Embodiment 1

[0022] The bacterial cellulose wet film is held and fed by a holding roller with a diameter of 25 mm. Under the action of a licker-in roller with a diameter of 300 mm, a rotating speed of 400 rpm, a length of 10 mm, and a density of 10 needles / cm2, the bacterial cellulose wet film is The bacterial cellulose wet film was carded and segmented to obtain ultrafine bacterial cellulose fibers with a fiber diameter of 450 nm and a length of 5-100 mm. In order to facilitate the requirements of the next process, the fibers on the licker-in roller are peeled off by the fiber stripping device of the air nozzle, and the fibers are pressed into strips by the fiber pressing device, and the bacterial cellulose fiber strips after the strips are directly introduced into the diameter of 400mm. inside the coiler. When the coil barrel is full, the coil barrel is directly sent to the spinning process, and the nano bacterial cellulose superfine fiber yarn is spun by the traditional ring spinning pr...

Abstract

A processing method of nano-bacterial cellulose superfine fiber yarn provides a scientific basis for the in-depth study of bacterial cellulose cellulose materials; the bacterial cellulose wet film is used as the base material, and the bacteria are punctured, cut and combed at high speed The cellulose wet film is turned into bacterial cellulose fiber; the obtained bacterial cellulose fiber is formed into slivers by a carding machine, and after the sliver is formed, it is processed and spun into nano-bacterial cellulose superfine fiber yarn by spinning technology. The present invention provides feasibility for the further deep processing of bacterial cellulose cellulose materials; lays a foundation for realizing large-scale industrial production of bacterial cellulose cellulose materials; theoretical and practical guarantees. The bacterial cellulose yarn processing method provided by the invention has clean production environment, no toxicity, simple and economical production method, high production and processing efficiency, wide application fields of the produced bacterial cellulose yarn, environmental protection, low cost and high economic efficiency.

Description

technical field [0001] This patent relates to a method for processing nano-bacteria cellulose superfine fiber yarn. Background technique [0002] Cellulose in nature includes plant cellulose, seaweed cellulose and bacterial cellulose (BacterialCellulose, BC). Bacterial cellulose is a general term for cellulose biosynthesized by microorganisms. Bacterial cellulose is polymerized from pure D-glucose with extremely high purity and is not mixed with other polysaccharides. As a novel material, bacterial cellulose has many unique properties and has attractive commercial potential. 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, ...
