The invention relates to a preparation method of an antibacterial and persistent air-jet vortex spinning core-spun yarn. The method includes: preparing viscose cotton rolls from viscose short fibers according to the process of opening and cleaning, and after the carding process, spraying nanofibers containing antibacterial agents onto a cotton web conveying device added after carding and before bundling into sliver, It is bundled through the bell mouth and drawn through the second stage to obtain the viscose sliver, which is then fed into the air-jet vortex spinning machine. The core-spun yarn prepared by the method has good antibacterial durability, and the vortex spinning core-spun yarn can combine the advantages of high strength and wear resistance of nylon core yarn, good evenness uniformity, high spinning efficiency, and good economical efficiency. value. |
