Fiber sterilization device and method

Abstract

A fiber sterilization device is used to sterilize a fiber group formed by multiple fibers. It comprises a tube, a gas supply device, a fiber supply device, and a sterilization device. The tube has a gas flow channel inside, with a front end and a rear end. The inner diameter of the gas flow channel at the rear end is larger than that at the front end. The front end of the flow channel is connected to the gas supply device. The fiber supply device provides multiple fibers through a feeding channel into the gas flow channel, and utilizes the Venturi effect to draw the multiple fibers from the feeding channel into the gas flow channel. The sterilization device sterilizes the multiple fibers entering the gas flow channel using a sterilization mechanism, and the feeding channel is closer to the front end of the flow channel than the sterilization device. This invention also provides a fiber sterilization method.
