Abstract: The invention relates to nonwoven fabrics containing polymeric multiple component fibers which include a core component and a plurality of wing components attached to the core. The polymeric core component has an elasticity that is greater than the elasticity of at least one of the wing polymeric components. The fibers assume a spiral twist configuration in which the plurality of wings substantially spiral about the core. In a preferred embodiment, the nonwoven fabrics have elastic stretch and recovery properties with a textile-like hand.

Abstract: Knit fabrics and socks made therefrom and a process for producing such articles are disclosed, The fabrics are constructed from blended yarns containing at least 30% by weight high tensile nylon, which imparts abrasion resistance, and at least one companion fiber, which is chosen to confer a specific desirable attribute. Exemplary is the fabric constructed from blended yarn containing high tensile nylon staple and polyester staple, the fabric being particularly useful for the manufacture of socks demonstrating improved durability and moisture management.

Abstract: A pile article having a support strand for attachment to multifilament yarn to form a velour-like pile having loosely entangled filaments in spaced apart monolithic pile rows, a helically wound package of oriented pile articles for shipping and storage, and a pile surface structure comprising pile articles arranged in spaced apart rows on a substrate to form a pile surface that may be flat or moldable, and a method for making a pile surface structure by embedding the pile articles into the backing substrate. The pile surface structures may be usefully employed in automobile mats, carpets and panels.

Abstract: This invention provides moisture stable tuftstring carpet assemblies. The pile surface structure comprises a moisture stable backing substrate, a plurality of elongated pile articles each comprising an elongated, moisture stable support strand having bonded thereto a plurality of "U" shaped bundles of multifilament yarn. The pile articles are bonded to the backing substrate. Different backing substrates and support strands may be used.

Abstract: Apparatus for enlarging the analytical capability of a photometric analyzer for segregating a first preselected analytical radiation wavelength band for passage through a first sample cell and segregating a second preselected analytical radiation wavelength band for passage through a second sample cell, after which emergent radiations from both sample cells are directed to a common radiation detector.
