Problems solved by technology

[0004] However, the production process of the above scheme is relatively complicated, the pH is difficult to control, and the viscosity and rheology are poor, resulting in low stability, poor mesh penetration, and unsatisfactory printing and dyeing effects.
Moreover, due to the use of organic matter as raw materials, it is easy to breed more bacteria, and long-term storage is easy to cause spoilage and deterioration

Embodiment 1

[0028] Composite printing paste, comprising the raw material composition of following parts by weight:

[0029] 60-90 parts of modified starch

[0030] 2 to 30 parts of vegetable gum powder

[0031] 0.1-0.6 parts of water-soluble preservatives.

[0032] Among them, the modified starch is phosphate starch. Vegetable gum powder is any one or more combination of xanthan gum powder, guar gum powder, Luowangzi gum powder, locust bean gum powder, tara gum powder, konjac gum powder, preferably guar gum powder Bean gum powder, Luowangzi rubber powder. The water-soluble preservative is Perazolam. The particle size of the modified starch is 15 mesh to 100 mesh, and the particle size of the vegetable rubber powder is 15 mesh to 100 mesh. This composite printing paste is yellow or light yellow powder (containing particles).

[0033] Phosphate starch is a water-soluble anionic starch product with a large degree of substitution and a large amount of negative charges on the starch macr...

Embodiment 2

[0036] 60-90 parts of modified starch

[0037] 2 to 30 parts of vegetable gum powder

[0038] 2-30 parts of sodium alginate

[0039] 0.1 to 0.6 parts of water-soluble preservatives, and the rest are similar to those in Example 1, and will not be repeated here.

[0040] Wherein, the modified starch is phosphate starch. Sodium alginate and starch phosphate are different types of fluids. Sodium alginate is a Newtonian fluid with good dilution resistance. Starch phosphate is a pseudoplastic fluid. The viscosity changes greatly when diluted, and it is difficult to control the viscosity required for application. , which brings certain troubles to the application. Vegetable glue powder is a kind of substance that can dissolve in water to form a colloidal and viscous substance, such as oats, barley, dried beans, psyllium, aiyuzi, etc., are rich in vegetable glue, which has a strong thickening effect and can Effectively enhance the permeability and improve the quality of printing and...

Embodiment 3

[0042] Raw material optimization weight parts is:

[0043] 60-90 parts of modified starch

[0044] 2 to 30 parts of vegetable gum powder

[0045] 2-30 parts of sodium alginate

[0046] 0.3-0.5 parts of water-soluble preservatives, and the rest are similar to those in Example 2, and will not be repeated here.

Abstract

The invention relates to a composite printing paste and application thereof. The composite printing paste is prepared from the following raw materials in parts by weight: 60-90 parts of modified starch, 2-30 parts of plant gum powder and 0.1-0.6 part of water solube preservative. The composite printing paste has the following application: taking 3-10 parts of composite printing paste and 90-97 parts of water in parts by weight, and uniformly mixing, wherein the optimized parts in part of the raw materials are 4-6 parts of composite printing paste and 94-96 parts of water. The composite printing paste has the advantages that the compounding is reasonable, stable property, the acidity or alkalinity is especially suitable for printing, the paste has good compatibility with other chemicals, and the cost is low; the anti-corrosion property is high, the paste is difficult to nourish bacteria and deteriorate and is suitable for storing for a long term, and the raw paste and printing ink have long preservation time and no toxicity; the anionic paste has good rheological property and ensures good printing property.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a composite printing paste and its application. Background technique [0002] Printing paste is a polymer compound that thickens printing pastes, and generally can be dissolved in water or fully swelled and dispersed in water to form a thick colloidal solution. As the main component of printing paste, it determines the running performance of printing, the amount of color given to the surface of the dye, the smoothness of the outline of the pattern, etc. Commonly used printing pastes include sodium alginate, dragon gum, gum arabic, etc., but they are more expensive. For example, sodium alginate is an ideal paste for reactive dye printing. Its biggest feature is that it does not react with the dye, and it is easy to transfer the dye from the paste to the fiber. At the same time, the printed pattern is clear, bright and high in color. Feel good. Not only suitable for ...
