The preparation method comprises the following steps: step 1, corn fiber and oil are mixed to obtain treated fiber; wherein the weight percentage of the corn fiber and the oil is (100-99):(0-1); step 2, the treated fiber is subjected to a scutching process to obtain a fiber carded sliver; step 3, the fiber carded sliver is subjected to a drawing process to obtain a fiber drawn sliver; and step 4, the fiber drawn sliver is spun by using a vortex spinning process to obtain the corn fiber vortex spinning yarn. The application is used for yarn spinning.

This utility model discloses an automatic separation and collection device for heavy debris in an airflow conveying system, relating to the technical field of airflow separation equipment. The separation body includes a cylindrical cavity with a conical guide hood at the top. A spiral feed plate is located between the outer side of the guide hood and the inner wall of the cavity. A feed pipe is located on one side of the upper part of the cavity, a discharge pipe is located at the top of the cavity, and a discharge port is located at the bottom of the cavity. Corn fibers, being lightweight and highly susceptible to airflow, move upwards more easily with the airflow, while heavy debris, due to gravity and centrifugal force, tends to sink closer to the inner wall of the cavity, significantly improving the initial separation efficiency and reducing the mutual entanglement of corn fibers and heavy debris.

This invention discloses a method for preparing highly dispersible corn cellulose nanocrystals, belonging to the technical field of cellulose nanocrystals. The method includes the following steps: organic acid pre-swelling and activation, dilute sulfuric acid hydrolysis, high-pressure microfluidic homogenization, dialysis, and concentration. The dilute sulfuric acid hydrolysis method involves adding ferric chloride and xylitol to a dilute sulfuric acid solution, stirring to dissolve, preheating to 70-85℃ and maintaining the temperature, adding activated cellulose filter cake, stirring thoroughly to disperse it evenly, reacting at a constant temperature of 70-85℃ for 10-15 minutes, and then adding 4-5 times the volume of deionized water to terminate the hydrolysis, obtaining a hydrolyzed suspension. This invention significantly shortens the hydrolysis time, ensures the product's white color and high crystallinity, improves the product's thermal stability, dispersion stability, and redispersibility, meeting the needs of high-end applications.
