Abstract
The present invention relates to a fiber, which includes:2 to 95% by weight, based on the total weight of the fiber, of at least one block copolymer, which includes:at least one polymer block (A) that includes 50 to 100% by weight of olefinic monomer units, based on the total weight of the block copolymer; andat least one polymer block (B) that includes 0.1 to 100% by weight of (meth)acrylic monomer units, based on the total weight of the block copolymer. Other embodiments of the invention include fibrous structures, non-woven fabrics, leather-like sheet materials, and dyed articles, which include the above-described fiber, and processes of making the above-described fiber. The present invention also relates to a composite fiber, and fibrous structures, non-woven fabrics, leather-like sheet materials, and dyed articles, which includes the above-described composite fiber, as well as processes for producing the above-described composite fiber.
