2. description of the prior art

Technique for the manufacture of nonwoven products is existing for many years.In a kind of technique, process fiber fur layer or fiber web with water line or water jet, to impel fiber entangled to each other and to improve fibroreticulate physical property such as intensity.This technology utilizing water jet to carry out processing has many decades, as from U.S. Patent No. 3, and 214,819, No.3,508,308 and No.3,485, the technology can recognized in content disclosed by 706.

In brief, this method relates to and utilizes the effect of high-pressure water jet that elementary fibril is interweaved mutually, and high-pressure water jet is similar to needling action on fiber construct, and can make the fibroreticulate few fibers reorientation of formation at thickness direction.

Current this technology extensive exploitation, and, not only for the production of known " water thorn (spunlaced) " or " Hydroentangled (hydroentangled) " structure, for the uses of fabric of such as especially medical field and hospital application, for wiping, filter, and the packaging of tea in bag, and, the article obtained can be rule and uniform, as from U.S. Patent No. 3, 508, the disclosure content of 308 can be recognized, and, if needed, the article obtained comprise the configurations produced by fiber reorientation, this is very important for aesthetic object, as from U.S. Patent No. 3, 485, the disclosure content of 706 can be recognized.

About the product of " water thorn " or " Hydroentangled " type, the existing long duration, can by making material blends, such as, by combining the multiple fiber web be made up of different types of fiber, the final performance of adjustment product, the fiber web (" spunbond " formula fiber web etc.) that different types of fiber such as natural fabric, artificial or synthetic fiber and even wherein fiber and the reinforcing material that can add non-woven structures are carried out in advance mix.

French Patent (FRP) FR-A-2 730 246 and 2 734 285, correspond respectively to U.S. Patent No. 5,718,022 and U.S. Patent No. 5,768,756, which depict such solution, make to utilize the mixture that water jet method successfully can process hydrophobic fibre or these fibers and other hydrophilic fibres and even the fiber web be made up of natural fabric completely.

In brief, according to the instruction content of these documents, this process relates to: process the basilar fibers net be made up of similar or inhomogeneity elementary fibril, compress and wetting this basilar fibers net, then, utilize at least one frame to act on the online uninterrupted high-pressure water jet of basilar fibers, make fiber mixed.

For this reason, on the endless loops foraminous support making basilar fibers net on-stream, forward is advanced, and is carried to by basilar fibers net on the surface of porose rotating cylinder drum, and the inside to porose rotating cylinder drum applies parital vacuum.Foraminous support advances with identical speed substantially with rotary drum, mechanical compression basilar fibers net between foraminous support and rotary drum.Immediately preceding the downstream of constricted zone, make cascade aligned fibers net, and make fiber web successively pass through foraminous support, compressed basilar fibers net and wherein remove the foraminous support drum of excess water with vacuum source.

Still on rotating cylinder drum, by the effect making the compressed and fiber web soaked stand at least one frame high-pressure water jet, make elementary fibril mixed continuously.Generally speaking, utilize the multiple water jets in succession establishing frame acting on fiber web identical faces or alternately act on fiber web two sides, realize combining, the water jet speed of the pressure in frame and discharge is different to next frame from a frame, and often increases progressively.

Importantly it should be noted that porose roller/drum can comprise the micropore of random distribution as recognized from FR 2 734 285.If needed, after initial combination process, after-treatment can be applied to the opposing face in fibrous nonwoven structures.

In the technique of producing water thorn or hydroentangled nonwoven product, be usually desirably on finished product and add pattern or mark, thus, product produces the Art Design of expectation.This pattern or mark are produced by secondary operation usually, and this secondary operation uses embossing or figuratum stack, independent of the shaping of nonwoven sheet with roll operation.These rollers involve great expense usually, and operate according to the rule compressed fiber web specific region, to produce pattern or the mark of requirement.But, use independent operation on nonwoven products, produce pattern or be marked with some deficiency.Such as, exigent initial investment is used for stack, the production running scale under this meeting limit production business economy institute enabled condition.Secondly, formed or the mark applying stage owing to setting up pattern, cause higher processing cost.3rd, the material content that finished product will have than requiring material content higher, to be maintained the thickness (caliper, thickness) of product after compressing at calendaring processes.Finally, owing to carrying out high pressure compressed during rolling, two-stage procedure will cause finished product bulk lower than required degree.Do not possess the protrusion of clear, appropriate formation with the prior art nonwoven products that these known pattern forming technologies are made, be therefore difficult to the pattern seeing expectation.In addition, the protrusion size of prior art embossed nonwoven product is unstable, and thus, based on institute's Application Areas, when being under pressure over time, become, the protrusion of nonwoven products can lose its three-dimensional structure.

U.S. Patent No. 5,098,764 and No.5,244,711 disclose use support member in the update methods of producing nonwoven web or nonwoven products.Support member has configural characteristic structure and array of apertures.In such a process, initial web is placed on configuration support member.Be loaded with fibroreticulate support member to pass through under the jet of high-pressure fluid (being generally water).Configuration based on support member constructs, and water jet impels fiber to be wound around mutually and tangles and form specific pattern.

