Definitions
- the invention relates to a carrier provided on its visible side with a finish having a grain structure, a velor-like, fine-fiber top, in particular a grain leather with a ground grain side forming the upper surface, a split leather with a ground surface or a synthetic velor material with a surface consisting of microfibers, wherein dressing consists of a solidified plastic dispersion and is produced separately on a base with a structured surface corresponding to the grain structure and is connected to the latter via a connecting layer formed from a solidified, polyurethane-containing plastic dispersion, which is applied to the top of the carrier.
- the term "scar structure” is also intended to mean a nubuck-like design of the visible side of the finish.
- Full-grain leather, so-called aniline leather which is only colored but does not have a finish on its scar side, desirably has a particularly high permeability to air and water vapor, however, is with these
- the dressing is first produced separately on a base made of silicone rubber, the base having a structured surface corresponding to the grain structure of the dressing.
- a plastic dispersion which contains a maximum of 60% by weight, generally 40% by weight solids, is first applied to the structured surface of the substrate by knife coating, spraying, roller application or casting and is allowed to solidify by the application of heat ,
- the wet plastic dispersion has a smooth surface immediately after application, but when it solidifies, the film formed by this plastic dispersion shrinks due to the removal of water, the dispersion sagging into the valleys of the structure of the base, and only a very thin or possibly even a non-contiguous layer of the Dressing occurs, especially when the dressing is to have an elegant, deep grain and therefore the underlay has a corresponding, strongly pronounced structure.
- Dressing and the surface of the leather at least one layer, usually several layers to compensate.
- a thick compensation layer which also serves as a connecting layer. Adhesion problems often arise between the individual layers, so that the layers are at least partially detached.
- a major disadvantage of the known leather provided with a finish, particularly when at least one compensating layer is provided, is that the required air and water vapor permeability is not present, since the compensating layer contains the pores or open cells that may be present in the thin finishing closes. This negatively affects the breathability of the leather provided with the finish.
- Carriers are also known, the dressing of which is prepared separately by applying a dispersion containing polyurethane and a crosslinking agent to a warm surface.
- the application is carried out by knife coating, casting or by means of rollers, it being impossible to produce a uniformly thick, film-like finish.
- the invention proposes that the dressing has continuous capillaries over its entire thickness and both in the area of the grain tips and also in the area of the grain valleys has essentially the same thickness, and is connected to the carrier via a single thin connecting layer. Due to the arrangement of the continuous capillaries both in the area of the scar domes and in the area of the scar valleys, if only a single thin connecting layer is provided, the required air and water vapor permeability is substantially improved, while at the same time ensuring that the thickness is essentially the same everywhere having dressing has no weak points and has the same strength at all points, so that the dressing is not damaged even when the wearer is subjected to bending and tensile stresses.
- a mechanical perforation of the carrier provided with the dressing, which leads to a weakening of the carrier, in order to achieve the desired air and water vapor permeability is therefore not necessary in the configuration of the carrier according to the invention.
- Another advantage is that so-called "low water absorption leather” can also be finished in the manner according to the invention, these leather breathing, ie permeable to air and water vapor, but with a large amount of water, such as rain, the water,
- the capillaries can expediently have a different cross section with a diameter between 0.005 mm and 0.05 mm, preferably between 0.009 mm and
- the capillaries are distributed irregularly in the dressing, so that the visible side of the dressing has the appearance of the pore structure of a natural skin. Optimal air and water vapor permeability is ensured if, according to a further feature of the invention, the connecting layer has interruptions or weak points of reduced thickness.
- the continuous pores mentioned can be made visible by applying a colored contrast agent to the surface of the dressing and allowing it to penetrate into the pores, and, after drying, take sectional views of the carrier provided with the dressing.
- the interruptions or weak points in the connection layer are preferably achieved in that the connection layer is only partially arranged on the surface of the carrier, so that no coherent layer is formed. It has been shown that in this case too there is an adequate connection between the carrier and the dressing, a very high permeability to air and water vapor being ensured. In addition, this also achieves the desired softness and extremely high abrasion resistance, so that the parameters necessary for the interior, in particular in the vehicle industry, are met, although good adhesion between the dressing and the carrier is nevertheless ensured.
