Definitions

  • the present invention is directed to insulated breathable fabrics, in particular insulated breathable laminates.
  • Breathable fabrics that allow transfer of water vapor have become important in a wide number of applications. These applications include, for example, use in all- weather clothing, medical garments, and environmental protection suits. Breathable fabrics are particularly useful for garments that will be used in wet environments and for active pursuits where a user will produce significant amounts of perspiration. Under such circumstances a breathable garment with a PTFE membrane can provide an improved level of comfort for the wearer, while preventing excess moisture from penetrating into the interior of the garment.
  • PTFE polytetraflouroethylene
  • the present invention is directed, in part, to a multilayer breathable fabric comprising a bicomponent membrane.
  • the bicomponent membrane includes a porous scaffold material having a void volume of at least 60% and an interconnecting microstructure, plus a resin composition applied to at least one surface of the scaffold material.
  • the resin partially fills the voids sufficient to create adhesion of the resin to the scaffold material, but not such that all voids within the scaffold are filled.
  • An insulating layer is placed in contact with the bicomponent membrane, and is secured to the bicomponent membrane by a discontinuous adhesive layer,
  • the porous scaffold material comprises polytetraflouroethylene (PTFE).
  • PTFE polytetraflouroethylene
  • the porous scaffold material is at least 10 microns thick, while it can be thicker or thinner in some implementations.
  • the invention is also directed to a multi-layer fabric comprising a breathable membrane, the breathable membrane combining an expanded PTFE film partially impregnated with a resin material; and insulating layer in contact with the breathable membrane.
  • Suitable resin materials include polyurethane.

However, in some implementations where water resistance need not be at a maximum, the water column can be significantly less than these numbers. Waterproofness is measured by the ability of the material to hold back a column of water over a defined period of time, typically using the test method of ISO 811.
  • the laminate fabric of the present invention has a high moisture vapor rate, usually in excess of 400 gm/m 2 /24 hours, and preferably greater than 600 gm/m 2 /24 hours, and may be in excess of 800 gm/ m 2 /24 hours.

  • Suitable organic peroxides include dibenzoyl peroxide, bis-2,4-dichlorobenzoyl peroxide, di-t-butyl peroxide, 2,5-dimethyl-2,5-di- (t-butylperoxy) hexane, and dicumyl peroxide.
  • Precious metal containing catalysts can be based on the metals rhodium, ruthenium, palladium, osmium, irridium and platinum. It is particularly preferred that a platinum metal complex be employed as the catalyst, for example, as taught by Ashby in U.S. Pat. Nos.
  • the addition curable silicone composition further includes a reinforcing organopolysiloxane resin of the type disclosed in U.S. Pat. No. 3,284,406 to Nelson or U.S. Pat. No. 3,436,366 to Modic.

  • the use of such reinforcing organopolysiloxane resins is especially desirable when the viscosity of the alkenyl containing polydiorganosiloxane is less than about 5000 centipoise. It is also contemplated that there may be included any conventional extending and/or reinforcing fillers. Fumed silica has been found to be particularly effective as reinforcing filler for the silicone component of the present invention.
  • the addition curable silicone composition also contains a silane or polysiloxane which functions both as an inhibitor and as an adhesion promoter.
  • a silane or polysiloxane which functions both as an inhibitor and as an adhesion promoter.
  • a silane or polysiloxane which functions both as an inhibitor and as an adhesion promoter.