For the structure of obtained nonwoven products, in support member, the pattern of configural characteristic and hole is very crucial.In addition, support member must have enough structural integrities and intensity, thus while fluid jet rearranges fiber and makes fiber tangle in its new arrangement, supports support fiber web, to provide stable fabric.Under the active force of fluid jet, support member can not have obvious distortion.In addition, support member must have the device for removing relatively a large amount of entangling fluid, to avoid affecting the fiber web " overflow (flooding) " effectively tangled.Usually, the drain aperture that support member comprises is sufficiently little, to maintain fibroreticulate integrality, and avoids fiber to pass the loss of forming face.In addition, should there is not the defect such as burr, hook thorn in support member, these defects can affect the separating property of entangled fiber nonwoven and support member substantially.Meanwhile, support member must to make on it process fibroreticulate fiber and can not be flushed away under the effect of fluid jet (that is, good fiber keeps and supportive).

It is the bonding realizing nonwoven composition fiber in one of subject matter that nonwoven production period exists, so that make nonwoven products possess correspond to institute consider application strength characteristics, meanwhile, maintain or give specific physical characteristic, such as bulk, feel, outward appearance etc.

During for its expection object, these performances of bulk, absorbability, intensity, flexibility and aesthetic appearance are really very important for many products.In order to manufacture the nonwoven products with these characteristics, often support configuration is become to make paper-contacting surface present topographical variations.

Should be understood that, these support members (fabric, belt, the collar) can take the form of endless loop, and, play a role in the mode of conveyer belt.Should be understood that further, non-woven production is the Continuous maching carried out with suitable fast speed.That is, in forming section, deposit on forming fabric/belt continuously by elementary fibril or fiber web, the entangled nonwoven fabric simultaneously just produced is transported to subsequent handling from support member continuously.

Summary of the invention

For the problem that discussed prior art patent/patent application above solves, the invention provides a kind of alternative solution.

The invention provides a kind of belt or the collar of improvement, act as and replace conventional belt or the collar, and, help to give institute on it and produce nonwoven products with the physical characteristic of expectation, such as bulk, outward appearance, texture, absorbability, intensity and feel.

Therefore, main purpose of the present invention is to provide a kind of water thorn or Hydroentangled support member, and such as belt or the collar, it has the penetrating space of desired pattern.

Another object is to provide a kind of belt or the collar can with configuration or texture, and configuration or texture are made by using manner known in the art, such as, sand papering, carve dig, embossing or etching.Above-mentioned and other object and advantage is realized by the present invention.The invention provides other advantages, such as but not limited to, fiber support and separation property (not residual) is improved compared with prior art Woven fabric, and, can catch the problem of elementary fibril owing to there is not yarn crossovers structure, it is more easy to clean.

If belt/collar has superficial makings, so more effective pattern/texture can be delivered to nonwoven, and, better physical property can also be obtained, such as bulk/absorbability.

The present invention relates to endless loops support member such as belt or the collar, for supporting in water thorn or Hydroentangled processing process and transporting natural fabric, artificial or synthetic fiber.Compared with calendering technology, cell structure of the present invention, belt or the collar show following non-limiting advantage: fabric collar relative cost is lower, in permanent plant, do not need very large input; In its entanglement process, realize patterning, do not need independent calendering processing; Lower material content can be obtained in the final product, this is because thickness does not reduce because of compression; Made final products have higher bulk, because it is not compressed at calendering stage.For non-woven roll-in product manufacturing person, the advantage of these processing process obtains following end product advantage further: more the water of low cost stings or Hydroentangled net, has required pattern, mark or texture; Manufacture the size/length of stroke owing to reducing specific products, can tailor-make product be manufactured; Can produce and have more high performance product, such as, the product with more high bulk imparts the feature of more high-absorbable, this for consumer application be very valuable.

In the exemplary embodiment, the belt of endless loops or the collar carry out spiral winding in the mode that edge edge is adjacent around two rollers by material bands and are formed.By suitable mode, band is firmly connected, to form endless loop for special-purpose with Len req and width.When the collar, band can be wound around around the surface of single roller or mandrel, and the diameter dimension of this roller or mandrel and transverse machine length are close to the rotary drum of this collar to be used.The material bands used is made generally in as industrial tapes material.Band particularly plastic strap material ordinary solution is interpreted as: for relatively thin plastics bandage that is article are fastening or that clip together.It is unexpected that discovery be, the characteristic that such plastic material has is suitable for the material bands forming belt of the present invention or the collar.

(plastics) definition difference between band and monofilament relates to size, shape and application.Band and monofilament are all processed into by extruding, and have identical basic step, i.e. extrusion step, uniaxial orientation step and winding step.Monofilament general size is less than band, and shape is generally round.Monofilament is widely used in multiple Application Areas, and such as fishing line and technical fabric, comprise Papermaking fabric.The size of band is usually much larger than monofilament, and substantially always wider along main shaft, and therefore, shape is for rectangle is for object needed for it.

