Abstract
The invention relates to a method for preparing staple fiber melt-blown webs, wherein it is characterized in that: it has a step for adhering staple fiber that heating and compressing the polymer resin slices into melt state, via the distribute channels, to be extruded at the front blown hole of ejector, and the staple fiber via the airflow will be adhered with un-solidified beam, to be drawn, cooled and solidified, to be deposited on the collector, to be coiled into network. Via the skeleton function of staple fiber, the product has better flexibility and heat insulation.
Description
Technical field
The present invention relates to a kind of preparation method who contains the staple fibre melt spraying non-woven fabrics, belong to textile technology field.
Background technology
Melt blown non-woven has obtained development rapidly after the seventies drops into suitability for industrialized production.The difference of it and filature fleece formation method non-weaving cloth is in the fibre web that fiber is not continuous filament yarn shape but staple fibre shape, and the fineness of fiber is low simultaneously, has only the 2-4 micron.
Owing to be superfine fibre, this non-weaving cloth is particularly suitable for doing products such as filtering material, battery interlayer, insulating materials, oil absorption material, synthetic leather base and fine paper.
Fig. 2 is a melt blown non-woven production technology schematic diagram, and Fig. 3 is a nozzle schematic diagram wherein.Section is heated in extruder 1 and pushed the formation polymer melt to enter in the extrusion chamber 3 of nozzle 2, extrude by the flat spinneret orifice 4 of a row, import from conduit 7 by the high speed thermal current of air blast 5 through air heater 6 heating, from the spinnerets flat slit high speed ejection of both sides up and down, be subjected to dispersion, the stretching action of high velocity, hot air from the polymer of squit hole 4 ejection, form ultra-fine staple fibre, aggegation is on lace curtaining 8 with fixed attention, form fibre web, be wound into yardage roll 9.
After the material of section was selected, nozzle temperature, hot air temperature just determined, for the common air themperature of polypropylene than the high 500F of nozzle temperature about.After product is quantitatively determined, coagulate the movement velocity of lace curtaining and the speed of extruder and just determined that the main technologic parameters that therefore influences the non-weaving cloth performance is the air pressure of nozzle.
The diameter of fiber reduces with the increase of air pressure.This is because under the constant situation of orifice diameter, air pressure increases, air velocity and jet amount increase, and the speed that polymer sprays from spinneret orifice is not subjected to the influence of air pressure, one timing of extruder extrusion speed, and the polymer velocity of spinneret orifice ejection is certain, thereby polymer is after the spinneret orifice ejection, because of air velocity improves, the air drawing multiple that is subjected to strengthens, so the diameter of fiber reduces.
Existing melt spraying non-woven fabrics in preparation process, is that staple fibre is added in superficial layer, in use for some time, be compacted gap smaller in the nonwoven fabric construct or disappearance easily, cause the flattening of stereochemical structure, make nonwoven fabric elasticity weaken, bulkiness diminishes, the warmth retention property variation.
Summary of the invention
The object of the present invention is to provide a kind of preparation method who contains the staple fibre melt spraying non-woven fabrics.
Existing melt spraying non-woven fabrics is after the fluoropolymer resin section is become molten state by the extruder heating and pressurizing, extrude through the spinneret orifice that melt distributes runner to arrive the shower nozzle front end, make it super-refinement through gas stretching again, the fiber cooling curing of super-refinement is deposited on the collecting net equipment, be wound into net, promptly obtain melt spraying non-woven fabrics; The difference of the method for the invention is to have increased a staple fibre step for adhering, that is, melt is after spinneret orifice is extruded, and staple fibre is under the air-flow effect, and is bonding with still uncured tow.
Staple fibre addition in the said process is the 15-30% of nonwoven fabric weight, is preferably 25%.
Described staple length is 20-40mm, and fibre diameter is dtex1.5-4, and described staple fibre can be a natural fabric, also can be artificial fibre, preferred terylene, polypropylene fibre or viscose.
Above-mentioned polymer raw material can be polypropylene, polyester, modified poly ester (PBT, PTT) or polyurethane; Optimization polypropylene.Polyurethane can be used for melting and spraying the production of stretch nonwoven.
Spinning pressure is generally 0.30-0.35Mpa.
Gas jet pressure when bonding should exceed 0-0.05Mpa than spinning pressure to above-mentioned staple fibre with tow, preferred 0.05Mpa; Gas temperature should be controlled at 150-200 ℃.
Melt spraying non-woven fabrics wire vent direction and staple fibre injection direction are 10-40 degree angle, preferred 30 degree.
The inventive method adds staple fibre in the melt spraying non-woven fabrics production process, skeleton function by means of staple fibre, make existing melt spraying non-woven fabrics realize lifting aspect elasticity, bulkiness, the thermal property, having solved existing melt spraying non-woven fabrics is compacted easily, in use for some time, lack flexibility, bulkiness, to such an extent as to the problem that warmth retention property reduces.
Researcher of the present invention finds, in the staple fibre adhesion step of increase, when the staple fibre addition be nonwoven fabric weight 25% the time, the cohesiveness and the flexibility of nonwoven fabric are best, the durability of corresponding thermal property is also best; Surpass at 30% o'clock, the poor adhesion of the two, staple fibre begins to come off; And the staple fibre addition is during less than nonwoven fabric weight 15%, and staple fibre and nonwoven fabric are only bonding on the surface, do not reach the object of the invention.
Use the nonwoven fabric that the inventive method makes, under same case, be processed into clothes, through pressurization for a long time with existing nonwoven fabric, under the identical condition of ambient temperature, solar radiation is used in the clothes of the nonwoven fabric that the inventive method makes temperature than the high 2-6 of existing nonwoven fabric ℃, 4 ℃ of mean heights.This experimental result reflects that the nonwoven fabric that application the inventive method makes has promptly been kept good thermal property because the skeleton function of staple fibre has kept bulkiness preferably, and the function superiority obviously is better than existing melt spraying non-woven fabrics.
