  • the polyurethane sheet can be of various thickness as, for example, between about 0.5 mils and about 3 mils.
  • Bladder 12 includes a foot portion 14 having an outer surface 16 and an inner surface 18.
  • Bladder 12 has the unique capability of generally conforming to the contours of the human foot so that it can be comfortably worn inside a boot or shoe.
  • Bonded to the inner surface 18 of the elastomeric bladder is a light-weight covering member such as a fabric inner sock 20 of standard construction which is preferably made from knitted natural or synthetic fibers.
  • the article of the invention shown in Figure 3 also includes an outer sock 22 which is bonded to the outer surface of bladder 14.
  • Outer sock 22 can also be constructed from filament or spun yarns.
  • the sock can also be constructed from natural fibers; such as wool fibers, or from a variety of synthetic fibers such as polyester nylon and combinations thereof.
  • Inner sock 20 and outer sock 22 are preferably bonded to bladder 12 by means of a waterproof, heat activated adhesive.
  • Other adhesives can, of course, also be used, including breathable adhesives. In any event, the adhesive should be selected and applied in a manner that the breathability of the footwear is not destroyed or substantially reduced.
  • the footwear article of the invention can be constructed by bonding to the bladder only a single inner or outer sock. This two, rather than three-ply construction, can be used in a number of applications in which the three or more ply constructions are too bulky or too expensive.
  • the thin pliant, thermoplastic material from which the waterproof, breathable bladder will be made is of a character that will prevent penetration of liquid water while at the same time permitting free passage of moisture vapor such as perspiration.
  • This material can be a polyurethane sometimes described as thermoplastic urethane.
  • a suitable material of this type is sold by Fabrite Laminating Corp. of Woodridge, New Jersey.
  • suitable materials include elastomers made from polyesters, co-polyesters, poly amides, cellulose derivatives, poly aery lie acid and its holologs, natural or synthetic rubber with hydrophilic impurities, copolyozamides, polyureas, polyelectrolytes, polyphosphates, polyvinylamid, polyvinylalcohol, polyether, and copolymers thereof, polythioether, polythioether-polyether, copolyepichlorohydrin-ether, polysulphosphates, copolyester-ether and derivatives or mixtures thereof.
  • the thin, pliant bladder material is first coated with a light coating of the powdered hot melt adhesive, Bostik #5116.
  • the adhesive particles randomly cover the bladder evenly to a density of about 20% coverage of the surface area.
  • This bladder material with adhesive is then heated to a temperature slightly above the softening point of the adhesive, thereby causing the discrete particles of adhesive to fuse to the surface of the bladder material.
  • the softening point is 268 degrees Fahrenheit. This means is also used to coat particles of adhesive on both sides of the bladder material.
  • the next step is the construction of the waterproof, breathable bladder.
  • this is accomplished by overlaying two sheets of the previously described adhesive coated bladder material and to define on the sheets of material a line circumscribing the boundary of the bladder. This done, the sheets of material are heated along the boundary line to a temperature sufficient to sealably bond the sheets together along the boundary line.
  • the heating-fusion step can be accomplished in several ways well known to those skilled in the art, including using a heated wire or die having the shape of the bladder-boundary. Heating can also be accomplished through the use of well-known radio frequency and ultrasonic welding techniques.
  • One technique which has proven to be satisfactory in making the footwear of the invention involves the use of a heated platen press embodying a die having the shape of the outer boundary of the bladders. The die is electrically heated to about 500 degrees Fahrenheit.
  • One of the cooperating platens of the platen press is maintained at room temperature and, is lined with a flexible fabric such as felt.
  • the two sheets of the adhesive-coated bladder material are placed between two sheets of polytetrafluoroethylene coated fiber glass sheets which act as separator material and also allow the heat from the die to penetrate to the film.
  • Appropriate heating of the dies causes the sheets of bladder material to be effectively welded, or sealably joined together along the boundary line to make the sock- shaped bladder.
  • the excess material outside the bladder boundary is manually stripped away and the bladder is removed from the platen press.
  • the proper application of the adhesive to the inner and outer surfaces of the bladder is critical to the success of the manufacturing process, since, when completed, the sock must be breathable, flexible, pliant and waterproof and it must withstand laundering and physical abuse while being worn. It is to be noted that the adhesives can also be applied to the fabric components as an alternative means of construction.
