Definitions

  • FIG. 5 is a diagrammatic representation of FIG. 5.
  • This invention relates to the production of foamed articles. It more particularly refers to the production of reinforced foam articles.
  • the outer sole material is especially chosen for its wear characteristics as well as for its customer appeal in the esthetic sense.
  • the inner sole is also required to be esthetically pleasing to the customer.
  • the inner sole also serves a utilitarian purpose in that it provides support and cushioning whereby the comfort of the shoe wearer is increased.
  • inner soles are made of cork, plastic foam or other resilient material in which case it has been found desirable to coat that surface of the inner sole adjacent the wearers foot with a flexible, relatively impervious material.
  • the inner sole is usually produced by pasting or gluing the resilient layer to the impervious coating therefor.
  • the foamable paste is allowed to foam whereby pressure is exerted upon the resilient films causing them to assume the shape of the mold cavity.
  • the foaming process inherently causes the resilient films and the contained foam to adhere to each other by means of the heat of foaming as well as the tacky nature of the foam during its creating.
  • the film and the foam actually partially merge together partially dissolving each other or fusing together and thus belcoming intermingled whereby excellent adhesion resu ts.
  • this invention resides, in one of its aspects, in a process for the production of film-foam articles having only a single film layer coating the foam member thereof.
  • a bipartite mold is used as in the prior art. This mold has a cavity containing longitudinal shoulders therein upon which is placed the film coating member such that this film drapes between the shoulders and rests upon the bottom of the mold cavity.
  • a batt of non-woven fabric is placed up on the draped film member.
  • This batt may be constructed of substantially any fiber desired such as nylons, polyesters, polyacrylics, modacrylics, cellulosics, wools, etc. It is preferred to utilize relatively long fibers in producing the batt such as for example about 3 to 6 cm. long, preferably about 4 cm. It is also preferred to use fairly rough staple fibers such as for example about 15 to 30 denier, preferably about 20 denier. It is essential to the practice of this invention that the batting used be needled. Needling imparts strength to the batt and makes such resistant to delamination.
  • a foam-forming composition is placed on the nonwoven batt and the mold halves closed taking care to insure that neither the film nor the batting edges are disposed between the meeting surfaces of the mold halves.
  • the foam forming material is then permitted to foam whereby it impregnates the non-woven fabric by reason of the pressure exerted by the foam filling the mold cavity.
  • the expanding foam forces the film coating member to fill out the mold cavity by slipping off the aforementioned shoulders and being pressed into the cavity recesses.
  • vacuum may be applied to the recesses of the mold cavity in order to aid in filling out the cavity by the foam and insuring that the film coating member conforms to all shapes of the mold cavity.
  • This vacuum may be drawn through appropriately positioned and sized channels through the mold body as is known in the vacuum forming art. It is preferred to position at least some of the vacuum channels in the deepest and most remote recesses of the mold in order to insure filling of the most inaccessible areas.
  • the expanding foam is self-adherent both to the non-woven fibrous batt and to the film coating member under the conditions of foaming.
  • a flexible article having excellent dimensional stability, strength and good continued integrity.
  • the coating film used in this invention may be of any of the known film forming resilient materials such as for example polyvinyl chloride, polyvinylidene chloride, polyethylene, expanded polystyrene, ethylenevinylacetate copolymer, polypropylene, acrylate homo and copolymers etc. It is preferred to use polyvinylchloride or expanded polyvinylchloride film in this use.
  • the foam material used in this invention may be any of those known in the art such as polyurethane, flexible polyvinylchloride, flexible styrene-acrylo-nitrile-butadiene, polyisoprene, polychloroprene, etc. which can be manufactured by known processes using internally produced blowing agents or externally added artificial blowing agents.
  • the nature of the foam is to a great extent determined by the particular end use to which the composite product will be put. It is preferred for most general applications to use an arylene di-isocyanate-polyester derived polyurethane flexible foam.
  • FIGS. 1 through are all front elevations in section of the process of this invention showing the sequential process steps.
  • FIG. 1 shows the lower half 1 of a bipartite mold having a cavity 2 and meeting faces 3 and 3.
  • This mold is so constructed that shoulders 4 and 4 are provided about the periphery of the cavity 2 thereof. These shoulders preferably have sloping upper faces 5 and 5'.
  • An appropriately shaped film 6 is draped between the shoulders 4 and 4 and the bottom 7 of the mold.
