Abstract:
1. A stretch fabric comprising: (A) an ethylene/α-olefin block interpolymer, wherein the ethylene/α-olefin interpolymer before crosslinking is characterized by one or more of the following characteristics: wherein the CRYSTAF peak is determined using at least 5 percent of the cumulative polymer, and if less than 5 percent of the polymer has an identifiable CRYSTAF peak, then the CRYSTAF temperature is 30° C.; or (2) a storage modulus at 25° C., G′(25° C.), and a storage modulus at 100° C., G′(100° C.), wherein the ratio of G(25° C.) to G′(100° C.) is in the range of about 1:1 to about 9:1; and (B) a crosslinked cellulosic material; wherein the fabric has a stretch of at least 8 percent measured according to ASTM D3107, and wherein the fabric has a durable press rating of at least 3.0 after 5 times washing using AATCC-124 or Marks and Spencer P134.
