Traditional flocked fabric 10 of embossing is not showed with the sectional view among Fig. 1 a and Fig. 1 b as yet.The substrate layer 12 that this fabric is covered by the tapetum of forming by adhesive layer 14, by numerous down fibers 18 that stick on the adhesive layer 14 successively 16 is formed.Shown in Fig. 1 b, with regard to as yet not with regard to the velour of embossing, villus fiber 18 is orientation so normally, and is promptly parallel to each other in essence and embed the surface of adhesive layer 14 wherein in essence perpendicular to fine hair.
As shown in the figure, the woven fabric that formed by warp thread 21 and weft yarn 23 of substrate 12 is formed.Substrate 12 can be made by various woven materials with natural fabric and/or synthetic fiber or their combination merging.In a specific embodiment, substrate can be made up of the mixture of polymer-cotton (poly-cotton) of 65%/35%, and weight is approximately 3.0 to 3.5 ounce per square yard.Although in the embodiment that illustrates, woven fabric is expressed as substrate, but should be appreciated that substrate 12 can be the material that is fit to any kind of tapetum flocking in other embodiment, the plastic sheet of fabric, porous or the atresia of for example various woven fabric, bondedfibre fabric, braiding and paper and similar thing, this is conspicuous for the people who is familiar with this technology.
The tapetum 16 that comprises villus fiber 18 can be made up of various natural fabrics and/or synthetic fiber according to the specific feature of the expection of velour 10 equally.In preferred embodiments, tapetum 16 is made up of the villus fiber 18 that forms with synthetic polymeric material.In a more preferred embodiment, villus fiber 18 comprises nylon fiber.Being used for the fiber 18 of flocking can be natural aspect color or dyeing, depend on specific application, and tapetum 16 can be with being that villus fiber 18 with a kind of color is made entirely, therefore form monochromatic matte 16, perhaps make, therefore form coloury matte 16 with multiple villus fiber 18 with different colours.With regard among the present invention decalcomania being moved on to regard to the purposes that velour is, preferably use villus fiber or undyed villus fiber with a kind of color.
In order to produce the velour of feature with the needs that conform with specific application, the length of villus fiber 18, fiber number and villus fiber can change in relatively broader scope and select in the number density on the adhesive layer 14, and this is tangible for the people who is familiar with this technology.In a typical embodiment, villus fiber 18 can have the total length between (more preferably between about 0.04 inch and about 0.065 inch) between about 0.025 inch and 0.08 inch, fiber number between about 0.45 denier and about 3.5 deniers, and between about 1.0 and about 3.5 ounce per square yard fabrics between cashmere density.
As what below will discuss in more detail, tapetum 16 can place on the substrate with various technical traditional methods, comprising use such as own together license to Laird at this by quoting the United States Patent (USP) of incorporating into the 5th as proof, the sort of (the roller rod) described in more detail in 108, No. 777 patted flocking type flocking apparatus or electrostatic spinning equipment.Decalcomania also can be transferred on the flocked fabric by various traditional technology, obviously includes but not limited to serigraphy, transfer paper printing, Freehandhand-drawing, spray printing or the like for the people who is familiar with this technology.
Fig. 2 illustrates as the flocked fabric 20 that has utilized according to the representative of the fabric of air-flow raging system provided by the invention and the embossing of method air-flow.But the tapetum 16 that comprises the embossed surface of fabric 20 comprises numerous air-flow embossing position 22.Air-flow embossing position 22 be with lodging or otherwise the villus fiber of reorientation be characteristic.Adjoin and what be independent of embossing position 22 be that fabric face vertically extends out from adhesive layer 14 in essence with villus fiber 18 is the not embossing part 24 of characteristic.
