Abstract

The invention relates to spinning slurry manufacturing method. It includes the following steps: diluting spirit of salt; adding into starch solution; stirring in reaction kettle; heating to 50 deg.C; holding for three hours; adjusting pH value; adding the mixed liquor of sodium hydroxide and anhydrous sodium sulfate; dropping into chloroepoxy propane to react at 30 degree for 5hours; sampling to measure stability; stopping stirring to make the starch naturally subside; discharging the upper clear liquid; adding sodium carbonate to adjust pH value at 8-9; inducing acetic acid ethane; sealing the reaction kettle; adding sodium carbonate sometimes to keep pH value stable; reacting for 5 hours at 35-38 deg.C; using diluted hydrochloric acid solution to adjust pH value at 6-7; putting in sedimentation basin to sediment; cleaning; dehydrating; drying. The invention can replace polyvinyl alcohol, has the advantages of low cost, short operational path, high catalysis efficiency, low reacting temperature etc.

Description

technical field [0001] The invention relates to a production method of textile pulp. Background technique [0002] At present, due to the energy crisis and the shortage of chemical resources, the price of chemical products has risen, and the substitutes of chemical products have become the main subject of current research. Starch derived from natural plants is produced by photosynthesis and is inexhaustible. And can reduce CO in the atmosphere 2 , Protect the ecological balance and improve the living environment of the people. Nowadays, physical, chemical and enzymatic means can be used to promote its modification and replace chemical products through molecular cutting, rearrangement, oxidation or introduction of substituents in molecules to meet application requirements. [0003] Since the 1980s, the research and development of slurry has been greatly developed, and the products have developed from a few products to a dazzling number today. It has been widely used in te...
