  • the invention relates to the production of imitation leather, transfer paper and other products from impregnated absorbent paper or fabric.
  • imitation leather is produced having a surface wrinkled or distorted in an irregular pattern similar to that of real leather.
  • the invention also contemplates producing imitation leather which will have the feel of leather to the touch.
  • FIG. 1 illustrates a diagrammatic sectional view of an embodiment of the invention
  • Fig. 2 is a similarview showing the lower portion of the base material stripped ofiyFig. 3 shows the lower stripped portion of the base material with a coating attached to its fuzzy side
  • Fig. 4 is a diagrammatic sectional view of another embodiment of the invention.
  • a of my product an unsized paper of the character known in the trade as waterleaf.
  • a waterleaf sheet which is very-porous and absorbent is preferred Such paper maybe manufactured in any 'regular way' but without simng.
  • the waterleaf sheet may be of any desired or standard weight and thickness but must necessarily be a cellulose material and of a-porous and absorbent nature.
  • a coating b the material of which enters into and anchors itself within the porous absorbent fabric of the waterleaf sheet, the penetration taking the form of microscopic legs extending down into the pores of the water- -leaf. Any standard method of coating may be used.
  • the viscosity of the coating should be such as to permit the coating material to anchor itself thoroughly in the waterleaf in the manner described and not merely to' lie upon the surface of the waterleaf without thorough anchorage in the pores of the paper. In fact there should be preferably only an extremely thin, almost microscopic surface film, so that the coating material is practically all contained, within the body of the "paper with its top surface practicailyhush with theupper fibers of the paper.- When the paper is coated as described, it has a smooth surface and resembles ordinary coated papers in appearance but due to the greater porosity of waterieaf paper, the coating material has penetrated to such an extent not protected by the coating product made as into the o e 0. t e Pa a not (Cl. 8-20) l to have increased materially'the transverse dimensions of the coated product.
  • any available parchmentizing treatment such as is used in the manufacture of vegetable parchment.
  • One method of parchmentizing here referred to for illustrative purposes only, involves passing the sheet through a sulphuric acid bath followed by washing, neutralizing and drying. The eflfect of this treatment is to hydrolize the fibers of the 10 paper, the acid in the state of dilution in which it is' used for the parchmentizing process having no destructive or deteriorating effect upon the coating material. Those cellulose fibers which were material and which received the full "effect of the parchmentizing treatment are chemically changed to -amyleid.
  • a coating material excellently suited for the purposes of this invention is found in the article 40 known as film scrap liquor produced from waste moving picture films and obtainable at low 'cost.
  • This type of material when applied to the waterleaf paper, should be applied without having much excess ,of the liquor lying upon the surface, as such excess may result in the formation of blisters when the fibers of the paper are dis-.
  • coating materials may be employed and for this purpose I may use any substance capable of absorption by the base and not subject to diswill be not a leather substitute but a transfer,
  • This fiber is still partly in its initial felted condition but has innumerable ends which extend outwardly from the underside of the coating material rendering the undersurface c somewhat fuzzy and-therefore susceptible of forming an excellent union with another material with which it may subsequently be adhesively associated.
  • the coated surface when split away from the coated surface also has a fuzzy or fibrous surface 9 on the side which was split away, while the opposite surface it is tough and well parchmentized.
  • the fuzzy part of the sheet 9 may now be coated in the regular way by applying a coating material 7' to the fibrous or fuzzy side 9, as shown in Fig. 3, which side offers an excellent surface for holding coating material to the sheet or for adhesive connecion with similar or other materials.
  • the stripped parchmentized portion) of the sheet a may, of course, also be creped or otherwise treated and be put to a variety of uses.
  • the paper may be'passed from a roll through a conventional lacquer-applying coating machine, be then drawn through a tower within which the lacquer is given an opportunity of setting and drying before the paper is introduced to the chemical or acid bath of the parchmentizlng step or the coated paper may be wound up on rolls and introduced to the acid treatment as desired from time to time and independently of the coating step,
  • coating material is applied to parchmentized paper, it does not adhere sufficiently to result in a practical product nor will the coating in such a case be contorted into a leather-like appearanceo
  • a baseof cellulosic fibrous material sufliciently porous and absorbent to permit the coating material to find a thorough anchorage followed by the application to the coated fabric of a chemical 10 treatment to parchmentize the vegetable fiber.
  • the coating should in each instance be of such a nature as not to be aflected by the chemicals of the parchmentizing step. Any suitable color may be imparted to the coating.
  • ground wood paper unsized or cotton or other vegetable fabric may be used for the base material provided always that the material possesses the requisite porosity and absorbent quality.
  • the paper may be directly formed from the pulp upon a woven or similar fabric.
  • a coarse material such as cheesecloth Ic having open meshes, may have a layer Z of matted paper pulp fibers applied to it in the paper mill, the fibers of the paper in that case anchoring themselves in the meshes of the cloth.
  • the cloth can be covered with the paper pulp on one or both sides, as it is desired.
  • the coating will then be applied to this base material as hereinabove described. And in such case after the coating is applied to the paper surface, the parchmentizing treatment will not only securely anchor the coating in the paper layer but will also anchor the parchmentized paper in the woven material yielding a product of great strength.
  • the process which comprises applying to one surface of a waterleaf sheet a coating composed of material that is not affected by the chemicals used in the parchmentization of fibrous matter and having sufficient fluidity to anchor itself thoroughly in the pores of the waterleaf sheet, and then so rapidly parchmentizing the waterleaf portion of the combined structure as to parchmentize materially more actively the outer, surface of the waterleaf than its inner portion, and finally stripping the parchmentized.
  • a product comprising a layer of vegetable fibers parchmentized throughout its mass, said layer being parchmentized to a greater degree on one side than on the other side, the more parchmentized side of said layer having a tough relatively impermeable surface andsaid other side having a fuzzy surface, and coating material 40 anchored in the fuzzy side of said layer and .tenaciously held thereto in inseparable relation by the fuzzy portions thereof.
  • a product comprising a layer of vegetable fibers parchmentized throughout its mass and a coating carried by said layer, a portion of the material constituting said coating penetrating the surface of said layer and extending into the body of said layer in the form of microscopic legs, said legs beingtenaciously held in the body of said layer, in gripped relation, by the parch- I mentized fibers thereof so that that portion of the coating which covers the surface of said layer is held thereto in inseparable relation.
