Abstract: A composite nonwoven fabric can have a population of spunmelt fibers. The population of spunmelt fibers can include a first spunmelt fiber comprising a first polymer and a second polymer. The first polymer is a hydrophilic thermoplastic polymer comprising 65% (w/w) to 90% (w/w), inclusive, hydrophilic segments. The second polymer is a hydrophobic thermoplastic elastomer. The first spunmelt fiber comprises 20% (w/w) to 80% (w/w), inclusive, of the first polymer.

Abstract: A copolymer composition that includes a silicone copolymer, methods of making the composition, and articles that include the composition, wherein the copolymer composition includes a silicone copolymer having a backbone composition that includes: silicone segments in an amount of 5 wt-% to 40 wt-%, based on the total weight of the silicone copolymer; hydrophilic segments in an amount of 40 wt-% to 75 wt-%, based on the total weight of the silicone copolymer; and reinforcing segments in an amount of 5 wt-% to 30 wt-%, based on the total weight of the silicone copolymer, wherein the reinforcing segments are derived from the reaction of one or more chain extenders with one or more multi-functional isocyanates, multi-functional carboxylic acids, multi-functional anhydrides, multi-functional esters, and/or multi-functional acid halides; wherein the silicone segments, hydrophilic segments, and reinforcing segments are connected through urea, urethane, amide, and/or oxamide linkages; wherein the hydrophilic segments and the reinforcing segments are present in a weight ratio of 1.8:1 to 8:1; and the hydrophilic segments and the silicone segments are present in a weight ratio of 1.3:1 to 4.5:1.
