  • Olefin block compositions for heavy weight stretch fabrics
    Patent number: 7928022
    Abstract: Heavy weight stretch fabrics comprising ethylene/?-olefin interpolymer are described. The fabric often has a weight of at least 10 ounces per square yard measured according to ASTM 3776 and has a stretch of at least 10 percent measured according to ASTM D3107. These fabrics exhibit excellent chemical, resistance (for example chlorine or caustic resistance) and durability, that is they retain their shape and feel over repeated exposure to processing conditions, such as stone-washing, dye-stripping, PET-dyeing and the like, and industrial laundry conditions.
