Description

A kind of extracting method of efficiently single bamboo fibre

Technical field

The present invention relates to the extractive technique of bamboo fibre, the extracting method of more particularly to single bamboo fibre, belong to agricultural machining skill Art field.

Background technology

Single bamboo alias：Thin lingnania chugii, water drum bamboo, small single bamboo, powder wax list bamboo, there is growth bamboo alias：Thin lingnania chugii, water drum Bamboo, small single bamboo, powder wax list bamboo, have growth fast, grow into forest it is fast, cut down the features such as phase is short, adaptive is strong, breeding is easy.Hurry up, grow into forest it is fast, cut down The features such as phase is short, adaptive is strong, breeding is easy.

SOUTHERN CHINA is produced, distribution Guangdong and Guangxi Provinces, Hunan, Fujian are the excellent bamboos that Guangdong and Guangxi Provinces and Hunan, Fujian some areas are cultivated extensively Kind, have growth fast, grow into forest it is fast, cut down the features such as phase is short, adaptive is strong, breeding is easy.Its vertical distribution reaches height above sea level 500m, but with 300m Following gentle slope, level land, the foot of the hill and He Xi two sides growth be preferred, no matter grown just on acid soil or lime soil Often, 18.9~20.0 DEG C of its samming ", 999.1~2136mm of annual precipitation in distributed area year.

The high 3--7m of stalk, footpath about 5cm, tops are sagging very long, close by white powder, internode length 30--60cm during the children of stalk surface.Often It is most and near equal to save branch.Sheaths of bamboo shoots sheath is hard, green-yellow when fresh, and by white powder, the back side is all over the thin undercoat of raw light color；Sheaths of bamboo shoots falls behind on sheaths of bamboo shoots ring There is the suberin ring that a circle is wider；Sheaths of bamboo shoots ear is long and narrow；Sheaths of bamboo shoots leaf inverts, and ovum shape lanceolar, nearly base portion has seta.There is leaf per sprig 4-8 pieces, blade wire lanceolar, long 20cm, wide 2cm, quality is relatively thin, and the back side is hairless or sparsely grow microtriche.

Lingnania chugii woods is mostly the pure forest of artificial cultivation, and stalk is upright, and just taper is bent, high 8~12m, 4~7cm of diameter, forest form Neatly, structure is single, and underground is rare, common are tomonea, Huashan alum, griffith streptocaulon root or leaf etc..

Lingnania chugii forest products amount is higher, and general per hectare often produces 10~12t of bamboo wood, 30~75t of fast-growing andhigh-yeilding trees per year.Stalk wall is relatively thin, Section is flat and dredges, and internode length is slightd with one of bamboo kind, is also first-class paper making raw material up to 100cm.

Bamboo fibre is exactly a kind of cellulose fibre extracted from the bamboo grown naturally, be after cotton, fiber crops, hair, silk it The fifth-largest natural fiber afterwards.The Component units of bamboo fibre products, can be individual fibers cell or fibre bundle.Bamboo fibre has The characteristics such as good gas permeability, instant water absorption, stronger wearability and good dyeability, at the same again have natural antibacterial, Antibacterial, except mite, deodorization and anti-ultraviolet function.Expert points out that bamboo fibre is a kind of natural environmental-protective type green truly Fiber.Bamboo fibre fabric is and popular with consumers again because it replicates the inherent characteristic of bamboo fibre completely, product consumption by Year rises.Green low-carbon, increasingly turn into the fashion of life.

Cellulose is the main matter for forming bamboo fiber cell, and it can be as the meaning of textile fabric.By In the difference in bamboo age, its content of cellulose is also different, as the tender bamboo of mao bamboon be 75%, life in 1 year be 66%, life in 3 years be 58%.Bamboo fibril Hemicellulose level in dimension is generally 14%~25%, and mao bamboon average content is about 22.7%, and with the increase in bamboo age, its Content has also declined, such as 2 years growth bamboos 24.9%, life 23.6% in 4 years.