In extruding technology field it is known that plastic strap is processed into by extruding.It is also known that this processing comprises the uniaxial orientation of extruded material.It is also known that have two kinds use uniaxial orientations substantially extrude processing.A kind of processing is extruded and orientation comparatively wide sheet material, is cut into single band.Another kind of processing is the single band extruding orientation.The second processing is very similar to the processing manufacturing monofilament, because the equipment of two kinds of processing is similar.

Use strip material to be better than monofilament part to be to manufacture the spiral winding number of times needed for fabric.Monofilament is regarded as the yarn being not more than 5mm at its greatest axis (axis) place usually.For paper machine clothing and other aforementioned applications uniaxial orientation filament size seldom at its greatest axis place more than 1.0mm.The strip material bandpass used is minimum is 10mm, and width can more than 100mm sometimes.Predictably, width also can be used up to the band of 1000mm.The supplier of strip material can be used to comprise such as Signode company.

Another advantage is the relation of thickness and stretch modulus.Such as, polyester of the prior art (polyethylene terephthalate, PET) film is about 3.5GPa in the stretch modulus of major axis (or MD, machine direction).The stretch modulus of PET strip material (or ribbon) material is in 10GPa to 12.5GPa scope.In order to obtain identical modulus with film, structure needs thicker and makes thickness reach 3 to 3.6 times.

Therefore, according to an exemplary embodiment, fabric of the present invention, belt or the collar banded thing of these spiral windings is formed as single or multiple lift structure.Fabric, belt or the collar can have smooth, smooth end face and bottom surface.Can also manner known in the art be used, paper polishing, carve dig, embossing or etching, make belt or the collar have the texture of certain form.Belt or the collar can be to air and/or water impermeable.Some mechanical systems or hot-working (laser) mode can also be used to bore a hole to belt or the collar, make it can through air and/or water.

In a further exemplary embodiment, ribbon is formed as having interlocking shape.Belt or the collar are wound around by these interlocking helix and are formed, and the situation only parallel and/or vertically adjacent compared to the edge of adjacent belts band, such belt or the collar can have higher globality.This belt or the collar also can not through air and/or water, or be bored a hole to make it can pass through air and/or water to it.

Although the individual layer band of the previous embodiment banded thing that is spiral winding, more preferably, use the bar with multiple geometry to bring to be formed the belt with two-layer or more layer or the collar.Therefore, according to an exemplary embodiment, belt or the collar can have two-layer or more layer, and wherein, band can be formed as two-layer or more layer mechanical system interlocking, or is connected together by other modes well known by persons skilled in the art.Equally, structure can not through air and/or water, or can carry out boring a hole to make it can pass through air and/or water.

Another exemplary embodiment is the multilayer structure making using " welding band " concept to be formed, and is somebody's turn to do " welding band " for improving the globality of belt or the collar further.This structure can not through air and/or water, or can carry out boring a hole to make it can pass through air and/or water.

Detailed description of the invention

Below, with reference to the accompanying drawing that the preferred embodiment of the present invention is shown, the present invention is described more fully.But the present invention may be embodied as multiple multi-form, and should not be inferred as and be only confined to embodiment given in this article.In addition, these illustrative embodiments are provided to be clear complete in order to make to disclose herein, and, those skilled in the art can be made to understand scope of the present invention completely.

The invention provides a kind of continuous support member of such as endless loops belt, be suitable for using in the device such as shown in Figure 15.Non-woven support member plays the effect replacing conventional woven support member, and gives institute on it and produce nonwoven products with the texture of expectation, feel and bulk.Support member of the present invention can reduce the manufacturing time and cost that manufacture nonwoven.