  • a polydiorganosiloxane having terminal hydrolyzable groups e.g., hydroxyl or alkoxyl
  • a catalyst which promotes condensation curing e.g., hydroxyl or alkoxyl
  • the polysiloxane network can be prepared by the hydrolytic polycondensation of silanes having the general formula where each X is independently selected from the group consisting of hydrogen, alkyl radicals, hydroxyalkyl radicals, alkoxyalkyl radicals, and hydroxyalkoxyalkyl radicals, and Y is an alkyl radical, OX, where X is as previously defined, or an amino or substituted amino radical.
  • silanes having hydrolyzable groups to form a polysiloxane network of an interpenetrating polymer network is discussed in greater detail in U.S. Pat. No. 4,250,074 to Foscante et al.
  • the amount of curable silicone composition used in practicing the present invention can range from as little as about 1 part by weight per 100 parts by weight of component (a) to as much as about 150 parts by weight per 100 parts by weight of component (a).
  • a particularly preferred embodiment of the present invention utilizes from 1 to 50 parts by weight silicone per 100 parts by weight of component (a).
  • Optimal results are obtained when from about 5 to about 35 parts by weight of silicone composition are used per 100 parts by weight of polytetrafluoroethylene. It should be noted that the translucency of the final product increases as the ratio of silicone composition to PTFE increases.
  • compositions having interpenetrating matrices in cured form will be described only with respect to polytetrafluoroethylene and addition curable silicone compositions.
  • Those skilled in the art will appreciate that in order to prevent premature curing of the silicone composition the components must not all be combined until the time of use unless a suitable inhibitor is included (or moisture excluded in the case of condensation curable silicone compositions).
  • a one component, addition curable silicone composition containing an amount of inhibitor effective to prevent curing below about 100 0 C is dissolved in a suitable solvent, for example, kerosene or mineral spirits.
  • a suitable solvent for example, kerosene or mineral spirits.
  • the resulting solution is thereafter mixed with the polytetrafluoroethylene powder in a tumbler-type mixer suitable for mixing liquids with solids in order to incorporate the desired level of silicone into the PTFE.
  • the semi-dry powder obtained is a mixture of PTFE, silicone composition and solvent which can be pressed into a cylindrical bar or other suitable shape.
  • the cylindrical bar is then extruded and calendered to provide a film of desired thickness.
  • the film can be stretched to provide a film having a porous microstructure consisting of nodes and fibrils.
  • expansion of the film can be carried out at temperatures ranging from room temperature to about 325 0 C, it is preferable that the temperature range from about 250 0 C to about 300 0 C so that the silicone composition cures during the stretching process.
  • an inhibitor is not present to prevent premature curing of the silicone composition, it is desirable to prepare a mixture of PTFE and vinyl containing polydiorganosiloxane and a mixture of PTFE and organohydrogenpolysiloxane, either or both mixtures also containing a curing catalyst. At the time of use the powders are combined and the final product prepared as if an inhibitor were present.
  • Stretched films prepared in accordance with the present invention generally have thicknesses ranging from about 0.5 mils to about 10 mils. Quite surprisingly, however, the resultant materials had larger pore sizes than similar materials prepared solely from PTFE, yet they exhibit improved air permeability and improved resistance to liquid water permeability.
  • the expanded products be heated to above the lowest crystalline melting point of the PTFE so as to increase the amorphous content of the polymer, typically to 10% or more.
  • Such amorphous regions within the crystalline structure appear to greatly inhibit slippage along the crystalline axis and thereby lock fibrils and nodes so that they resist slippage under stress. As a result, a surprising increase in strength is obtained.
  • Compositions prepared in accordance with the present invention find particular utility as filters, pump packing, insulation for electrical cables, and as laminates useful in the manufacture of breathable wearing apparel.
  • the insulating layer provides insulating, anti-static and other therapeutic attributes.
  • the present invention provides an advantage by producing a waterproof or water-resistant fabric that also shows effective insulating properties.
  • Suitable insulating layers include synthetics like Lite-Loft, Primaloft, Polarguard, Hollofil, Microloft, etc., all of which have good performance in wet conditions. They are also relatively easy to clean, resistant to mildew and rot, and quick drying.
  • the insulating material can include, for example, material disclosed in U.S. Patent No. 4,992,327, incorporated herein by reference.
  • Such insulating layers can include synthetic fiber thermal insulator material in the form of a cohesive fiber structure, which structure comprises an assemblage of: (a) from 70 to 95 weight percent of synthetic polymeric microfibers having a diameter of from 3 to 12 microns; and (b) from 5 to 30 weight percent of synthetic polymeric macro fibers having a diameter of 12 to 50 microns, characterized in that at least some of the fibers are bonded at their contact points, the bonding being such that the density of the resultant structure is within the range 3 to 16 kg/m , the thermal insulating properties of the bonded assemblage being equal to or not substantially less than the thermal insulating properties of a comparable unbonded assemblage.
  • Microfibers and macrof ⁇ bers for use in inslulating layer of the present invention may be manufactured from polyester, nylon, rayon, acetate, acrylic, modacrylic, polyolefins, spandex, polyaramids, polyimides, fluorocarbons, polybenzimidazols, polyvinylalcohols, polydiacetylenes, polyetherketones, polyimidazols, and phenylene sulphide polymers such as those commercially available under the trade name RYTON.
