Technical scheme of the present invention is:
A kind of bamboo fibre process follows these steps to: (1) preliminary treatment: mao bamboon is broken apart by chopping, scraped off rascal, pulverize along machine direction; (2) in pretreatment pool, be mixed with the Ca that concentration is 5-10% (OH) by a certain percentage
2Solution drops into pretreatment pool with pretreated mao bamboon, soaks 10-30 days in solution; Remove non-fibre composition in the mao bamboon, obtain preliminary bamboo fibre; (3) soaked preliminary bamboo fibre is put into flushing tank and rinse well, scrape decontamination, obtain pure bamboo fibre; It is characterized in that: in pretreatment pool, also add the NaOH of 0.01-0.05%, the Na of 0.01-0.05%
2CO
3And the NaHCO of 0.001-0.03%
3Additive package.
At Ca (OH)
2Under the effect of solution and additive package, soak after 10-30 days, the skeleton of bamboo fibre is not dissolved by alkaline matter, obtains keeping; And non-fibre composition such as protein is soft by the alkaline matter bull pine, easily is dissolved in the solution, is easy to be rinsed come off separate with the skeleton of bamboo fibre.
A kind of bamboo fibre process obtains pure bamboo fibre and also carries out post processing, and post processing is adopted the low temperature air dry or handled at the drying chamber low temperature drying.
A kind of bamboo fibre process also adds 0.03% NaOH, 0.02% Na in pretreatment pool
2CO
3And 0.015% NaHCO
3Additive package.
The invention has the advantages that: less investment, low, the instant effect of cost are applicable to vast rural area, the particularly mountain area demand to the comprehensive utilization of mao bamboon.Adopt Ca (OH) with low cost
2As process solutions, add an amount of additive, can shorten the process-cycle, improve the mechanical property of bamboo fibre.

Embodiment 4,
A kind of bamboo fibre process is characterized in that: obtain pure bamboo fibre and also carry out post processing, post processing is adopted the low temperature air dry or is handled at the drying chamber low temperature drying.All the other are with embodiment 3.
Embodiment 5,
The contrast experiment:
A kind of bamboo fibre process, get the raw materials ready: cut down in the mao bamboon with 2-4 in growth period, decaptitating truncates, and is cut into certain length, scrapes off rascal, pulverizes along machine direction.Produce bamboo fibre:
(1) in pretreatment pool, is mixed with calcium hydroxide [Ca (OH) by a certain percentage