- connection layer has a point-like, grid-like or grid-like, that is to say network-like structure, so that there are interruptions and there is no full-surface, rigid sandwich construction which adversely affects the permeability to air and water vapor, but also the ability to bend ,
- the connecting layer has a maximum thickness between 0.01 mm and 0.05 mm and at its weak points a thickness between 0.002 mm and 0.01 mm, in which case a good one Air and water vapor permeability is achieved via these thin weak points and through which the bendability and surface adhesion of the leather are significantly improved.
- the connecting layer is predominantly arranged in the region of the fiber tips, so that cavities causing a pump effect are kept free between these fiber tips when the carrier provided with such a dressing is loaded. It has been shown that in this case an adequate connection is achieved between the fibrous surface of the carrier and the dressing, the required high permeability to air and water vapor, in particular also being ensured by the pump effect mentioned.
- This pumping effect has the effect that when pressure is exerted on the dressing, for example by sitting on one with one Trimmed carrier provided seat, the dressing is compressed, and when the dressing is relieved of pressure, a suction effect arises, as a result of which moisture is rapidly absorbed by the carrier.
- the connecting layer consists of a solidified, polyurethane-containing, crosslinked plastic dispersion, in particular of a solidified polyester-polyurethane dispersion. It is advantageous if the polyurethane-containing dispersion has at least partially a crystalline or a partially crystalline structure.
- connection layer consisting of such a dispersion is thermoplastic and has a very low softening point, especially if it still contains between 2% and 10% water but already feels dry.
- a connection layer on the one hand ensures a good connection between the upper side of the carrier and the dressing, but also ensures that it does not penetrate deeply into the gaps between the fibers or tufts of fibers on the upper side of the carrier and hardens it, and, if it is crosslinked, is heat-resistant , It is advantageous for a good connection if the plastic dispersion contains tacky additives, for example soft resins or soft polymers, in particular acrylates, by means of which the adhesive effect of a dispersion which has already partially solidified is improved. According to a further feature of the invention, the plastic dispersion
- the connecting layer has a weight per unit area between 20 g / m 2 and 90 g / m 2 .
- the basis weight is expediently between 20 g / m 2 and 45 g / m 2
- Optimal values with regard to air and water vapor permeability are achieved if the finish not only has essentially the same thickness in all cross-sectional areas, but also approximately the same structure and the same density and thus has the same strength at all points and no weak points are present which lead to damage to the dressing in the event of bends and tensions in the support provided with the dressing.
- the dressing preferably consists of a combination of a solidified polyurethane dispersion containing a crosslinking agent with a high softening point and a solidified polyurethane dispersion containing a crosslinking agent with a preferably crystalline or partially crystalline structure with a low softening point, which dispersion is thermoplastic before crosslinking.
- the desired properties can be optimally achieved by the combined use of a polyurethane dispersion, which leads to temperature-resistant films with elastomeric properties even before crosslinking, with a thermoplastic polyurethane dispersion with a preferably crystalline or semi-crystalline structure, as used as a raw material for adhesives.
- the dressing may contain hollow microspheres forming closed cells with a diameter of less than 21 ⁇ m.
- the dressing does not have a foam structure which stores liquid in an undesired manner, but the permeability to air and water vapor is brought about by the continuous capillaries.
- the grain tips of the dressing can have microscopic, smooth elevations.
- the invention also makes it possible to give the visible side of the dressing a nubuck structure from which fine hairs protrude, which likewise form small elevations.
- the elevations expediently have a diameter between 3 ⁇ m and 60 ⁇ m, preferably between 5 ⁇ m and 15 ⁇ m, and a maximum length of 110 ⁇ m, and are arranged close together.
- These elevations which can have the appearance of fine hair, have the effect that, in particular, wet soiling remains on the smooth surface of these elevations and does not sag into microgaps between the grain tips or in the nubuck structure, and thus prevents the dirt from settling all over on the surface of the Dressing times.
- the positive effect is further improved if the finish contains waxes and / or silicones on its visible side, by means of which the surface tension of the finish is changed with respect to water.
- the visible side of the dressing can be provided with a very thin finish which does not impair the permeability to air and water vapor, but which can be used to influence the handle and the degree of gloss.
- a strongly roughened synthetic fabric or knitted fabric with protruding fibers can be provided on the side of the carrier opposite the upper side, in particular the meat side of a leather used as the carrier, which preferably has a weight per unit area of more than 250 g / m 2 .
