Definitions
- the invention relates to a textile sliding surface for ski and toboggan use, which comprises a base layer and a functional layer and thus forms a mat.
- This mat has snow-like sliding properties on the surface of the functional layer.
- the structure of the functional layer in the application ski offers largely uniform guidance properties and thus enables use with various winter sports equipment, such as skis, snowboards, etc.
- the trapability and closed surface with a low loop height in the functional layer enables use for tobogganing at turns.
- the sliding surface enables these applications all year round and therefore independent of snow and temperature.
- DE 102013 014285 describes a layer composite with a sliding surface.
- the sliding layer consists of floating warp threads with a floating length of 3-100mm.
- the warp threads can be so close together that an almost closed surface is created as a sliding surface.
- the ridges and grooves created by the float have a width dimension, transverse to the direction of travel, of 2-5mm.
- the warp threads themselves have an outside diameter of 1-6mm.
- the disadvantage has arisen that the properties of the sliding surface, especially in the edge behavior of the ski, are direction-dependent.
- This directional dependency results from the small number of pile loops which are in the Usually formed with a multifilament in order to increase the proportion of the material on the surface and thus the wear volume.
- the hold of the edge of the ski depends on the angle at which the sliding surface is passed. This manifests itself in the fact that the turn initiation is not possible in a drifting style of skiing with little relief of the ski (especially the outer ski). The edge hold is therefore too great here.
- This behavior is reversed in the further course of the curve control. Then the edge hold decreases and the outer ski slips away. A similar behavior can be observed in the carving.
- the edge properties that are always the same from the snow are therefore not available. This makes it especially difficult for beginners to drive on.
- the yarn made of mono- or multifilaments extends on the surface of the mat for about 10mm between the two attachment points in the base layer. If this lying flat yarn (loop height 0mm) is destroyed by external influences in the middle of the yarn, two open ends of the yarn are created which, due to their continued attachment in the base layer and the associated tension, protrude slightly upwards. In practice, an angle of around 20-40 ° standing up was observed. The open, destroyed ends of the yarn protrude from the actual surface of the mat and form a sharp edge with an increased risk of injury.
- connection technology to connect individual modules of the mats directly in the product (e.g. through overlapping points, fastening points)
- the present invention is therefore based on the object of meeting these requirements and thereby ensuring inexpensive production and laying of the mats.
- edge and guidance properties are independent of the laying or direction of travel due to the high number of poles and the low floating.
- the large number of small pile loops enables even edge guidance and at the same time a soft and fall-proof surface.
- the uniform edge guidance is achieved by the large number of smaller pile loops. These smaller pile loops are made from a monofilament yarn compared to multifilament yarn. This increases the number of contact points with the ski while maintaining the same wear volume on the surface. The higher number of pile loops also enables a more uniform distribution of the pile loops on the mat. This means that, regardless of the angle of the ski in relation to the direction of travel, there is always almost the same number of pole loops in engagement with the ski. In the Turn initiation and turn control, no differences can be determined in the force that the mat exerts on the ski.
- connection of the individual mats to form larger areas can be done directly via features contained in the material.
- the loop height can be adapted in such a way that a closed surface with the same pile height is created even if there is overlap, for example.
- Figure 1 is a schematic cross section of the mat
- Figure 2 is a plan view of the mat
- Figure 3 is a schematic cross section of the junction between the mats.
- the textile in a mat consists of a functional layer 1 and a base layer 2
- the functional layer 1 structurally has one or more pile loops 3 made of a fiber or filament yarn made of chemical fiber materials. These yarns are optimized for the friction pairing with the PE lining of the ski. It becomes so a snow-like coefficient of friction (also called coefficient of friction) of ⁇ 0.1 is achieved.
- a plastic based on PET polyethylene terephthalate
- Other plastics with optimized sliding properties for example based on the plastics PBT (polybutylene terephthalate), PP (polypropylene) or PA (polyamide), can also be used.
- the base layer 2 also comprises a textile material and forms a dense fabric (for example by a rep weave), which carries the functional layer 1 and by clamping or tying in (between the warp, binding and weft threads) by form-fitting the pile loops stabilized.
