The method of method, the bamboo fiber blended yarn.
Background technology
Cellulose is a kind of polysaccharide that widely distributed, yield is most in nature, be it is most abundant natural on the earth, it is renewable
Macromolecule.Cellulose be earliest become textile fabric chemical fibre, using nature can be constantly regenerating natural fiber as raw material
And be made, cellulose fibre is with a long history in staple fibre, widely used, and fiber has nontoxic, strong absorptive, can give birth in itself
The advantages that thing is degraded, meets renewable, biodegradable and environment-friendly materials requirements.
Therefore, the use of cellulose matrix fibrous material and the exploitation of cellulose derivative fiber cause domestic and international crowd
The concern of more researchers.The flammable and inflammability of natural macromolecular material greatly constrains their application, and by interior decoration
Fire caused by product and textile occurs again and again.It is fire-retardant to prevent and reduce the Strategic Measure of fire when preventing the exploitation of material from using
One of, wherein addition fire retardant is the conventional method of flame-retarded technology, for halogen, nitrogen, phosphorus type flame retardant, during use
Toxic gas can be produced, secondary injury is caused to human body, in process of production, there is also environmental pollution after meeting fire burning and discarding
The problem of.Therefore Green Flammability technology is the trend of the flame-retardant modified development of material.Studies have found that just there is this with alginate fibre
Matter flame-retarding characteristic, and metal ion plays flame retardant effect in its mechanism.
The mechanical property of natural bamboo fibre is very superior, it draws high intensity ratio other natural materials (except numb unexpected)
Height, more suitable for developing into composite material, in addition bamboo fiber has the characteristics that antibacterial, antibacterial, uvioresistant, good permeability,
It is abundant renewable resource and bamboo speed of production is fast, yield is high, it has a very strong anti-ultraviolet property, but due to
Its content of lignin is higher, causes bamboo to be generally only used for mattress class articles for use when for textile material, do not play it
Uvioresistant, excellent tensile strength and anti-microbial property.
The content of the invention
Preparation method in view of the deficiencies of the prior art, the present invention provides the fire-retardant bamboo fibre of high tenacity, this is bamboo fiber blended
The method of yarn.
The present invention is realized by following technological means solves above-mentioned technical problem：A kind of system of the fire-retardant bamboo fibre of high tenacity
Preparation Method：For other natural plant fibres, bamboo fiber has inherent advantage as the preparation of flame retardant fabric, bamboo
Lignin is higher, causes the hardness of bamboo fibre and brittleness higher, is not susceptible to renaturation bending, this is also that bamboo fibre is generally not used for
One of the reason for clothing cloth, but the higher performance that can improve flame-retardant fiber of lignin, the biomass carbon content of lignin
Higher, under the high temperature conditions, cellulose are easier to resolve into flammable gas, and lignin then may be due to Oxygen Condition
Deficiency, causes part to be fixed on the carbon on lignin and high temperature pyrolysis occurs, become inorganic carbon, relatively reduce by carbon
The imflammable gas of composition produces, and is said from this respect, the higher lifting for being conducive to fire resistance of content of lignin, and bamboo fibre
The characteristics of be：The higher xylem of content of lignin constitutes bamboo fibre, and cellulose is then distributed in around xylem.
Dry bamboo was put into the NaOH aqueous solutions containing 5~8wt% of 6~10 times of its parts by weight by the present invention before this
Then middle decoction keeps the temperature 70~80 DEG C of 30~40min of immersion to seething with excitement, the immersion of lye can remove the wax on bamboo surface with
Colloid, is conducive to the action effect after the addition of subsequent fiber element enzyme, and clear water is crossed after the completion of immersion and is rinsed 2~3 times, is shone under the sun
It is dry, the fragment that length is 1.0~1.5m is first cut into, longitudinal pressure then is imposed to bamboo fragment, is rolled repeatedly, and it is adjoint
Air blower air blast, blows away the residue for rolling, and obtains crude fine strip shape bamboo fibre.
At this moment fine strip shape bamboo fibre does not also reach the desired degree of textile cloth fiber, it is necessary to further refine
The bore of bamboo fibre, bamboo fibre at this time, appoints so there are cellulose around the bamboo fibre of xylem composition, the present invention to use fiber
The mode of plain enzyme degraded, degrades the cellulose of wood fibre surface, while refines wood fibre, reaches textile cloth fibre
The requirement of dimension, it is specific as follows：
The rough bamboo fibre of above-mentioned preparation is pressed into solid-liquid ratio 1:14~18 solid-liquid ratio is added to containing cellulase concentration
For in 1~2% aqueous solution, keep the temperature 50~60 DEG C of 2~3h of enzymolysis, the bamboo fiber residual gum content prepared by such method compared with
Small, degree of refinement is high.Due to the immersion by lye, the hydrophily higher of bamboo fibre, enzyme molecule is easier to rough bamboo fibre
Internal penetration, the range of scatter of enzyme improves, it is easier to effective collision occurs with cellulose, therefore degree of refinement increases.
Second step is to be kneaded the bamboo fibre after enzymolysis, repeatedly knead 20~30min, it is while continuous with clear water
Rinse, reduce wood fibre surface content of cellulose, while soften bamboo fibre, reach the needs of textile fiber applications.Knead
When, the pliability of bamboo fibre can be improved, the cellulose being incorporated on xylem can also be exposed, it is noted here that
Be：Because strictly controlling the time, the removal to cellulose is just right, and the final purpose of the present invention is prepared with anti-flammability
The bamboo fibre textile cloth of energy, is not that the thorough of cellulose is removed, the fiber easy fracture of Vinsol's composition, easily generation
Fiber segments, unsatisfactory for textile fabric, remaining cellulose can will preferably improve bamboo fibre between lignin
Toughness, improves the durability of finished product bamboo fiber fabric, so control time can reach optimal effect.
At this moment, the bamboo fibre that can be used for weaving purposes has tentatively been obtained, its pliability and fiber bore also reach one
Fixed requirement, then relative to flame retardant effect, not substantive raising.Therefore, the present invention will be done into one for bamboo fibre
The fire resistance lifting of step is modified.
The performance of bamboo fibre is improved using the method for maleic anhydride grafted cellulose, while improves the thick of bamboo fibre surface
Rough degree, prepares porous bamboo fibre, and in reaction kettle, bamboo fibre is pressed solid-liquid ratio 1:10~15 solid-liquid ratio is added to containing
In the xylene solution for having the maleic anhydride of 6~10wt%, 3~4h of insulation reaction under 120~150 DEG C of counterflow conditions, so
What is repeated occurs graft reaction 2~4 times by maleic anhydride and bamboo fibre surface fiber element, then washs 2~3 through deionized water
It is secondary, it is dried to obtain, is completed bamboo fibre surface fiber element success grafted maleic anhydride after dry in 50 DEG C.
