Production method for bamboo fiber

Abstract

The invention relates to a production method for bamboo fiber, which comprises steps of cutting, softening, fiber splitting, scouring, bleaching, cleaning, dewatering, drying, enzyme treatment and the like. An optimal fiber splitting point after bamboo is softened can be fully developed by a fiber splitting separator, machining parameters can be adjusted according to requirement, and different slenderness rates of the fiber are obtained to make the processed bamboo fiber finer and more uniform than original fiber. The production process is reliable, the resource utilization rate is high, the processing cost is low, environmental pollution is low, and the product quality is stable. The fine bamboo pure fiber produced by the invention has the characteristics of uniform length and fineness, high intensity, good flexibility, high moisture absorbing and releasing performance, high air permeability and particularly remarkable bacteria resistance and deodorization, is a new generation natural functional fiber which is cheap and has high quality and superior cost performance, and can be widely applied to fields of textile, building, automobiles and the like.

Description

technical field [0001] The invention relates to the textile field, in particular to a production method of bamboo fiber. Background technique [0002] Bamboo fiber is a kind of cellulose fiber extracted from naturally growing bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has the characteristics of good air selection, instant water absorption, strong wear resistance and good dyeability, and at the same time has natural bacteria-killing, antibacterial, end-removing, deodorizing and anti-ultraviolet functions. Experts pointed out that bamboo fiber is a real natural environment-friendly green fiber. [0003] But so far, the production of bamboo fiber basically adopts operations such as sectioning, splitting, degreening, deyellowing, steaming, pressing and rolling into bamboo strands, which cannot be separated from the process of first forming bamboo slices and then forming bamboo fiber bundles.

Problems solved by technology

[0003] But so far, the production of bamboo fiber basically adopts operations such as sectioning, splitting, degreening, deyellowing, steaming, pressing and rolling into bamboo strands, which cannot be separated from the process of first forming bamboo slices and then forming bamboo fiber bundles. The technology is relatively backward, the production efficiency is low, the processing equipment has a single function, and the waste of processing materials is serious. It is impossible to process the whole bamboo or bamboo scraps to achieve efficient large-scale production

And the key procedure in the present preparation method does not make full use of the structural characteristics of bamboo, its processing timing is improperly selected, the fiber opening is not implemented at the best mechanical performance point of bamboo, the bamboo fiber refinement process is not reasonable, and the bamboo fiber produced is of poor quality , the fiber is thick, short, hard, fiber uniformity, length, fineness, strength and other indicators not only fail to meet the requirements of textile fibers, but even fail to meet the requirements of preparing composite materials and non-woven materials
