Abstract
The present invention is the improvement to existing one-step method and two-step process plastic Nonwovens forming method.Existing one-step method is to extrude the fusion cotton ginning, and vertical, horizontal hot-stretch, bonding goes on foot into cloth, but the Nonwovens vertical, horizontal intensity and the pattern structure that make are inconsistent, and is not suitable for vinyon.And existing two step method has the complex structure through, the netted silk of broadwise right angle Orthogonal Composite machine, the shortcoming of the synchronous coordination difficulty of longitude and latitude again.
The present invention is to be raw material with polyolefin, and through film extrusion, the molding process that becomes of orthogonal plastic Nonwovens with vertical transverse strength and grid unanimity is made in cutting, longitudinal and transverse stretching, the heat bonding of forward fitting.
Description
The invention relates to the new improvement of plastics Nonwovens production method.In detail, the present invention is that employing is that raw material is made laminated film with high low density polyethylene (LDPE), after cutting, a part is as vertically hot-stretch, a part is as laterally hot-stretch, have cancellated flat filament thereby make vertical and horizontal respectively,, forward relatively fit and heat bonding makes and has in length and breadth two forming methods to the plastics Nonwovens of network the netted flat filament of longitude and latitude.
The Nonwovens of indication of the present invention is that a kind of employing crystalline polymer polymer is that raw material is made laminated film through cutting, stretch and make and have in length and breadth to cancellated flat filament, forward bonding a kind of need not the passing through of lamination spinned then, braiding forms the new packaging material of cloth, that this Nonwovens has is in light weight (50 grams/square metre), and intensity is big, characteristics such as ventilative, with it and paper, plastic sheeting, foamed plastics, make various compound package materials after metal forming etc. are compound, make the lower material of the original strength ratio raising use value that is enhanced, be widely used in fertilizer and pesticide.Particularly replace traditional brown paper bag of cement, thereby can save a large amount of foreign exchanges and timber, and can reduce the broken rate and the packing cost of cement.In addition, can also be used to grow seedlings booth, rain cover etc. later with film is compound, its purposes is very widely.Owing to make this Nonwovens, need not spin cotton and weave cloth, thereby can simplify technology and equipment greatly, reduce plant area and labour, reduce energy consumption and investment, and efficient is higher 50～100 times than traditional braiding machine.
Prior art, one-step method of U.S. Patent number uspat371950 etc. for example, its basic skills is, thermoplastic molten is extruded, then respectively by a pair of scoring roller, wherein one is carved with the horizontal ridge design and the vertical scoring roller of ridge design, and another is a smooth roll.All logical cold water cooling in the roller makes respectively and has the horizontal ridge design and the vertical reticulated film of concavo-convex decorative pattern, and then stretches through horizontal expanding respectively and vertical uniaxial tension and make the cancellated flat filament of vertical, horizontal.Another embodiment of said method is that the melting charge that will extrude is by a pair of scoring roller with the ridge design at oblique angle (45 °) angle, make reticulated film with 45, then earlier through longitudinal stretching, and carry out horizontal expanding to stretch and made the netted flat filament with 45, with this netted silk shop bonding orthogonal Nonwovens that becomes 45 ° of drift angles that changes of fitting relatively at an angle of 90 mutually.This drift angle orthogonal Nonwovens should not be as heavy packing articles, because after being subjected to tension, and the component that 45 ° of drift angles produce and the two-layer flat filament after bonding is peeled off mutually.Destroyed the integrality of network structure and Nonwovens.Above method is commonly referred to one-step technology.
But above-mentioned forming method exists following shortcoming:
1. existing one-step method of melting cotton ginning technique usually need be bonding with adhesive, so technical process is complicated.
2. its cooling means of the flat film of ridge design of making of fusion cotton ginning must be paid close attention to, and often owing to cooling is not good at making the inner spherocrystal diameter that forms of flat film bigger, has influenced the quality of flat film.
3. the fusion cotton ginning technique only is applicable to and extrudes flat membrane process craft, is not suitable for the tubulose membrane process craft.
4. the ridge design of fusion cotton ginning formation can not cutting thoroughly be seen bright, often recess leaves the film of connection, though to the no much influences that stretch, but the netted flat filament after stretching, outward appearance is not good enough, distinct issues are the most: the network and the intensity of the Nonwovens vertical and horizontal that make with said method are inconsistent, have influenced the scope of application.