Figure 15 illustrates the device using support member according to the present invention for continuous seepage supatex fabric.Figure 15 shown device comprises in fact as the conveyer belt 80 according to configuration support member of the present invention.Belt moves in the counterclockwise direction continuously around the roller that a pair point is opened, as known in the art.Being arranged in above belt 80 is Fluid injection manifold 79, and Fluid injection manifold 79 connects multiple ozzle (orifice) row or ozzle group 81.The each group of ozzle with a line or the superfine diameter of multirow, each nozzle diameter is about 0.007 inch, and per inch has 30 this ozzles.Supply water to ozzle group 81 under a predetermined, and water is sprayed from ozzle with superfine, roughly cylindric, the water line of non-diverging or the form of water jet.Manifold is equipped with pressure gauge 88 and control valve 87, for regulating the fluid pressure of each ozzle row or ozzle group.Be arranged in each ozzle row or ozzle group below be suction box 82, for removing excess water, and keep this region to avoid excessive overflow.The fiber web 83 that will be formed as nonwoven products delivers to configuration support member conveyer belt of the present invention.By suitable nozzle 84, water is sprayed onto on fiber web, to make the fiber web 83 entered prewet, and, when fiber is below Fluid injection manifold, help to control fiber.Water suction slit 85 is arranged in below this (operating) water nozzle to remove excess water.Fiber web passes through in the counterclockwise direction under Fluid injection manifold.The operating pressure of any appointment ozzle group 81 can set independent of the operating pressure of other ozzle groups 81 any.But the ozzle group 81 usually closest to nozzle 84 operates with relatively low pressure such as 100psi.This contributes to the fiber web entered to be placed in support surface.Along with fiber web is in the counter clockwise direction process of Figure 15, the operating pressure of ozzle group 81 is usually made to increase.Without the need to making each follow-up ozzle group 81 with the pressure operation higher than its clockwise direction adjacent nozzles group.Such as, two or more adjacent ozzle groups 81 can operate with uniform pressure, and next (counterclockwise) follow-up ozzle group 81 thereafter can operate with different pressures.The most usually, the operating pressure taking off fibroreticulate conveyer belt end initially sends into the operating pressure at conveyer belt place higher than fiber web.Although six ozzle groups 81 shown in Figure 15, this quantity is not key factor, but depends on fibrous web weight, speed, the pressure used, the line number respectively organizing mesopore etc.After have passed between Fluid injection manifold and aspiration manifold, make the supatex fabric process above additional water suction slit 86 just formed, to remove excess water.Distance end face from the bottom surface of ozzle group 81 to fiber web 83 is usually the scope of about 0.5 inch to about 2.0 inches; Be preferably the scope of about 0.75 inch to about 1.0 inches.Obviously, fiber web can not and manifold interval too near and fiber web is contacted with manifold.On the other hand, if the distance between the bottom surface of ozzle and fibroreticulate end face is too large, liquid stream is by off-energy, and thus working (machining) efficiency reduces.

Figure 16 schematically shows and uses support member of the present invention to produce the preferred embodiment of supatex fabric.In this device, configuration support member is rotating bulging cover 91.Rotary drum below drum cover 91 rotates in the counterclockwise direction.The outer surface of drum cover 91 comprises the configuration support structure of expectation.A part of periphery around rotary drum is furnished with manifold 89, and manifold 89 connects multiple ozzle bar 92, and ozzle bar 92 is for applying water or other fluids to the fiber web 93 being arranged in bent plate outer surface.Each ozzle bar can comprise superfine diametric hole or the hole of mentioning type before a line or multirow this paper.Usually, the nominal diameter of hole is such as about 0.005 inch to 0.01 inch.Obviously, in order to be adapted to needs, other sizes, shape and orientation can be adopted.Equally, as required, per inch can have such as nearly 50 or 60 holes or more.Guide water or other fluids capable by ozzle.Generally speaking, as mentioned above, the pressure of each ozzle group increases from first group (fiber web passes through from below it) to last group usually.Pressure is controlled by suitable control valve 97, and is monitored by pressure gauge 98.Rotary drum is connected with tank 94, can aspiration vacuum on tank 94, to help removing moisture and to keep this region to avoid overflow.In operation, before water spray manifold 89, fiber web 93 is placed on the end face of configuration support member, as shown in figure 16.Fiber web through the below of ozzle bar, and is formed as nonwoven products.Then, the nonwoven formed is through the section 95 of this device 95, and this section place does not have ozzle bar, but is continuously applied vacuum.Fabric after dehydration is taken off from rotary drum, and makes it advance to walk around a series of drying box 96, to make fabric drying.

The following describes the structure of support member, belt or the collar, support member can have the pattern in penetrating space.Among various features, penetrating space can comprise such geometric properties, when such as support member, belt or the collar are produced nonwoven products or net, and the configuration that this geometric properties makes nonwoven products or netting gear be improved and bulk.Other advantages of support member of the present invention comprise: easily make fiber web be separated, the antifouling property of improvement, and the residual fiber left lowered.Another advantage is that support member of the present invention avoids the next restriction of conventional loom belt and requirement, and this is because penetrating space can be placed in any desired site or pattern.Support member also can have texture on a surface or two surfaces, and texture is made by using prior art known way, such as, sand papering, carve dig, embossing or etching.

Should be appreciated that term " penetrating space (through void) " is the synonym of " open-work (throughhole) ", and represent and penetrate the opening of support member as belt or the collar completely.Here the support member of indication to include but are not limited to: in nonwoven production process the concrete technical fabric used, such as belt or conveyer belt and the collar or tubular belt.As mentioned before, although use term fabric and textile structure to describe preferred embodiment, fabric, belt, conveyer belt, the collar, support member and textile structure can exchange and make for describing structure of the present invention.

Fig. 1 is the axonometric drawing of technical fabric of the present invention, belt or the collar 10.Fabric, belt or the collar 10 has inner surface 12 and outer surface 14, and abuts against and interconnective ring and being formed by polymeric material band 16 spiral winding being become multiple, and polymeric material band 16 is industrial tapes material such as.To construct the spiral way of fabric, belt or the collar 10, around the length of fabric, belt or the collar 10, material bands 16 is roughly longitudinally carrying out spiral.

