Description
Technical field
The present invention relates to chemical industry, especially a kind of method that biological ultrasonic wave prepares textile fabric.
Background technology
In recent years, with the increasingly depleted of fossil resources, bast-fibre is received because having the good characteristics such as ecology, environmental protection
Consumer's dotes on, and demand is increasing year by year, the annual speedup of global natural fiber 8%.Bast-fibre raw material maximum feature is fine
Dimension hplc is high, and fiber finer length is conducive to interweave, 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, keeps manufactured fabric air-permeability degree low.
It is mainly " cavitation effect " and " free radical activation " by ultrasonic wave using ultrasonication paper pulp fiber.
The steam not only generated containing liquid itself in the bubble formed during ultrasonic cavitation, but also contain the gas for being dissolved in liquid
Body.There are two types of effects to cellulose for acoustic cavitation：First, the high-speed liquid stream that the high-strength microjet that cavitation follicular rupture generates is formed is hit
Fiber finer cell wall is hit, makes fiber surface by mechanical impact and ultra small scale manufacture power, so that fiber surface is become fluffing, coarse, exposes
More hydrophilic radicals occur fibrillating and play the role of slightly being beaten；Another is the high pressure that cavitation bubble collapse generates
Or the alternating pressure variation of the shock wave or shear stress or mechanical movement generation on pulsating cavity interface of high pressure release generation
When acting on fiber surface, must be generated at the genetic defects of fiber stress, strain concentrate, make fiber finer cell wall primary wall and
Outer layer of secondary wall is cracked, cell wall deforms with displacement and removing, there are more central layer of secondary to be exposed, fiber
Surface thus becomes coarse, increases interfibrous frictional resistance.As a result, leading to the morphosis of cellulose, supramolecular structured
Structure, the degree of polymerization and its distribution change.The ul-trasonic irradiation time is continued growing, the subcritical expansion of fatigue crack occurs for fiber
Exhibition causes crystallite dislocation, specific surface area to increase, and crystallinity declines, and amorphous region increases, and few fibers is caused to be broken, to fine
Average length is tieed up to decline.Simultaneously under ul-trasonic irradiation, bleaching liquor greatly reinforces the run-inflation effect of cellulose, shortens medicinal liquid osmosis
Time can disconnect the hydrogen bond of cellulosic molecule interchain, 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 increases, internal organizational structure relaxation, molecule
Between cohesive force decline, be conducive to the progress of fibrillating.And the fiber for not removing primary wall seems smooth, stiff, not hygroscopic
Swollen.