Existing now the employing with high low density polyethylene (LDPE) is raw material, make laminated film with high low-melting two-layer coextrusion, because high low density polyethylene (LDPE) has structural similar characteristics and better chemical affinity, so the laminated film of making has cohesive force preferably, and because height poor on the fusing point, for example low density polyethylene (LDPE) can be lower than the fusing down of 20 to 30 ℃ of high density polyethylene (HDPE)s, and moment solidify can cool off the time, thereby has solved in length and breadth the adhesion problem to netted flat filament.Be main raw material with the high density polyethylene (HDPE) in addition, have better tensile strength.
It's a pity that this raw material yet there are no in one-step method Nonwovens forming method and use.But in the two step method forming method, successfully use.So-called two step method is exactly only to use a kind of laminated film, at first through vertically cutting, vertically uniaxial tension makes netted flat filament, second the step again with the netted flat filament of this stretching respectively as warp-wise and broadwise base material, spread repeatedly lamination heat bonding and make Nonwovens with a longitude and latitude right angle Orthogonal Composite machine, this method is at first by Japanese Process Technology of Polymer research institute's invention and the power of patenting, its patent No. in the U.S. is uspat 4052242, this successful invention be utilize high density polyethylene (HDPE) for the Nonwovens moulding process of raw material opened one new by way of, this method is exactly the method that cloth is cut in the used manufacturing of Nippon Oil(Nippon Mitsubishi Oil) chemical company " day stone Wa Lifu ", the great advantage of this two step method forming method, the one, adopted the heat bonding of high low density polyethylene (LDPE) composite membrane, the 2nd, can make through the broadwise network Nonwovens consistent with intensity.
But existing two step method still has following weak point
1, owing to be the stretched attenuation that attenuates, thereby cut off when broadwise and to carry and the shop repeatedly and in the bonding process is easy to be disarrayed, and warp-wise and the synchronous coordination action of broadwise is more, be difficult to make combination shop carrying out at a high speed repeatedly through the netted flat filament of broadwise.
2, the structure of warp, latitude unit mahine is comparatively complicated, be that toughness liquid is picked up in dependence and unsteady conveyer belt has been picked up or carry out the orthogonal shop repeatedly in broadwise cut-out and conveying by means of the method for machinery, deliver into bond roll then continuously and carry out heat bonding, make the plastics Nonwovens, simultaneously also will be with processes such as viscosity fluidity flush awaies so operation is complicated.
The present invention is intended to utilize existing high-speed lamination shop characteristics repeatedly of melting the horizontal expanding stretching of cotton ginning and vertical uniaxial tension one-step method system Nonwovens, utilized the bonding advantage of high low-melting composite film heat in the two step method again, both overcome plastics Nonwovens in the existing one-step method through broadwise network and the inconsistent shortcoming of intensity, avoid the longitude and latitude right angle Orthogonal Composite machine that uses structure comparatively complicated again.This shows that the present invention is a kind of improvement to existing one-step method and two-step process.
Basic skills of the present invention is:
1, adopting high density polyethylene (HDPE) (about 137 ℃ of fusing point) is main raw material, and low-density polyethylene (105～110 ℃ of fusing points) is made laminated film as bonding film, have the poor of high low melting point, when bonding, just can in bonding process, overcome and use chemical adhesive or the many shortcomings of the high operation of thermosol adhesive cost like this.
2, utilize horizontal expanding to stretch and vertical uniaxial tension, forward fit to netted flat filament continuous one-step in length and breadth then, the low melting point rete under heating condition at first fusing make through the broadwise twine and be melt into one, then through behind the cooling curing and make through, the broadwise net is glued together becomes the plastics Nonwovens.
3, the present invention's is to cut with same cutter sweep and cutter to the cutting reticular membrane that stretches in length and breadth.So its cancellated decorative pattern is identical, and can make horizontal nethike embrane and vertically nethike embrane all be only to be orientated just to make the Nonwovens that makes consistent through the broadwise intensity one grid decorative pattern of making peace through uniaxial tension.The method of implementing is: just cut off a piece reticulated film that becomes certain width with vertical cutting back for the cross directional stretch reticulated film, with the reticular membrane of this cut-out.Press 90 and spend the angle conversion directions, and deliver into the expanding stretching, so in fact just make in length and breadth to all being the stretching of process uniaxial orientation.
