Embodiment 1

[0108] Embodiment 1, the preparation of cold transfer printing paste

[0109] Recipe composition:

[0110] xanthan gum is 2%,

[0111] Sodium L-pyrrolidone carboxylate 1%,

[0112] Etherified starch is 28%,

[0113] Adjust to 100% with distilled water.

[0114] See also the preparation method figure 1 Flow chart of cold transfer printing paste synthesis process. Specifically, in distilled water, xanthan gum accounting for 2% of the total weight percentage of the cold transfer printing paste is placed in a stirrer, and stirred for 2 hours at a temperature of 70°C and 1400-2800r / min. Slowly add 1% L-pyrrolidone sodium carboxylate (PCA-Na) accounting for the total weight percentage of the cold transfer printing paste, and mix uniformly to form a colloidal prepaste for use. In distilled water, the low-viscosity etherified starch accounting for 28% of the total weight percentage of the cold transfer printing paste is placed in a reaction kettle, and the temperature is raise...

[0116] Recipe composition:

[0117] Xanthan gum is 0.5%,

[0118] Sodium L-pyrrolidone carboxylate 0.4%,

[0119] Etherified starch is 45%,

[0120] Adjust to 100% with distilled water.

[0121] See also the preparation method figure 1 Flow chart of cold transfer printing paste synthesis process. Specifically, in distilled water, xanthan gum accounting for 0.5% of the total weight percentage of the cold transfer printing paste is placed in a stirrer, and stirred for 2 hours at a temperature of 70°C and 1400-2800r / min. Slowly add 0.4% of sodium L-pyrrolidone carboxylate (PCA-Na) accounting for the total weight percentage of the cold transfer printing paste, and mix uniformly to form a colloidal prepaste for use. In distilled water, the low-viscosity etherified starch, which accounts for 45% of the total weight percentage of the cold transfer printing paste, is placed in a reaction kettle, and the tem...

Embodiment 3

[0122] Embodiment 3, the preparation of cold transfer printing paste

[0123] Recipe composition:

[0124] 3.5% guar gum,

[0125] Sodium L-pyrrolidone carboxylate 3%,

[0126] Etherified starch is 20%,

[0127] Adjust to 100% with distilled water.

[0128] See also the preparation method figure 1 Flow chart of cold transfer printing paste synthesis process. Specifically, in distilled water, the guar gum that accounts for 3.5% of the total weight percentage of the cold transfer printing paste is placed in a stirrer, and stirred for 2 hours at a temperature of 70 ° C and 1400 to 2800 r / min. Slowly add 3% L-pyrrolidone sodium carboxylate (PCA-Na) accounting for the total weight percentage of the cold transfer printing paste, mix evenly, and form a colloidal prepaste for use. In distilled water, the low-viscosity etherified starch accounting for 20% of the total weight percentage of the cold transfer printing paste is placed in a reaction kettle, and the temperature is ra...

Abstract

The invention relates to cold-transfer printing thickener, printing paste thereof and a preparation method thereof, in particularly to cold-transfer printing paste comprising the following components: polysaccharide macromolecular compounds, L-PCA-Sodium (L-pyrrolidone carboxylic acid-sodium), etherified starch and water. The invention further relates to printing paste comprising the following components: reactive dye, defoaming agent, leveling agent, pH value stabilizer, water and printing thickener, which is selected from any one of the printing thickeners in the claims 1 to 6. Moreover, the invention further relates to the printing thickener and a method for preparing the printing paste. The cold-transfer printing thickener and the printing paste prepared from the cold-transfer printing thickener in the invention are suitable for the production process of cold-transfer printing; and owing to the stable physical properties, the printing thickener leads to no reduction in viscosity when in use.

Description

technical field [0001] The invention relates to the printing and dyeing industry in the textile industry, in particular to a printing paste containing polysaccharide polymers, sodium L-pyrrolidone carboxylate and etherified starch, a printing paste containing the printing paste, and the Describe the preparation method of printing paste and printing paste. Background technique [0002] The paste in the textile printing industry, often referred to as the original paste, is an important raw material in the textile printing industry. The paste is a liquid dispersion medium, a carrier of dyes and fillers, and must have a certain viscosity. The printing effect of paste printing is closely related to the printed fabric, printing method and printing paste composed of paste and dye. The rheology, shear force, viscosity, viscosity, and drying speed of the printing paste mainly depend on the performance of the original paste, that is, the paste, so the paste plays a vital role in the ...