Bamboo fiber products have natural antibacterial, antibacterial, sterilization effect, because having a kind of unique thing inside bamboo Matter, the material are named as " bamboo a kind of jade ", have naturally antibacterial, anti-mite, deodorization, insect prevention function.Observe under the microscope, bacterium In the fibres such as cotton, wood can amount reproduction, and the bacterium on bamboo fiber products can not only survive for a long time, and short It can also disappear or reduce in time, bacterial death rate is up to more than 75% in 24 hours.The new discovery of Japanese authoritative institution adds this One value-added content of product, by Chinese Cotton Piece Goods product quality supervision and inspection center and Chinese Academy of Sciences's Shanghai microbe research Detection also demonstrate that result above（It is thousands of times of results multiplied of bacterium that cotton towel is easily smelly in summer）.And cotton Product does not possess antibacterial, bacteria resistance function in itself, why mouldy, spoiled, tacky, is exactly bacterium prolific knot on towel Fruit.And why bamboo fiber towel is not in this phenomenon, it is primarily due to its own and possesses antibacterial, bacteria resistance function, bacterium It can not breed, can not even survive in the above.So bamboo fiber towel it is also not mouldy in the environment of warm moist, It is not spoiled, not tacky.

The content of the invention

Being detected through relevant expert physics Institute proves, single bamboo anti-uv-ray is better than other bamboo kind classes, for 200 ~ 400nm ultraviolets, the penetrance of cotton is 25%, and for the penetrance of single bamboo fibre less than 0.6%, its anti-uv-ray is cotton 41.7 times.And injury of the ultraviolet of this wavelength to human body is maximum, this be other textiles it is incomparable.Single bamboo is at me State's south yield is very big, and single bamboo is the very big bamboo kind of amount containing bamboo fiber, develops the extraction process of single bamboo fibre and is produced The production of industry metaplasia has important business and health effect.

A kind of extracting method of efficiently single bamboo fibre solves problem and adopted the technical scheme that by following step progress： First, bamboo wood is gone into minor matters, taper, root, scrape off bamboo green grass or young crops, be sawn into must length thick bamboo tube, with receive mechanically hit bamboo machine or hand Thick bamboo tube is split into the bamboo chip that width 2CM controls by work, bamboo chip is immersed in special NaOH degumming softening agents, degumming softening agent Concentration is 30% ~ 40%, soak time 30 ~ 50 hours；2nd, the bamboo chip soaked is cleaned, flattens bamboo chip with machinery, then use Moulding draw-wire machine is parsed into crude fibre, then is rinsed with water, removes colloid；3rd, crude fibre is put into digester, adds water logging and do not have, It is heated to more than 100 DEG C 2 ~ 3 hours, by being sirred and separated fiber and lignin, colloid top grade bur, is rushed again with water after pulling out Wash, remove the impurity such as colloid and obtain bamboo fibre；4th, fiber is placed in soak by bamboo, adds appropriate organic additive immersion 1 Softened within ~ 2 hours, pull out and receive centrifugal drier with dehydration, slough moisture content；5th, bamboo fibre is combed into and arranged together Strip set, then dry to moisture content and be less than 10%, bamboo fibre finished product is dressed up in subpackage.

It is a kind of efficiently single bamboo fibre extracting method invention beneficial effect be：A kind of extraction side of efficiently single bamboo fibre Method utilizes the high microsteping of single bamboo, first single bamboo cut into section, in blocks, carries out immersion softening with NaOH solution, also use machine Tool carries out squeezing and mashed, and extracts crude fibre, and crude fibre is carried out into high temperature decocts separation colloid and fiber, further rinses and isolates Pure fiber, finally it is dried to single bamboo product.A kind of extracting method process of efficiently single bamboo fibre is clear and definite, simple to operate, it is not necessary to Pressurization, is suitable for rural remote areas and is produced in situ in, reduce the cost of transport, improve production efficiency.
