Abstract: Disclosed herein is a biodegradable polyolefin fiber comprising a core formed of polyolefin and an oxide layer formed outside the core according to an embodiment of the present invention. According to the present invention, the polyolefin fiber is capable of having biodegradable properties by mixing raw materials and the biodegradable additive in a specific condition. In addition, the oxide layer is formed on the surface of the polyolefin fiber, thereby improving the initial oxo-biodegradation rate and reducing the biodegradation time.

Abstract: A system having a first polymer source and a spin beam in fluid communication with the first polymer source is provided. The spin beam includes a spinneret assembly having filament nozzles configured and arranged to extrude a plurality of filaments of a first polymer. A gas distribution plate is disposed downstream of the spinneret assembly, and includes a plurality of gas distribution slots that are configured and arranged to receive two or more corresponding filament nozzles of the spinneret assembly therein. A stream of gas is introduced into the plurality of slots to draw and attenuate the filaments extruded by the plurality of filament nozzles. The drawn and attenuated filaments are collected on a collection surface disposed downstream of the gas distribution plate to form a nonwoven fabric. A solid additive, such as pulp fibers may be blended with the filaments prior to collecting the filaments on the collection surface.
