The invention relates to an acetate
starch formulation for
textile sizing material, and a preparation method thereof. The acetate
starch formulation comprises
corn starch, caustic soda, oxidizer,
reducer, and esterifying
reagent, and is characterized in that the acetate
starch formulation also comprises
alcohol. The preparation method comprises the following steps: adding the
corn starch, caustic soda and
alcohol into a feed box, and stirring; sprinkling liquid oxidizer, sprinkling powdery
reducer in dispersed manner, spraying with liquid esterifying
reagent, heating with steam, evacuating, heating with steam to 65 DEG C, and persistently evacuating until the
alcohol in the feed box is completely volatilized, distilled and recovered; and discharging, sieving, pulverizing and mixing. The alcohol
solvent phase is employed to prepare acetate starch to reduce the production cost. The acetate starch replaces PVA in
textile pulp application to acquire good effect, higher substitution degree, and excellent size film performance, and improve the
sizing quality and level of subsequent
textile sizing. The alcohol
solvent phase production does not require water resource to have no waste
water treatment.
