  • the thickness of the rubber layer is selected so as to surround the implanted fibres over about one-tliird of their length.
  • the manufacturing process which is also A ⁇ to the backing fabric so that friction or folding can not result in dragging away the fibres.. ⁇ Due to the fact that the fibres cross through the rubber layer without being ineness of these channels prevent water from flowing through and their very large quantity (the fibres density can reach and even exceed 40,000 per square centimeter) allows a free passing of the air.
  • This air permeability permits use of the fabric according to the invention for invention will confer elasticity, feeL strength and the 4look of a velvet fabric, leather or a high grade skin.
  • Fig. l is a diagrammatic side elevational view of apparatus for applying an anchoring layer and the Hock to a fabric backing.
  • the strip of backing fabric 10 is continuously fitted
  • the strip is driven, in a known way over rotating cylinders 11 and the layer of rubber is spread on its upper face by means of a doctor-blade 12 and of the rubber layer 22 (Fig. 2).
  • the fabric is moved into a tunnel dryer 21 having a temperature of about C., in which the rubber is cured in a few minutes.
  • the layer consists many, a suiicient throughfare for the air. then dried. A new layer of rubber is spread over it, the
  • fibres are implanted in this last layer and the whole is cured, the adhesiveness between the two layers with a foundation of rubber resulting in the formation of a very solid flock fabric.
  • the granular adhesive product according to the second embodiment for the intermediate adhesive layer spread on the backing fabric is constituted by an aqueous paste of a body containing some synthetic or natural rubber, coagulated but non cured, in the form of thin and fairly spherical particles, resembling fish eggs.
  • the process, according to the invention, of preparing the granular paste above described consists in preparing a foam with a crude natural or synthetic rubber, foam ⁇ at a temperature lower than the cure temperature and crushing it to obtain substantially spherical particles, of a size of about .0l to 0.15 millimeter.
  • the adhesive paste according to the invention is made preferably of latex. formation, or autovulcanization, of the latex coagulated in the shape of granules, it is advisable to add to the mixture a given amount ofl gutta-percha.
  • gutta-percha To this gutta-percha are first added about of stearic acid and of sodium oleate. The mixture is subjected to a strong mastication between cylinders heated at about 60 C. After cooling, the mixture is crushed anew in the cold state and the resulting fragments are treated during one hour, at 165 C., with hot air in a closed chamber, this thermic treatment being intended to soften the gutta-percha and to make it absorb water. The mixture is then kneaded with hot water, giving a paste which can be mixed with the latex.
  • the latex granules are embedded in a sheltering film 0f Turkey redoil mixed with the product at a rate of about 1.5% and which, when used, will emulsify very easily with the thinning water.
  • This adhesive granular paste is spread on the fabric in a known way, for instance by means of a doctor blade spreading the paste over the fabric which is driven through the machine at a speed of 2 meters per minute for instance.
  • the thickness of the paste layer should preferably be about 0.15 millimeter.
  • the machine is slightly heated.
  • the coated fabric is dried and afterwards coated with drying this f
  • the appearance of the finished fabric may be varied by employing fibers of various type such as rayon, cotton, wool, and the like.
  • the length of the fibers may also be varied between 0.5 and 5 millimeters.
  • the thickness of the rubber layer or layers may be varied'accordingly.
