Embodiment 1

[0048] Methods of phosphate cafeterian starch preparation methods of this embodiment are as follows:

[0049] Called 500kg of cassava raw starch to emulsified ions, and then add 1000kg to remove ionic water. The obtained starch emulsion was pumped into the reactor, and the reactor dispersing machine's rotation was controlled at 50-80 rpm / min continuously, adding 15kg of sodium sulfate, adding a 32 % concentration of liquid alkali 30kg to adjust the pH8-11, and the temperature was increased to 50 ° C. Slowly add 5kg oxide propylene cross -linked reactions and continue to react for 1.5 hours. After the reaction is completed, the cross -linked starch milk is required, and the pH value of the 25kg hydrochloric acid solution is used to 6. It is said that 5Kg of hyperlolate polyoxyethylene ether is used to add the cross -linked starch lactifer solution for esterization before treatment. The temperature continues to keep at 50 ° C, so that the water is fully exposed to starch particles, ...

Embodiment 2

[0052] Called 500kg of cassava raw starch to emulsified ions, and then add 1000kg to remove ionic water. The obtained starch emulsion was pumped into the reactor, and the reactor dispersing machine's rotation was controlled at 50-80 rpm / min continuously, adding 15kg of sodium sulfate, adding a 32 % concentration of liquid alkali 30kg to adjust the pH8-11, and the temperature was increased to 50 ° C. Slowly add 8kg ethylene cross -linked reactions and continue to react for 1.5 hours. After the reaction is completed, the cross -linked starch milk is required, and the pH value of the 25kg hydrochloric acid solution is used to 6. It is said that 5Kg of hyperlolate polyoxyethylene ether is used to add the cross -linked starch lactifer solution for esterization before treatment. The temperature continues to keep at 50 ° C, so that the water is fully exposed to starch particles, and the ester pharmaceutical agent and starch are fully exposed to reactions. Add 15kg of sodium dihydrogen ph...

Embodiment 3

[0063] The preparation method of composite decentralized printed paste for polyester chiffon fabrics for this embodiment is as follows:

[0064] 1. Complex and mixing: 50 copies of the phosphate cafeteria starch material prepared by the Illegal Example 2; 30 copies of hydroxyl -petuga bean gum, 10 sodium -based pussy soil; 4 copies of hydroxyeylcellin; Huangyuan collagen 2 Severe; 1 citric acid; put the above powder raw materials into a mixed kettle and stir at low speed at room temperature. After stirring the above powder for 30 minutes, use the spraying equipment to spray the three parts of the water -based polyurethane deeper (thickened) into the powder system, continue to stir for 10 minutes, and add 0.1 BIT preservatives to continue stirring for 10 minutes until the stirring is completely mixed completely until the stirring is completely stirred completely Uniform.

[0065] 2. Dry drying: Enter the drying box of the mixed material through the pipeline transmission system. The...

Abstract

The invention discloses a phosphate ester tapioca starch and a preparation method thereof. The phosphate ester tapioca starch is prepared by adopting a three-step compound starch modification method of cross-linking, catalysis and compound esterification; the phosphate ester tapioca starch of the present invention is prepared The paste ratio, electrolyte resistance and rheology are far superior to traditional phosphate ester starch. The invention also discloses a composite dispersion printing paste for polyester silk chiffon fabric and a preparation method thereof. The composite dispersion printing paste comprises phosphate tapioca starch, hydroxypropyl guar gum, sodium bentonite, hydroxyethyl Cellulose, xanthan gum, waterborne polyurethane thickener, citric acid and preservatives. The performance of the composite dispersion printing paste of the invention exceeds that of sodium alginate in permeability, rheology, level dyeing and the like, solves the technical problem that has always plagued the selection of printing paste for light and thin fabrics in the printing field, and greatly reduces the application cost.

Description

Technical field [0001] The invention involves the printing field of polyester chiffon fabrics. It specially involves a composite decentralized printed paste and their preparation methods for polyester chiffon fabrics for polyester chiffon fabrics. Background technique [0002] Polyester silk chipped fabric texture is light and transparent, soft and flexible, light and elegant appearance, good breathability and hanging, wearing elegant, comfortable, with the effect of simulation silk, the price is far lower than the real silk, and compared to compared Yu Zhensi is more likely to take care of maintenance everyday, and is favored by contemporary women. [0003] Printing paste is an important part of the printed color pulp, which can be scattered in water into a colloid solution with a certain concentration and viscous thickness. When printing, the paste is passed on the fabric as a carrier, which requires the paste to have good permeability and uniformity, but does not produce the p...