Fabric by the part of air-flow embossing and not embossed part in being oriented in the sectional view shown in Fig. 2 b of villus fiber see clearlyer.Fig. 2 c illustrates the sort of similar embossing velour of producing according to traditional air-flow raging system of prior art and method 30.There is the contrast of air-flow embossed fabrics 20 of the present invention and traditional air-flow embossed fabrics 30 to illustrate several important differences.At first, characteristic size with the meticulousst minimum embossing position of air-flow embossed fabrics of the present invention is far smaller than the embossing position of the characteristic size that can realize with traditional system and method.For example, the embossing position 26 that comprises minimum according to embossed fabrics 20 provided by the invention with small-feature-size 28.Under the contrast, the corresponding embossing position 36 that produces with traditional system has much bigger characteristic size 38 usually.The employed phrase of this paper " characteristic size at embossing position " refers to this position and does not stride across the cross sectional dimensions of described position to the minimum of measuring at second edge 29 in another not embossed zone of this position opposite side in first edge 27 of embossed part from tapetum 16.
Can also see when comparing with the fabric of producing according to traditional air-flow embossing technology 30 in the zone 25 of the reorientation of tapetum 16 and not embossed contiguous zone 24 by the bigger embossing position among comparison diagram 2b and the 2c and to exist sizable visual contrast level between the fiber according to fabric 20 provided by the invention.Specifically, in fabric 20 of the present invention, the fiber of reorientation lodges on substrate more fully in the reorientation part 25.In addition, can be very little the upright in essence fiber distance 31 of separating in the fiber of lodging in the reorientation part 25 and the not embossing part 24 and can be far smaller than utilize the fabric 30 that traditional air-flow embossing technology can realize usually equivalence apart from 37.Therefore, use the air-flow embossed fabrics of producing according to air-flow raging system of the present invention and method can have unprecedented exquisite details and also the embossing part of velour and not embossed portion can have unprecedented contour sharpness and visual contrast between dividing, thereby that can't realize with the air-flow raging system and embossed pattern and visual effect that have only the more expensive cylinder embossing of utilization technology to produce before obtaining.
Fig. 3 illustrates according to the present invention and is used for forming method for optimizing according to the matte flocked fabric of embossing of the present invention.Except the improvement of the present invention to air-flow raging system 109 of following detailed introduction, embossed fabrics production system 100 shown in Figure 3 can be traditional in essence and can adopt for the well-known method of the people who is familiar with this technology and operate at design aspect.This method and system that is used for the air-flow embossing is widely used in the prior art, and provides more detailed description in the document such as No. the 3rd, 916,823, United States Patent (USP) that licenses to Halloran and so on.The process that is used for producing the matte embossed fabrics that is similar to the fabric of showing with Fig. 2 a the front 20 can be proceeded in the introduction below.Substrate 12 on the reel 102 can be transported to winding drum 120 by arrow 105 indicated directions from substrate reel 102 by the traditional motor transmission mechanism that controllably drives a reel (being winding drum 120) or two reels under the state of tightening.Fabric can be directed to and support along machining path by a series of back-up rollers 104.Transmit in other embodiment of fabric in the rotation that replaces or do not comprise the winding drum/substrate reel that drives by motor, fabric can move by this system by traditional induction system (for example conveyer belt or board-like conveyer).Then, by traditional adhesive coating machine 106 (for example, cylinder coating machine, curtain stream coating machine, scraper, printing process and other) adhesive layer is coated onto on the substrate 12.Usually, adhesive is coated onto on the substrate with scraper, although other method such as printing, spraying and serigraphy also can be used.In preferred embodiments, adhesive layer is coated onto on the entire upper surface of substrate 12.
Then, the substrate 12 that scribbles adhesive layer is delivered to the flocking cabin 108 that comprises fine hair dispenser 110.Produce in traditional flocking cabin 108 of flocked fabric being used for, the cashmere-planted layer that is formed by multifarious fiber 18 is imposed on the adhesive.According to tradition and as described in hereinafter, this deposition can adhere to that traditional (roller rod) on the adhesive layer patted flocking technology or static flocking technology be finished fully by the end that makes villus fiber 18.In preferred embodiments, villus fiber 18 is vertical in essence and the adhesive layer orientation.In some preferred embodiments, flocking cabin 108 can comprise such as own together license to Laird and at this by quoting the United States Patent (USP) of incorporating into the 5th as proof, the sort of electrostatic flocking apparatus of describing in 108, No. 777 and so on documents that exchanges with frequency-changing AC electrostatic field of optimizing flocked fiber characteristic and working (machining) efficiency.
