摘要:
Polymeric structures produced with a controlled number and distribution of small, closed cells. The polymeric structures are characterized by an opaque, whitening appearance attributed, at least in part, to the distribution of closed cells and thus, at least in part, to light scattering resulting from the distribution of small, closed cells or voids. The light scattering thus provides an enhanced whitening effect. The whitening effect may be uniform or non-uniform along the length and width of the structure.

摘要:
Provided herein are various flexible sheet-like substrates that are lightweight, rupture or burst resistant, and suitable for use in constructing a variety of structures used in fluid-containment, especially gas containment, and other applications, and the processes by which such composites can be fabricated. In the most general case, the composites of this disclosure are comprised of a woven textile fabric to which has been laminated a flexible film. Two principal embodiments are disclosed: a first embodiment without a reinforcing layer, and a second embodiment with a structurally robust, bias-oriented reinforcing layer, preferably interposed between the fabric and the film.
摘要:
The present process involves applying a plasticizer- or solvent-containing solution to a subject fabric, preferably under heated conditions, and then mechanically abrading the treated fabric. The process results in the rearrangement of the fabric structure, as a plurality of branched fibrils are created along the length of the yarn filaments. Thus, the molecular weight of the fabric's yarns and, therefore, the strength of the polymer chains are maintained. Fabrics made from this process, which exhibit a silk-like hand that results from the presence of multiple integral fibrils and branched fibrils, are also provided.