Fig. 2 illustrates the illustrative methods that can manufacture fabric, belt or the collar 10.Device 20 comprises the first working roll 22 and the second working roll 24, and each working roll can around its fore-aft axis.First working roll 22 and the second working roll 24 parallel to each other, and spaced apart certain distance, this distance determines the overall length that manufactured fabric, belt or the collar 10 is measured at vertical wraparound.In the first working roll 22 side, be provided with supply spool (not shown), this supply spool is installed as to enclose and is rotated about axis, and removably parallels layout with working roll 22 and 24.Supply spool holds width such as the material bands 16 being more than or equal to 10mm reels aliment.Such as, first supply spool is positioned at the left hand end of such as the first working roll 12, then at a predetermined velocity to the right or the continuous dislocation in other sides.

When starting to manufacture fabric, belt or the collar 10, the initiating terminal of polymeric material band 16 extends towards the second working roll 24 from the first working roll 22 with tension, walks around the second working roll 24, then gets back to the first working roll 22, forms first lap closed helical 26.In order to closed first lap closed helical 26, the initiating terminal of material bands 16 is connected to the end of its first lap at point 28 place.As mentioned below, the adjacent ring of spiral winding material bands 16 is connected to each other by machinery and/or adhesive means.

Therefore, by making the first working roll 22 and the second working roll 24 common direction shown in Fig. 2 arrow rotate, material bands 16 being sent into the first working roll 22 simultaneously, making follow-up circle closed helical 26.Meanwhile, be suitable for by such as machinery and/or adhesive or other mode manufacturing additional turns closed helical 26, the material bands 16 be newly wrapped on the first working roll 22 be connected to continuously the material bands be placed on the first working roll 22 and the second working roll 24.

Continue to carry out this processing, until closed helical 26 has required width along the first working roll 22 or the second working roll 24 axial measurement.Now, cut the material bands 16 be not yet wound on the first working roll 22 and the second working roll 24, and made closed helical 26 is taken off, to provide fabric of the present invention, belt or the collar 10 from the first working roll 22 and the second working roll 24.

Although this document describes the configuration of two rollers, it is readily appreciated by a person skilled in the art that can around the surface wrap band of single roller or mandrel, to form fabric of the present invention, belt or the collar.Based on the required size of fabric to be manufactured, belt or the collar, the suitable size of roller or mandrel can be selected.

For manufacturing the nonwoven and/or technical fabric or belt or the collar with different longitudinal size and lateral dimension, the present invention is very general and suitable for the manufacture of the method for fabric, belt or the collar 10.That is, by adopting the present invention, producer is without the need to again for the nonwoven maker manufacture of specifying has the Woven fabric of suitable length and width.The substitute is, first working roll 22 and the second working roll 24 only need be separated with appropriate intervals by producer, with determine fabric, belt or the collar 10 close to length, and material bands 16 is wrapped on the first working roll 22 and the second working roll 24, until closed helical 26 reaches close to required width.

In addition, because fabric, belt or the collar 10 is not Woven fabric, but made by polymeric material band 16 spiral winding, the outer surface 12 of fabric, belt or the collar 10 can be level and smooth and continuous print, and there is not the tubercle making Woven fabric not possess complete smooth surface.But fabric of the present invention, belt or the collar nonwoven products that can have for it is processed provides the configuration of enhancing and the geometric properties of bulk.Other advantages of support member of the present invention comprise: easily make net be separated, the antifouling property of improvement, and reduce residual fiber left.Another advantage is that support member of the present invention avoids the restriction and requirement that conventional loom brings, and this is because penetrating space can be placed in any desired position or pattern.Fabric, belt or the collar also can have texture on a surface or two surfaces, and texture is made by using prior art known way, such as, sand papering, carve dig, embossing or etching.Selectively, fabric, belt or the collar can be level and smooth on a surface or two surfaces.

The sectional view of Fig. 3 (a) to Fig. 3 (i) for getting at width, illustrates the different materials band embodiment for the manufacture of fabric of the present invention, belt or the collar.The upper surface that each embodiment comprises and lower surface can be parallel to each other for smooth (plane), or, certain profile being applicable to application-specific can be had.With reference to Fig. 3 (a), according to one embodiment of present invention, material bands 16 has upper surface 15, lower surface 17, first planar side 18 and the second planar side 19.Upper surface 15 and lower surface 17 can be smooth (plane) and parallel to each other, and, first planar side 18 can tilt in parallel direction with the second planar side 19, makes the second planar side 19 of first this material bands of planar side 18 tight abutment next-door neighbour ring of each spiral winding material bands 16.By such as adhesive (such as can be heat sensitive adhesive, cold curing (RTC) adhesive or hot-melt adhesive) or other modes be applicable to, respective the first planar side 18 of each ring of material bands 16 and adjacent ring and the second planar side 19 are bonded to each other, thus each ring is combined with adjacent ring.