Apply after the tapetum, the substrate 111 of flocking is sent to and comprises compressed ir spray gun (below at length show and describe) and below air-flow embossing cylinder 112 that compressed air supply line 114 fluids are communicated with.As what be described in more detail below, above generally including, air-flow embossing cylinder 112 has the cylindrical screen or the template of eyelet and solid area.In addition, as what be described in more detail below, be compressed cylindrical screen or hole template on or the eyelet of air gun guiding by embossing cylinder 112 from the compressed air of air supply pipeline 114 and in the tapetum scope of fabric, form the embossing position.Embossed pattern is because the flow of pore in the cylindrical screen of air communication overvoltage style face 112 or the template scope causes fiber 18 deflections in the tapetum forms.Bump villus fiber 18 during the hole of air-flow on the template that flows through embossing cylinder 112 forces them to be orientated by the direction of the pore size regulation of partly being passed through by air velocity, airflow direction and template overdraught.In other words, those tapetum that passes through under the hole in cylindrical shape template scope parts will change orientation, press in the embossed pattern and to form depression, but those the solid area of template below by the part reorientation that will not submit to substantial air-flow or make the villus fiber 18 in the tapetum.As for the people who is familiar with this technology with conspicuous, preferably adhesive layer is in moist uncured state in the air-flow embossing process, so that villus fiber 18 is not subjected to the control of adhesive strictness, can change their position and orientation along with the bump air-flow.The air velocity of bump tapetum should apply enough big power to villus fiber 18, so that the reorientation of fiber reaches the degree of expection.After 112 embossing of embossing cylinder, velour solidifies adhesive layer, thereby embossed pattern for good and all is fixed up by solidifying cabin 116.Solidify cabin 116 can by any will be through embossing but traditional curing apparatus that still uncured velour is exposed under the radiation that promotes adhesive layer curing form.Operate by flocked fabric is exposed under the radiation source such as infra-red radiation, heat radiation or ultraviolet radiation in the typical cabin of solidifying.In some preferred embodiments, solidify cabin 116 and comprise that the technical well-known flocked fabric that makes is exposed under the thermal current so that the convective drying of adhesive and the air blast drying tunnel that is solidified into possible burning combustion gas.After the curing, embossing flocked fabric 118 withdraws from the curing cabin and is wound onto on the winding drum 120.Fabric can be according to a large amount of conspicuous variation of operating parameters of the people for being familiar with this technology by the transporting velocity of air-flow raging system 100.For some typical embodiments, this speed will be in the scope of about 25 to 150 feet per minute clocks.
Fig. 4 a-4c shows air-flow raging system 109 in more detail.Air-flow raging system 109 comprises air-flow raging system (Aigle Equipment ModelNo.AP-1, Burgano Toninese, the modified of selling on the market Italy).As what will become apparent for the people who is familiar with this technology, in alternate embodiment, characteristics of the present invention described herein can be used with other commercially available air-flow raging system, perhaps can incorporate the air-flow raging system that the client builds and designs into.In addition, below should be emphasized that just any specific size introduced of the embodiment of band illustration of the present invention, scale, material and other be exemplary purely, and be based on the practical operation condition of the embodiment of the specific band illustration of air-flow raging system 109.The present invention adopts other embodiment of alternative air-flow raging system to utilize to have the equipment that different scales and size and use are different from material specifically introduced here.Therefore, as what will become apparent for the people who is familiar with this technology, the specific scale that describes below, size, material and other provide purely for illustrative purposes, and can bi-directional scaling, modification or change for the air-flow raging system that characteristics of the present invention are applied to substitute.
