FIBER OBTAINABLE FROM OR UNDERSTANDING A PROPILENE INTERPOLYMER / <244> -OLEFINE, FIBER OBTAINABLE FROM OR UNDERSTANDING A PROPILENE INTERPOLIER AND A <244> -OLEFIN OF C ~ 2 ~ OR C ~ 4 ~ -C ~ 20 ~ CLOTH, Yarn AND METHOD FOR MANUFACTURING A FIBER. A fiber is obtainable from or comprises a propylene / β-olefin interpolymer characterized by an elastic recovery, R ~ and,, in percent to 300% strain and 1 cycle and a density, d, in grams / cubic centimeter, wherein the elastic recovery and density satisfy the following ratio: R e => 1481-1629 (d). Such an interpolymer may also be characterized by other properties. The fibers made with the interpolymer have a relatively high elastic recovery and a relatively low friction coefficient. If desired, the fibers may be crosslinked. Woven and non-woven cloths may be made from such fibers. |