  • the next step in the process of the invention is to place the first covering member, or inner sock 20 over a generally foot-shaped, approximately l/8th inch thick, generally planer mandrel 27.
  • Inner sock 20 which has inner and outer surfaces 20a and 20b is placed over the mandrel so that inner surface 20a thereof is disposed in engagement with the faces 27a of mandrel 27.
  • inner sock 20 can be constructed from a variety of materials. However, a sock which is made by Wigwam
  • An alternate inner sock also made by Wigwam, is intended to impart cold weather comfort to the waterproof footwear article of the present invention depending on the climate encountered.
  • the inner sock can be made utilizing Thermax R made by E. I. duPont de Nemours and Co. of Wilmington, Delaware.
  • the inner sock can be made utilizing Coolmax R made by duPont.
  • the precursor assembly comprising first inner sock 20, the adhesive coated bladder 12 and the outer sock 22 is then heated and compressed in the direction of the arrows 34 in Figure 2 to form the finished article.
  • This step is accomplished by placing the mandrel, upon which the precursor assembly is mounted, between two platens which can be controllably heated and urged together. More particularly, the platens are preferably electrically heated to a temperature of about 280 degrees Fahrenheit and are controllably moved into pressural engagement with the precursor assembly by any type of hydraulically actuated pressure imparting assembly of a character well known to those skilled in the art.
  • a commercially available press suitable for carrying out the method of the invention is sold by PHI of the City of Industry, California.
  • the heat activated adhesive is thereby fused making a permanent, water resistant bond of inner sock 20 to one side of the bladder and the outer sock 22 to the other side of the bladder.
  • the minimum temperature required to activate the Bostik #5116 adhesive is 268 degrees Fahrenheit. Accordingly, a temperature range of between about 270 degrees Fahrenheit and 290 degrees Fahrenheit is preferred.
  • the precursor assembly is then removed from the press and allowed to cool thoroughly prior to doffing the completed waterproof footwear article from the mandrel.
  • the footwear article When removed from the mandrel, the footwear article is generally planar in shape. However, upon inserting the foot into the open cuff of the article, the foot engaging portion of the sock will neatly and smoothly conform to the shape of the wearer's foot.
  • adhesives can also be used in the practice of the method of the invention.
  • these include an adhesive sold by Stahl U.S.A. of Peabody, Massachusetts under the designation UE-4172 and an adhesive sold by Reichhold Chemicals, Inc. under the product code EA 6494.
  • a mixture of the Reichhold EA 6494 and a SOLUCOTE R 1024 adhesive made by Soluol Chemical Co. , Inc. can be used for some end product applications.
  • the adhesive used When the adhesive used is in liquid form it can be sprayed, brushed or otherwise applied to the elastomeric bladder or sock fabric. As previously stated when the adhesive is applied to the bladder it must be applied in the manner, such as a dot matrix coating, which will not degrade the breathability characteristics of the bladder material.
  • An alternate form of the method of the invention will next be considered. This form of the invention is similar in many respects to the method described in the preceding paragraphs. However, in this latest form of the invention a different powdered adhesive is used and, importantly, the bladder and the outer sock are both wetted with water during the assembly step to expedite the assembly of the members and to improve the integrity of the finished product.
  • the thin, pliant bladder material or membrane is first coated with a light coating of a powdered hot melt adhesive sold under the name and style of Bostik #5182.
  • the adhesive is uniformly distributed over the membrane material preferably at the rate of about 16.5 grams per square yard and is thermally fused to the membrane in the manner previously described.
  • the second side of the membrane material is similarly coated and fused with Bostik #5182 at a rate of about 16.5 grams per square yard.
  • the fusing of the adhesive to the membrane must be done with great care to carefully control the radiant heating of the adhesive coated membrane.
  • the next step in this alternate method of the invention is accomplished by cutting the coated membrane into first and second segments and overlying the first and second segments to form a coated assembly.
  • a line is formed on the coated assembly which circumscribes the boundary of the bladder which generally corresponds to the extremity to be covered, in this case the human foot. This done, the sheets of material are heated along the boundary line to a temperature sufficient to sealably bond the sheets together along the boundary line.
  • This heating-fusion step is here accomplished using a heated platen press embodying a die having the shape of the outer boundary of the bladders.