With reference to Fig. 4 a, the flocked fabric 111 of not embossing is carried towards embossing cylinder 112 as previously described direction of pressing arrow 122 expressions.But that describes in more detail below embossing cylinder 112 comprises is arranged in the cylindrical shape stage casing that embossed surface 113 tops of embossed fabrics 111 not are made up of cylindrical shape template 128.Embossing cylinder 112 comprises that at its two ends diameter reduces template ring flange 130 (seeing clearlyer) in Fig. 5, and it is attached on the rolling bearing 132 of electrified driver element 134 whereby.Template ring flange 130 can utilize the template sectional fixture 136 of the known any traditional design of the people that is familiar with this technology to be attached on the rolling bearing 132.Electrified template-driven unit 134 comprises the supporting construction 138 and 140 of the width both sides that are configured in fabric 111.Have at least one to comprise the variable speed driver (not shown) that template 128 is rotated to traditional transmission mechanism power supply with respect to fabric 111 in the supporting construction 138 and 140.As conspicuous for the people who is familiar with this technology, making the transmission mechanism of cylinder rotation can be any technical known suitable transmission mechanism, comprising but be not limited to belt gear, gear drive, friction pulley transmission mechanism, induction transmission mechanism and other mechanism.The transmission mechanism of illustrated embodiment comprises gear drive, and the variable speed driver (not shown) makes successively the gear (not shown) rotation with the circumference gear (not shown) interlock of the outer surface that constitutes rolling bearing 132 in supporting construction 138 in supporting construction 140 in this transmission mechanism.
In the embodiment that illustrates, the variable speed driver that can operate drive pressure style face makes cylinder 112 according to the direction of arrow 143 (promptly, the direction opposite) or more preferably according to the direction of arrow 142 (that is, identical direction) rotation with the moving direction 122 of fabric 111 with the moving direction 122 of fabric 111.
In traditional prior art system, embossing cylinder 112 is the direction rotations of pressing arrow 142, thus the superficial velocity of template 128 in essence with template 128 below by the speed of fabric 111 identical.In this traditional embodiment, be complementary in the velocity of rotation of the scope inner pore 144 of the template 128 of embossing cylinder 112 speed, thereby cause embossing position 22 in air-flow embossed fabrics 118 to have in essence identical with the total length of hole 144 on the template of measuring along the direction of rotation 142 that forms the embossing position 128 total length of measuring by moving direction 122 with the fabric 111 that passes through below.Utilization drives according to variable speed driver provided by the invention, in some embodiments, in order on fabric, to produce various embossed patterns with the visual effect that has nothing in common with each other with single given template, template 128 can be different from template below by the speed rotation of fabric speed.

The view of the air-flow raging system 109 that Fig. 4 c sees when being illustrated in fabric 111 following observations.In preferred embodiments, system 109 comprises the stayed surface 236 that directly is positioned at below the template 128, but it when being installed in the system in order to dispose in the bottom surface that the embossed surface of fabric is compressed the position supports fabrics 111 of the airflow strikes that the nozzle ejection of air gun goes out during operation.Although in the alternate embodiment of the embodiment that illustrates with Fig. 4 c, stayed surface can comprise platform or other smooth surface,, as what illustrate, preferably stayed surface comprises columnar fabric-supported cylinder 104.
In the embodiment that illustrates, fabric-supported cylinder 104 is installed on the cylinder hold-down arm 198 that is being supported by cylinder brace summer 200.In some embodiments, cylinder hold-down arm 198 can be configuration like this, so that the upright position of fabric-supported cylinder 104 can be adjusted with respect to cylinder brace summer 200, fabric 111 and template 128 by the direction of arrow 199.In preferred embodiments, fabric-supported cylinder 104 is in order to rotate, most preferably to dispose according to the direction of motion identical with fabric 111 directions 201 rotations.