In Fig. 3 (b), the cross-sectional structure of material bands 16 can allow mechanical interlocked, adjacent materials band 16 to be combined into fabric, belt or the collar that spiral way is formed.Adjacent material bands 16 can have identical or different size and/or profile, but has locking position separately, as shown in Fig. 3 (b).Other embodiments of mechanical interlock are shown in Fig. 3 (c) in Fig. 3 (g), the cross section of single material bands 16 shown in it.In every case, a side of material bands 16 can be designed to mechanical interlocked with the another side of adjacent materials band 16 or be connected.Such as, see the embodiment shown by Fig. 3 (g), material bands 16 can have upper surface 42, lower surface 44, the respective grooves 48 that is positioned at the tongue 46 on a side and is positioned on another side.Tongue 46 can have the size corresponding to groove 48 size, thus the tongue 46 on each spiral winding ring of band 16 coordinates in the groove 48 of its next-door neighbour's ring.By being fixed in groove 48 by tongue 46, each ring of material bands 16 is connected to its adjacent ring.Based on application, upper surface 42 and lower surface 44 can be smooth (plane) and parallel to each other, or are non-planar and uneven, or, can be even the circle protruded or be recessed in its width direction, as shown in Fig. 3 (f).Similarly, each side of band can be formed as cylindrical bump or the recess with same curvature radius.

Fig. 3 (h) illustrates another embodiment of the present invention.

Except the above-mentioned material bands extruded that makes has except relative hemispherical or profile, other shapes multiple can be extruded or rectangle extrudate is processed into other shapes multiple, to have the pairing edge of band horizontal bar (rails), this can be convenient to be combined by the mode of machinery and/or adhesive.Fig. 3 (i) illustrates a this structure according to an illustrative embodiment of the invention.Selectively, material bands can not need to match or the left surface that combines and right flank.Such as, as shown in Fig. 4 (a), the cross section of material bands 16 surface or top side face can have interlocking grooves thereon, or material bands 16 can have interlocking grooves, as shown in Fig. 4 (b) at its lower surface or bottom side.

By way of example, Fig. 4 (c) illustrates that location is to carry out material bands shown in Fig. 4 (a) of interlocking and Fig. 4 (b).Such as, the arrow in Fig. 4 (c) indicates each material bands 16 will the direction of movement, to merge with trench intersection, two bands is interlocked.Fig. 4 (d) illustrates interlocked with one another or after combining two material bands 16.Although only illustrate two material bands matched in exemplary embodiment, it is to be understood that finished textile product, belt or the collar are formed by several material bands interlocked together.Obviously, if make material bands interlock in spiral winding processing, the material piece of endless loop form can be formed.What should also be clear that is, although illustrate mechanical interlocked mode, but also can be improved the intensity of interlocking by the mode of such as heat bonding, particularly by being such as known as the selective adhering technique (see www.clearweld.com) of the commercial process of " Clearweld ".

Fig. 5 (a) illustrates the sectional view at its top surface side and bottom surface side fluted material bands 16 of tool.Fig. 5 (b) illustrates how two material bands 16 with shape of cross section shown in Fig. 5 (a) interlock.Interlocking structure obtains being positioned at the groove on the end face of end product and bottom surface.

See Fig. 5 (c) illustrated embodiment, Fig. 5 (c) illustrates the interlocking of bi-material band 16 shown in Fig. 5 (a) and Fig. 4 (b).Articles of sheet material obtained like this has groove on bottom surface, and has smooth end face.Similarly, also structure can be formed as at end face, there is groove, and there is smooth bottom surface.

Another exemplary embodiment is that this lock mode is formed because of its Machine Design and more firmly interlocks by having fabric, belt or the collar that handle-shaped interlocks or " initiatively (positive) " material bands 16 of locking is formed.The theory that such design adopts " initiatively " to interlock, that is, pin member and the receiving member for this pin member have machinery obstruction, and this needs sizable power to make ribbon combine or to make it separated from one another.Such as, Fig. 6 (a) illustrates the handle-shaped interlocking feature in single strip material band 16.Fig. 6 (b) illustrates, is being designed in the opposed formations interlocked with structure Fig. 6 (a) Suo Shi, the handle-shaped interlock feature of single strip material band 16.Fig. 6 (c) illustrates Fig. 6 (a) and the shown single strip material band of Fig. 6 (b) of locating for interlocking.Here it is to be understood that the staggered positions of top band thing and bottom ribbon is to hold the other material bands 16 with opposed formations.Finally, Fig. 6 (d) illustrates that these same strap form interlocking structure after being press-fitted into together.Can several strip material band being similar to this structure be interlocked together, to form finished textile product, belt or the collar.

Another exemplary embodiment for by its top surface side and bottom surface side all fabric, belt or collars of being formed of the fluted material bands 16 of tool, such as, as shown in Fig. 7 (a).These two kinds of strip material bands 16 are designed to combine to form active interlock, as shown in Fig. 7 (b).It is to be understood that end face and bottom surface all keep groove on respective surface.Equally, see Fig. 7 (a) and Fig. 7 (b), those of ordinary skill in the art's easy understand, can by three band combinations to form multilayer structure making, or, if only use two bands, the groove in the band of top side can have different trench profile at top surface side and bottom surface side.Similarly, the groove in the band of bottom side can have identical or different trench profile at either side.As mentioned before, although embodiment described herein is used for the banded thing of individual layer spiral winding or band, advantageously, use the band with different configuration to be formed to have the band of two-layer or more layer.Therefore, according to an exemplary embodiment, belt can have two-layer or more layer, and wherein, band can be formed as making two-layer or more layer mechanical interlocked.Each layer can be helically wound around opposite direction, or, in machine direction, there is certain angle, to provide additional intensity.

