Description
Technical field
The present invention relates to chemical industry, the method that particularly a kind of biological ultrasonic wave prepares textile fabric.
Background technology
In recent years, with the increasingly depleted of fossil resources, bast-fibre is enjoyed because with good characteristics such as ecology, environmental protection
Consumer's dotes on, and its demand is increasing year by year, the global annual speedup 8% of natural fiber.Bast-fibre raw material maximum feature is fine
Dimension hplc is high, and fiber is elongated to be conducive to interweaving, and the good fiber cell of intensity is small, cell wall is thick, wall chamber is than big；Due to bast-fibre cell
Chamber is thin, fibrocyte opacity is high, and fiber is not easy wire-dividing broom purification, makes the fabric air-permeability degree being made low.
It is mainly by " cavitation effect " and " free radical activation " of ultrasonic wave using ultrasonication paper pulp fiber.
The steam that is not only produced in itself containing liquid in the bubble formed during ultrasonic cavitation, and containing being dissolved in the gas of liquid
Body.Acoustic cavitation have two kinds of effects to fiber：One is that the high-speed liquid stream that the high-strength microjet that cavitation follicular rupture is produced is formed hits
Hit fiber finer cell wall, make fiber surface be subject to mechanical impact and ultra small scale manufacture power, make fiber surface become fluffing, it is coarse, expose
, there is fibrillating and serve the effect of slight mashing in more hydrophilic radicals；Another is the high pressure that cavitation bubble collapse is produced
Or high pressure discharges the alternating pressure change of the shear stress or mechanical movement generation on the shock wave or pulsating cavity interface for producing
When acting on fiber surface, must be produced at the genetic defects of fiber stress, strain concentrate, make the primary wall of fiber finer cell wall and
Outer layer of secondary wall occur crackle, cell membrane deform with displacement and removing, there are more central layer of secondary to be exposed, fiber
Surface thus becomes coarse, increased interfibrous frictional resistance.The result is that causing the morphosis of cellulose, supramolecular structured
Structure, the degree of polymerization and its distribution change.Continue to increase the ul-trasonic irradiation time, fiber occurs the subcritical expansion of fatigue crack
Exhibition, causes crystallite dislocation, specific surface area to increase, and crystallinity declines, amorphous region increase, causes few fibers to be broken, so that fine
Dimension average length declines.Simultaneously under ul-trasonic irradiation, bleaching liquor is greatly reinforced to the run-inflation effect of cellulose, shortens medicinal liquid osmosis
Time, the hydrogen bond of cellulosic molecule interchain can be disconnected, open microcellular structure, greatly increase the internal surface area of cellulose, improve it
To the accessibility and chemical reactivity of bleaching liquor.Ultrasonication has remarkable result, fiber profit to the water retention value for improving cellulose
Swollen degree enlarged relative, fiber becomes quite soft plastic after swollen, and external surface area increase, internal organizational structure relaxes, molecule
Between cohesive force decline, be conducive to the carrying out of fibrillating.And the fiber for not removing primary wall seems smooth, stiff, not hygroscopic
Swollen.