  • FIG. 2 shows the second step in the process wherein a non-woven textile fabric 8, of the type described above, is disposed upon the film.
  • FIG. 3 shows the third step in the process wherein a foam-forming material is disposed upon the non-woven textile fabric 8. and the top half 10 of the bipartite mold is closed so that its meeting faces 11 and 11 close upon the meeting faces 3 and 3 of the bottom half 1 of the bipartite mold. Car must be taken to insure that neither the film 6 nor the non-woven fabric 8 are trapped between the meeting faces 3, 3', 11 and 11' of the mold halves 1 and 10.
  • FIG. 4 there is indicated that the foam-forming material is starting to expand into a foam 12 forcing expansion of the coating film 6 to fill the mold cavity 2. Filling of the mold cavity by the foam fabric-film composite is aided by the presence of channels 13 through which a vacuum is drawn whereby insuring that the film and its associated components reach all areas of the mold.
  • FIG. 5 there is shown a completed composite article 14 in accord with this invention having a coating film 6,. non-woven textile fabric 8, impregnated and coated with foam 12 which composite completely fills the mold cavity as set forth above.
  • An alternate processing technique envisions applying vacuum through the above referred to channels prior to closing of the mold halves whereby the coating film, and if desired the deposited non-woven textile fabric, whereby the film conforms to the contours of the bottom mold prior to foaming of the foam-forming material. Either alternative has been found to be satisfactory.
  • the coating film conforms to the contours of the mold by a cold drawing process since it hasbeen found that where this film is heated to too high a degree and then suitably formed, it looses its elasticity in addition to becoming weakened due to stretching and the thinning that accompanies such stretching.
  • the bottom half of a mold has a cavity which corresponds to the contour of a sole.
  • the length of the cavity amounts to 23.5 cm., the depth up to 2 cm.
  • a slanted shoulder, measuring 1 cm., runs along the side wall of the cavity.
  • a polyvinylchloride film which is commercially available under the name Hella, is placed into this hollow mold.
  • the contours of this film correspond approximately to the side walls of the cavity in the bottom half-mold. However, the film is cut in such a way that it protrudes approximately 1 cm. beyond the outside of the cavity. It thus covers the shoulders entirely.
  • a needled non-woven fabric made of nylon fibers is placed upon this film. After needling, the weight of the fabric material is, for instance, 100 g./m. The individual fiber length exceeds 4 cm., and the fiber is 20 den.
  • a piece, whose contours correspond exactly the measurements of the indentations in the bottom mold-half is cut out of the needled non-woven fabric material and is inserted.
  • the shoulder is not covered by the fabric only covering film lies there.
  • 50 g. of a paste is poured on it.
  • the paste is prepared by mixing together 60 parts of a polyester prepolymer produced by the reaction of adipic acid and 1,6 hexanediol, and 40 parts of tolylenediisocyanate.
  • the upper mold-half is closed taking care not to jam in the film between the upper and lower mold-halves along the contact points.
  • the mold is closed so tightly that it may resist a pressure of approximately 5 atm.
  • the paste now starts to foam in the mold, and the foam is evenly distributed within the needled fabric.
  • the foam also adheres to the fiber structure of the needled fabric.
  • the customary fervent adhesion between the foam and the covering film takes place.
  • the mold can be opened.
  • the finished, fiber-reinforced insole which is partially covered with a protective foil, is still warm to the touch, after removal from the mold. After a cooling off period, the same can be rolled or exposed to other heavy duties (stresses), without the danger of breaking which has persisted up to now. At the same time, the edges of the sole are exact and distinct.
  • a method of forming a composite foam containing article which comprises providing a mold having a cavity in the shape of the desired article, which cavity has freely accessible shoulders protruding from the side wall thereof; positioning a film in said cavity with the ends thereof resting on said shoulders said film is at least one member selected from the group consisting of polyvinyl chloride, polyvinylidene chloride, polyethylene, expanded polystyrene, ethylenevinylacetate copolymer, polypropylene and acrylate homoand copolymers and the remainder draped between said shoulders; providing a needled, non-woven textile fabric on said draped film; providing a foamable polyurethane composition on said fabric and said cavity; closing said mold such that said film ends are free of said closure; and causing said polyurethane to foam whereby said foam impregnates said fabric, adheres to the fibers of said fabric and adheres to said film, and whereby said foam fills out said cavity and forces said film into the peripheral shape of said cavity.
