  • cream latex that is latex which is concentrated to about 60 percent by weight of solids
  • revertex which is concentrated to amply '70 percent by weight of solids
  • Latices containing more water, such as latex with about 38-40 percent by weight of solids will give a pap that is too thin for some objects if the ratio of solids in the pap is wanted to bemaintained.
  • Natural rubber latex as well as synthetic latices can be used.
  • the latices may contain self .vulcanizing agents and accelerators.
  • Example 1 125 parts by weight of cream latex containing stabilizer, anti-oxidant and preservator is added under stirring to the pap obtained accordingly to the preceding Example 1.

  • Figs. 5 to 8 correspond to Figs. 1 to 4 respectively and show the coverings thereof provided with a relief 4.
  • Fillers may be added to increase the hardness of the products manufactured with the pap.
  • Very suitable for this purpose is, for example chalk, of which according to the desired increase of the hardness, more or less is added (for example 125-300 parts by weight), mixed with water in a ratio that is dependent i. e. on the filler quality.
  • the ratio lies mostly at about 1:1. The most uniformdistribution is obtained by adding these fillers to the glue dispersion, i. e. prior to the addition of the fibre mass.
  • Still harder products can be obtained by incorporation of gyps (plaster), cement or similar fast-hardening materials, for example 100 parts by weight in 50 parts of water.

  • Pigments maybe added to any of the components of the pap," or to the semi-manufactured or final product.
  • Preferably latex dye is used for this purpose as only a small quantity thereof is necessary thanks to its strong colouring power.
  • the products obtained from the pap are poorly inflammable, it can be useful in special cases, such as for wall coverings in ships, theatres and the like to decrease the inflammability by addition of powdered asbestos, alum and the like, preferably to the fibrous material prior to the addition of the latter to the glue dispersion.

  • the water ratio is higher thanfor the spreadable pap.
  • a satisfactorily sprayable product can be obtained for example by addition of a suitable amount of Water to the spreadable pap or by addition of this extra water during one or more stepsof the preparation of the pap.
  • Another suitable sprayable pap can be obtained according to the following example.
  • Example 1 To parts by weight of a solution of caseinate glue and borax in water in a ratio by weight of 101%:80 a preservator is admixed. Half of this bath is added to 167 parts by weight of cream latex together with vulcanisation dispersion. The remaining half is added to the pap obtained according to Example 1, during the preparation of which 200 parts by weight of chalk in 400 parts of water and 30 parts by weight of water glass in 70 parts of water are added. Thereupon the latex liquid and the pap are mixed under stirring.

  • a flexible product obtained by removing water from a uniform fibrous composition comprising, in intimate admixture, 75-100 parts of a rubber in the form of a latex and an aqueous glue dispersion containing 5-25 parts by weight of glue, and 70-80 parts by weight of loose cellulose fibers suspended therein, said loose cellulose fibers being derived from cellulose flock.
