Ketone solution is added inorganic base substance and adjusts pH value to 8~9, and heat preservation, which is placed in the microwave reactor of 200~240W, reacts 5
Then~10min is 6.5~7 with dilute hydrochloric acid neutralization reaction system to pH value, filtering is cleaned, 50~60 DEG C with ethanol water
Lower drying, then disperses gained modified starch in aqueous solution of sodium bisulfite, be heated to 37~42 DEG C of insulation reactions 5~
6h adjusts pH value to 6.5~7, filters, cleaning, drying at 40~50 DEG C；
S2: esterification starch obtained by S1 is configured to the esterification starch cream that mass fraction is 0.7~1%, is heated to 90~95 DEG C of heat preservations
1~2h is cooled to 50~70 DEG C of heat preservation 3h, wool yarn is impregnated in esterification starch cream, naturally dry after taking-up.
Preferred technical solution is that it is 30~40% that acidified starch, which accounts for the weight percent of starch milk, in S1, and sodium sulphate adds
Entering amount is 3~5%, and the weight percent of maleic anhydride is 25~33% in maleic anhydride acetone soln, aqueous solution of sodium bisulfite
The weight percent of middle solute is 2.4~5%, and the weight ratio of modified starch and aqueous solution of sodium bisulfite is (2~3): 6.
Preferred technical solution is that inorganic base substance is sodium hydroxide solution.
Preferred technical solution is that it is 30~40% that esterification starch, which accounts for the weight percent of esterification starch cream, in S2.
The advantages and beneficial effects of the present invention are:
The esterification starch uses maleic anhydride modified acidified starch to the sizing technique of wool yarn, prepares sulfo-succinic acid esterification
Starch hinders under cryogenic conditions in farinaceous size since in starch surface grafting sulfo-succinic acid substituent group, steric hindrance increases
The generation of gelatin phenomenon is fitted so that sulfo-succinic acid esterification farinaceous size at a temperature of telling somebody what one's real intentions are has good adhesion property
Starching for low temperature wool yarn is handled.
