Phosphate ester cross-linked starch and producing method thereof

Abstract

The invention discloses phosphate ester crosslinked starch and a production method thereof. The production method is as follows: wheat flour, a crosslinking agent, a penetrant, an esterifying agent, a dispersant, a stabilizer, a smoothing agent, an accelerant, an antistatic agent, an antifoaming agent, an antiseptical agent and slurry are weighed and directly and uniformly stirred in a kneader according to certain quantity, and a mixture obtained is weighed and packaged. As for selection of various raw materials, more than one raw material can be selected, and the composition effect of three to five raw materials is optimum. The content of the starch is correspondingly adjusted according to the ash and the biceps of the raw materials and various raw starch varieties such as wheat in different areas; the grade requirement of the slurry can be optimally adjusted according to the customer requirements; parameters of ten agent varieties are subjected to corresponding mechanical adjustment according to difference of finished products of the raw materials, etc., and lowest cost and optimum quality in any grade are realized; and the customer requirements on different varieties of sized yarns and slurry can be met by increase or reduction of the agent varieties.

Description

technical field [0001] The invention relates to a phospholipid crosslinked starch and a production method thereof. Background technique [0002] Starch is a natural polymer compound with abundant resources, inexhaustible supply and good adhesion. It is commonly used in the textile industry as a treatment agent and sizing agent for yarn and fabric. The sizing process can Make the fibers stick to each other, increase the breaking strength and grinding ability of the yarn, can withstand various mechanical forces in weaving, and reduce fluffing and broken ends, but the original starch paste has high viscosity and poor fluidity, and there is "regression". Therefore, its application is greatly limited, and the quality of the starch used is not stable enough, the batch difference is large, and the quality of sizing is not good or bad. [0003] In the traditional modified starch production process, strong alkali swelling, strong acid neutralization, and water washing are used, whic...

[0002] Starch is a natural polymer compound with abundant resources, inexhaustible supply and good adhesion. It is commonly used in the textile industry as a treatment agent and sizing agent for yarn and fabric. The sizing process can Make the fibers stick to each other, increase the breaking strength and grinding ability of the yarn, can withstand various mechanical forces in weaving, and reduce fluffing and broken ends, but the original starch paste has high viscosity and poor fluidity, and there is "regression". Therefore, its application is greatly limited, and the quality of the starch used is not stable enough, the batch difference is large, and the quality of sizing is not good or bad.

[0003] In the traditional modified starch production process, strong alkali swelling, strong acid neutralization, and water washing are used, which not only consume a large amount of raw materials, but also reduce the quality of the product. The production of traditional phosphate starch requires high investment in fixed assets and high labor intensity.
