The process can lead a whole bamboo to be extended by a special tool and subsequently and directly processed without being cut; furthermore, the processed bamboo fiber is longer, finer and more uniform, the utilization ratio of the resource is high, the cost is low and the quality of the product is stable.
Description
[technical field]
The present invention relates to a kind of processing technology of bamboo, relate in particular to a kind of production technology of directly producing bamboo fiber with bamboo stem stalk (former bamboo).
[background technology]
Preparing bamboo fiber with methods such as machinery, physics, biochemistry is current heat subject and following novel industry development.
China has many patents of invention on the bamboo fiber manufacture method in recent years, CN11078520C has announced a kind of manufacture method, CN1261290C that former bamboo is opened bar, kicker, formation bamboo fiber bundle goods and has announced a kind of method that former bamboo bamboo chip is adopted pure physics, divide silk by boiling, desaccharification, degrease, after protein, starch are handled, through mechanical impact, tear, shredding becomes bamboo fibre.CN1185086C has announced by cold rolling, poach and has soaked, dewaters and comb operation such as system fiber etc., and the fiber of acquisition is mainly used in the production bamboo fiberboard.CN1217038 has announced a kind of bamboo wood and has become fine preparation method.This preparation method prepares, softens, washes, rolls, washes, urinates oxygen processing, washing, alkali lye kiering, washing, Urea bleaching, pickling, the step preface such as dewaters, shakes up, dries and can make bamboo fibre by sample.CN101210350 discloses a kind of organic processing technique for bamboo fibre.This organic processing technique for bamboo fibre:, block respectively by the selection classification; According to tabasheer, surf green with the bamboo wood burst; Carry out the branch silk respectively with surf green, the tabasheer of minute silk machine after to boiling; Through softening; Rinsing; Bleaching; Extracted bamboo fibre.
These above-mentioned production methods all do not break away from the technology that XianCheng's bamboo chip becomes bamboo fiber bundle again, and its process technology is more backward, and production efficiency is low, and the rapidoprint waste is serious, can't carry out streamline processing to realize efficient large-scale production to whole bamboo.And the integral body that present preparation method does not make full use of bamboo stem stalk (former bamboo) connects the fine characteristics of being convenient to out each other, be difficult to solve the bamboo fiber processing difficult problem that the bamboo taperingness is big, geomery varies and brought, cause the bamboo fibre produced of poor quality, fiber is thick, short, hard, indexs such as its uniformity, length, fineness, intensity can not reach weaving with and other industrial field to the instructions for use of bamboo fibre.
[summary of the invention]
The technical problem to be solved in the present invention, be to provide a kind of production technology of bamboo fibre, whole bamboo directly processed after flattening by special facility under the situation of hacking without cutting, and the bamboo fibre that processes is longer, thinner, more even, the resource utilization height, with low cost, constant product quality.
The present invention is achieved in that a kind of production technology of bamboo fibre, comprises the steps:
Step 100, select materials: each batch bamboo wood according to the place of production, bamboo classification in age, is deposited respectively;
