Embodiment 1

[0059] Embodiment 1: A kind of guar gum silk printing paste and preparation method thereof

[0060] see figure 1 As shown, add 550g methanol and 250g guar gum in a 1000ml three-necked flask, stir for 10min and add 52g of 30% liquid caustic soda (sodium hydroxide), 10g of 80% triethanolamine, 10g of 5% acetone, 12g of 37.5% formaldehyde and 27.5% H 2 o 2 54g, the temperature was raised to 50°C for 2h, and the reaction was carried out. Then, add 30% liquid caustic soda 52g, in reaction vessel, pass nitrogen 5 minutes, rush into oxirane (gas) under nitrogen protection state, control speed (about 30g), the time is 2 hours. Then, cool to 40°C, neutralize to pH=6.5 with hydrochloric acid, and filter. The filter cake was washed with methanol for 50 min and filtered. Dry the filter cake, grind it finely, pass through a 200-mesh sieve, and blend the preservative (phenol or paraben) and complexing agent (sodium hexametaphosphate) to obtain 290 g of the finished product.

Embodiment 2

[0061] Embodiment 2: a kind of guar gum silk printing paste and preparation method thereof

[0062] see figure 1 As shown, add 550g methanol and 250g guar gum in a 1000ml three-necked flask, stir for 10min and add 40g of 30% liquid caustic soda (sodium hydroxide), 10g of 80% triethanolamine, 10g of 5% acetone, 12g of 37.5% formaldehyde and 27.5% H 2 o 2 52g, the temperature was raised to 48°C for 2h, and the reaction was carried out. Then, add 50g of 30% liquid caustic soda, feed nitrogen into the reaction vessel for 5 minutes, rush into ethylene oxide under nitrogen protection state, control the speed (about 40g), and the time is 2 hours. Then, cool to 40°C, neutralize with hydrochloric acid to pH=6.5, and filter. Wash the filter cake with methanol for 50 minutes and filter, dry the filter cake, grind it finely, pass it through a 200-mesh sieve, and mix the preservative (phenol or paraben) and complexing agent (sodium hexametaphosphate) to obtain 300 g of the finished prod...

Embodiment 3

[0063] Embodiment 3: a kind of guar gum silk printing paste and preparation method thereof

[0064] see figure 1 As shown, add 550g methanol and 250g guar gum to a 1000ml three-necked flask, stir for 10min and add 58g of 30% liquid caustic soda, 10g of 80% triethanolamine, 10g of 5% acetone, 12g of 37.5% formaldehyde and 27.5% H 2 o 2 56g, the temperature was raised to 52°C for 2h, and the reaction was carried out. Then, add 54g of 30% liquid caustic soda, feed nitrogen into the reaction vessel for 5 minutes, pour ethylene oxide under nitrogen protection state, control the speed (about 60g), and carry out the etherification reaction for 2 hours. Then, cool to 40°C, neutralize with hydrochloric acid to pH=6.5, and filter. Wash the filter cake with methanol for 50 minutes and filter, dry the filter cake, grind it finely, pass it through a 200-mesh sieve, and blend preservative (phenol or paraben) and complexing agent (sodium hexametaphosphate) to obtain 310 g of finished prod...

Abstract

The invention relates to a guar gum real silk printing paste slurry and relative preparation, which uses guar gum as main material and mellow as solvent, and in alkali condition, uses hydrogen dioxide solution as oxidant, to realize oxidation and decompositon; at the same time, uses multi hydroxylamine compound and aldehyde ketone compound as cross liner to process coupling reaction with guar gum; at last, adds sodium-hydroxide and uses ethylene oxide to process etherification to attain final product. The invention mainly supports the printing of real silk, and the printing of other dyes except from active dye. The inventive product has the advantages of easy preparation, better flow-ability, better match property to other dye agent, while treated real silk will have clear figure, fresh color, better uniformity, and better penetrability, without viscosity and network jam.

Description

technical field [0001] The invention relates to a textile printing and dyeing auxiliary agent and a preparation method thereof, in particular to a guar gum silk printing paste and a preparation method thereof. The printing paste of the present invention is mainly aimed at the printing of real silk, and can also be used for fabric printing of other dyes except reactive dyes. Background technique [0002] Printing paste is a thickening substance in textile printing color paste. It is one of the main components of printing color paste and plays an important role in the quality of printing products. [0003] Domestic silk printing pastes used to be mainly wheat starch, starch derivatives, natural dragon gum, etherified pod gum, clay, carboxymethyl cellulose, emulsified paste, etc. Although these pastes have the characteristics of low price and bright colors, they take a long time to make and cook paste, consume a lot of energy, are not easy to desizing, and are prone to defects...
