Abstract: The invention provides a polyester bicomponent staple fiber comprising poly(trimethylene terephthalate) and at least one polymer selected from the group consisting of poly(ethylene terephthalate), poly(trimethylene terephthalate), and poly(tetramethylene terephthalate) or a combination of such members, said bicomponent staple fiber having: a) a scalloped oval cross-section shape having an aspect ratio a:b of about 2:1 to about 5:1 wherein 'a' is a fiber cross-section major axis length and 'b' is a fiber cross- section minor axis length; b) a polymer interface substantially perpendicular to the major axis; c) a cross-section configuration selected from the group consisting of side-by- side and eccentric sheath-core; d) a plurality of longitudinal grooves; and e) a groove ratio of about 1.05:1 to about 1.9:1. Additionally, the invention provides a spun yarn comprising cotton and the polyester bicomponent staple fiber of the invention, as well as fabrics and garments comprising the spun yarn of the invention.

Abstract: The invention provides upholstery stretch slipcovers (20, 30) comprising a fabric having sufficient elastic recovery force that the cover requires no additional fabric having greater elastic recovery force than said first fabric to hold the stretch cover in place and to maintain the substantial absence of surface wrinkles in normal use. The stretch slipcovers (20, 30) are particularly useful for chairs having separate back and seat cushions. The invention further provides a method for replacably upholstering a resilient cushion.

Abstract: Included are segmented polyurethane elastic fibers or spandex fibers, capable of bonding to polymer fiber such as nylon or polyamide fibers, in addition to bonding to itself, for apparel textile applications. More particularly the invention relates to bicomponent spandex fibers, with a heat resistant core and a heat sensitive sheath, spun from polymer solutions. The nylon fabrics containing such spandex fibers have enhanced stretch performance and improved surface appearance after heat treatment to activate the fusing and bonding between nylon fibers and spandex fibers.
