Description
Technical field
The present invention relates to material for water treatment technical field more particularly to a kind of preparation sides of water process composite fibrofelt
Method.
Background technique
Fibrous felt materials are a kind of novel filtering materials, due to intertwineing with each other between its fiber, have unique stereoscopic graticule
Shape structure and the slight void being much evenly distributed, and since the specific surface area of fiber is very big, it can be heavy by interception, inertia
A variety of different mechanism such as product, gravitational settling are filtered, and filtration resistance is low, filter effect is high, at low cost, therefore obtains in environmentally friendly water treatment field
To being widely applied.Currently, common water process is to pass through the methods of melt-blown system with high molecular materials such as polypropylene with fibrofelt
At although these high molecular material performances are relatively stable, its hydrophily is poor, imitates to the Adsorption of pollutants many in water
Fruit is bad, and environmentally friendly poor compatibility, not easy to handle after use, is easy to bring burden to natural environment.Natural fiber is as one
Kind source is wide, price is low, good hydrophilic property, reproducible living resources, is a kind of water process fibrofelt of great exploitation potential
Material.But natural fiber has the shortcomings that degradable, mechanical performance is low, poor selectivity, limits its using effect, operation
Stability and service life.Therefore, it is necessary to make improvements.
Summary of the invention
The object of the invention is to remedy the disadvantages of known techniques, provide a kind of adsorption effect is good, operation stability is high,
The preparation method of water process composite fibrofelt with long service life.
The present invention is achieved by the following technical solutions：
A kind of preparation method of water process composite fibrofelt, includes the following steps：
（1）Flaxen fiber is subjected to networking with random web-laying equipment after degumming, combing, shredding processing, it is then upper and lower through needing machine
Radix zanthoxyli thorn, obtains bast fibre felt after cutting；
（2）First by step（1）Obtained bast fibre felt is in the acetum for being equivalent to 10-20 times of bast fibre felt weight at immersion
2-4h is managed, is then washed with deionized to neutrality, then in the cellulase solution for being equivalent to 10-20 times of bast fibre felt weight
Enzymolysis processing 1-2h, it is dry complete after being washed with deionized, obtain modified bast fibre felt；
（3）By step（2）Obtained modification bast fibre felt addition is equivalent to modified 10-20 times of bast fibre felt weight of biomimetic mineralization
In liquid in 36-37 DEG C immersion 3-5 days, after taking-up it is dry completely, obtain water process composite fibrofelt.
The flaxen fiber is sisal fiber, hemp or ramee.
The mass fraction of the acetum is 0.3-0.5%.
The step（2）The temperature of middle immersion treatment is 40-60 DEG C.
The mass fraction of the cellulase solution is 0.5-1%.
The step（2）The temperature of middle enzymolysis processing is 30-35 DEG C.
The preparation method of the biomimetic mineralization liquid is by 0.35-0.37 parts by weight calcium chloride and 0.22-0.24 parts by weight phosphorus
Acid dihydride sodium is added in 100-150 parts by weight water, and pH is then adjusted to 7-8, obtains biomimetic mineralization liquid.
The step（2）In drying temperature be 100-120 DEG C.
It is an advantage of the invention that：
Flaxen fiber is first carried out networking with random web-laying equipment after degumming, combing, shredding processing by the present invention, and then needle pierces, divides
Bast fibre felt is obtained after cutting, then handled by acetum acid soak combine with cellulase solution enzymolysis processing to its into
Row is modified, and is finally used biomimetic mineralization liquid immersion treatment, is obtained water process composite fibrofelt after dry.The present invention is made with flaxen fiber
For basic raw material, first passes through acid processing and enzymatic treatment carries out Partial digestion to it, increase the hole on flaxen fiber surface and inside
Diameter increases specific surface area, improves the adsorption capacity of fibrofelt, then uniform on fibrofelt surface and inside with biomimetic mineralization method
Nanometer hydroxyapatite is loaded, improves the adsorptive selectivity and mechanical performance of fibrofelt, while fibrofelt being made to be not susceptible to drop
Solution, improves its stability in water body, to improve the operation stability and service life of fibrofelt.It is prepared by the present invention
Water process is not easy to degrade in water with composite fibrofelt, and adsorption capacity is big, adsorptive selectivity is high, has good using effect
Fruit, operation stability and service life.
Specific embodiment
A kind of preparation method of water process composite fibrofelt, includes the following steps：