For example, the interlocking structure that Fig. 7 (c) illustrates has with groove bottom surface and flat top, and the interlocking structure that Fig. 7 (d) illustrates has planar bottom surface and with groove end face.

It is readily appreciated by a person skilled in the art that and various shape can be adopted to form above-mentioned active interlock.Such as, aforementioned several embodiment concentrates on circular handle-shaped projection and circular collecting part.But, also can use that other shapes are such as trapezoidal realizes identical effect.The active interlock embodiment with this shape is illustrated in Fig. 8 (a).Selectively, various shape can be mixed to realize active interlock.The embodiment of mixing shape is illustrated in Fig. 8 (b) and Fig. 8 (c).

As described in above-described embodiment, formed mechanical interlocked by this way between adjacent materials band, more easily manufacture spiral wound base fabric or structure, because if do not provide this locking, material bands adjacent in spiral wound fabrics manufacture process may depart from and be separated.Mechanical interlocked by adjoining spiral, can prevent from departing between adjoining spiral and being separated.In addition, owing to can also form thermal welding in the mechanical caging region of fabric, bonding strength is without the need to only depending on the intensity of mechanical caging.According to one embodiment of present invention, this can be realized by following manner: before male feature/female member being locked together, place near-infrared or infrared or laser light absorbing dye, then mechanical caging position is made to be exposed to near-infrared or infrared light supply or lasing light emitter, cause mechanical caging position that thermal welding occurs, and without the need to making the material generation melting outside mechanical caging region.

Material bands described by above-described embodiment can be extruded with polymer resin material known to persons of ordinary skill in the art and form, such as, and polyester, polyamide, polyurethane, polypropylene, polyether-ether-ketone resin etc.Because industrial tapes is uniaxial orientation, namely, its stretch modulus is at least twice of biaxial orientation material (film), and can up to ten times of extruded material (profiled member) modulus, it is favourable that industrial tapes is used as base material, even so, the material that other are applicable to can also be used.That is, the structure desired thickness that uniaxial orientation material obtains is less than biaxial orientation material (film), is one half thickness, and is less than extruded material (profiled member) thickness, for its 1/10th.This feature is shown in Figure 9, and result shown in it is, for the result of the fixed width of setting and parts of specific power and strain.Equation used in this design problem is the relation between stress and strain, is shown below:

In this chart, power (or load) keeps constant together with width and strain.This equation illustrates, desired thickness and material modulus are inversely proportional to.This equation represents the problem about DIMENSIONAL STABILITY design nonwoven maker, that is, load is known, and maximum strain is known, and machine-wide is fixed.Result is expressed as this part based on the final thickness needed for adopted material modulus.Obviously, the uniaxial material of such as band or ribbon is obviously better than film and forming polymer, as shown in Figure 9.But support member of the present invention, belt or the collar are not limited to the band of single shaft or biaxial orientation, because any one or two kinds of that can use in above-mentioned orientation when putting into practice of the present invention all adopt.

According to an embodiment, the material bands described in foregoing embodiments or ribbon of material can comprise reinforcement material, to improve integrally-built mechanical strength.Such as, reinforcement material can be fiber, yarn, monofilament or multifilament yarn, along the length of strip material, in the machine direction orientation of fabric, the collar or belt.By extruding processing or pultrusion processing, fiber or yarn can be extruded or pultrusion together with forming the material of material bands or ribbon of material, add this reinforcement material.Reinforcement material can embed in strip material completely, or be partially submerged into strip material one or two on the surface, or either way to have.Reinforcing fibre or reinforcement yarn can be formed by high modulus material, and such as aromatic polyamides, includes but not limited to with and extra intensity, stretch modulus, tear resistance and/or resistance to fracture, ABRASION RESISTANCE and/or chemically-resistant degradation property can be provided for material bands or ribbon of material.Put it briefly, reinforcing fibre or reinforcement yarn can be made up of thermoplastic polymer and/or thermosetting polymer.The non-limiting example of suitable fibrous material comprises glass, carbon, polyester, polyethylene and metal (such as steel).According to another embodiment, the melt temperature of described reinforcing fibre or reinforcement yarn can higher than the melt temperature of material bands or ribbon of material, or vice versa.

Band is provided as usually has continuous length, and product has rectangular cross section.Band is tough and tensile, general, usually untreated polyester band, and have excellent operational processes characteristic, this makes it be suitable for many commercial Application.As mentioned before, it has excellent mechanical strength and DIMENSIONAL STABILITY, and can not increase with service time and become fragile under normal operation.Band has good tolerance to moisture and most of chemicals, and can bear-70 DEG C to 150 DEG C or higher temperature.Available strip material typical cross-section dimension is in the present invention, such as, thickness is 0.30mm (or larger), and width is 10mm (or larger).When band can be spiral winding, for the adjacent turn in band without interlock (for remaining to together), need to carry out welding or connecting by other modes.In this case, laser weld or ultrasonic bonding can be used, adjacent ribbon or material bands to be fixed or welded together, thus improve transverse machine (" CD ") performance, such as intensity, and the risk lowering that separation occurs adjacent materials band.

