  • FIG. 2 ETAL METHOD OF MANUFACTURING FABRICS HAVING A SUPPORT BACKINGAND UPSTANDING FILE Filed Dec. 29, 1947 FIG. I FIG. 2
  • a corded material (carpet, velvet, etc.,) is comprised essentially by a support or backing of woven textile fibers and by U-shaped cords knotted orattached to the backing by textile threads.
  • a very commonmethod consists in previously manufacturing chenilles which are. made up of U-shaped cords-tied togetherin a straight line by several textile fibers. The chenilles are then fixed on the backing by a system oftextile knots.
  • Figure 1 shows a chenille constituted by. U-shaped cords I tied together by textile threads 2 and 3.
  • the object of the present invention is to.obvi-..
  • the chenilles are attached by. glu-v ing to a support or backing.
  • the chenilles are. themselves. manufactured by gluing, before being attached. by.- gluing tothe. support or backing.
  • the invention extends methods, but also, by way of new industrial prode nets, to textileproducts similar. to those obtained by previous. methods, such as :chenilles, materials;
  • the invention also extends to other charace teristicsdescribed hereinafter and tov their variouspossible combinations.
  • Fig. 2 shows a warp and a woof used for the manufacture of a chenille in accordancewith the invention.
  • Fig. 3. is' a view, in perspective; of a chenille mountedon; a thread;
  • Fig. 4 is a view in perspective ofa chenille mounted on two threads@ r V
  • Fig. 5 is a view inelevation of an apparatus for'the fixation or the chenilles on their supports.
  • a method in accordance with the invention isnot only to the above.
  • This coating may also.be.-made with emulsions: of polyvinylechlor-ide or. its. copolymers, super: polyamides, etc., solutions may.-a1'so:be,use.d1:of;; synthetic. resins. of. :various vkind s,...or: other a adv.. hesives, orv these adhesives ..or: melted resins .softe; ened or plasticized,etc.,may beused.
  • A. grid. or quadrille; is ....fcrmed;.by;'the superposition: of a sheet-.of textilethreads, coated with; rubber.- base glues; synthetic. resins, .etc.,.
  • the chenille obtained is schematizedpn Elevure 3; Thethread' (or threads); which are coated,
  • chenilles-.thhsused may bemanufactured: as indicated above. They may-alsobemanuface. tured, without .5 any; gluingw by. the; conventional methods. on the; textile industry; or, any; other:
  • a rubber band vulcanized or not, loaded or not with various textile or non-textile loads or both. It is also possible to choose rubber, vulcanized or not, reinforced by isolated textile fibers, or arranged in parallel sheets, of canvas or material, etc. The same combination may be made with any kindsof synthetic resins, polyvinyl chloride and their co-polymers, superpolyamides, etc.
  • a very important modification consists in using as a backing a band of non-vulcanized rubber, the composition of which includes a suitable proportion (1 to 5% or more) of a substance such as diazoaminobenzene which is decomposed during the final vulcanization of the finished material, givin a spongy, flexible and low density structure.
  • a backing can be obtainedin large thicknesses and its compressibllity is a very interesting property for a corded material, particularly for carpets. With an equal thickness, products are thus obtained of an unusual lightness and flexibility and of a very low manufacturing. cost.
  • the backing can also consist of spongy rubber, so-called sponge rubber, pre-vulcanized.
  • any other suitable materials offering the necessary'mechanical qualities and capable of bein glued to the chenilles such as, for instance, agglomerates of silicates or coaltar, of petroleum, etc. made of wood meal, wool, cotton. glass fibers, cork, etc.
  • the chenilles, arranged parallel and as close as desired are glued onto the backing by a slight pressure.
  • the glue which is most appropriate for the coating of the chenilles and for the corresponding backing is used.
  • lit-" is preferable, for gluing the chenilles coated with rubber, or with synthetic resins on the backing of a similar nature. to select a glue of the same kind.
  • the bases of the chenilles arranged in sheets were coated with rubber latex containing the ingredients for vulcanization.
  • the backing was also coated on one face with the same vulcanizable latex. Before or after drying, the chenilles are pressed against the backing to cause the gluing. vulcanization is then effected. Wool, for instance, stands very well the thermal vulcanization treatment for the rubber.
