The present invention provides a process for modifying the surface of a polyvinyl alcohol film or fabric by applying heat and pressure to the film or fabric to increase the moisture on the surface which is held by the fabric and to coalesce the surface fibers and reduce the porosity of the surface.

A coated barrier fabric for use in a reusable medical product (e.g., surgical gown, surgical drape, etc.) is provided and has two woven or knitted plies. Each of the two plies are coated on one side with a non-fluorine containing polymer and retain similar comfort and feel of uncoated woven or knitted fabrics. The coated sides of the plies face each other (i.e., inwardly) in the interior of the barrier fabric. Because of the orientation of the plies, the coated sides of the plies can come into direct contact with and move freely against each other within the interior of the barrier fabric. The coating on each of the plies is protected from exterior and environmental factors, including repeated institutional laundering/autoclave cycles, that could abrade and degrade the coating. Thus, the useful life of the reusable medical product including the barrier fabric is extended.

The present invention provides a process for modifying the surface of a polyvinyl alcohol film or fabric by applying heat and pressure to the film or fabric to increase the moisture on the surface which is held by the fabric and to coalesce the surface fibers and reduce the porosity of the surface.

An aspect of the invention provides a protective garment comprising a pair of arms and a body portion having a vertical split along its length, the body portion further comprising an opening for receiving a user's head therethrough, wherein at least a part of the protective garment is manufactured from a water repellent material comprising a polyester base and polyurethane coating having a combined weight of 70 to 100 grams per square meter. Another aspect of the invention provides a protective garment comprising a water repellent material comprising a polyester base and polyurethane coating having a combined weight of 70 to 100 grams per square meter. Such a protective garment could include a gown, drape, or bib, for example.

The present invention relates generally to a multifunctional textile produced by a special processing method and the manufacturing method and use thereof. The water repellent agent and flame retardant incompatible with each other are laminated by using special materials and a specific processing method to form a multifunctional textile with special water repellency, soil repellency, oil repellency, mildew resistance and flame retardancy, which comprises a base cloth layer, two composite layers and a flame retardant layer. The base cloth layer has a first surface and a second surface opposite to the first surface, the two composite layers are disposed on the first surface and the second surface respectively, and then the flame retardant layer is disposed on the composite layer of the first surface of the base cloth layer.

A composite material for garments, such as shapewear and sportswear garments, is formed of an outer layer that is highly elastic with high compression and an inner layer provided on the outer layer and made of a material that is elastic, waterproof and oil proof. The outer layer is a fabric base fabricated from a blend of polyester and spandex. The inner layer comprises a coating of polyurethane (PU) containing nano-titanium dioxide (nano-TiO.sub.2). When used to fabricate a garment, the inner layer of the composite material is adjacent to the body of the wearer when the garment is worn such that perspiration from the wearer's skin and/or skin contact products, such as oil/water based body creams and gels, applied to the wearer's skin are not absorbed by the inner layer and are thereby prevented by the inner layer from being transmitted to the fabric base.

The present invention relates to a hydrophobic additive for use with fabric, fiber, and film. One aspect of the present invention comprises a master batch composition for use in preparing a non-woven fabric in order to increase the hydrophobicity of the non-woven fabric. In one embodiment, the master batch composition includes a polymer and a lipid ester. The lipid ester comprises 10 wt. % to 40 wt. % of the master batch. The fabric, when including the master batch composition, has a contact angle ranging from 100 to 125 when measured according to test method ASTM D2578.

The present invention provides a process for modifying the surface of a polyvinyl alcohol film or fabric by applying heat and pressure to the film or fabric to increase the moisture on the surface which is held by the fabric and to coalesce the surface fibers and reduce the porosity of the surface.

A prepreg having low water absorption, and having remarkably suppressed deterioration in insulation resistance over time, and further having excellent heat resistance, a metal foil-clad laminate using the prepreg, and a printed wiring board using the metal foil-clad laminate are provided. A prepreg of the present invention is obtained by impregnating or coating a base material (D) with a resin composition comprising: a naphthol-modified dimethylnaphthalene formaldehyde resin (A); an epoxy resin (B) having an epoxy equivalent of 200 to 400 g/eq.; and an inorganic filler (C).