4, change direction owing to carry out 90 degree angles after the netted cutting film stripping and slicing that will not stretch, so have well-pressedly, breadth is little, is difficult for disarraying, and relatively the gossamery netted flat filament that usefulness has stretched in the two step method makes things convenient for manyly, and efficient is also much higher.This just provides advantage for high-speed production.
5, because horizontal netted flat filament of the present invention is to enter under the clamp position of expander clip Yu from the expander bottom, and the vertical netted flat filament that is in tension is fitted along same traffic direction lamination.(i.e. shop repeatedly) then again under this state heating the low melting point film is melted after the bonding plastics Nonwovens that becomes of pressing cooled and solidified, suitably adjust the transverse cuts decorative pattern and longitudinally mesh-density just can make the Nonwovens of multiple style and multiple product.
Main feature of the present invention is, it avoids using baroque longitude and latitude unit mahine in the two step method, thereby brought into play again simultaneously and made the broadwise net high speed that is in the warp-wise net under the tension state of the quadrature bonding regularity uniformity that has kept network of lamination of forward fitting that under clamp position, meets at right angles in the one-step method with it, the present invention is the cutting decorative pattern that only uses with a kind of composite membrane and same structure to stretching in length and breadth once more, so product has intensity unanimity in length and breadth.The network unanimity, so the present invention has practical value.
In order to reach above-mentioned projects, the present invention realizes by the following method:
1. raw material is selected for use:
Above-specified high density polyethylene (HDPE) can be with the product in chemical plant, homemade Liaoyang.The trade mark is GF7750 or imported raw material, for example Japanese 5000S that produces, West Germany raw material GF7750 etc.Several raw material technical parameters are as follows:
Trade mark melt index density fusing point ℃ factory
Chemical plant, GF7750 0.5-0.4 0.940-0.950 137 Chinese Liaoyang
5000S 0.75 0.955 135 Japan
GF7750 0.5 0.95 137 West Germany's Hirsts
Require the HDPE raw material that the narrower range of molecular weight distributions of higher molecular weight (about 100,000) is arranged.Less density gradient and higher crystallinity.
The general available homemade low density polyethylene (LDPE) of LDPE, its fusing point requires between 105-110 ℃, and MI is between 3～5, and melt viscosity is close between the high low density polyethylene (LDPE).
2. system film:
(1) in order to make the laminated film of two-layer coextrusion, except that selecting proper raw material, also should select rational handpiece structure and temperature control system.
(2) with the coextrusion blow molding process or extrude flat membrane process and make composite tube film and compound flat film.
(3) tubular film should adopt lower blowing method, and again through the water ring cooling, flat film direct water-cooling method improves cooling effect, improves film quality through a vane cooling.
3. cutting:
Tubular film peace film all can adopt me " the barbed type cutting tool " of invention to cut.
4. direction is changed in the cut-out of cross directional stretch nethike embrane piece:
Volume one of in the above-mentioned reticular membrane that has cut earlier along transversely with the reticular membrane piece of electric heating cutter stripping and slicing becoming Rack, is entered horizontal expanding stretching-machine by changing direction mechanism then.
The laterally stripping and slicing and the commutation of reticular membrane piece, available following two kinds of methods.The one, earlier with above-mentioned vertical cutting reticular membrane, press every 160 to 180mm apart from cut-out as cross directional stretch.And be piled into certain height (attention faces down low melting point one) and change direction then and be placed on adding in the film trap of expanding stretching-machine front end, by adding the sheet machine with the above-mentioned reticular membrane piece that has changed direction, one then plot send in the clip of clamping band of expander, and promptly be held, enter the preheating zone, this method is intermittently adding the sheet method, and is comparatively simple.
The 2nd, the above-mentioned reticular membrane that has cut into annular ribs is sent in the electric cutter tool of rotation continuously, be cut into 160 to 180mm the film piece of being separated by, then be transported to end, and slide among the chute of carrying along the commutations at 90 degree angles by swash plate by conveyer belt.Promptly be recycled the pressure holding of pressure holding band then, the clip that enters into the clip band on expander both sides is held, and enters preheating section then, and this method is adding the sheet method continuously.