- a W-binding 10 is used, which prevents the pile loops of the functional layer from tilting to the side due to a further small loop or deflection in the base fabric (W-shaped course of the pile yarn).
- the pile loops of the functional layer 2 can be designed with a loop height 4 of 0.5mm to 4mm (mainly toboggan use) or 4mm to 14mm (ski use) in order to meet the sport-specific requirements. The higher the requirements for edge hold on alpine and cross-country skis, the higher the pole loops should be. Low pile loops are an advantage for tobogganing at turns.
- a variation of the loop heights 4 is possible both in the longitudinal 5 and in the transverse direction 6 of the textile.
- the distances between the pile loops (7 & 8) for pattern formation on the surface can also be varied between 1.5mm and 20mm. This creates a loop density of 400-1200 pile loops / dm 2 , for tobogganing at turns even up to 2400 pile loops / dm 2 .
- the material thickness of the pile yarn in the pile loops is 0.5-1.2mm.
- Yarns of different strengths can be used alternately.
- the continuous use of yarn with a thickness of 0.7mm has proven to be optimal.
- a mixture of 1/5 monofilament yarn with a high thickness (strength) in the range 0.9-1.2mm and 4/5 monofilament yarn with a small thickness 0.5-0.7mm is used.
- a new production method makes it possible to produce the multitude of parameters and product properties in one production step. This eliminates the need to rework the fabric known from previous products in order to achieve the desired functions.
- the possibilities of the machine with regard to fast setting of loop height, loop density and pattern, as well as their variation within a product, are optimally used.
- Mats can be prepared up to 4m. There is only one limitation in the length of the mat due to transport.
- the weaving technique enables the production of the complete mat including connection features in one work step.
- only the individual yarns for the fabric are used as the starting material. These can be applied directly to a machine and woven into a mat. Both the base layer 2 and the pile loops 4 of the functional layer 1 are thereby formed.
- the material of the base layer 2 is mainly unwound from warp beams.
- the material of the functional layer 1 is preferably obtained from individual coils for easier patterning and adaptation of the material properties. An entry of several shots on top of one another is possible and thus creates the possibility of a greater variety of products and integration of properties compared to previously known products, since the layer structure of the base layer 2 is significantly more variable. No further intermediate steps or production steps in preparation or follow-up are necessary for the production of the mat including all properties.
- the mat comprises a base fabric 2 based on polypropylene fibers, which as binding and filling warp threads, as well as weft threads for Use.
- the functional layer 1 is a pile fabric made of a monofilament yarn made of 100% PET with the following construction parameters:
- the mat is used for the ski school application.
- An underlay which is placed under the mat to protect against damage and for better drainage, consists of a layered composite of nonwovens and random plastic layers.
- the overlapping mats are attached using a sheet metal that is anchored to the ground with ground screws.
- Self-tapping self-tapping self-tapping screws are screwed into the sheet metal through the overlap point 11 of the mats in such a way that the screw heads are well below the surface of the mat and therefore have no influence on winter sports equipment.
- the mat also comprises a base fabric based on polypropylene fibers.
- the functional layer 2 is a pile fabric made of monofilament yarn made of 100% PET with the following construction parameters:
- Loop density 500 pile loops / dm 2
- the mat is used for professional training in skiing. For example, the mat is screwed directly onto a wooden substructure. In this way, you can screw directly into the base material through the overlap point of the mats. A connection via a sewn-on Velcro tape or an attached magnetic solution is also conceivable.
- the mat comprises a base fabric 2 based on polypropylene fibers.
- the functional layer 1 is a pile fabric made of monofilament yarn made of 100% PET with the following construction parameters: Yarn thickness (9): 0.7 mm
- the mat is used as a toboggan run or run-up track for skis with a separate guide bar, the good trapability of the textile in the mat is used to let this in the form of a guided bobsleigh run and with the same surface both the To form the sliding surface as well as the gang.
- a similar principle is used when used as a classic cross-country ski run.
