  • the thermal control nonwoven material has a polymeric binder dispersed throughout its interior, and thermal control material dispersed throughout the interior of the binder.
  • the binder in the nonwoven may be a continuous filling or it may be discontinuous, as will be explained.
  • the thermal control nonwoven material according to this invention has the ability to protect against hot or cold environments, by virtue of the absorption and/or release of heat from the thermal control material.
  • the nonwoven textiles can be made up of a wide variety of substances.
  • the nonwoven can be formed from cellulosic, polyolefm (for example, polyethylene, polypropylene and the like), polyesters, polyamides (for example, nylon), bi-component materials or mixtures of the above, and even inorganic fibers.
  • These fibers can be of lengths between about 0.3 and about 7 cm, depending on the method of web formation and bonding desired, alternatively, the fibers can be longer, including a fiber or fibers prepared by continuous extrusion of a melted polymer via spunbond/meltblown technology. Fibers can range from about 0.5 to about 30 denier.
  • Nonwoven textiles are prepared in two distinct steps: the first step is formation of a loose bat or web, and the second is bonding of the bat or web, for example by binder, or physical fusion of the bat or web at its junctions, or entanglement of the bat or web to create a nonwoven.
  • Web formation can be carried out according to any of the methods known in the art.
  • the web can be made by a dry-laid process, in which rotating rollers having fine teeth along their circumferences are used to card individual fibers into a substantially parallel-laid, or unidirectional, web.
  • Such unidirectional webs can be combined by crosslapping, in which individual unidirectional webs are built up at an angle to each other.
  • the web can be made by a wet-laid process, in which fibers are dispersed in water and passed over a belt screen. The water is extracted through the screen, and the resulting web is formed on the belt. This method produces a dense, uniform and strong web.
  • Random-laid (isotropic) webs can be created by air deposition, which involves blowing fibers randomly onto a screen.
  • fibers can be laid randomly onto a preformed nonwoven scrim, which takes the place of a screen.
  • fibers could be blown onto a preformed web having binder with thermal control material dispersed within the binder, to form a bi-layered product with one layer having thermal control properties, and another layer without such properties.
  • such a product could be made with one layer of approximately 200 g/m2 of nonwoven including thermal control material, and another layer of approximately 200-800 g/m2 of nonwoven having been blown onto the thermal control nonwoven.
  • Random-laid webs can be created also by melt-blowing processes, where fibers are directly spun from a polymer, drawn and torn to varying lengths by the air stream, and deposited to form a substrate.
  • spunbonding can be used to create virtually endless fibers from granules of raw material. The fibers are stretched by (heated air) and laid into a web. These processes produce nonwoven fabrics in a single, continuous process. For insole constructions, the nonwoven can take a number of forms. The type of material used depends on the required end use of the material.
  • the non-woven fabric preferably comprises a stiff, rigid board, formed, for example, from a blend of polyester fibers with a range of decitex values with a stiff polymer binder.
  • the nonwoven fabric preferably comprises, for example, a blend of coarse polyester fibers having a decitex value of about 6, with a soft, resilient polymer binder to give a material having a resilient and open structure.
  • the web After formation of the web, and in some embodiments, after any eventual slight prebonding of the web (to be described below), the web is submerged in a bath containing a suspension or dispersion of polymeric binder and thermal control material.
  • a nonwoven is created in which the web is bonded to itself by binder, at least at points of intersection.
  • the web is substantially continuously filled with polymeric binder, while in other embodiments, the polymeric binder is present substantially at the web junctions, and the interstices are substantially filled with a gas, such as air.
  • Binders useful in fabrics of this invention are solids at temperatures of fabric use, preferably resulting in nonwoven which are washable and dry cleanable.
  • the binder can have a high melting point. If not dissolved, however, suitable binders generally flow below the softening point of the base material of the web. Some suitable binders are polymeric materials. Particularly useful are polymer dispersions or emulsions which are able to form adhesive and/or cohesive bonds within the web, for example by crosslinking to itself, or by crosslinking to the web itself.
  • polymeric binders examples include acrylics and polyacrylics, methacrylics and polymethacrylics, polyurethanes, nitrile rubbers, styrene/butadiene copolymers, chloroprene rubbers, polyvinyl alcohols, or ethylene/vinyl acetate copolymers, and mixtures thereof.
  • Latex binders can also be used, including water-based latex blends.
  • the latex binder comprises a stiff styrene/butadiene rubber latex.
  • the binder includes a thickener, for example ammonia and an acrylic latex that reacts with the thickener (for example, ammonia) to thicken the mixture.
  • a suitable latex binder comprises a blend of 75% by weight of Applied Polymers S30R and 25% by weight of SynthomerTM 7050. This blend can be thickened with ammonia and an acrylic latex such as, for example, NiscalexTM HN30, manufactured by Allied Colloids.
  • thermal control materials include phase-change materials, such as those discussed below.
  • This submersion step is carried out to the extent necessary to allow substantially complete penetration of the suspension or dispersion into the web.
