Abstract

The invention discloses a method for preparing a textile printing thickening agent. The method includes the following steps that firstly, a thickening agent reaction reagent is prepared, and the reaction reagent contains acrylic acid, methacrylic acid, p-dioxanone and sodium sulfate; secondly, a catalyst is added into the reaction reagent in the first step, the reaction temperature is controlled to be 95 DEG C, the mixture is continuously stirred and reacts for 1.5 h and is gradually cooled to room temperature; thirdly, a 40% sodium hydroxide solution is used for adjusting the pH value of the reaction products in the second step to be 5-5.5, and the required textile printing thickening agent is finally obtained. Compared with the prior art, the method has the advantages that reaction speed is easy to control, and the reaction products are environmentally friendly and free of pollution, and the method is particularly suitable for industrial production.

Description

Technical field: [0001] The invention relates to the technical field of textile materials, in particular to a preparation method of a textile printing thickener. Background technique: [0002] Textile printing refers to the process of limited dyeing on the predetermined area of ​​the textile. Through the preparation of color paste, visualization and color fixation, the color paste is finally fixed within the predetermined range of the textile to produce a specific pattern. In order to blur the edge of the pattern due to the seepage of the textile color paste during the firming process, it is necessary to strictly control the rheological properties of the color paste during the textile printing process. If the rheology of the color paste is too poor, it is not easy to apply on the textile The desired pattern is formed on the surface; on the contrary, if the rheology of the color paste is too strong, it is easy to bleed during the firming process and cause the edge of the patt...
