Description
Technical field
The present invention relates to textile fiber technical field more particularly to a kind of anti-radiation nano-oxide modified plant fibers
Fabric and its manufacturing method.
Background technique
Anti-radiation fiber in routine techniques generally refers to have radiation resistance outstanding to ray and neutron current etc.
Fiber.Under normal conditions, anti-radiation fiber has the performances such as good high temperature resistant, resistance to combustion and corrosion resistance.
All at present three kinds of anti-radiation fibers or fabric have its apparent limitation: the first, coating cloth, dress
It is airtight, it can't wash, be not suitable for people's dress.Second, metallic fiber cloth, this material is due to the wire in fabric
Be it is superfine, clothes can inevitably be wiped and be touched, especially cleaning when be easy rubbing, stave metal mesh.Once wire peels off or goes out
Existing broken hole can seriously affect the shielding property of metallic fiber or even can stab skin, along with its texture is not very good,
Harder, easy diaphragm answers skin.The third, silver fiber cloth, the unique disadvantage of silver fiber is exactly to be oxidized easily, and metallic silver is pole
It is easily oxidized, the time being exposed in air is easy for very much reacting with the substance in air long, and cloth is caused after oxidation
Jaundice obfuscation.
Therefore, it is badly in need of that a kind of security ventilating, high plasticity, high-flexibility, skin-friendly be good, water-fast acidproof, antioxygen on the market
The fabric and its manufacturing method of change.
Summary of the invention

Citric acid antimony solution, 12 parts of -15 parts of nano titanium dioxide powders, 60 part -65 of 10 parts of -11 parts of Solute mass concentration 8%-10%
The sodium silicate solution of part mass fraction 20%；
2) skeleton manufactures
1. by the stage 1) moso bamboo that 1. prepares of step is placed in water and boils 1h-1.5h, then take out using hydraulic-driven
Metal post mechanical is squeezed into item, until broken bamboo cane diameter of 1 mm-3 mm, obtains former material moso bamboo item；
2. 1. former material moso bamboo item that step obtains is in 2MPa-2.5MPa steam pressure, 130 DEG C -135 DEG C of vapor (steam) temperature ring
It is boiled in a covered pot over a slow fire under border and steams 25min-30min, then the bamboo cane after stewing steaming is totally immersed in biological enzyme aqua and carries out degumming process, will be taken off
The bamboo fibre network management mechanical carding of the removal colloid obtained after glue obtains hard bamboo silk at silk；
3. 2. hard bamboo silk that step is obtained immerses in the hypo solution of mass fraction 0.04%, continue 1.5h-
2h takes out softened hard bamboo silk, bamboo fibre skeleton needed for obtaining；
3) composite fibre to be arranged
1. in the stage 2) the bamboo fibre skeleton that 3. obtains of step take out half at same direction close-packed arrays put neatly,
Uniformly paving spills the stage 1 on bamboo fibre skeleton) nano titanium dioxide powder that 1. prepares of step, then in nano titanium dioxide powder
On close-packed arrays residue bamboo fibre skeleton at same direction again, obtain composite fiber core；
2. by the stage 1) the nitric acid solution of tin that 1. prepares of step and citric acid antimony solution is mixed into reaction solution, 1. by step
The composite fiber core of acquisition is immersed to reaction solution bottom, is obtained mixture, then mixture is put into vacuum environment, by adding
Heat makes solution become fluidized state, obtains boiling mixture；
3. constantly instilling the concentrated nitric acid and matter of mass fraction 68% respectively in the both ends of 2. boiling mixture that step obtains
The volume drop rate of the aqueous citric acid solution of amount score 50%, concentrated nitric acid and aqueous citric acid solution keeps the stabilization ratio of 1:1.5
Example, keeps the fluidized state of solution, stops drop when the 42% of reaction solution total volume when the total volume of the acid solution of dropwise addition reaches original
Add, then proceed to keep heating, until boiling mixture gross mass stops heating when being 12 times of former composite fiber core gross mass, obtains
Composite fibre must be acidified；
4. 3. acidification composite fibre that step obtains is completely immersed in the stage 1) in the sodium silicate solution that 1. prepares of step, to
Sodium silicate solution is heated after the reaction was completed, until mixing pension gelation, obtains composite fibre to be arranged；
4) product manufacturing
1. in the stage 3) composite fibre to be arranged that 4. obtains of step do not complete solidify it is preceding with the stage 3) 1. step obtains
Composite fiber core is the strip that center main body extracts the solidifying state lactic acid-gel of surface layer attachment half, and by every strip according to setting
Meter size is hot extruded into required fiber size structure until curable type is completed, and acquisition composite fibre is woven into using the composite fibre
Fabric be needed for fabric.
Compared with prior art, the invention has the following advantages that nano-titanium dioxide used in (1) present invention is light touching
Matchmaker's sterilization material, to bacillus subtilis black variety gemma, Pseudomonas aeruginosa, Escherichia coli, gold-coloured staphylococci, Salmonella
The killing rate of bacterium, tooth branch bacterium and aspergillus reaches 98% or more；Meanwhile it can absorb ultraviolet light and reflection, scatter it is ultraviolet
Line, moreover it is possible to penetrate visible light, be the ultra-violet protecting agent of superior performance, extremely promising physical shielding type.(2) of the invention
Only there is the fibrous material functional material of simple function different from the prior art, but integrated by technological design and production technology
And the vacuumizing of the high gas release process in part realize functional particles it is decentralized, homogenization and activation (root is it was found that root
The nano-oxide particles average grain diameter generated according to production technology of the invention is in 10nm or so, for non-present invention production
Nano-titanium dioxide can also accomplish that uniformity is fabulous, and dispersion degree is high).(3) process integration of the invention is very high, real at the same time
It is also protected while existing highly conductive (low-resistance bis- structure antimony oxides of tin oxide -), high radiation preventing sterilizing (nano-titanium dioxide) function
Having demonstrate,proved the high skin-friendly of matrix and high tenacity and high plasticity, (table of colloidality fiber mutually to knit present invention could apply to various