Although find that single shaft band has maximum machine direction modulus, other performances outside modulus are also very important.Such as, if machine direction modulus is for too high strip material, then the resistance to fracture of finished product structure body and flex fatigue may be unacceptable.Alternatively, the transverse machine performance of finished product structure body is also very important.Such as, when relating to polyethylene terephthalate (PET) material and have the material bands of same thickness, non-oriented band can have the machine direction modulus of typical approximately 3GPa and the intensity of about 50MPa.On the other hand, the band of biaxial orientation can have the machine direction modulus of about 4.7GPa and the intensity of about 170MPa.Having been found that by changing the processing process of single shaft band, making machine direction modulus can between 6GPa to 10GPa, and intensity can be equal to or greater than 250MPa, can obtain the band of transverse machine intensity close to about 100MPa like this.In addition, this material can more broken (fracture), that is, can not break when repeatedly bending, and the processing process of this material be better when being connected together by band.When maker is carried out expection application, the combination between band still can resistant to separation.

According to one embodiment of present invention, a kind of by adjacent ribbons, the method remained to together is, when being welded mutually with edge at the edge of adjacent ribbons by ultrasonic wave mode, provides lateral pressure, contacts with each other to be remained at edge.Such as, a band (being preferably wound in the band of spiral) can remain down against backing roll by a part for welder, meanwhile, another part of device is pushed another band (being preferably unwound band) to this and is remained downward band.Such as, the welding of this kind of edge edge is illustrated in Figure 11 (a).

Adopt ultrasonic wave intermittently to weld (ultrasonic gap welding) to obtain firmly combining especially.On the contrary, the combination that the ultrasonic bonding (it is also for conventional ultrasonic bonding) carried out with temporal mode or energy model obtains can be described as crisp (easy fracture).Therefore, such conclusion can be obtained, intermittently weld formed combination by ultrasonic wave and be better than welding formed combination by conventional ultrasound.

According to one embodiment of the invention, another kind of by adjacent ribbons the illustrative methods remained to together be adhesive 30 is put on adjacent ribbons 16,16 end 34,36 and be connected to together, as shown in Figure 10 (a) to Figure 10 (d).Packing material 32 it is to be understood that can be used to the gap of filling band and not contacting with each other or position.

According to one embodiment of the invention, the method that adjacent materials band or functional band remain to together is use " the welding band " that be made up of the base material identical with material bands by another kind.Such as, this welding band is illustrated in Figure 11 (b), as the thin material appeared at above and below material bands.In this arrangement, welding band is that the material bands that will weld provides a kind of material, and the edge edge that formed structure is not relied on shown by Figure 11 (a) welds.Use the method for welding band, the welding of edge edge can be obtained; But this is not required, neither be preferred.Use the method for welding band, can form " sandwich-type " or stacked-up type structure, the horizontal surface of material bands welds mutually with the horizontal surface welding band, as shown in Figure 11 (b).It is to be understood that weld band to be also positioned at below material bands without the need to being both positioned at above material bands, welding band only can be positioned at the top of material bands or only be positioned at below it.According to an aspect, welding band can also be the mid portion of sandwich type structure body, and now material bands is positioned at top and/or the below of welding band.In addition, welding band is depicted as thinner than material bands, and be depicted as and have the width identical with material bands, this is only the use illustrated.Welding band can suitably be narrower than or wider than material bands, and, its thickness had can with the identical of material bands or thicker even.Welding band can also be another sheet material band, instead of is only the object and the special material made of welding band.Welding band can also be applied with adhesive on one of its surface, carries out welding operation with auxiliary to be held in place by welding band.But, if use such adhesive, preferably adhesive local is put on welding band instead of whole surface, because, when carrying out ultrasonic bonding or laser weld, local applies to promote that the material bands of analog material (such as, polyester and polyester) firmly welds with welding between band.

If welding band is made by not having the extruded polymer of orientation, then preferably, welding band is much thinner than material bands, because non-oriented welding band of extruding keeps the ability of finished product structure DIMENSIONAL STABILITY poor, as mentioned before.But if welding band is made up of the polymer through orientation, preferably, the welding band combined with material bands is thin as far as possible.As mentioned before, welding band can be another sheet material band.But, in this case, preferably, the thickness of each material is selected, the gross thickness of interlayer body or stack can be minimized.Equally as mentioned before, welding band can be coated with adhesive, is remained to together by structure in further processing process.According to an aspect, the welding band with adhesive may be used for such as producing the structure that directly enters perforation step (can be laser drill) and need not carry out ultrasonic wave combination, makes laser drill or laser beam perforation produce the means of spot welds that sandwich structural body can be remained to together.

According to one embodiment of present invention, the mode that adjacent materials band remains to together is by another kind, uses laser welding technology to weld adjacent band.