In the embodiment that illustrates, fabric-supported cylinder 104 is by being placed in power rotation that motor 202 on the motor support platform 203 and driving belt 204 transmit.In alternate embodiment, as becoming fairly obvious for the people who is familiar with this technology, fabric-supported cylinder 104 can rely on various alternative mechanical devices to rotate.In the preferred embodiment that illustrates, provide the removing surface key element 206 that contacts with the outer surface 236 of fabric-supported cylinder 104.The effect of removing surface key element 206 is the adhesive that may concentrate on the surface 236 of fabric-supported cylinder 104 any; villus fiber or other fragment are wiped off and are removed, thereby restriction system can be in the fragment assembly that need not to shut down any operating period of clearing up the time span of operating under the surface-supported situation usually in prior art system for elimination or minimizing.In the embodiment that illustrates, removing surface key element 206 comprises in essence along the scraper plate of the cylindrical external surface 236 of the whole width location of the fabric-supported cylinder of 128 belows, template zone that directly are positioned at embossing cylinder 112 and contact fabric back-up roller 104.In the most preferred embodiment, the removing surface key element is adjusted in essence whole length and the back-up roller position contacting along the cylinder that contacts with fabric 111 bottom surfaces.The people who is familiar with this technology is easy to imagine and many other removing surface key elements that can be used for replacing scraper plate 206, for example brush, air-spray, water jet or the like, and they all are contemplated within the scope of the present invention.
Fig. 5 is the profile of air-flow raging system 109.In order to illustrate the relative position of some different key element in the system 109, Fig. 5 illustrates the cutaway view of air-flow raging system 109 with an embodiment that is installed in the compressed ir spray gun provided by the invention in the system scope, and some details of the supporting construction is not for the sake of clarity illustrated.
Compressed ir spray gun 210 is similar to the following compressed ir spray gun 700 that illustrates in more detail and discuss with Fig. 8 a-8f at design aspect.As previously discussed, compressed ir spray gun 210 has the air inlet zone of being supported and being located by compressed ir spray gun air inlet support arm 150 and compressed ir spray gun air inlet height adjuster 162 when being operably mounted in the air-flow raging system 109, and has the installation shaft that is supported and located by compressed ir spray gun installation shaft support arm 152 and compressed ir spray gun installation shaft height adjuster 178 in its downstream.
Compressed ir spray gun 210 illustrates and can place very a embodiment near the compressed ir spray gun of the position of template inner surface to one or more nozzles of compressed ir spray gun.Compressed ir spray gun 210 in a tubular form the conduit moulding and comprise above have the parts 214 that form nozzle to adhere to main part 212.The parts 214 that form nozzle comprise nozzle 216 at its end, and its shape and position make nozzle can be placed in very position near the surface 218 of the inner surface of template 128, wherein surface 218 in the face of and adjoin nozzle and directly adjoin fabric 111.
As what discuss in more detail below, for minimizing along the pressure drop of compressed ir spray gun length and in order to provide the air-flow of expection to distribute in the empty scope of compressed ir spray gun, the whole length of main part 212 compressed ir spray gun that preferably air flows by its when compressed ir spray gun is in mode of operation has consistent in essence diameter.Therefore, because the actual restriction of forcing of air-flow raging system, have directly the nozzle that on the sidewall of the main part of compressed ir spray gun, forms and do not comprise the position that can not in the embossing Cylinder Range, be placed in the inner surface that makes the very close template of nozzle as the parts 214 that form nozzle from the compressed ir spray gun of traditional prior art of the parts of the protruding formation nozzle of the sidewall of main part.
The actual restriction that the air-flow raging system hinders the nozzle that directly forms in the sidewall of traditional compressed ir spray gun to be placed in very near the position of the inner surface of template is because the difference of the minimum interior diameter 219 in the template ring flange 130 of the internal diameter of template 128 and air-flow raging system and hole 148.Discussed as the front, with regard to utilizing internal diameter is that 7.95 inches, exterior periphery are that 25 inches, the internal diameter of ring flange are approximately with regard to 51/2 inch the typical equipment of template, has about 1.2 inches distance 220 between the inner surface 223 of the inner surface 222 of hole 148 and template ring flange 130 and template 128.With regard to the parts that do not form nozzle but have diameter and equal or be similar to regard to traditional compressed ir spray gun in air inlet zone of main part diameter, the nozzle that forms in the sidewall of main part will be restricted owing to the air inlet parts contact surface 222 of compressed ir spray gun, and this contact will make nozzle can not be positioned at position apart from the distance of the inner surface 218 of template 128 much smaller than distance 220.
