Abstract
A fabric for garments to be used in cold temperatures or at high altitudes includes an inner layer comprising a thin, comfortable fabric having relatively poor moisture absorption, such as silk, nylon tricot, or polyester tricot, is laminated to a barrier layer comprising a hydrophobic, moisture and air impervious film such as polyethylene, which in turn is laminated to an insulating layer such as fleece or polyurethane fiberfill. The fabric is laminated using an adhesive comprising a mixture of acrylic and polyurethane with a cross linkage catalyst which reacts with active hydrogen groups in polyurethane, heated for about one minute between 180° F. and 220° F. to dry and cure the lamination.
Claims11
A fabric for use in garments designed for cold temperatures and high altitudes, comprising:
- an insulation layer;
- a thin, moisture and air impervious, hydrophobic, stretchable barrier layer, a first surface of which is laminated to said insulation layer;
- and
- an inner layer comprising a thin, comfortable fabric having relatively poor moisture absorption laminated to a second surface of said barrier layer.
A fabric for use in garments designed for cold temperatures and high altitudes made by the process comprising:
- (a) preparing an adhesive comprising a mixture of acrylic and polyurethane with a cross linkage catalyst which reacts with active hydrogen groups in polyurethane;
- (b) coating a first side of a thin, moisture and air impervious, hydrophobic, stretchable barrier layer with said adhesive and applying an insulation layer thereto;
- (c) forcing said barrier and insulating layers together through a roller, and heating said resulting lamination to a temperature of between 180° F. and 220° F. for about one minute, to dry and cure the lamination;
- (d) coating the unlaminated side of said barrier layer with said adhesive and applying an inner layer thereto, said inner layer comprising a thin, comfortable fabric having relatively poor moisture absorption;
- and
- (e) forcing the layers of the resulting three ply lamination together through a roller and heating the three ply lamination to a temperature of between 180° F. and 220° F. for about one minute, to dry and cure the three ply lamination.