- the adhesive connection of this woven or knitted fabric to the carrier is carried out in such a way that only an adhesive effect is produced between the fibers.
- This woven or knitted fabric can be covered by a thin coating.
- Animal skin, from which leather is made, is an expensive commodity, so this skin should be used optimally.
- the method according to the invention for producing a support provided on its visible side with a scar structure, in particular a scar leather, a split leather with a sanded upper side or a synthetic velor material with an upper side consisting of microfibers first of all to form the dressing an aqueous plastic dispersion onto a silicone rubber existing base, which has a structured surface corresponding to the grain structure of the dressing, is applied and allowed to solidify to form a film, further a plastic dispersion forming a connecting layer is applied to the top of the carrier, and further the carrier is placed with this top on the film and one Is subjected to pressure and heat treatment, consists essentially in that the plastic dispersion containing a solvent-free, polyurethane and a crosslinking agent on the uniform Temperature of less than 105 ° C.
- the plastic dispersion consists of a combination of a polyurethane dispersion containing a crosslinking agent with a high softening point, and a polyurethane dispersion containing a crosslinking agent, preferably having a crystalline or partially crystalline structure with a low softening point, which dispersion is thermoplastic prior to crosslinking.
- the plastic dispersion is applied to the base by means of of a fine spray produced by a small diameter spray nozzle in such a small amount that water is withdrawn from the plastic dispersion on the way to the heated base and this plastic dispersion solidifies at least to the extent that it hits the base at least to such an extent that the plastic dispersion does not penetrate into the base Can scar valleys of the structured base, but rather forms an equally thick, net-like film at all points, which creates the capillaries mentioned.
- the structured surface of the underlay is preferably produced by molding the grain structure of a natural leather. In particular, if the surface of the dressing is to have a velor effect, it is also possible to pass through the structured surface of the base
- a base consisting of addition-crosslinked silicone rubber with a Shore hardness between 25 Shore A and 70 Shore A is preferably used.
- Such a base is pressure-elastic in the desired manner, so that the scar image is not destroyed during the final pressure and heat treatment.
- laser treatment of addition-crosslinked silicone rubber does not result in free radicals that make the impression more difficult, so that depressions can be formed in the silicone rubber, which later have the appearance of the finest hairs or the finest tufts of fibers on the dressing and lead to a nubuck effect.
- the pad expediently consists of a thermally conductive silicone rubber with a density of more than 110 g / cm 2 , preferably of more than 120 g / cm 2 and thus has good thermal conductivity, which is necessary for uniform heating during the spray application of the plastic dispersion.
- To increase the Thermal conductivity can be embedded in the base inorganic fillers.
- the base preferably has a thickness between 1 mm and 3 mm and is connected to a thermally conductive support, preferably made of aluminum, which can have a thickness between 1 mm and 3 mm.
- This heat-conductive support ensures an even heat distribution on the surface.
- the base is connected to the thermally conductive support by means of a one-component adhesive in which a thin nonwoven material made of synthetic fibers with a basis weight of less than 150 g / m 2 can be embedded. This embedding does not hinder the thermal conductivity, but greatly limits the thermal expansion of the silicone rubber.
- a plastic dispersion is applied according to the invention, which essentially consists of a polyurethane dispersion with a low softening point and preferably a crystalline or partially crystalline structure and a crosslinking agent, in such a way that when it hits the top of the carrier solidifies quickly and a non-coherent connection layer is formed.
- a plastic dispersion can also be applied in such a way that a connecting layer with weak points of reduced thickness is created.
- the application is carried out in the same way as the application of the plastic dispersion to the silicone rubber base to form the dressing, in the present case by removing water from the dispersion when it hits the top of the carrier due to the water absorption by the carrier A net-like film is also formed on the top, as when the dispersion forming the dressing strikes the warm surface. If the leather used as a carrier is hydrophobic and therefore little
- the film on the base which has a network structure and forms the dressing, with the support placed thereon and provided with the plastic dispersion forming the connecting layer, is between pressure-elastic plates pressed at a temperature between 60 ° C and 105 ° C and at a maximum pressure of 5 kg / cm 2 .
