Abstract: 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.

Abstract: The present invention relates to novel polyvinyl alcohol non-woven films and fabrics which have been modified so as to have a breathable coalesced lower porosity surface polyvinyl alcohol layer attached to a fibrous polyvinyl alcohol layer by a transition layer. The fabrics are useful as clothing or wraps for inert articles.

Abstract: A process for producing a polyvinyl alcohol film or fabric having a modified non-porous surface which can be used to form disposable protective clothing, wraps, and articles similar to TYVEK® by impinging steam on at least one surface.

Abstract: A breathable protective garment or laminate for protection against chemical and/or biologic agents which contains one or more scrim layers which contain anti-microbial and/or anti toxic chemical agents. The garment or laminate is also self-decontaminating.

Abstract: A glazing unit comprising at least one monolithic glazing element bonded to at least one layer of a polymer having embedded therein at least one element of a fastening means adapted for mounting to a support structure. This construction provides and integrated connecting arrangement for the mechanical fastening of monolithic glazing units to a support structure to obtain a glazing assembly. A plurality of monolithic glazing units form glazing assemblies which when fixed in a planar array define a continuous smooth surface useful as exterior glazing facades. A clear gain is made, according to the invention is the simplicity of the installation of glass glazing facades to provide increased use in architectural designs. The invention is applicable to any glazing unit whether single, laminated, and/or multiple glazing elements are used.

Abstract: A method for preparing a transparent anti-spalling laminated article comprising a laminating layer which is an extruded copolymer having contiguous grooved or scored surfaces and transparent sheets of glass laminated to both surfaces of the layer:

Abstract: The invention relates to an anti-spalling laminated safety glass comprising a relatively thick front lamina, a back glass lamina having a thickness of 0.3 to 1.8 mm, and an intermediate resinous bonding layer, and glazing units formed therewith.
