Definitions

  • the invention relates to a painting to be based on vegetable fibers intended to be applied as a wall covering of buildings, especially for residential use.
  • Nonwovens are easy to apply and are inexpensive. Their function is essentially decorative: the diversity of structural patterns that can be obtained is very large and in general the nonwovens do not require any treatment after the application such as the application of a paint. However, they do not resist abrasion well and they participate very little in strengthening the support on which they are applied.
  • Tissues of natural fibers of plant or animal origin are usually laminated on a paper support which is then glued to the wall, or hung on rods attached to the periphery of the walls.
  • Glass fabrics are particularly advantageous. They have excellent mechanical properties, including high abrasion resistance and high tensile strength which enable them to perform the function of reinforcing material of the support to which they are applied. Glass fabrics are also rotproof and incombustible.
  • the object of the present invention is to propose a painting fabric which has superior mechanical properties to those of non-coatings.
  • woven fabrics including improved tensile strength and water resistance approaching those of glass painting fabrics, and which does not cause skin irritation.
  • the present invention provides a painting fabric consisting of a fabric comprising vegetable fibers, said fabric being coated with a primer.
  • Primer means the product resulting from the drying of a primer composition in the form of an aqueous solution of constituents capable of giving the fabric properties specific to the intended use.
  • the primer ensures the binding of plant fibers, gives flexibility to the canvas to be painted and improves its resistance to abrasion.
  • the painting fabric according to the invention consists of a fabric according to claim 1 and obtained from yarns composed of a multitude of vegetable fibers (or base yarn) or derived from these yarns, especially the assemblies of these fibers. base wires of wires of higher linear density.
  • the aforementioned son are composed of flax fibers, jute, ramie and / or cisal, preferably flax and / or jute and preferably flax.
  • Yarns consisting of fibers from a single plant are preferred.
  • the aforementioned son may be son without torsion or twisted son.
  • the fabric comprises, in warp, a twisted yarn (textile thread) and, as a weft, a non-twisted yarn generally in the form of a ribbon which may have undergone a treatment aimed at separating the vegetable fibers so as to give them volume (or "voluminized” thread).
  • the linear density of the warp and weft threads varies from 50 to 500 tex, preferably 100 to 350 tex.
  • the fabric may optionally contain fibers made of another material, in particular glass fibers, advantageously in the form of textile threads arranged in a chain.
  • the glass used in the constitution of the son can be of any type, for example E, C, R, AR (alkali-resistant), preferably E.
  • the fabric contains only plant fibers, preferably flax, jute, ramie and / or cisal, more particularly flax and / or jute and more preferably flax.
  • the diameter of the glass filaments constituting the wires may vary to a large extent, for example 5 to 30 ⁇ m.
  • the linear density of the glass yarn is identical to that of the vegetable fiber yarns.
  • the fabric may have plain, twill or satin weave.
  • the fabric used in the constitution of the painting fabric has a weight per unit area which varies from 30 to 1000 g / m 2 , preferably from 50 to 300 g / m 2 and advantageously from 75 to 200 g / m 2 .
  • the painting fabric comprises a primer which holds the yarns of the fabric, obscures the pores and gives it the proper rigidity so that the laying on the final support can be carried out properly.
  • the primer is present on both sides of the canvas to be painted.
  • the starchy compound is a starch, advantageously consisting of more than 50% by weight of a starch soluble in cold water, that is to say at a temperature of 20 to 25 ° C.
  • the soluble starch is a starch which has been chemically modified to give it the desired solubility.
  • the acrylic polymer is a homopolymer or copolymer of (meth) acrylic acid or alkyl (meth) acrylate, preferably a stryrene-acid (meth) acrylic or alkyl (meth) acrylate copolymer. acrylonitrile.
  • the primer may further contain conventional additives, such as a mineral filler (including a pigment), a foaming agent, a foam stabilizer, a softener, a thickening agent, an optical brightener and a biocidal agent and / or or fungicide.
  • a mineral filler including a pigment
  • a foaming agent including a pigment
  • a foam stabilizer including a foam
  • a softener including a foam, a foam stabilizer, a softener, a thickening agent
  • an optical brightener and a biocidal agent and / or or fungicide.
  • the inorganic filler is titanium oxide, calcium carbonate and mixtures thereof, and more preferably titanium oxide for its advantageous white color.
  • the foaming agent is an amine oxide.
  • the painting fabric may comprise an additional layer consisting of a water reactivatable glue on its back side (face which in the final disposition is glued to the support). Such a layer allows the operator, by simply applying water on the coated side, to reactivate the glued face and to lay the canvas directly on the support.
  • the manufacture of the painting fabric according to the invention can be carried out in a conventional installation which is suitable for the manufacture of glass painting fabrics, for example described in WO 2010/070248 .

  • the amount of the deposited primer composition is controlled by the distance between the two rolls.
  • the application device for the primer composition may also consist of two rollers each having a central tubing for feeding the pressurized primer composition.
  • the peripheral zone of the rollers is provided with perforations through which the primer composition which is deposited on the canvas to be painted passes.
  • This device distributes the primer composition on both sides of the canvas to be painted.
  • the application using this device is called "screen-to-screen" in English.
  • the drying device of the painting fabric may consist of a series of several rollers heated to an identical temperature or at different temperatures, in particular the first roll being heated to a temperature higher than that of the last roll.
  • the temperature to be applied at the level of the first roll is at most equal to 290 ° C.
  • the temperature of the roll must also be adapted according to the speed of travel of the painting on this roll. It is important that the temperature measured at the level of the canvas to be painted does not exceed 250 ° C so as not to damage the plant fibers.
  • drying devices may be used, for example devices delivering hot air or operating by infrared radiation.
  • the tensile strength of the vegetable fiber and glass fabrics in the machine direction (warp direction) and in the transverse direction (weft direction) are measured under the conditions of the NF EN ISO13934-1 standard.