- the film forming the connecting layer on the carrier becomes softer because of its low softening point than the film forming the dressing on the base, so that the capillaries remain in the dressing.
- the film forming the connecting layer does become sticky, but not liquid, so that the capillaries in the dressing are not closed by it and this film does not flow together, that is to say maintains its structure and the interruptions in the connecting layer are retained. It is thus ensured that, on the one hand, there is an adequate connection between the dressing and the top of the carrier, and on the other hand, the required air and water vapor permeability is guaranteed.
- the carrier provided with the finish can finally be subjected to residual drying after pressing in a hanging position.

- FIG. 10 schematically shows a device for connecting the dressing to the top of the leather.
- FIG. 11 photographically shows the visible side of the dressing provided for a leather according to the invention.
- the known preparation of a dressing 1 on a base 2 made of silicone rubber has hitherto been achieved in that, on the structured surface 3 corresponding to the grain structure of the finish 1 to be produced, this base 2 has a plastic dispersion by knife coating, spraying, roller application or casting is applied, which in the embodiment according to FIG. 1 contains about 55% solids.
- FIG. 2 shows a known leather 7 which is provided with a finish 1 according to FIG. 1. The side of the dressing 1 facing the base 2 in FIG.
- the grain valleys 8 of the dressing 1 now represents the visible side, so that, as can be seen from the drawing, the grain valleys 8 of the dressing 1 have an extremely small thickness.
- several compensation layers 9 and 10 must be provided between the leather and the finish 1, the compensation layer 9 in the embodiment shown in the drawing consisting of a foamed material and the compensation layer 10 forming the adhesive layer.
- These relatively thick compensating layers undesirably increase the overall thickness and, above all, cause pores or the like which may be present in the dressing 1 to be closed, so that there is no longer any air permeability and water vapor permeability is significantly reduced.
- 3 and 4 show a leather 7 according to the invention provided with a finish 1, in particular a leather sanded on its grain side or a split leather.
- the dressing 1 has essentially the same thickness d in the area of the grain tips and in the area of the grain valleys. There are therefore no weak points of reduced thickness which adversely affect the strength of the dressing 1.
- the dressing 1 has capillaries 11 of different cross-section which run essentially in a straight line and are continuous over the entire thickness, by means of which the required permeability to air and water vapor is ensured. These capillaries are arranged irregularly close to one another, so that the dressing 1 has the appearance of the pores of an animal skin, and have a diameter between 0.009 mm and 0.02 mm.
- the dressing 1 is connected to the leather 7 via a single, very thin connecting layer 12, which is largely permeable to air and water vapor.
- this connecting layer 12 can only be partially provided on the surface of the leather 7 or have weak points of reduced thickness and / or interruptions.
- the dressing 1 consists of a solidified dispersion which contains a proportion of polyurethane with an at least partially crystalline structure and a crosslinking agent, and has approximately the same structure and the same density in all cross-sectional areas. As can be seen from the right-hand part of FIG.
- the scar tips of the dressing 1 can be made with microscopic, densely arranged, smooth elevations 13 be provided with a diameter between 5 ⁇ m and 15 ⁇ m, which can also have the shape of fine hair or the finest tufts of fibers and have a maximum length of 110 ⁇ m.
- the area of the dressing 1 adjacent to the base 2 made of silicone rubber, which then forms the visible side contains small amounts of substances, such as waxes or silicones, which change the surface tension of the dressing 1 with respect to water.
- 6 shows a greatly enlarged cross section of an embodiment in which the leather 7 has a velor-like upper side 14, which is formed from the ground grain side when using a grain leather and from the finely ground finishing side when using split leather. Fibers or fiber tufts 15 protrude from this upper side 14, between which cavities 16 are kept free.
- the upper side 14 is provided with a porous dressing 1, which is formed from a base which is applied to a base made of silicone rubber and has a structured surface and is solidified by heating the same.
- the dressing 1 has continuous capillaries, which are not shown in the drawing.
- the pore structure formed by these capillaries is easily ascertainable if one removes the finish from the leather 7 mechanically or by chemical means and then holds it against a light source with slight stretching.
