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
The present invention relates to field of textiles, relate in particular to a kind of production method of bamboo fibre.
Background technology
Bamboo fibre is a kind of cellulose fibre that from the bamboo of self-sow, extracts, and is the fifth-largest natural fabric after cotton, fiber crops, hair, silk.Bamboo fibre has good gas property, moment water imbibition, stronger ABRASION RESISTANCE and the good characteristics such as dyeability selected, have again simultaneously natural Hangzhoupro bacterium, antibacterial, remove end, deodorization and anti-ultraviolet function.The expert points out that bamboo fibre is a kind of natural environmental-protective type green fiber truly.
But up to now; Operations such as the production of bamboo fibre is adopted intercept, burst basically, goes green grass or young crops, removed Huang, boiling, pressure rolling well-thought-out plan tow have broken away from not the technology that XianCheng's bamboo chip becomes bamboo fiber bundle again, and its process technology is more backward; Production efficiency is low; The process equipment function singleness, the rapidoprint waste is serious, can't process to realize high-efficiency large-scale production whole bamboo or bamboo leftover pieces.And the critical process among the present preparation method is underused the design feature of bamboo wood; Its processing choose opportunities is improper, implements to open fibre at the best mechanics performance point of bamboo wood, and the bamboo fibre technology that becomes more meticulous is unreasonable; The bamboo fibre of being produced is of poor quality; Fiber is thick, short, hard, the requirement that indexs such as the fiber uniformity, length, fineness, intensity not only do not reach textile fiber, even can't satisfy the requirement for preparing composite, nonwoven material.
Summary of the invention
In order to overcome above defective, the technical problem that the present invention will solve is: propose that a kind of production efficiency is high, processing cost is low, the production method of the stay-in-grade bamboo fibre of bamboo fibre.
The technical scheme that the present invention adopted is: a kind of production method of bamboo fibre comprises the steps:
One, cuts off:, again bamboo wood is cut into the little bamboo chip of designated length with mechanical shock and compressor squeezing;
Two, soften: the bamboo wood that cuts is sent in the bating liquor that softens the pond softened;
Three, open fibre, classification, screening: bamboo wood is delivered to out fine seperator realize that fine separation is separated, opened to comb, air-flow is classified, obtain the bamboo filamentary fibers, utilize vibrating screen that the powder of bamboo filamentary fibers is removed again;
Four, kiering: adopt autoclave that above-mentioned little bamboo chip is carried out the softening processing of autoclaving, pressure is 5-6 atmospheric pressure, and temperature is between 155-175 ℃, and the processing time is 1-3 hour;
Five, clean, dewater: the bamboo filamentary fibers after will bleaching drains, and cleans to pH value 6-7 with the dilution heat of sulfuric acid that contains 0.1-0.2% then, cleans the back dehydration with clear water again;
Six, dewatered drying: the bamboo fibre after will washing dewaters with mechanical drying mode or vacuum mode or plate pressure mode, sends in the drier oven dry or under sunshine, dries naturally, and oven dry back bamboo fibre moisture is 5-25%;
Seven, enzyme is handled: with shower nozzle pectase evenly is sprayed onto on the bamboo filamentary fibers.
According to another preferred embodiment; A kind of production method of bamboo fibre comprises that further softening the processing is that bamboo wood is put into softening pond in the step 2, adds the solution that contains alkali or liquefied ammonia and soaks, and solution concentration is 1-5%; Liquid level exceeds bamboo wood 1-3 millimeter, and soak time is 10-15 hour.
According to another preferred embodiment, a kind of production method of bamboo fibre comprises that further it is one or more the mixture in the 2-8g/l hemicellulase that bating liquor in the said softening processing can be selected the pectase of concentration 1-10g/l, lignoenzyme that concentration is 1-20g/l, cellulase, concentration that concentration is 1-30g/l for use.
According to another preferred embodiment; A kind of production method of bamboo fibre further comprises and also comprises the detergent bleach operation between said step 4 and the step 5: bamboo fibre is put into sink after the clear water washing; Send in the Bellmer and under agitation bleach, wash with clear water once more with bleaching liquid.
According to another preferred embodiment; A kind of production method of bamboo fibre comprises that further said bleaching liquid selects calcium hypochlorite solution or liquor natrii hypochloritis, postassium hypochlorite solution for use; The concentration of bleaching liquid is 0.02-0.1%, and solution temperature is at 2-15 ℃, and bleaching time is 5-10 minute.
According to another preferred embodiment, a kind of production method of bamboo fibre comprises that further bamboo fibre of the present invention is a diameter at 0.09-0.15 millimeter, the length bamboo fibre at the 80-250 millimeter.
The invention has the beneficial effects as follows: bamboo is driven fine seperator and is given full play to bamboo wood the best after softening and open fine point, can adjust the machining parameter as required, obtains different fiber slenderness ratios; The bamboo fibre that makes processing than originally more carefully, more even; Its production process is reliable, and resource utilization is high, low processing cost; Environmental pollution is little, constant product quality.The fine bamboo fiber that the present invention produces has that long fineness is even, intensity is high, pliability is good; Fiber absorb-discharge humid, gas permeability are strong; Hangzhoupro bacterium deodoriging properties is especially outstanding; Be a kind of good and cheap, the natural function fiber of new generation that the ratio of performance to price is superior can be widely used in fields such as weaving, building materials, automobile.
