Embodiment 1

[0047] This embodiment provides a printing paste, which is composed of the following raw materials in weight percentage: 25% sodium alginate, 15% additives (the weight ratio of sodium hexametaphosphate: sodium sulfate is 0.7:3) and 60% cmc.

[0048] Use the method provided by the invention to detect the cmc content in the above-mentioned printing paste, the steps are as follows:

[0049] S1, first beat the printing paste solution with pure water, the beating process is as follows:

[0050] Weigh 500g of printing paste solution with a concentration of 6%, put it in a beating mixer, set the rotation speed of the agitator to 600r / min, and stir for 1.5h, take it off, let it stand until no bubbles overflow, and obtain a beating solution ;

[0051] S2, the beating solution obtained in S1 is enzymatically hydrolyzed by enzymatic hydrolysis, and the enzymatic hydrolysis process is as follows:

[0052]Add 0.09 g of cellulose compound enzyme to the beating solution obtained in S1, the...

Embodiment 2

[0064] A kind of detection method of cmc content in printing paste for printing and dyeing, the steps are as follows:

[0065] S1, first beat the printing paste solution with pure water, the beating process is as follows:

Abstract

The invention provides a detection method for cmc (Carboxymethylcellulose sodium) contents in printing paste used for printing and dyeing. The detection method comprises the following steps that: S1:pulping printing paste solution by pure water; S2: carrying out enzymolysis on the pulped solution obtained in S1 by an enzymolysis method; and S3: adopting a backward induction method or an exponential function method to calculate cmc contents in the printing paste, wherein the printing paste comprises thickening agent and additive, the thickening agent consists of cmc and sodium alginate, and the additive consists of one or multiple of anhydrous sodium sulphate and sodium hexametaphosphate. The detection method for the cmc contents in printing paste used for printing and dyeing has the advantage of high calculation speed and provides an optimization foundation for printing and dyeing paste ingredient contents.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, in particular to a method for detecting CMC content in printing paste for printing and dyeing. Background technique [0002] During the use of printing paste, especially the printing paste obtained by purchasing, different weaving and dyeing effects will usually appear due to different fabrics, and even weaving and dyeing defects will occur, resulting in the printing paste not being able to The disadvantage of waste of printing paste due to use, and the disadvantage of high weaving and dyeing costs caused by the purchase of multiple manufacturers, is not conducive to the smooth progress of weaving and dyeing. [0003] During the design process, the components of printing paste mainly include thickeners and additives. Among them, sodium alginate and cmc are the most commonly used thickeners, which are the key factors affecting the weaving and dyeing effect; in terms of formula compositio...