  • the aluminum die is electrically heated to about 530 degrees Fahrenheit.
  • the two sheets of the adhesive coated bladder material are placed between two sheets of polytetrafluoroethylene (said under the mark TEFLON coated fiber glass sheets which act as separator material and also allow the heat from the die to penetrate to the film.
  • Appropriate heating of the dies causes the sheets of bladder material to be effectively welded, or sealably joined together along the boundary line to make the sock-shaped bladder.
  • the assemblage is backed by a 1/2 inch thick sheet of temperature hardboard and a pressure is exerted on the assemblage sufficient to cleanly pinch off the membrane material surrounding the die.
  • the next step in the alternate process of the invention is to place the first covering member, or inner sock 20, over a generally foot-shaped, approximately l/8th inch thick, generally planer mandrel 27.
  • Inner sock 20, which has inner and outer surfaces, is disposed in engagement with the faces 27a of mandrel 27.
  • inner sock 20 can be constructed from a variety of materials.
  • Mandrel 27 can also be constructed of various materials but here is formed a sheet of aluminum having a thickness of about 0.032 inches. The edges of the mandrel are smoothed and rounded and preferably coated with a thin strip of TEFLON which may comprise a 1/2 inch wide strip of pressure sensitive adhesive coated TEFLON tape.
  • inner sock 20 After inner sock 20 has been placed over mandrel 27 and smoothed out so that its inner surface is in close engagement with the faces of the mandrel 27, the bladder 12, which has been adhesive coated with particles of hot melt adhesive inside and outside is immersed in water causing it to expand slightly. The water saturated, expanded bladder is then carefully placed over the assemblage of inner sock 20 and mandrel 27. The bladder is smoothed to be in close engagement with the outer surface of inner sock 20. Outer sock 22 is then also wetted by immersing it in water or otherwise wetting it and is carefully placed over both the inner sock 20 and the adhesive coated bladder assemblage on mandrel 27.
  • the precursor assembly comprising inner sock 20, the adhesive coated bladder 12 and the outer sock 22 is then placed between heated platens and heated to about 275 to 325 degrees F for about three to five minutes.
  • the bottom platen is a rigid sheet of aluminum covered with a 1/4 inch thick sheet of about 50 derometer silicone rubber. The heated assemblage is then compressed by substantial compressive force in the direction of the arrows
  • the compressive forces can be exerted on the heated precursor assembly in various ways such as hydraulically-actuated, pressure-imparting assembly, or press, previously described herein.
  • the compressive forces can be applied by passing the precursor assembly between pressing rollers of a character well known to those skilled in the art.
  • a pressure of at least two pounds per square inch is exerted on the precursor assembly for about four minutes.
  • the precursor assembly is immediately plunged into a bath of cool water for several minutes. This step quenches the adhesive, arresting crystalline growth and thereby providing a more amorphous molecular structure and pliant adhesion.
  • the bladder is softened and expanded by the water for ease of removal from the mandrel. The wet sock assemblage is then removed from the mandrel and allowed to dry.
  • the thin, pliant bladder material or membrane 50 comprises an extruded film made by The Dow Chemical Company and sold under the name and style "PELLETHANE No. 2103-89AE" .
  • the membrane which comprises polytetramethylene glycol ether, is preferably about 0.001 inches thick is first coated with a light coating of a powdered hot melt adhesive sold under the name and style of Bostik HM 5184-AB which is available from Bostik, Inc. of Middleton, Massachusetts.
  • This particular adhesive is a powdered hot melt adhesive with a low activation temperature of about 260 Fahrenheit.
  • the particle size is such as can be sieved through a mesh with approximately 200 micron apertures.
  • the adhesive is uniformly distributed over the membrane material preferably at the rate of about 16.5 grams per square yard and is thermally fused to the membrane by passing a radiant heater over the adhesive-coated membrane.
  • the radiant heater is controllably passed over the adhesive coated membrane in a manner to elevate the temperature of the adhesive above its melting point, thereby fusing the adhesive to the membrane without melting the membrane. More particularly with the temperature of the heater set at about 764 degrees Fahrenheit, the heater is preferably passed over the assemblage at a rate of travel of about 92 inches per minute.
  • the face of the radiant heater is preferably positioned about 2 1/4 inches above the membrane. The membrane with adhesive fused to one side is then turned over with the uncoated side facing up.