  • corded materials with designs can be obtained.
  • the chenilles thus attached to the backing are attached more strongly than by the conventional method, and the materials manufactured in accordance with the invention can be out along any direction, which is not the case for the conventional chenille materials.
  • the chenilles according to the method of the invention were coated, at their bases, with a rubber latex of the same kind, natural or artificial, as that constituting the backing.
  • the latex must contain the same accelerator as the backing, for its vulcanization.
  • the chenilles After drying of the latex, the chenilles, arranged parallel in sheets, and as close as necessary, were pressed with a slight pressure against the backing, which ensured the gluing. Vulcanization was then eflected.
  • One modification consists in coating, on one face, the rubber backing with benzol or naphtha solvent, which improves its gluing power.
  • the chenilles coated with latex and dried, or even uncoated are strongly glued by simple pressure on the backing thus coated.
  • a substance which is decomposed during the vulcanization, releasing gases, which produces a rubber having a cellular or spongy structure may be added to the rubber mixture of the backing.
  • the chenilles were prepared as in the above type of embodiment, by impregnation of their bases with a vulcanizable latex.
  • the backing was made rough, on one face, by mechanical abrasion, then coated with a vulcanizable rubber cement containing a rubber of the same kind, and the same vulcanization accelerator as the latex of the chenilles. rinated rubber may also be incorporated in this cement.
  • the apparatus comprises:
  • Chlo- Cylinders 5 and 6 for driving and stretching the backing.
  • a free toothed cylinder ID for guiding the material.
  • a driving cylinder H A driving cylinder H.
  • a tunnel oven l2 for vulcanization A tunnel oven l2 for vulcanization.
  • the apparatus operates as follows:
  • the sheet of chenilles l3 comes from the manufacture, the threads being coated with latex as indicated in Figure 4.
  • the sheet is driven by cylinder 4which, at the same time, regulates the spacing of the chenilles.
  • the non-vulcanized rubber web forming the backing unrolls at IE, it is driven and stretched by cylinders 5 and 6.
  • the sheet I3 and the backing l5 are applied and glued one over the other by means of the pressure exerted on cylinder 1 by the toothed cylinders 8 and 9.
  • the material I6 is guided and driven by the cylinders l0 and H inside the tunnel oven l2 where the vulcanization of the latex is effected.
  • the finished material I! goes out at the end of the oven.
  • the tunnel oven 12 may be replaced by a stove wherein the material is suspended from horizontal bars.
  • the invention extends not only to the above methods but also by Way of new industrial products, to textile products similar to those obtained by the above methods such as chenilles, materials, carpets and the like.
  • a process of manufacturing fabric having a support backing and upstanding pile comprising forming a first sheet of adhesive coated parallel warp threads, placing on the first sheet a second sheet of uncoated pile threads parallel to each other and transverse to the warp threads, pressing the threads of the second sheet against the threads of the first sheet to bond them together, cutting the threads of the second sheet between adjacent threads of the first sheet, bending the cut pile thread into U-shape about the warp threads to form a sheet of parallel chenilles in which the free ends of all of the pile threads extend from the same side of the sheet of chenilles and in which the warp threads constitute the opposite side and base of the chenilles, coating the base of the chenilles with an adhesive and contacting the coated base with a support backing to bond the chenilles to the backing.
  • a process of manufacturing fabrics having a support backim; and upstanding pile comprising forming a first" sheet of adhesive coated parallel warp threads, placing on the first sheet a second sheet of uncoated pile threads parallel to each other and transverse to the warp threads, pressing the threads of the second sheet against the threads of the first sheet to bond them together, cutting the threads of the second sheet between adjacent threads of the first sheet, passing the sheet of warp threads carrying the cut pile threads through grooves in a heated cylinder thereby bending the cut pile threads into U-shape about the warp threads to form a sheet of parallel chenilles in which the free ends of all of the pile threads extend from the same side of the sheet of chenilles and in which the warp threads constitute the opposite sides and base of the chenilles, coating the base of the chenilles with an adhesive and contacting the coated base with a support backing to bond the chenilles to the backing.