Extend but the parts 214 of formation nozzle that do not extend to the air inlet parts of main body can be built bridge on distance 220 along the most length of main part 212, make the nozzle 216 can be as the position of being placed in of expection near the surface 218 of template 128.As below with reference to Fig. 8 a-8f in more detail as described in, the parts 214 that form nozzle preferably extend along the length across the main part 212 of the whole width of template 128 and fabric 111 in essence, but do not extend in the main part in the zone of adjoining inner surface 222.
The pressure drop of any length along compressed ir spray gun 210 is minimized when being in mode of operation, the internal diameter of main part 212 is increased to normally satisfactory to greatest extent in system.In addition, the size that adjust to form the parts 214 of nozzle makes it stretch out a segment distance from the outer surface of main part 212 nozzle 216 parts that form nozzle to be placed in meet the requirements apart from the distance on the surface 218 of template 128 and to be absolutely necessary.Therefore, forming the shape of parts 214 of nozzle and position is enough to make nozzle 216 and surperficial 218 distance of separating much smaller than gas outlet on the main part 212 224 and surperficial 218 distances of separating." be far smaller than " and when relating to nozzle 216 previously discussed and the surface distance between 218 and gas outlet 224 is compared with surface 218 distances of separating, represent nozzle 216 and surperficial 218 distances of separating are no more than about 60% gas outlet 224 and surperficial 218 distances of separating, and in certain preferred aspects can be less than 1% of the distance that the surface 218 of the gas outlet on the main body of compressed ir spray gun and template is separated.
In the embodiment that illustrates, the main part 212 of compressed ir spray gun 210 comprises about 1/8 inch of wall thickness, the about 4 inches aluminum pipe of external diameter.In other embodiment, compressed ir spray gun 210 can with various other material (for example, other metal, plastics, or the like) constitute, and selected wall thickness can be different from aforementioned wall thickness in order to provide enough opposings to operating pressure with regard to the material of choosing, and this will be conspicuous for the people who is familiar with this technology.As previously discussed, main part 212 is included in the gas outlet 224 that parts 214 fluids with forming nozzle above it are communicated with.Gas outlet 224 can comprise numerous through holes on the sidewall of main part 212; But in such as the such preferred embodiment of the embodiment that is illustrated, gas outlet 224 comprises as the sort of elongated long and narrow hole that extends along most length of main part that more clearly illustrates in Fig. 8 a-8f.In addition, for the expansion of opposing main part 212 when compressed ir spray gun is in mode of operation, main part 212 can be one or more soldered or otherwise keep stable attached to the support bar 226 relative interior pressure across the inside of gas outlet long and narrow hole 224 of main part 212 by comprising along its length.Usually, when being in mode of operation, attached on the source of the gas 114, this source of the gas preferably includes the variable-speed blower that the volume flow rate of the air of being adjusted by the user can be provided for compressed ir spray gun 210 as the air inlet of the compressed ir spray gun of showing with Fig. 3 210.In the scope of compressed ir spray gun 210, typical operating pressure can be at about 1 inches of water(in H and is approximately changed between the .100 inches of water(in H.
The parts 214 that form nozzle can be made for the conspicuous suitable material of the people who is familiar with this technology with any, and are metal by rigidity in preferred embodiments.The parts 214 that form nozzle are across the gas outlet long and narrow hole 224 of main part 212 and comprise the curved upper surface 225 that shape is consistent with the profile of main part 212 outer surfaces.The parts 214 that form nozzle can be by being attached on the main part 212 for the conspicuous any means of the people who is familiar with this technology.In the embodiment that illustrates, removably be attached on the main part 212 by being tied to through the numerous screws 228 of length in the location, both sides of gas outlet long and narrow hole 224 along the parts that form nozzle at the parts 214 that form nozzle.
As what illustrate, the parts 214 that form nozzle comprise the interior compartment 230 of extending with nozzle 216 along the length of the parts that form nozzle.Nozzle 216 can comprise numerous single holes or mouth in the lower surface scope of the parts 214 that form nozzle; But, for fear of the cutter trade that causes by the air-locked interval between the nozzle that comprises single hole or eyelet, but in preferred embodiments nozzle 216 comprise along most length of the parts 214 that form nozzle extend and in the system of being installed to the time across the elongated rectangle long and narrow hole of the width of the embossing of the width of template 128 and fabric 111.
