Embodiment 1

[0024] A method for three-dimensionally judging the fineness of paste printed patterns, comprising the following steps:

[0025] (1) According to the printing paste prescription: 1% K-type Argosol Red P-4B, 5% urea, 1% resist salt S, 1% sodium bicarbonate, 70% original paste. Adjust the viscosity of the color paste to 10000±1000mPa·s (25±1°C, No. 4 rotor, 30r / min, measured by a rotational viscometer).

[0026] On a flat screen of 180 mesh, the diameter of the magnetic rod is 8mm, the speed of the vehicle is 6m / min, and the magnetic force is 3 # Cotton fabrics were printed with reactive dyes under certain printing conditions. Print a right-angled wedge-shaped pattern with a length of 100mm and a height of 2mm on the fabric.

[0027] (2) After drying the printed wedge-shaped pattern, measure the actual length and height of the wedge-shaped pattern obtained on the fabric;

[0028] (3) Calculate the fineness of the wedge shape to judge the fineness of the printed pattern.

Abstract

The invention relates to a three-dimensional rapid judgment method for the fineness of a thickener-printed flower form. The method comprises the following steps: (1) preparing printing paste and printing a right-angle wedge-shaped pattern with a length of 100mm and a height of 2mm on a piece of fabric; (2) drying the printed right-angle wedge-shaped pattern, and measuring the actual length and height of the right-angle wedge-shaped pattern on the fabric; (3) calculating the right-angle wedge-shaped pattern, so as to judge the fineness of the printed flower form. In an evaluation method provided by the invention, the fineness of a wedge shape needs to be more than 70%; the more the value of the fineness is, the higher the fineness of the printed flower form is; the printing property of the fine flower form prepared from a thickener is relatively good; the invention provides the evaluation method for the fineness of the thickener-printed flower form, which has the advantages of being relatively high in quantification, simple and easy to operate; the printing property of the fine flower form of a thickener can be accurately reflected.

Description

technical field [0001] The invention belongs to the field of fabric printing methods, in particular to a method for three-dimensionally judging the fineness of patterns printed with paste. Background technique [0002] With the advancement of high-mesh screen printing and printing technology, the printed pattern tends to be more refined, and strives to accurately show the pattern on the fabric that conforms to the original design spirit. The fineness of the pattern is high, and the pattern printed on the fabric is closer to the pattern originally designed. [0003] At present, the method of judging the fineness of paste pattern is limited to the traditional method, and there is no quantitative unified standard. It has been reported in the literature that the fineness of printed patterns is evaluated by visual evaluation method. There are also reports in the literature that the sharpness obtained by printing wedge-shaped patterns, that is, the ratio of the actual wedge-shap...