- the dressing 1 is connected to the upper side 14 of the leather 7 via a connecting layer 12 which, as the drawing shows, is only partially arranged, especially in the area of the tips of the fibers or fiber tufts 15, so that the Cavities 16 between these fibers or tufts of fibers 15 are essentially kept free. This results in a high permeability to air and water vapor, which is further improved by the fact that when the leather 7 provided with a finish 5 is loaded, a pump effect occurs.
- the connecting layer 12 is essentially on the velor-like upper side 4, which has the characteristic image of a polished split suede leather, which has a so-called "writing effect" before the dressing 1 is attached.
- the connection layer 12 concentrates on the upper region and partly on the lateral region of the fibers or fiber tufts 15, with at most only a small proportion of the connection layer 12 being arranged on the bottom of the cavities 16 between these fibers or fiber tufts 15, but this is is not connected to the connection layer 12 located in the upper and lateral region of the fibers or fiber tufts 15, so that air chambers are created between them Fig.
- the top is provided with a dressing 1 which has continuous capillaries 11 over its entire thickness.
- the dressing 1 consists of a solidified, polyurethane-containing, cross-linked plastic dispersion and is produced separately by applying an aqueous polyurethane dispersion in the form of a fine spray mist to a warm base 2 made of silicone rubber with a structured surface, which is applied immediately after impact the base solidifies, the required continuous capillaries 11 being formed in the solidified dispersion.
- the dressing 1 produced separately in this way is connected to this upper side immediately after it has solidified via a connecting layer 12 applied to the upper side of the leather 7.
- this connection layer 12 has a point-like, grid-like or grid-like, thus network-like structure, so that a connection between the upper side of the leather 7 and the dressing 1 and in between is made only at individual points or points Interruptions 17 occur which communicate with the capillaries 11 in the dressing 1 and thereby ensure the desired permeability to air and water vapor.
- the interruptions 17, which form a net-like structure can have any shape and, for example, be round, rectangular or linear, but also have any other suitable shape. In the embodiment shown in Fig.
- Interruptions 17 are provided in the connecting layer 12, but this also has weak points 18, the thickness of which is considerably less than the remaining thickness of the connecting layer 12, so that these weak points 18 also significantly increase the air and water vapor permeability and the flexibility and the adhesion between the top of the leather and the dressing is improved.
- the connection layer 17 expediently has a maximum thickness between 0.01 mm and 0.05 mm, but the weak points 18 only have a thickness between 0.002 mm and 0.01 mm.
- the meat side 19 of the leather 7 is provided with a strongly roughened synthetic fabric or knitted fabric 21 with protruding fibers, which can be covered by a thin coating 20. This gives the finished leather more volume.
- connection between the meat side and the woven or knitted fabric takes place by means of an adhesive in such a way that an adhesive effect is only produced between the fibers.
- an adhesive in such a way that an adhesive effect is only produced between the fibers.
- Such a design is particularly advantageous when using format blanks formed from the leather according to the invention for shoe manufacture, since in this case the open-pore thin coating serves as lining material and a separate application of such lining material is therefore not necessary.
- the large amount of moisture vapor permeability of the leather leads to the dissipation of foot sweat and, due to the high level of air permeability, ventilation of the interior of the shoe.
- the leather according to the invention for car seats and upholstered furniture the moisture occurring is absorbed by the finish from the leather.
- the continuous capillaries 11 provided in the dressing 1, which form a network structure, are clearly visible when illuminated with a 45-fold magnification and an elongation of 25%. If the dressing 1 is removed mechanically or chemically with the aid of solvents from the connecting layer 12, it can be seen even at a 16-fold magnification that the connecting layer 12 has both thick spots and weak spots and that pore-shaped interruptions are also provided in the weak spots.
- the dressing film has a maximum thickness of 0.06 mm at a contact pressure of 2 kg / cm 2 .
- 12 hollow microspheres with a diameter of less than 21 ⁇ m can be provided both in the dressing 1 and in the connecting layer.
- the leather of the invention has in relation to the air and
- Water vapor permeability has similar to the same properties as semi-aniline leather and is superior to mechanically perforated leather, but its visible side is also mechanically very resilient and lightfast and dirt-repellent.
- the present invention is primarily in cowhide, but also in their
- a pressure-elastic base 2 the structured surface 3 of which corresponds to the grain structure of the dressing 1 to be produced, and which is firmly connected to a heat-conducting support plate 23 made of aluminum sheet, is heated via heating devices in such a way that that the surface 3 of the base 2 has a temperature of about 80 ° C.
- a polyurethane dispersion in the form of a fine spray mist 25 is applied to this heated surface 3 via a small diameter spray nozzle 24, while the base 2 continues to move in the direction of arrow 26.
- the spray 25 solidifies by removing water, so that a thin, net-like film having capillaries 11 is formed on the base 2.
- a leather 7, on the upper side of which a plastic dispersion forming the connecting layer 12 has been applied is placed with this upper side on the film and pressed together with the base 2 in a press shown in FIG. 10.
- This has two metallic printing plates 27, 28 in which heating elements 29 are embedded.
- the pressure plates 27, 28 are mounted on supports 30 so as to be hydraulically movable.
- the upper pressure plate 27 is provided with a pressure-elastic pad 31.
- the leather 7, which has been placed with the upper side having the connecting layer 12 on the dressing 1 located on the base 2, is then positioned together with this base 2 between the pressure plates 27, 28, whereupon by means of these pressure plates an adjustable pressing pressure of approximately 3. 5 kg / cm 2 is exerted and at the same time the pressure plates 27, 28 are heated to a controllable temperature of approximately 90 ° C.
- the pressure-elastic pad 31, on the one hand, and the pressure-elastic design of the base 2, on the other hand, ensure that when the pressure is exerted, the capillaries 11 in the dressing 1 and the interruptions in the connecting layer 12 are retained, and therefore the required air and water vapor permeability is ensured.
- 11 shows the photograph of the dressing produced on a base 2 1, as it has the leather according to the invention.
- the right area A was illuminated with a light source from the underside and clearly shows that the dressing has a net-like structure, i.e. has continuous capillaries, the left area B, in which the underside was covered, clearly shows the scar structure of the Finishing.
- the invention was explained in connection with a leather as a carrier. Instead of leather, a synthetic velor material can always be used as a carrier.
- Example 1 A gray chrome-tanned, low-fogging calf leather with a thickness of approximately 1.2 mm and a size of 2.10 m 2 is lightly sanded on its grain side with 280 grit sandpaper, so that the hair pores are largely preserved , The leather is then drummed for six hours.
- a polyurethane dispersion mixture is applied in an amount of 88 g / m 2.
- the dispersion mixture consists essentially of 680 g of a non-thermoplastic polyurethane dispersion with a softening point of about 195 ° C, which does not after water removal can be melted because the destruction temperature is below the melting temperature, and from 250 g of a finely divided thermoplastic polyurethane dispersion with a softening point of about 62 ° C, its melting point is about 95 ° C and its adhesive point immediately after drying, but before crosslinking at a Temperature of about 55 ° C begins.
- this dispersion mixture has 4% by weight of an 80% polyisocyanate crosslinker, based on the polyurethane solids content of the dispersion, 8.5% by weight of black pigment also based on the polymeric solids content, 2.5% by weight of a silicone grip agent with a solids content of about 45%, 1% by weight of hollow microspheres based on the total weight with a diameter of less than 21 ⁇ m, and 0.5% by weight of an acrylate-based thickener.
- This mixture approach has a polymer solids content of approximately. 35% by weight. The application takes place without air admixture with two spray nozzles, each with a diameter of 0.46 mm, at a pressure of 65 bar.
- the two spray nozzles arranged one behind the other are arranged at a distance of 80 cm from the continuous support in the direction of movement thereof and at a distance from one another and move transversely to this direction of movement.
- the pad is slightly larger than the calf leather.
- the pad has passed the spray station with the two spray nozzles after about 14 seconds and is still at a temperature of 59 ° C. After exposure to dry air at about 85 ° C for about two minutes, the preparation prepared in this way, consisting of a net-like film, is water-free or almost water-free.
- a dispersion containing a polyurethane mixture is sprayed onto the leather, preferably also without admixture of air, with two spray nozzles, which have a nozzle diameter of 0.52 mm, at a spray angle of 80 ° emerging from the nozzles.
- the application amount is approximately 90 g / m 2 wet. With this spray application quantity, the fine droplets are withdrawn from the fine droplets immediately after the leather is wicked so much water that a network-like structure with many continuous capillaries is also produced here.
- the spray application is dry to the touch after three minutes and forms a thermoplastic connecting layer, and the leather can be placed on the dressing, which is preferably on the still warm surface, and connected to this dressing in a heated press between pressure-elastic supports , Due to the good thermal conductivity of the aluminum support plate, the heat is quickly absorbed by the press and passed on to the thermoplastic connection layer.
- a press heating plate temperature of 90 ° C a press pressure of about 2 bar on the leather and an inlet temperature of the underlay with the leather lying on it of 48 ° C, a dwell time in the press of less than 25 seconds is sufficient.
- connection layer The bond between the pressure-elastic surface of the underlay and the aluminum support not only offers advantages when pressing, but also when spraying, because the warm aluminum plate serves as a heat store and continuously releases heat to the underlay during the spraying process.
- the thermoplastic forming the connection layer
- Polyurethane dispersion mixture consists essentially of 700 g of a finely divided polyurethane dispersion with a softening point of about 62 ° C and a beginning adhesive point of about 55 ° C, 180 g of very soft polyacrylate, 200 g of polyurethane with a softening point of about 170 ° C, 9 wt. % Crosslinker based on the total batch, and 3% by weight of black pigment.
- the finished leather After finishing, the finished leather has almost the same softness as before. It has one Water vapor permeability of 3.6 mg / cm 2 .h and is so permeable to air that you can blow air through with your mouth.
- Example 2 A chrome-free tanned, low-fogging black cowhide skin with a thickness between 1.10 mm and 1.25 mm and a size of 5.2 m 2 was sanded on its grain side with 150 grit sandpaper and then milled (tumbled) for 12 hours. After milling, the flanks are spongy and double-skinned and would, if the entire skin was trimmed according to known methods, would result in approximately 50% of the surface being trimmed when the surface was designed with a medium-fine embossing. The centerpiece of the skin, which after the Millen is still somewhat grained and suitable for dressing with a medium-fine embossing, measures 1.95 m 2 .
- a plastic dispersion mixture in a quantity of 135 g / m 2 is applied in a quantity of 135 g / m 2 to a surface heated to 90 ° C., the structured surface of which corresponds in the negative to a medium-fine Nappa embossing, with three spray nozzles in such a way that a dressing is formed reticulated film is formed.
- the composition of the dispersion mixture differs from that given in Example 1 only in that instead of 680 g of non-thermoplastic polyurethane only 580 g and instead of 250 g thermoplastic polyurethane 350 g are used.
- the surface of the underlay is warm during the entire spraying process because the support plate made of aluminum sheet gives off heat to the underlay.
- the leather core which was used to form the
- the connecting layer as described in Example 1, was sprayed with the plastic dispersion, placed on the base at a temperature of about 39 ° C. and, as described in Example 1, pressed. After the pressing process, the leather was stored hanging for 30 minutes and then placed on a pallet. The trimmed surface shows no funnel-like sink marks, the numerous continuous capillaries are not visible. The water vapor permeability is 2.9 mg / cm 2 .h. You can blow air through the leather with your mouth.
- Example 3 Rough format parts for vehicle seats were punched out of spongy leather flanks.
- a first step the same mixture is sprayed in the same amount with two spray nozzles as described in Example 1.
- a uniformly strong, net-like film that forms the dressing forms on the scar tips as well as in the scar valleys.
- a mixture, as described in Example 2 is then sprayed in an amount of 60 g / m 2 onto the film, which is at about 65 ° C. and is on the base, using a spray nozzle.
- This spray application also solidifies when it hits the first warm spray application and thus reinforces the first film evenly both in the area of the scar tips and in the area of the scar valleys.
- a thermoplastic dispersion mixture forming the connection layer according to Example 1 was applied to the leather in an amount of about 55 g / m 2 in such a way that a predominantly coherent film with thicker and thin zones is formed.
- the application and pressing was carried out as described in Example 1.
- the finished leather no longer looks spongy, is soft and has a water vapor permeability of 1.95 mg / cm 2 .h, and you can blow air through it.
- Example 4 A finely sanded cowhide leather gap with a thickness between 1.2 mm and 1.3 mm and a size of 1.6 m 2 is prepared as described in Example 2. After it has been prepared, it is still permeable to air so that air can be blown through and has almost the same softness as before it was prepared.
