Abstract: Disclosed are fibers comprising a modified polyamide, such as a modified nylon-6, a modified nylon-6,6, or a modified nylon-5,6. The polyamide may be modified to contain a modified polyolefin, such as a maleated polyolefin. The disclosed fibers are hydrophobic and have surprising properties and benefits as compared to fibers having the same base polymer but without modification.
