METHOD OF FORMING ELASTIC FIBERS AND STRETCHABLE ARTICLES CONTAINING SUCH FIBERS

A method comprises providing a resin comprising an olefin block copolymer; spinning the resin into one or more fibers; cooling the one or more fibers to below the solidification point of the resin; after cooling, stretching the one or more fibers to a nominal elongation of 50 to 900% to form one or...

Beschreibung
Zusammenfassung:	A method comprises providing a resin comprising an olefin block copolymer; spinning the resin into one or more fibers; cooling the one or more fibers to below the solidification point of the resin; after cooling, stretching the one or more fibers to a nominal elongation of 50 to 900% to form one or more stretched fibers; and relaxing the one or more stretch fibers to form one or more elastic fibers, and, optionally laminating the fibers to a flexible substrate. Articles comprising such elastic fiber(s) bonded to a nonwoven, can exhibit: a force at 50% elongation of less than 2 Newtons, a force at 100% elongation of less than 4 Newtons, a elongation at five Newtons for a 50 mm sample of at least 120%, and/or an unload force at 50% on a second cycle of less than 1.5 N/50 mm.
