Problems solved by technology

[0003] Although sodium alginate has many advantages, there are also disadvantages, such as easy to deteriorate in summer, serious viscosity drop, not suitable for fine printing, etc.
[0006] It is difficult to depaste, and depaste is not clean, so the hand feeling is always inferior to sodium alginate. The key reason why the composite printing paste with CMS or CMC as the main raw material cannot completely replace sodium alginate

Embodiment 1

[0066] Aliphatic amine polyoxyethylene ether 1815 is pre-processed into solid material through atomization drying equipment. Then mix 900g of CMS, 50g of sodium alginate, 10g of amylase NS, 15g of dipitan and 25g of atomized and dried 1815, and stir evenly to obtain a composite printing paste. Wherein, the degree of substitution of CMS is 1.0, the viscosity of 1% aqueous solution is 410 mPa.s; the molecular weight of diyout gum is 285 Daltons. The application properties of the composite printing paste are shown in Table 1.

Embodiment 2

[0068] Aliphatic amine polyoxyethylene ether 1810 is pre-processed into solid material through atomization drying equipment. Then mix 850g of CMC, 70g of sodium alginate, 30g of amylase NS, 10g of dipitan and 40g of atomized and dried 1810, and stir evenly to obtain a composite printing paste. Wherein, the degree of substitution of CMC is 1.5, the viscosity of 1% aqueous solution is 450 mPa.s; the molecular weight of Diyou gum is 400 Daltons. The application properties of the composite printing paste are shown in Table 1.

Embodiment 3

[0070] Aliphatic amine polyoxyethylene ether 1210 is pre-processed into solid material through atomization drying equipment. Then mix 650g of CMS, 300g of CMC, 24g of amylase NS, 6g of dipitan and 20g of atomized and dried 1210, and stir evenly to obtain the composite printing paste. Among them, the degree of substitution of CMS is 1.1, and the viscosity of 1% aqueous solution is 330 mPa.s; the degree of substitution of CMC is 1.8, and the viscosity of 1% aqueous solution is 350 mPa.s; the molecular weight of dipitan gum is 580 Daltons. The application properties of the composite printing paste are shown in Table 1.

Abstract

The invention discloses composite printing paste and a preparation method thereof. The composite printing paste comprises components in percentage by weight as follows: (a), 80%-97% of carboxyl C1-3 alkyl polysaccharide salt; (b), 0-10% of sodium alginate; (c), 0.5%-5% of biological enzyme; (d), 0.2%-2% of welan gum; and (e), 1%-5% of fatty amine polyoxyethylene ether, and the total weight of the composite printing paste is taken as benchmark. The composite printing paste is good in net permeability, good in stability, high in color yield and easy to remove, the hand feeling is soft, and the comprehensive performance of the composite printing paste is superior to sodium alginate.

Description

technical field [0001] The invention relates to a composite printing paste and a preparation method thereof, in particular to an environment-friendly high-performance reactive dye composite printing paste used in the textile industry and a preparation method thereof. Background technique [0002] Sodium alginate is commonly known as the crown of printing paste. Sodium alginate is widely used in cotton and rayon reactive dye printing. The raw material of sodium alginate is kelp. As a resource product, seaweed is currently widely used in food, cosmetics and other fields, and the application field is constantly expanding. Therefore, the price of sodium alginate is also rising, which brings great pressure to printing factories. to a huge cost burden. [0003] Although sodium alginate has many advantages, it also has disadvantages, such as easy to deteriorate in summer, serious viscosity drop, not suitable for fine printing and so on. Synthetic thickeners, sodium carboxymethyl...