In preferred embodiments, nozzle long and narrow hole 216 extends along the length of the parts 214 that form nozzle, thus it with main part 212 on gas outlet long and narrow hole 224 same prolonging, and directly align with following parallel gas outlet long and narrow hole.In the embodiment that illustrates, the parts 214 that form nozzle stretch out from main part 212, so that nozzle 216 and gas outlet 224 are enough to stride across when being configured in the air-flow raging system scope location surface 218 and surface 222 whole distances of separating 220 separately by exercisable at compressed ir spray gun.The main part 212 of 4 inches external diameters that for example, illustrate and the combination of parts 214 of extending the formation nozzle of about 1.25 inches distances from main part will cause total effective diameter 232 of compressed ir spray gun 210 just in time to be enough to equal the template ring flange 130 of air-flow raging system and the minimum diameter 219 in hole 148.
What determined already according to the present invention is because the position of nozzle 216 very near the surface 218 of directly adjacent with fabric 111 template 128, is better than the degree of traditional compressed ir spray gun at the air-flow of the some ejaculation by the embossing template so the degree of collimation of the air-flow 231 that the point that passes template 128 at air-flow penetrates from nozzle is enhanced.By reducing nozzle 216 and surface 218 distances of separating, the length of air-flow 231 correspondingly is shortened between nozzle 216 and surface 218, and the quantity of the dispersion of air-flow reduces significantly, thereby causes having the ability realizing the much fine and smooth details and the improved outward appearance at the embossing position of embossed fabrics 118.As what be described in more detail below, nozzle 216 very near the surface 218 of template 128 and the parts 214 that form nozzle effectively airflow direction from the direction of the longitudinal axis 320 that is parallel to compressed ir spray gun 210 in essence change in essence ability perpendicular to the direction of this longitudinal axis combine make air-flow 231 can by perpendicular to the degree on the surface of fabric 111 than being directed with traditional compressed ir spray gun much better than direction in the cards.
As the front with reference to as described in 4a and the 4b, 210 positions of compressed ir spray gun and can handle height adjuster 162 and 178 to the distance that the surface 218 of nozzle 216 and template 128 separates when needed by the operator and adjust.In addition, in addition, as previously described, nozzle 216 can be adjusted with vertical adjustment dog screw 194 (seeing Fig. 4 b) with round handle 192 by the angle adjustment dog screw with respect to the angular orientation of center line 190.
As what illustrate with Fig. 5, compressed ir spray gun 210 is so positioned, so that the adjustment long and narrow hole on its installation shaft (for example, see Fig. 8 a-8f) be adjusted dog screw 194 interlocks, thereby make center line 190 location of nozzle 216 along template 128, but so that guiding in essence perpendicular to the air-flow 231 of the embossed surface 113 of surface 218 and fabric 111.In preferred embodiments, nozzle 216 is to locate like this, so that the surface 218 of it and template 128 is no more than about 0.75 inch distance separately during operation, thereby causes the length of air-flow 231 between nozzle 216 and surface 218 to be no more than about 0.75 inch.In other preferred embodiment, nozzle 216 and surface 218 distances of separating are no more than about 0.5 inch, in other embodiment, be no more than about 0.25 inch, in other embodiment, be no more than about 0.1 inch, in other embodiment, be no more than about 0.05 inch, in other embodiment, be no more than about 0.025 inch, be no more than about 0.0125 inch in other the embodiment, and in other embodiment, be no more than about 0.01 inch.
