In accordance with at least selected embodiments, the present invention is directed to novel, improved, or modified porous membranes, fibers, porous fibers, products made from such membranes, fibers or porous fibers, and/or related methods of production, use, and/or the like. In accordance with at least certain embodiments, the present invention is directed to novel, improved, or modified microporous membranes or films, fibers, microporous fibers, materials or layers made from such membranes, fibers or porous fibers, and the like for use in textile materials, garments, products, and/or textile related applications. Microporous membranes, fibers, and/or microporous fibers are made of one or more copolymers, such as block or impact copolymers, or of at least one polyolefin combined with at least one copolymer as a means of improving the hand, drape, and/or surface coefficient of friction performance properties for use in textile garments, textile materials or textile related applications.
A novel, improved, or modified fiber, porous fiber, hollow fiber, or microporous fiber for use in at least one of materials, layers, composites, and textiles for textile products or other end use applications, the fiber, porous fiber, hollow fiber, or microporous fiber comprising at least one copolymer as a means to improve at least one characteristics or performance property selected from the group consisting of hand, drape, quietness, and surface coefficient of friction.
A novel, improved, or modified fiber, porous fiber, hollow fiber, or microporous fiber which comprises at least one polyolefin combined with at least one copolymer as a means to improve at least one characteristic or performance property selected from the group consisting of hand, drape, ‘quietness’ with movement, and surface coefficient of friction of the fibers in textile products or other end-use applications.
A novel, improved, or modified textile material, garment, or product made of a fibers, hollow fibers, or microporous fibers that are made of or comprise the following:
A battery separator comprising at least one microporous polyolefin membrane that comprises at least one polyolefin combined with at least one block or impact copolymer for improving membrane characteristics or performance properties, wherein the polyolefin including polypropylene, polyethylene, poly 1-butene, poly-4-methyl-1 pentene, polyhexene, polyoctene, and/or blends, mixtures, or combinations thereof, and wherein the block or impact copolymer comprises two or more polyolefins in mole fractions in a range of between 1% and 50%.
A battery separator comprising at least one microporous polyolefin membrane that comprises at least one of:
