Definitions
- the invention relates to textile surface products which are resistant to abrasion and / or provide protection against contact heat and / or are cut-resistant, and to processes for producing such textile surface products.
- materials which have high abrasion resistance are preferred to avoid excessive wear under normal use.
- Examples are functional garments in the sports and leisure sector, and professional and protective clothing.
- a high abrasion resistance is necessary to avoid or reduce injuries.
- leather is used for motorcycle clothing.
- plastic-based materials that have high abrasion resistance. However, all of these materials have the peculiarity of having little or no breathability due to their sturdy construction. In addition, such materials are usually stiff.
- the object of the invention is to provide textile sheet products which do not have the above-mentioned and other disadvantages.
- such textile surface products according to the invention should simultaneously have high abrasion resistance and high flexibility.
- Another object of the invention is to provide textile sheet products which are flexible and protect against contact heat.
- Yet another object of the invention is to provide textile surface products that are both cut-resistant and flexible.
- such inventive surface area products have a high breathability.
- the inventive principle of a textile surface product according to the invention is based on the fact that a multiplicity of coating elements are applied to a carrier layer, which, however, do not substantially influence the flexibility and flexibility of the carrier layer and any further layers present.
- the coating elements are designed abrasion resistant, and arranged so that when sliding friction of the textile surface product on a rough surface, only the coating elements come into contact with the rough surface. The textile carrier layer itself is thus protected from abrasion.
- abrasion-resistant textile surfaces Possible fields of use of such abrasion-resistant textile surfaces are sportswear, workwear, and protective clothing, for example for motorcyclists and firefighters.
- sportswear surface products according to the invention are very suitable because they can be designed to be breathable. It is thus possible, for example, to manufacture lightweight, breathable clothing for cyclists, which nevertheless does not rub through on the asphalt in the event of a fall of the cyclist, and thus can protect the wearer from skin injuries.
- Also advantageous is the use to protect very delicate textiles, or to protect exposed areas on garments with permanent friction, for example, outdoor jackets in the area where scrubbing backpack.
- a textile surface product according to the invention also protects against contact heat, since only the coating elements can come into direct contact with a hot surface.
- a possible field of application are, for example, work gloves.
- a textile surface product according to the invention is characterized by a multiplicity of coating elements, which are arranged on a surface of a textile carrier layer of the surface product in such a way that only a part of said surface of the carrier layer is covered by the coating elements.
- the coating elements consist of a material that is essentially a mixture of a polymer material, preferably a thermoset-crosslinkable prepolymer, and a filler in the form of inorganic and / or metallic particles.
- the coating elements are distributed over the support layer such that the textile surface product with coating elements substantially corresponds in its flexibility to the textile surface product without coating elements.
- the coating elements may, for example, be punctiform or circular.
- An advantageous arrangement of coating elements comprises, for example, staggered, circular coating elements with a diameter of about 4 mm, and a distance between the adjacent coating elements of about 2 mm.

- FIG. 4 shows diagrammatically cross sections of further exemplary embodiments of surface products according to the invention.
- Figure 5 shows an advantageous arrangement of coating elements on a surface product according to the invention, in which no continuous cutting edge exists.
- FIG. 1 A basic example of a textile surface product 1 according to the invention is shown in FIG.
- a carrier layer 1 1 On a carrier layer 1 1 a plurality of coating elements 2 is arranged.
- the carrier layer 11 in the present example is the only textile layer of the surface product 1. It can be designed as a fabric, ash, or fleece. In any case, however, it is advantageous that the coating material to be applied can flow into the structure of the carrier layer 11 at least superficially in a viscous, uncured state, in order to achieve a positive connection of the coating layer after curing. To reach elements 2 with the carrier layer. The procedure for applying the coating elements will be discussed below.
- the coating elements 2 are designed as circular, raster-shaped elevations. However, other shapes and arrangements are also possible.
- the first carrier layer 1 1 is made comparatively thin, and arranged on a second layer 1 2, which may be thicker.
- a second layer 1 2 which may be thicker.
- the first layer 1 1 can be configured, for example, as a thin but stable, tear-resistant fabric.
- the cured coating elements 2 are arranged on a surface 1 1 1 of this carrier layer, and positively connected to the fabric 1 1. This side of the carrier layer thus forms the outer surface / right side 1 0 of the textile surface product, which is protected against abrasion or contact heat.
- the second layer may for example be designed as a knitted or foamed polymer that has a certain thickness and thus acts as a cushioning layer.
- the two layers can be bonded together or laminated together.
- the layers can be joined together before applying the coating elements, or subsequently.
- FIG. 3 The mode of operation of a textile surface product according to the invention is illustrated, for example, in FIG. 3 as a schematic cross section through a carrier layer 11 having a single coating element 2. This has the form of an elevation which projects beyond the surface 11 of the carrier layer.
- part of the polymer material penetrates into an upper layer of the textile structure of the carrier layer.
- the polymer material flows around the fiber structure of the carrier layer, and forms after curing an extremely stable, positive connection.
- the particles 22 of the filling material are positively fixed in the polymer matrix 21 of the coating element.
- the plurality of coating elements 2 can be due to the arrangement of the two the carrier layer 1 1 essentially only the coating elements 2 come into contact with this rough surface.
- the carrier layer is spatially separated from the surface 43, so that it can not lead to abrasion of the carrier layer.
- the coating elements 2 On the outer surface of the coating elements 2, a certain proportion of the hard, advantageously spherical particles 22 is partially exposed. In this way, the rough surface 43 comes into contact mainly with the rounded, hard surface of the particles. Since these particles are harder than the rough surface, no or only a slight abrasion of the particles takes place. Only optionally exposed parts of the crosslinked polymer matrix are removed by abrasion, whereby, however, additional hard, near-surface particles are automatically exposed in part. The result is a Cefelteil which has a very high abrasion resistance.
- a breathable membrane at a suitable point.
- FIG. 4 (a) Such a possible embodiment is shown schematically in FIG. 4 (a). Between the carrier layer 1 1 and the second layer 1 2 a breathable membrane 1 3 is arranged.
- FIG. 4 (b) A further embodiment of a textile surface product according to the invention is shown in FIG. 4 (b), in which a further coating 14 is applied on the outside, which completely covers the carrier layer 11 and the coating elements 2 mounted thereon.
- a further coating 14 can consist, for example, of a foamed, flexible polymer layer 14, for example of a polyurethane polymer, which is applied to the carrier layer 11 after the application and curing of the coating elements 2.
- the outside is additionally provided with a further textile layer 1 5.
- Such an embodiment is advantageous, for example, if the coating elements should normally not be visible.
- a possible field of application are, for example, textiles for motorcyclists. Normally only the outer layer 1 5 is visible. In a fall, the outer layers 1 5, 1 4 are removed very quickly by abrasion. However, the underlying coating elements 2 prevent further penetration. The carrier remains protected.
- FIG. 4 (c) Another embodiment of a textile surface product according to the invention is shown in FIG. 4 (c).
- the carrier layer 1 1 Coating elements 2, 2 'attached.
- Such a textile surface product according to the invention offers the advantage that both sides can be used equally.
- FIG. 1 A possible example of such an arrangement of coating elements 2 is shown in FIG.
- a plurality of rectangular coating elements 2 are alternately arranged horizontally and vertically. The result is a pattern in which there is no straight line 42 that does not intersect a coating element 2. As a result, each sharp edge slides exclusively over the surface of the coating elements, and does not come into contact with the carrier layer 1 1 in the spaces 1 1 2.
- the carrier layer or optionally underlying further layers of the surface product can not be cut.
- the pattern shown in Figure 5 is just one of a variety of possible cut-resistant patterns. This can be optimized depending on the desired property. Basically, a higher number of coating elements leads to a greater cutting resistance, but also to an increasing stiffness of the textile surface product. coating material
- the coating material for coating the carrier layer of the inventive textile surface with the coating elements essentially comprises a polymer material and a filler in the form of hard particles, which ensure the abrasion resistance of the coating elements. There are also other ingredients for influencing the properties of the coating material.
- the major components of the coating material are the polymeric material and the filler.
- the fixed, preferably thermoset polymer must be able to hold the embedded fillers with sufficient strength so that they can absorb the high forces in use.
- the particles of the fillers must have the highest possible compressive strength and hardness so that they are as little damaged as possible during use.
- Thermosets have the particular advantage that they do not melt. Even with strong friction, the coating elements remain stable because they do not melt in the friction heat.
- liquid resin prepolymers are advantageously used, for example epoxy resins having a molecular weight ⁇ 700 g / mol. These can be cold-setting, heat-curing or UV-curing. When using liquid resins, less cratering occurs for physical reasons and the formation of Benard cells becomes impossible. In order to avoid pore formation in the interior of the material, which would adversely affect the mechanical stability of the fasteners, the coating material should be as free of air as possible.
- the liquid resin prepolymer is advantageously 1 00%, ie without solvent. This avoids the formation of pores by evaporating solvent, as well as a slow drying phase before the start of the crosslinking reaction.
- Suitable fillers are materials with hard inorganic / mineral or metallic particles. Particularly advantageous are hard, spherical particles, as used for example for sandblasting, especially since similar demands are placed on the material. Suitable examples are glass beads, ceramic beads and chilled cast beads.
- spherical particles An advantage of spherical particles is the low abrasion of the particles lying on the surface of the coating elements, since their spherical surface has less interaction with other surfaces during sliding friction, so that less force is absorbed by an object rubbing over the coating elements onto the particles.
- Another advantage of spherical filler particles over broken, edged filler particles is the peculiarity that spherical particles in dispersion less affect the viscosity.
- the optimum filler content depends on the nature of the filler itself and the polymer material as well as on the adjustment of the properties of the coating elements. For example, good results are achieved with 70% by weight proportion of filler in the overall mixture. At lower filler levels, the abrasion resistance decreases as more of the polymer matrix is exposed on the surface of the coating elements. At higher filler contents, the stability of the polymer matrix in which the particles are embedded decreases, which also leads to a decrease in abrasion resistance. In addition, the adhesion of the coating elements to the carrier layer of the inventive textile planar product decreases. For coating the carrier layer with the coating elements, a pasty coating material is advantageous. The paste batch is initially charged with the resin prepolymer.
- the additives for a better manufacturability of the Be Schweizerungsma- terials such as wetting agents and dispersants are added.
- optional additives such as dyes, additives for improving the long-term stability (light stabilizers, radical scavengers, etc.), and additives for additional functions are added.
- the fillers are dispersed in the paste. The addition of rheology additives takes place only at the end, so that the mixing of other ingredients can be easier.
- the rheology additives serve to adjust the viscosity of the coating material to a value suitable for the invention.
- a rheology additive it is advantageous to choose highly thixotropic types in order to keep the flow resistance in the delivery lines low and, at the same time, to achieve high stability of the coating elements applied to the carrier layer. An undesirable bleeding of the still uncured coating elements after the order is thus avoided.
- the high viscosity of the quiescent thixotropic paste has a lower sedimentation tendency.
- the addition of hardeners happens differently depending on the type. In the case of the cold-curing hardener types, the addition takes place shortly before production, whereby the pot life is to be observed. In the case of thermosetting hardeners, the addition can also be carried out as the first component in the resin. In UV-curable mixtures, UV initiator addition may also be the first component in the resin, but the paste should be strictly protected from exposure to light.
- Suitable parameters for a paste-like coating material are, for example, a viscosity of 80 to 200 d Pa.s, a filler fraction of 30 to 70% by weight, and a grain large of the filling material between 1 5 and 1 000 ⁇ , preferably ⁇ 1 50 ⁇ .
- Suitable liquid resins are bisphenol A resins and aliphatic epoxy resins.
- the coating material is cold-setting, heat-curing or UV-curing, is not directly relevant to the invention, but must be tailored to the specific design of the coating process.
- composition of the coating material should be chosen so that the lowest possible curing time is necessary and the lowest possible exothermic occurs. Hardening times should be within the scope of normal textile finishing processes. Too much exotherm during curing would lead to a strong local increase in temperature, which could damage the carrier layer.
- the cured coating elements should also preferably have high resistance to solvents, fuels, acids and alkalis.
- additives for functional scratch resistance e.g. through paraffin
- UV enhancement absorber e.g. Benzotriazole derivatives
- Radical scavengers e.g. HALS connections as needed
- Additional radio accessories e.g. Flame retardants such as expandable graphite;
- rheology additive e.g. Hydrophobic silicic acid
- additives for functional scratch resistance e.g. through paraffin
- UV enhancement absorber e.g. Benzotriazole derivatives
- Radical scavengers e.g. HALS connections as needed
- Additional radio accessories e.g. Flame retardants such as expandable graphite;
- rheology additive e.g. Hydrophobic silicic acid
- Temperature-activated crosslinkers e.g. Di-cyandiamide derivatives
- Temperature-activated crosslinkers triglycidyl isocyanurate (TCIC)
- the textile surface to be coated is advantageously rendered hydrophobic, at least temporarily, in order to prevent excessive sinking of the paste. This can be done for example by impregnation or a one-sided coating, for example with a fluorocarbon finish.
- a stencil printing method is advantageously used, for example by means of rotary stencils or flat stencils.
- the wall thickness of the templates is advantageously between 0.5 and 4 mm.
- the printed area should be between 30 and 70% of the total area of the carrier layer. The higher the degree of coverage, the more the textile feel is influenced.
- the stencils lie on the carrier layer to be coated, the paste is placed on the stencil and doctored off.
- the paste is removed from the template surface and remains in the openings.
- the coating elements remain adhered to the carrier layer.
- the amount of coating material to be applied varies depending on the property to be achieved of the inventive textile surface product, and is about 1 00 to 1 500 g / m 2 , preferably from 1 00 to 600 g / m 2 .
- the paste penetrates even before curing superficially in the textile, wherein after curing by positive engagement of the crosslinked polymer matrix with the structure of the support layer a very strong, mechanical anchoring of the coating elements on the support layer and thus a high adhesion.
- the coating elements are cured, that is, the crosslinking reaction of the thermosetting prepolymer mixture is started. There is no drying necessary because preferably no solvents are included in the paste.
- the curing conditions are to be adapted to the resin systems used. If temperature-activated crosslinkers are used or if it is a self-crosslinking binder system, then a specific reaction to the application of the coating elements must take place. be reached onstemperatur. The typical parameters are as follows: Cold curing mixtures: 1 20-200 ° C; hot-curing mixtures: 1 50-200 ° C.
- the carrier layer with the coating elements is irradiated with UV light in order to start the crosslinking reaction.
- No temperature increase is necessary for the curing, however, a thermal post-curing is possible at 1 50 to 200 ° C.
- the coating elements must be at least sufficiently hardened that they no longer stick and have sufficient strength, and that they can not smudge, smudge or otherwise be destroyed in any way.
- the carrier layer can be rolled up or stacked, or fed directly to a further processing to the finished textile sheet product, for example by further layers are applied.
- the coating material can then be postcrosslinked, if necessary by renewed temperature treatment. However, the resins used partially also react at room temperature until fully cured.
