Definitions
- the invention relates to a spacer fabric with an upper and lower fabric, between which intersecting support threads are arranged, which hold the upper and lower textiles spaced apart from each other and a method for its production.
- Spacer knitted fabrics are produced from an upper textile and a lower textile, which are kept apart by supporting threads, in particular monofilaments.
- the support threads or monofilaments are plastic materials and usually consist of one strand.
- the compression hardness of the spacer knitted fabric is determined.
- Spacer knits are used, for example, as a seat pad for wheelchairs or as a sleeping pad for pressure ulcer patients.
- Conventional spacer fabrics have the disadvantage that they can absorb only very limited shear forces and that they have limited ability to keep the textiles spaced from each other.
- the object of the present invention is to provide a spacer knit and a method for its production, with which a better shear and compressive strength of the spacer knitted fabric can be achieved.
- the spacer fabric according to the invention provides an upper and lower fabric, between which intersecting support threads are arranged, which keep the upper and lower fabrics spaced apart and held together. At least parts of the supporting threads are connected to one another at their points of intersection, which results in an increased shear strength of the entire spacer fabric and an increased resistance to bending. be provided against the compression of the textiles towards each other. As a result, the finished spacer fabric can not be completely compressed or only compressed against an increased compressive force, since the intersecting support or spacer threads are connected to each other at certain points, comparable to welded wires in a chain link fence. Depending on the density and the crossing angle of the supporting threads as well as the number and arrangement of the connections in the crossing points, the hardness of the spacer knitted fabric can be adjusted.
- the support threads are formed as monofilaments, twisted support threads or core-shell spuns.
- the support threads can be coated or sheathed, such as monofilaments, core-shell-puffs or twisted support threads, in order to facilitate or facilitate the connection of a plurality of support threads to one another at their points of intersection.
- the coating or sheath may be made of a plastic or an adhesive having a lower activation temperature than the core of the support thread.
- the support threads themselves can have different diameters, whether by coating with a plastic or an adhesive, or that the desired compressive strength and shear stability should be set by a suitable choice of the support thread dimensioning.
- the inventive method for producing a spacer fabric provides that at least parts of the intersecting support threads, which connect an upper textile and a sub-textile spaced apart from each other, are joined together at their intersection points. It is envisaged that the support threads are glued or welded together.
- the coating, sheathing or wrapping is such that the melting point is lower than that of the core and that the spacer fabric is at a temperature below the melting point of the core Kerns and above the melting point of the coating, sheathing or wrapping is heated.
- the adhesive is activated or the plastic coatings are melted, so that it comes to a non-positive or cohesive connection between two intersecting support threads.
- a thermal bond can also be a chemical bond by dissolution and curing of the coating, sheathing or wrapping done.
- uncoated support threads can also be connected to one another by a thermal or chemical bond by melting or dissolving only part of the support thread and then curing them.
- the spacer fabric After connecting the support threads by heating to a predetermined temperature, it is provided that the spacer fabric is kept at a temperature below the melting or activation temperature in order to reduce adjusting deformations and stresses within the spacer fabric.
- Figure 1 - a conventional spacer fabric; such as
- Figure 2 an inventive spacer fabric.
- FIG. 1 shows a spacer fabric 1 with a top textile 2 and a bottom textile 3. Between the textiles 2, 3 support threads 4 are arranged, which intersect and are attached to the textiles 2, 3 in a certain bond and density. The support threads 4 are not connected to each other, so that the compression hardness, ie the resistance to a load perpendicular to the textile plane, by the diameter of the support threads 4, the binding of the support threads 4 to the textiles 2, 3, the density of the support threads 4 in the finished product and the crossing angle of the supporting threads 4 can be determined.
- the compression hardness ie the resistance to a load perpendicular to the textile plane
- connection levels 6 in the illustrated embodiment, these are two levels, can be compressed under load or partially fail, so that connection points 5 dissolve and the compression would take place up to the second level 6.
- connection levels 6 For longer support threads 4 or a corresponding density and selection of the crossing angle even more connection levels 6 can be created.
- a limited and predetermined number of support threads 4 and monofilaments is provided with a coating and an adhesive.
- e.g. evenly distributed provides increased resistance to crushing or shearing motion in the spacer fabric.
- load-resistant resistors in a spacer fabric in order, for example, to achieve a uniform support of the entire body in decubitus patients.
- the finished spacer fabric 1 After bonding by heating, it is provided to keep the finished spacer fabric 1 at an elevated temperature below the activation or melting temperature of the coating, in order to be able to reduce stresses present within the spacer fabric 1.
