Definitions

  • floor covering materials comprising a substrate and an upper layer, consisting, respectively, of a fabric and a more or less wear- resistant material
  • linoleum is manufactured from a substrate consisting of jute fabric, on which a hot plastic mass of oxidised and gelated linseed oil, fillers and dyes and, as the case may be, further additives, is calendered.
  • the web thus obtained is introduced into a drying chamber in which it is suspended in loops, and the upper layer is allowed to set therein. After leaving the drying chamber, the web is cut to the required size, and is wound on rolls.
  • the threads of the substrate should withstand the forces exerted thereon in the longitudinal direction of the web during calendering and also during setting. These forces may give rise to more or less elastic deformations in the fabric and in the upper layer fixed thereon, which will partly be restored after setting of the upper layer.
  • the linoleum shows a more or less elastomeric behaviour, which means that on deformation the total volume will not or not substantially change, so that a reduction of the length in one direction will lead to an increase of the length in a different direction and vice versa.
  • the restoration of a deformation after disappearance of the forces causing said deformation can occur with a certain delay, and is not necessarily complete.
  • the jute fabric and also the upper layer material are sensitive for moisture which may also lead to changes of dimension which cannot be controlled. A consequence of all this is that linoleum is not dimensionally stable, which also holds for other materials with a comparable behaviour.
  • a substrate which is less sensitive for moisture than jute and which can better resist to increases of length might, probably, improve the insufficient dimensional stability of linoleum and similar floor coverings.
  • Glass fibre fabrics will, as such, satisfy this requirement, but the longitudinal threads thereof can often not withstand the longitudinal forces occurring during calendering, so that rupture can occur then.
  • the invention is based on the insight that use can be made of the elastomeric behaviour of the upper layer material for improving the dimensional stability.
  • the invention comprises a floor covering consisting of sheet material comprising a fabric substrate with threads in the longitudinal and transversal direction respectively of said sheet, and an upper layer of an elastomeric and wear-proof material adhered to said substrate, characterised in that the transversal threads of said fabric have a larger elasticity modulus than the longitudinal threads, the latter having a sufficient tensile strength for withstanding the longitudinal forces occurring during manufacturing.
  • the fabric threads extending in the longitudinal direction ensure the integrity of the formed material during calendering and setting, and can undergo a certain stretch, which, after disappearance of the generating forces, has a tendency of recovering.
  • the upper layer material will, after setting and after disappearance of the longitudinal forces, try to shrink somewhat. Shrinkage in the longitudinal direction would lead to an increase of the transversal dimension which will be opposed by the transversal threads which had not been loaded during calendering and setting, so that shrinkage in the longitudinal direction is, therefore, counteracted. In this manner a very good dimensional stability can be obtained.
  • transversal threads of such a substrate fabric consist, in particular, of glass fibres, and the longitudinal threads can consist of a polyester.
  • Such a web is particular suitable for being cut into tiles, as the tiles have now become sufficiently dimensionally stable, so that during storage no substantial dimensional deviations will occur which would reduce the usefulness of the tiles.
  • the substrate shown consists of an open fabric with threads or bands 1 of glass fibres directed in the transversal direction of the web, and having a large elasticity modulus which means that, on stretching said threads, very considerable tensions will occur, so that a high resistance against stretching will be obtained.
  • Such fibres have a relatively low stretch at rupture.
  • the web threads or bands 2 consisting of a polyester are provided. These threads have a lower elasticity modulus so that less resistance against stretching will be provided. The tensile strength of these threads should, however, be sufficient for withstanding the forces occurring during manufacturing.
  • the cover layer material calendered on the fabric intrudes into the interspaces 3 between the fabric threads 1 and 2, and adheres to said threads. After completion of setting of the material and disappearance of the longitudinal loads, however, a tendency to shrink will occur, but the cover layer material shows, in linoleum or similar floor coverings, to a substantial degree an elastomeric character, which means that on deformation the total volume will remain substantially unchanged. This means, furthermore, that when longitudinal shrinkage will occur, this should be accompanied by a lateral expansion. This expansion, however, is opposed by the glass fibre threads 1, so that a substantial longitudinal shrinkage cannot take place either.
  • the polyester threads 2 remain, therefore, subjected to a certain tension, and also in the upper layer tensions will remain.
  • the current linoleum with a jute substrate is sensitive for moisture.
  • the filler substances present in the upper layer such as sawdust or the like, can absorb moisture, and also the jute fibres are moisture sensitive. All this will be expressed in a rather substantial increase in width, but also a certain longitudinal shrinkage appears to occur. The total volume may slightly increase when absorbing moisture.
  • the upper layer is equal to that of the known linoleum, and is, therefore, moisture sensitive.
  • the increase in width is prevented for the greater part by the glass fibres.
  • the expansion should, therefore, take place primarily in the longitudinal direction, and then the tendency to shrink in that direction is to be overcome first, but also the prestressing to which the polyester threads are submitted. It has appeared to be possible to obtain substantially equal expansions in both directions.
  • a part of the expansion can, moreover, express itself as an increase in thickness. If square tiles are cut from such a floor covering, said tiles will remain substantially square even when absorbing moisture, so that laying such tiles in specific patterns, in particular with alternating directions, remains possible.
  • the adhesion of the upper layer material and/or of a glue used for fixing the floor covering to an underlying floor can be improved, and, as the case may be, also the moisture sensitivity can be reduced thereby.
  • the invention is not restricted to a fabric of glass fibre and polyester threads, and that also other kinds of threads can be used, provided that the latter will be able to provide a sufficient transversal resistance against stretching and are longitudinally sufficiently strong and yieldable for being able to withstand the occurring forces.
  • the invention is, moreover, not restricted to linoleum, but can also be applied with other floor coverings showing a certain elastomeric behaviour.
