Description
Technical field
The present invention relates to bamboo fiber processing technical fields, and in particular to a kind of efficiently high-quality processing method of bamboo fibre.
Background technology
Bamboo fibre system aftergrowth fiber is that China voluntarily researches and develops the successfully regenerated cellulose fibre using bamboo as raw material
Dimension manufactures process and all implements green production, belongs to the green fiber of environment-friendly type.The fiber differs markedly from cotton, fiber crops
The individual style of cellulose fibres is waited, strength is good, and wearability, hygroscopicity, drapability are all good, soft, wear cool and comfortable,
Dyeability is excellent, and gloss is beautiful, and with natural antibacterial functions.Due to bamboo fibre cross-sectional height " hollow ", and claimed
For " fiber that can be breathed ", have broad application prospects in textile industry.
The bamboo fibre of existing market is mainly made of 2 kinds of methods of chemical industry and physics, and wherein chemical method mainly uses
Spinning process after crushing, right this method destroy the original sterilizing function of bamboo, and product obtained does not have antibacterial functions；And object
For reason method mainly by rolled-on method, the fiber of preparation is thicker, and hardness is high, not soft enough.
The pectin and half fiber in natural fiber are removed such as the Chinese patent CN103774243 methods rubbed by cal rolling
The plain ingredient of dimension is volatilized with reducing its aldehydes during thermoforming, but during cal rolling is rubbed, often results in day
The major injury of right fiber so that its mechanical property substantially reduces.
If CN1587504A discloses a kind of processing technology of bamboo fibre, follow these steps：(1) pre-process：Mao bamboon is cut
It is disconnected, green peel is scraped off, is pulverized along machine direction；(2) in pretreatment pool, it is 5-10%'s to be configured to concentration by a certain percentage
Ca(OH)2Solution impregnates pretreated mao bamboon input pretreatment pool 10-30 days；Obtain preliminary bamboo fibre；It (3) will leaching
The preliminary bamboo fibre soaked, which is put into flushing tank, to be rinsed well, is scraped decontamination, is obtained pure bamboo fibre；It is characterized in that：
NaOH, (Na) being additionally added in pretreatment pool2CO3And NaHCO3Additive package.The advantage of the invention is that：Input
Less, it is at low cost, quick, using low-cost Ca (OH)2As process solutions, suitable additive is added in, can shorten and add
The work cycle improves the mechanical property of bamboo fibre.But the sterilization ability of bamboo is also with disappearance in soaking process.
The content of the invention
The technical problems to be solved by the invention are to provide that a kind of method is simple, and easily operated bamboo fibre is efficiently high-quality
Processing method.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of efficiently high-quality processing method of bamboo fibre, specific method step are as follows：
(1) the growth selection cycle in the new fresh and tender bamboo of 7-10 days as raw material, since tender bamboo growing way is fast, at one week or so
Fiber has been formed in growth course, but lignin is not yet formed or content of lignin is very low；
(2) surface irregularities of tender bamboo are cleaned out, is sent into press apparatus and carries out squeezing water removal, do not have in expressing process
Water removal process can be completed in water outflow；
(3) the tender bamboo after squeezing is put into softening agent and impregnated, made the tender bamboo after squeezing loose, lignin is removed
It goes；Soaking time is controlled when 5-24 is small, 30-55 DEG C of temperature；Since the content of lignin of tender bamboo is low, soaking time is than traditional
Method want it is short very much；
Above-mentioned softening agent is made of the component of following parts by weight：100 parts of solvent, 0.1 part of sodium formate, sodium acid carbonate
0.2 part, 0.5-1.5 parts of calcium activated, 0.2 part of nano silicone diatomaceous earth；
The solvent is pure water, deionized water or supercritical CO2；Use supercritical CO2Fluid, instead water as medium impregnates
It is discharged afterwards without waste liquid, realizes the zero-emission of sewage, eliminate the pollution of soda acid.
The pH of the softening agent is 6~7.5, temperature and pH be influence bamboo lignin be precipitated effect other two is important
Factor.Suitable temperature and pH value, can increase the effect that softening agent is combined with collagen, make the gelatin substances such as lignin quickly quilt
It absorbs；
(4) the tender bamboo after softening agent is impregnated, which is put into clear water, to be impregnated, bath raio 1:60, temperature room temperature, the time, 0.5-2 was small
When；The purpose impregnated with clear water is the substances such as remaining softening agent in the tender bamboo of dilution, makes fiber purer；
(5) tender bamboo is put into autoclave, temperature in the kettle control together with the clear water of immersion after the completion of clear water impregnates
System is at 90-185 DEG C, while the 5-10kg/cm that pressurizes2, kept for 80-120 minutes；Purpose is to make the abundant water swelling of bamboo, fiber
It splits；
(6) after the completion of pressurizeing, moment lays down the pressure of reaction kettle, and stops heating, and bamboo fibre is fine after instantaneous loss of pressure
Also instant exploding is tieed up, bamboo fibre semi-finished product are taken out, two pairs of rollers is sent into and rolls, the fiber not split is made to split when rolling；
(7) finished product bamboo fibre is obtained through drying, comb fibre.
Above-mentioned drying is carried out in vacuum cold wind drier, and 45-55 DEG C of drying temperature, cold air drying will not destroy fiber
Elasticity, antibiotic property.
The beneficial effects of the invention are as follows：The present invention changes tradition using ripe bamboo as raw material, uses tender bamboo as processing object,
Content of lignin is low, easily removes, and product quality is high, can keep the natural quality of bamboo fibre.