  • a coating of the powdered adhesive is distributed on the second side of the membrane and is fused to the membrane in the manner just described, thus providing a membrane with adhesive particles fused uniformly to both sides.
  • the next step in this latest method of the method of the invention is accomplished by means of a thermo plastic welding process which is carried out in a suitable platen press. More particularly, in accomplishing this welding step, the bottom platen of the press is preferably covered with a thin sheet of silicone rubber of about 70 shore hardness. This layer is in turn covered with a sheet of fiberglass material which has been coated with a fluorocarbon polymer. This done, two thicknesses of the adhesive coated membrane are laid together and placed onto the bottom platen of the press.
  • a second sheet of fluorocarbon polymer coated fiberglass material is next placed over the sheet of adhesive coated membrane.
  • the upper platen of the press which is equipped with a die in the desired shape of the sock is then heated and controllably forced against the two thicknesses of adhesive coated membrane which are resting on the lower platen of the press.
  • the lower platen is not heated and remains at room temperature.
  • the welding press is equipped with controls so adjustments may be made to vary temperature, dwell times and the force imposed by the platens one against the other.
  • a movable heat shield Disposed between the upper and lower platens is a movable heat shield which protects the adhesive coated membranes from the heat of the upper platen as it is forced into juxtaposition with the lower platen.
  • the die is strategically designed to have a depth sufficient to accept the heat shield within the sock shape and effectively prevent the two thicknesses of adhesive coated bladder material from welding one to the other.
  • Suitable process parameters for carrying out the membrane welding step are: a) Upper platen temperature 572 to 625 degrees Fahrenheit; b) Dwell time 2.5 to 3.5 seconds; and c) Inter-platen force 2800 to 3200 pounds.
  • the first covering member, or inner sock 52 (Figure 7) is placed over a generally foot-shaped, aluminum mandrel 54 ( Figure 5), which has a thickness of about 1/32 inch.
  • the inner sock is constructed from a fabric comprising a polyester fiber and a texturized nylon fiber.
  • a suitable, commercially available material for constructing the inner sock is one sold by DuPont under the name and style "COOLMAX" .
  • COOLMAX One reason for selecting this particular material is the excellent water- wicking characteristics exhibited by the fibers, the importance of which will presently be described.
  • the precursor assembly comprising inner sock 52, the adhesive coated bladder 50 and the outer sock 56 is then smoothly arranged over the aluminum mandrel with sock 52 against the mandrel, sock 56 on the outside and adhesive coated bladder 50 disposed intermediate the first and second socks.
  • the precursor assembly is next laminated using a commercial platen press of the character having a controllably heatable upper platen.
  • Suitable process parameters for the lamination step are:
  • the laminated precursor assembly is pulled from the mandrel and allowed to cool to room temperature. During cooling, the precursor assembly normally shrinks to a size only minimally smaller than the size of the mandrel.
  • An optional step in this latest method of the invention is to inflate the laminated precursor assembly with several pounds of air pressure and then submerge it in water in order to test it for leaks. Leaks are evidenced if a stream of bubbles emanate anywhere from the sock.
  • the precursor assemblage is leak tested or not, the assemblage is preferably wetted and then dried in a heated tumble dryer of the character used in a home laundry. This causes the nylon sock to shrink markedly and also causes the assemblage to become quite elastic so that it will comfortably fit feet of differing sizes.
  • Still another optional step in the method of the invention is to stitch together the inner and outer socks and the bladder at a location proximate the cuff of the assemblage. This tends to stabilize the assemblage and prevent delamination during extended use.
  • the chosen material for the inner liner 52 namely DuPont's
  • Coolmax polyester fiber is an efficient wicking fiber which rapidly moves water moisture along the fibers. This capillarity action is due in large measure to four longitudinal grooves formed along the length of each fiber. In use it has been observed that the fibers enhance transport of the perspiration over a wide area inside the sock thereby exposing a greater area of the bladder to the moisture source. By thus moving the perspiration along the wicking fibers, the wearer is made much more comfortable than is the case where the inner liner is not constructed from wicking fibers.
  • This article comprises a glove construction including a thin, pliant bladder constructed from any of the waterproof, breathable materials previously identified herein.
  • the bladder can be of various thicknesses ranging from about 0.5 mils to about 3.0 mils.
