Abstract

A nanometer bacterial cellulose ultrafine fiber processing device comprises a pair of rollers (2) which are used for holding a bacterial cellulose wet film, wherein a licker-in roller (3) is arranged behind the rollers (2), a fiber separation device (4) is arranged on one side of the licker-in roller, and a strip circling device (5) is arranged behind the fiber separation device. By means of the processing device for physical refining of bacterial celluloses, the bacterial cellulose wet film is processed to be in an ultra thin and ultra long fiber state, and then processed through the spinning technology to manufacture nanometer bacterial cellulose ultrafine fiber yarn in a spinning mode. When the nanometer bacterial cellulose ultrafine fiber processing device is used for processing, the production process is non-toxic, the processing device is clean, simple, economical and high in efficiency, and fibers obtained through the processing device are wide in application field.

Description

technical field [0001] The invention belongs to textile equipment, and in particular relates to a processing equipment for physical refinement of nano-bacteria cellulose superfine fibers. Background technique [0002] The molecular structure of bacterial cellulose (BC) is basically the same as that of plant cellulose, but its important structural features and properties make its practical application significance far greater than that of plant cellulose. It not only has good mechanical properties, air permeability, bioaffinity, biocompatibility, biocompatibility and good biodegradability, but also has high purity, high degree of polymerization, high crystallinity, high water content The physical and chemical properties such as high mechanical stability and high mechanical stability are superior to plant cellulose, and these properties are all caused by the specific network nano-supramolecular structure formed in the aqueous medium. Therefore, it is recognized as a new type ...
