Definitions

  • the present invention relates to a CV flooring comprising a nonwoven fabric as a structural layer. It further relates to a nonwoven fabric.
  • CV (Cushioned Vinyl) floor coverings are known.
  • fiber webs are used as a carrier material.
  • the fiber webs used here are typically made of glass fibers, whereby the use of specific mixtures of different glass fibers for the production of corresponding carrier glass fiber webs is known (see. DE 102011011056 A1 whose disclosure is included in the content of the present application).
  • DE 102011011056 A1 whose disclosure is included in the content of the present application.
  • a nonwoven fabric namely a hybrid nonwoven fabric comprising a base web having 10-80 wt.% glass fibers and 20-90 wt.% PET fibers.
  • polyvinyl alcohol is provided in an amount of 5-35% by weight based on the combined weight of the glass fibers and the PET fibers as a binder.
  • a secondary binder is provided in an amount of 5-35% by weight based on the combined weight of the glass fibers, the PET fibers and the polyvinyl alcohol.
  • the secondary binder may be, for example, styrene-acrylate.
  • the glass fibers preferably have a mean diameter between 6 and 16 ⁇ m and an average length between 4 and 25 mm.
  • the PET fibers likewise preferably have an average diameter of between 6 and 16 ⁇ m and an average length of between 4 and 25 mm.
  • the present invention is directed to providing a nonwoven fabric which can be produced cost-effectively and which is particularly suitable for use as a carrier material in floor coverings and thus has a favorable influence on the properties of the finished floor covering. Furthermore, it is an object of the present invention to provide a correspondingly favorable properties having CV floor covering with a nonwoven fabric as a carrier material.
  • a nonwoven which is designed as a hybrid nonwoven fabric by comprising glass fibers, polymer fibers and binder, wherein the glass fibers have an average diameter between 6 and 13 .mu.m and a
  • the polymer fibers are staple fibers having an average fineness between 0.2 and 0.6 dtex and an average length between 2 and 4 mm, and the weight fraction of the polymer fibers is between 5 and 20% of the dry nonwoven fabric ,
  • a specific combination of synergistically interacting features is characteristic of the nonwoven fabric according to the present invention in that it consists of relatively short fibers interconnected by a binder both in terms of material and in typical length and thickness dimensions -
  • the proportion by weight of the polymer fibers being substantially lower than that Weight fraction of glass fibers in that the polymer fibers make up only between 5 and 20, preferably between 10 and 15 percent by weight of the dry fiber web.
  • the ratio between the weight fraction of the glass fibers and that of the polymer fibers to the fibrous web is typically between 5 and 8, for example - at a weight fraction of the binder of between about 20 and 30% - about 6.5.
  • the hybrid nonwoven fabric according to the invention is characterized by a number of very advantageous for use as a support material in CV floor coverings properties.
  • such physical properties mechanical strength, density, pore volume, void structure, etc.
  • already particularly thin hybrid fiber webs according to the invention fulfill the requirements applicable to structural materials of floor coverings.
  • This is therefore a not to be underestimated advantage, because in this way (already due to the reduced thickness of the nonwoven fabric), the amount of impregnating agent with which the nonwoven fabric is to be treated, can be reduced.
  • the non-woven fabric according to the invention even has a surface structure of special quality and homogeneity, so that even a flooring produced using it is characterized by a special surface quality. This is an invaluable advantage for a surface finish, especially through printing.
  • the present invention provides excellent nonwoven fabrics in terms of their properties, namely, for example, by avoiding additional fiber coating disadvantageous in terms of material and processing costs, with minimal effort and without the use of health hazardous respirable micro-glass fibers.
  • the polymer fibers consist of a polymer having a density between about 1.2 and 1.6 g / cm 3 . It is particularly favorable if the polymer fibers consist entirely or at least predominantly of PET (polyethylene terephthalate). Because when using such a material for the production of polymer fibers, the latter have such properties that are suitable for the nonwoven fabric process, to which there are empirical values from the production of pure glass fiber webs.
  • the hybrid nonwoven fabric according to the invention is prepared by passing the glass fibers and the polymer fibers containing water in circulation through a belt filter, the fiber mixture thereby deposited in the form of a fiber layer with a predetermined layer thickness on the belt screen Excess circulating water is removed from the fibrous layer, the fibrous layer is mixed with binder and the binder-added fibrous layer is dried.
  • the particular advantages of the glass fiber fleece according to the invention set out above are particularly pronounced if the mean fineness of the polymer fibers is between 0.3 and 0.4 dtex. Excellent results can be achieved, for example, when using PET fibers with a fineness of 0.33 dtex and a mean length between 2.5 and 3.5 mm.
  • the mean fiber diameter of the glass fibers is between 7 and 10 ⁇ m and / or the mean length of the glass fibers is between 7 and 9 mm.
  • the glass fibers are not longer than 15 mm and not thicker than 10 ⁇ m; because at dimensions above these values, the surface properties of the hybrid nonwoven fabric deteriorate.
  • the glass fibers consist of C glass and / or E glass.
  • the basis weight of the glass fiber fleece is between 25 and 80 g / m 2 , more preferably between 40 and 60 g / m 2 . Again, this results in very particularly advantageous properties of the hybrid nonwoven fabric according to the invention in the In view of its use as a substrate in CV floorings having excellent properties.
  • the binder comprises urea resin or polyacrylic acid binder.
  • the binder may also include polyacrylic acid.
  • Outstanding properties result when the binder comprises a mixture of urea resin and polymer dispersion or a mixture of polyacrylic acid binder and polymer dispersion.
  • the binder may contain an additive (or additives) which may account for up to 50% of the total weight of the binder.
  • the additive (or the additives) can thereby the properties of the binder with regard to the individual Specifically modify or optimize the determination of the hybrid fiber fleece.
  • Typical additives include kaolin and TiO 2 .
  • additives can not only technically optimize the binder, but additives are also useful in reducing costs by reducing the need for expensive binders.
  • the present invention relates to the above statements equally on the untreated hybrid nonwoven fabric, on a pretreated for further processing to a CV flooring, in particular provided with an additional impregnation hybrid nonwoven fabric, wherein the impregnating agent in particular plastisol or another PVC-based agent, as well as on the finished CV flooring produced using the hybrid nonwoven fabric according to the invention, which comprises a wear layer and a structural layer, wherein the structural layer comprises an impregnated hybrid nonwoven fabric according to the invention (see above).
  • hybrid nonwoven fabric according to the invention in the production of CV floor coverings is in the foreground, which concerns the particular suitability of the hybrid nonwoven fabric according to the invention, various aspects of the hybrid fiber nonwoven according to the invention set out above make this possibly also for others Applications can be used with particular advantage.