- Example 5 To produce a leather with a nubuck-like finish, a base made of silicone rubber is used, which has fine depressions in addition to its rough surface. The depressions for the formation of the hair-like nubuck effects were introduced by laser treatment of the surface of the base. A particularly fine-particle, low-viscosity polyurethane dispersion with a solids content of approx.
- the dispersion consists of more than 80% by weight of non-thermoplastic polyurethane and contains 5% crosslinker and 4% of a 60% aqueous silicone emulsion as well as pigments.
- the application amount is approximately 60 g / m 2 .
- the silicone base is then heated to 60 ° C. and a polyurethane dispersion mixture, as described in Example 1, is applied to it with two spray nozzles. These two dispersion applications form the finish with a fine-mesh structure.
- a chrome-tanned cowhide the grain side of which was sanded with 320 grit sandpaper and milled for 8 hours, was cut to size for Car seats disassembled.
- a connection layer was applied to the format blanks as described in Example 1.
- the pressing was also carried out as mentioned in Example 1.
- the finished leather has a beautiful, comfortable nubuck surface and fulfills all parameters of the automotive industry. It is permeable to water vapor and air can be blown through the mouth.
- the carriers according to the invention have, compared to known carriers, irrespective of the processes by which they were produced, a substantially higher water vapor permeability with a comparable thickness of the dressing, and a high air permeability, which is completely absent in all other carriers with a comparable thickness of the dressing.
- These carriers also meet the CROCKMETERTEST required by the US automotive industry in combination with MEK.
- MEK penetrates the pores of the wearer, but without damaging the surface and without causing color changes.
- carriers that are finished with a nubuck surface that has the finest hairs meet all the parameters required by the automotive industry. They are easy to care for, do not become greasy, always remain matt and, unlike synthetic nubuck, are non-flammable and resistant to temperature and solvents.
- Example 6 In order to provide both a leather with a fine-fiber velor-like surface and a textile backing consisting of microfibers with a fine-fiber surface with a nubuck effect, so that both materials with the different backings later show the same surface in order to To be processed in combination in a vehicle or as upholstered furniture, the procedure is as follows.
- the pad is made of silicone rubber and has the negative
- Nubuck structure i.e. the surface is rough and has depressions that lead to the formation of the finest hairs or the finest tufts of fibers.
- the wells were brought into the substrate, close to each other, using a laser.
- This negative surface of the silicone rubber base was coated in a film-like manner with a plastic material in order to positively transfer the negative structure of the silicone surface to the plastic film.
- This plastic film serves as a mother for molding silicone substrates, which in turn contain the nubuck structure. This has the advantage that not every base made of silicone rubber has to be lasered, because according to the invention the lasered form can be reproduced via the nut.
- the underlay has a thickness of 2 mm and is bonded to an aluminum sheet and has a length of 2 m and a width of 1.5 m.
- the pad is heated to a temperature of 66 ° C and sprayed under the conditions as outlined in Example 1.
- Leather and a non-woven material made of microfibers, the cavities of which are filled with a coagulated polyurethane, are promptly sprayed with the velvet-like surface formed by the protruding microfibers, as described in Example 1, and are sprayed with the plastic dispersion after about 5 minutes, i.e. dry to the touch still warm pad placed and pressed under conditions as specified in Example 1.
- the material is removed from the press after about 15 seconds.
- nubuck has the high-quality nubuck effect with its fine protruding hairs, which have a writing effect typical of nubuck. You can blow through both nubuck materials and, after they have been crosslinked, you can press a cigarette out on them without damage. It can also be combined with many solvents, including petrol and MEK, without damaging the surface. Both materials have a pronounced pumping effect, which means that an applied drop of water pulls through the dressing into the carrier within a short period of time under pressure, loading and unloading. Both materials with the nubuck-like surface have the advantage over real nubuck leather that they do not become greasy. A relaxed drop of water that is applied to the surface is absorbed into the surface within two minutes without a pump effect.
- the synthetic backing material is always cut out of a web as a format or a large format part.
- a great advantage is that the leather and the textile backing made of microfibers are finished with the same nubuck surface and, if they are processed in combination, match perfectly in terms of color and feel and together old, this means that even after a long time, the dressing of both materials has the same appearance.
- the nubuck or nubuck effect according to the invention is always superior to a velor effect.
