preparation example Construction

[0017] The preparation method of compound paste of the present invention, specifically implement according to the following steps:

[0018] Step 1: Weigh the modified starch, dragon gum, guar gum, Arabic gum and water according to the mass ratio of 5-7:1-3:1:1:1-2, mix, heat to 25-35°C, and stir Evenly, continue to stir into a thick paste, set aside to make a compound paste.

Embodiment

[0020] The composite paste prepared when the modified starch content is 50%-70% is made into a composite paste with a solid content of 3%, 5%, and 7%. The paste-forming rate curve is as follows: figure 1 shown.

[0021] figure 1 It shows that after compounding the compound original paste, when the modified starch paste content is 60%, the viscosity has reached 10,000 when the solid content is 3%. With the increase of solid content, the viscosity gradually increases, showing a linear relationship. It shows that under the same viscosity, the composite raw paste compounded under different proportions has the lowest solid content when the content of modified starch is 60%, which can be explained that printing with this raw paste can save production costs.

[0022] When the modified starch content is 60%, the dragon gum paste is 10%-30%, the guar gum paste is 10%-20%, and the arabic gum paste is 10%-20%, the compound raw material with the same viscosity can be made. Paste, its pr...

Abstract

The invention discloses a composite paste material, comprising the following components by mass percentage: 50-70% of modified starch, 10-30% of gum tragacanth, 10-20% of guar gum, and 10-20% of gum Arabic. The preparation method of the composite paste material comprises the steps of: weighting all components and water in proportioning, mixing the components and water, heating the mixture to be 25-35 DEG C, stirring uniformly and stirring continuously to form viscous paste to prepare the composite paste material. The composite past material solves the problems that the apparent color yield is low, the printing edge sharpness is low, the permeability of starch paste, the printing evenness and the washability are poor due to adoption of sodium alga acid in the existing printing paste material.

Description

technical field [0001] The invention belongs to the technical field of textiles, relates to a paste for printing, in particular to a compound paste, and also relates to a preparation method of the compound paste. Background technique [0002] As the main paste for reactive dye natural fiber printing, sodium alginate has the advantages of strong paste-forming ability and no reaction with reactive dyes, and is widely used. However, due to its high price, the apparent color yield and printing outline definition Starch paste, which is also used as a printing paste, has lower permeability, printing uniformity, and ease of washing than sodium alginate paste. It is imminent to study a kind of printing paste that takes into account the excellent properties of both and the printing paste with low price. Researchers at home and abroad have done a lot of work on the study of printing pastes. People such as R.Schneider have done the experiment that adds biodegradable additive when gua...