  • the bath can be heated, in order to effect fusion of the fibers at points of intersection.
  • the web is then dried to remove any solvent (i.e. water), resulting in a nonwoven textile having binder and thermal control material in the interstices of the web material.
  • the web can be passed through rollers, which can be heated or not heated. Warmed or hot air can also be used to dry the web.
  • the interstices of the resulting web are substantially filled with binder and thermal control material.
  • a preferred embodiment of the invention has the binder located almost entirely at points where the web intersects itself, leaving the remainder of the interstices filled with gas, typically air, which imparts thermal insulative properties to the material.
  • gas typically air
  • the binder acts as the bonding agent of the web to itself as well as the bonding agent of the thermal control material to each other and to the web, thus forming a bonded nonwoven with thermal control material dispersed therein.
  • Nonwoven textiles according to such embodiments can be prepared by utilizing the surface tension of the binder, and the relative affinities of the binder for the web and for itself. A binder which shows excessive self-affinity will not be prone to bind to the web at all, while a binder which shows excessive affinity for the web will not form islands or globules at the web's intersection points. The rate at which any solvent is removed from a binder can also affect the extent to which binder forms islands or globules at the web intersections.
  • the web is substantially entirely filled with binder, the binder having thermal control material dispersed throughout it.
  • Embodiments in which the web is filled can also call for relatively flexible binder material, or can call for relatively rigid binder material, depending on the application.
  • the viscosity of the binder can be modulated to produce nonwoven fabric having binder coagulated at the interstices of the web.
  • the binder coagulates at the interstices of the web, as shown in Fig. 1 and Fig. 2.
  • the bonding of the web is carried out preferably immediately after web ' formation, by submersion of the web into binder bath containing the thermal control material.
  • slight prebonding processes including binder spray-bonding, thermal bonding processes, needling processes and water-jet bonding processes may be carried out prior to the submersion of the web into the binder bath and final bonding of the nonwoven.
  • These processes can impart various qualities to the finished product, as recognized by those of skill in the art.
  • needling or water-jet bonding can be used to produce relatively dense and stiff nonwovens, as well as relatively light and voluminous nonwovens, depending on the needling or water-jet density and pressure.
  • a preferred web can be a non- woven needle felt.
  • spunbonded webs can be submerged in the above-described chemical bath subsequent to their bonding.
  • the thermal control materials that can be included in the textiles are those suitable for protection against cold and/or heat. Particularly useful thermal control materials include phase change materials. Phase change materials that are encapsulated, particularly micro encapsulated, are useful in the invention.
  • Microcapsules suitable for the present invention may contain a wide variety of materials. The choice of materials is limited only by the conditions for processing of the textiles disclosed herein. Microcapsules suitable for the present invention have diameters ranging from 15.0 to 2,000 microns. Preferably, the microcapsules have diameters of from 15 to 500 microns. Most preferably, the microcapsules have diameters of from 15 to 200 microns.
  • Phase change materials are well suited for inclusion in microcapsules, wherein the microcapsules have a diameter of the same order as, or greater than, the diameter of the material making up the nonwoven.
  • Phase change materials are designed to utilize latent heat absorption associated with a reversible phase change transition, such as a solid-liquid transition. Certain phase change materials also absorb or emit heat upon solid-solid phase transitions.
  • the material can be used as an absorber of heat to protect an object from additional heat, because a quantity of thermal energy will be absorbed by the phase change material before its temperature can rise.
  • the phase change material can also be preheated and used as a barrier to cold, as a larger quantity of heat must be removed from the phase change material before its temperature can begin to drop.
  • phase change materials which are preferred for the present invention utilize a reversible solid-liquid transition.
  • Phase change materials store thermal energy in the form of a physical change of state as the core material within the microcapsules melts or freezes or undergoes a solid-solid transition. These materials will absorb or emit heat at a constant temperature (their phase change temperature) before changing phase.
  • the material can be used as an absorber of heat to protect an object from additional heat as a quantity of thermal energy will be absorbed by the phase change material before its temperature can rise.
  • the phase change material can also be preheated and used as a barrier to cold, as a larger quantity of heat must be removed from the phase change material before its temperature can begin to drop.
  • phase change materials In order to maintain the ability of the phase change materials to recycle between solid and liquid phases, it is important to prevent dispersal of the phase change materials throughout the solvent (or carrier fluid) when they are in the liquid form.
  • An approach which has found success is encapsulation of the phase change materials within a thin membrane or shell. Such thin membranes or shells should desirably not significantly impede heat transfer into or out of the capsules.
  • the capsules can desirably also be small enough to present a relatively high surface area. This makes rapid heat transfer to and from the carrier fluid possible.
  • Such capsules are known as microcapsule. Microcapsule range in size from about 10 to about 50 microns and are formed according to conventional methods well known to those with skill in the art.
  • Heat transfer across the microcapsule material into its interior should be efficient for maximum utility in the present • invention.