In addition, preferably adjust the upright position of fabric-supported cylinder 104 and fabric 111 like this, so that the outer surface 233 of most of upper surface 113 of tapetum 16 and template 128 is no more than about 0.02 inch distance separately, and wherein surperficial 233 directly adjoin inner surface 218 and are positioned directly at the top of tapetum 16.In other embodiment, but the surface 233 towards fabric of template 128 is placed in apart from the distance of the embossed surface of tapetum 16 and is no more than about 0.01 inch position, this distance is no more than 0.005 inch in other embodiment, and this distance is no more than about 0.001 inch in other other embodiment.Therefore, desirable be the surface 233 and tapetum 16 between distance very little, do not contact with the physics of tapetum 16 but in fact have to tend to make fine hair space (pile air) to be out of shape with the surface 233 that forms undesirable observable cutter trade.
In addition, as what illustrate with Fig. 5, preferably the stayed surface 236 of fabric-supported cylinder 104 is to locate like this, so that its most of upper surface 238 aligns with center line 190, make surface 238 be directed into the following of nozzle 216 and with the nozzle position spaced, thereby the air-flow 231 that guiding is penetrated from nozzle adjoins and fabric is clashed in the position that contact stayed surface 236 at fabric 111.But this structure prevents fabric and is pushed and keep open the distance of the expection between the tapetum 16 of template 128 and embossed fabrics 111 by air-flow 231 from the embossed surface of template 128.
The another kind of method that improves the ability of the degree of collimation of air-flow 232 and the embossability that compressed ir spray gun 210 produces exquisite embossing details and expection is the feature perforation size of comparing and reducing nozzle 216 significantly with the feature perforation size of nozzle in traditional compressed ir spray gun." the feature perforation size " of the nozzle of Shi Yonging refers to the minimum transverse cross-sectional dimension of nozzle in this article.Comprise in the embodiment of elongated rectangular slot that at the nozzle 216 that is illustrated feature perforation size 240 comprises the width of the nozzle 216 that elongate slit forms.With regard to the embodiment that nozzle comprises circular hole, the characteristic size of each nozzle will be the diameter that forms the circular hole of nozzle.Equally, for other shape, the cross sectional dimensions of the minimum of the nozzle that characteristic size can be by measuring given shape is determined (for example, with regard to oval-shaped nozzle, the feature perforation size will comprise oval minor axis length).In preferred embodiments, the feature perforation size of the nozzle of the compressed ir spray gun that is provided according to the present invention is less than about 0.2 inch.In other preferred embodiment, the feature perforation size of nozzle is no more than 0.1 inch, in other embodiment, be no more than 0.05 inch, in other embodiment, be no more than 0.01 inch, in other embodiment, be no more than about 0.005 inch, in other embodiment, be no more than about 0.001 inch.
Except the degree of collimation that improves air-flow 232, the characteristic size of the nozzle by reducing compressed ir spray gun provided by the invention, effective through hole gross area that the nozzle that air communication crosses is arranged are the very little parts of internal cross-sectional area of main part that the compressed ir spray gun of air-flow is provided for nozzle.Therefore, the air-flow that usually nozzle provided of the compressed ir spray gun of the present invention that nozzle feature perforation size is quite little has the high resistance that obtains of compressed ir spray gun design than traditional prior art.In preferred embodiments, the effective through hole gross area that provides by the nozzle of compressed ir spray gun provided by the invention be no more than compressed ir spray gun main part internal cross-sectional area about 15%.In other preferred embodiment, nozzle area is no more than total effectively through hole cross-sectional area about 7.5% of the main part of compressed ir spray gun, in other embodiment, is no more than about 1.5%, in other embodiment, be no more than about 0.1%.
By such design compressed ir spray gun of the present invention most of resistance to air-flow is provided by nozzle, pressure drop along the length of compressed ir spray gun can be greatly reduced, and compares with traditional compressed ir spray gun design along the air-flow that the length of compressed ir spray gun penetrates from nozzle and can produce the distribution that is in admirable proportion.In some preferred embodiments, by the very little nozzle of use characteristic perforation size, the speed of the nozzle of air communication overcompression air gun can that section compressed ir spray gun length along nozzle along its location keep invariable in essence.This air velocity that ejects from compressed ir spray gun can cause keeping along the whole width of fabric 111 in essence the height homogeneity of embossed pattern along the homogeneity of spray gun length.
