Background technique
Meltblown spining technology is mainly used for the production of non-woven cloth.Melt-blown non-woven technology originates from the 1950s
Just, US Naval Research Laboratory is studied and is developed and radiate in upper atmosphere after nuclear bomb explodes for collecting under government-funded at that time
The filtering material of property particle, technique is that the polymer of melting is squeezed into one by extruder to hold back in poly- thermal current, in gas
The superfine fibre formed under the stretching action of stream is blown to solidifying wire stitcher, to be piled into a kind of ultrafiltration material.The technique is
The blank of modern melt-blown non-woven technology.Middle 1960s, Exxon company, the U.S. improves this method, into
Enter to switch to this technology the seventies civilian, and combine with University of Tennessee, the U.S. and to establish non-woven material and develop research and development centre,
Melt blown technology enters production, teaching & research developing stage.The 1980s, melt-blown non-woven material are protected in global rapid development
The annual growth for having held 10%~12%, the development advanced by leaps and bounds.
Melt blown non-woven is to succeed in developing first in the U.S. the 1950s, China also once the beginning of the sixties into
Went development.It, at cloth, is a kind of new high-tech product by the polypropylene chip direct fabrics of high fusion index.
Melt blown nonwoven process flow are as follows: polymer chips melted by heating in screw extruder, melt are transported to
In the spinneret orifice of spinneret, leave the polymer melt of spinneret orifice formed under the strong drawing-off effect of high-speed and high-temperature airflow it is ultra-fine
Long filament or micro staple fiber, and melt-blow fiber web is formed at lace curtaining or reception roller with flow deposition.
Melt-blown process is polymer melt after squeezing out in die head, by the effect of velocity heated gas, in polymer jet stream
Before cooled and solidified, polymer jet stream is stretched using high-speed flow, directly forms superfine fibre nonwoven on the reception device
A kind of processing technology of cloth.
The diameter of business meltblown fibers is usually 1~10 μm, and laboratory can have been prepared using melt blown technology at present
Meltblown fibers minimum diameter is lower than 0.6 μm, belongs to nanofiber.Enter after spinneret extrusion in high-speed and high-temperature airflow field and fast
Speed stretches and tapers to micro nanometer fiber.
The fiber feature of melt blown non-woven be it is ultra-fine, fibre diameter minimum can reach 0.5 μm, generally at 1~5 μm
Between, fiber is thinner, and the quality of non-woven cloth is better, but the opposite reduction of yield.
The diameter of meltblown fibers is very thin, and the aperture of large specific surface area and fibre web is small, melt-blown non-woven product its have it is superior
Particle column section, the performance of particle-capture and warmth retention property.Meanwhile product is meltblown there are also unusual capillarity and is breathed freely
Property (water and blood are impermeable and vapor can permeate).For this purpose, melt-blown product is also widely used as filtering material, warming material
Material, hygienic material, medical material etc..
Polymer is fed from feeding funnel, drives the screw extruding screw thread of rotation to push before machine barrel from screw motor
Side is successively equipped with the heating region of different temperatures by 5.Polymer temperature in machine barrel can gradually rise, physical state
Also it is elastomeric state by glassy transition, finally becomes viscous state, reach complete melting.Screw rod stablizes rotation by certain speed,
Uniform molten polymer is isobaric, is equally transported to spinneret.The polymer streams squeezed out after the hole diameter of spinneret are flowed through to pass through again
Micro nanometer fiber is made in two strands of high-temperature high-speed airflow drawing-off molten polymers.