5. identical for the netted pattern structure that makes the reticular membrane that vertical and horizontal stretch, the present invention recommends following two kinds of methods: first method is the tubulose embrane method, tubular film doubling flattening is become bilayer film, the once double-deck double-deck reticular membrane that is cut into certain decorative pattern.Two-layer about dividing then, the upper strata stretches as horizontal stripping and slicing commutation and horizontal expanding, and lower floor supplies vertical uniaxial tension.
Second method is flat embrane method, carries out cold cut with one group of extruder (two) after extruding cooling under the stable condition and cuts, and the rolling rolling is used separately as horizontal and vertical stretching reticular membrane with two volume reticular membranes then.Perhaps use two groups of extruders (each two) to supply cross directional stretch for one group, one group supplies longitudinal stretching, makes the rotary speed of two groups of extruded velocities, cutting tool pattern structure and cutter in full accord, can make the reticular membrane of two groups of decorative pattern unanimities equally.
More can obtain the in full accord of pattern structure with the tubulose embrane method in the above method.
6. in order to reach the draw ratio unanimity, thereby make the intensity unanimity of vertical and horizontal netted flat filament.The multiple that horizontal expanding stretches is fixed, if adjust the longitudinal stretching multiple just can make after the stretching in length and breadth to the intensity unanimity of the netted flat filament of stretching.
7. in order to be converted to horizontal cutting decorative pattern by vertical cutting decorative pattern as the reticular membrane cutting decorative pattern of cross directional stretch, the film that must vertically cut decorative pattern is a piece reticular membrane of 160 to 180mm along laterally being cut into width earlier, carry out then 90 the degree angles change direction make the cutting decorative pattern be transformed into along transversely arranged, carrying out vertical uniaxial tension like this and stretch to expanding, all is uniaxial tension.
It shown in the figure one schematic diagram of this cut-out and changement, the reticular membrane (1) that has cut into annular ribs is unreeled by carry-over pinch rolls (2) traction, entering alloy-steel cutter (6) alloy-steel cutter through conveyer belt (3) heats with electric heater (7), when reticular membrane passes through cutter, cutter is rotated to the central point (normotopia) of cutting by swivel mount (5), reticular membrane is heated to melt between the liner roll (8) and the edge of a knife and cuts off, the nethike embrane piece that cuts off is thrown off the reticular membrane volume by the traction of pressure holding conveying roller (10).Cut reticular membrane piece is transported to the end of conveyer belt by conveyer belt (14), slips in the lateral transfer groove (16) by swash plate (15).Be provided with transverse onveyer (18) in the delivery chute when the nethike embrane piece slips into the lateral transfer groove by swash plate, promptly carry and leave transverse groove by conveyer belt (18), behind an output transverse groove of mesh patch, promptly to horizontal expander and carry by clamping conveyer belt (a 25) clamping, the clip that is opened on the track of expander both sides fast on the clamping band (22) of openning clamps, enter into preheating section (38) expanding stretch section (39), heat-setting section (40) then successively, and make the netted flat filament (41) of cross directional stretch.
When adopting add the sheet method intermittence, can be undertaken by shown in the figure two: the stripping and slicing and the said method of reticular membrane are identical, after just the net piece of stripping and slicing being stacked into certain altitude, send into and add the sheet device, (36) for adorning the heaping groove of net piece, promotion back and forth by the promotion rubber wheel (29) of non-return (ratchet) makes reticular membrane piece (35), send into transverse onveyer (25) one by one, dancer (37) can lifting, when accumulation net piece is lower than the conveyer belt nip rolls, rise by dancer, the net piece is imported conveyer belt (25), make then clip band (23) centre that is transported to the expander both sides fast continuously of one of reticular membrane by conveyer belt (25) and clamping conveyer belt (27).Simultaneously the mesh patch both sides respectively by about clip (22) on the two clip bands (23) clamp ， And and enter preheating section (38).Expanding stretch section (39) and heat-setting section (40), and make the netted flat filament (41) of cross directional stretch.
Below be that embodiment of the present invention are given an example:
Example one: make fine one step processing method by the tubular composite membrane cutting:
