabrics treated by the desizing agent provided by the invention is 96.1 percent or higher; in addition, the fabrics cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliaries, and in particular relates to a desizing agent and a preparation method thereof. Background technique [0002] During the manufacture of fabrics, the warp yarns will be repeatedly subjected to friction and tension during the weaving process, causing the yarns to fluff and break. Warp yarns are usually sized prior to manufacture. However, the existence of warp sizing has brought a lot of trouble to the subsequent dyeing and finishing of fabrics. It will not only contaminate the finishing fluid, but also consume dyes, and even hinder the contact between dyes and fibers, directly affecting the quality of printing and dyeing. Desizing must be done before printing and dyeing. Desizing is the basis of fabric pretreatment, and most of the size on the original fabric must be removed for subsequent processing. [0003] Commonly used traditional desizing methods include al...
