Abstract: A process for providing a material comprising a nonwoven layer of fibers is provided comprising: providing a material composition comprising: 90 to 98.7 wt. % of a recycled polyester polymer, 1 to 5 wt. % of a polyolefin polymer, and 0.3 to 5 wt. % of a compatibilizer based on the total weight of the recycled polyester polymer, the polyolefin polymer and the compatibilizer; melting the material composition; extruding the molten material composition through spinning holes in a spinneret to form extruded fibers; supplying the extruded fibers to form a nonwoven web of fibers; and consolidating the nonwoven web to obtain a material comprising a nonwoven layer of fibers.

Abstract: A nonwoven carrier for bituminous membranes, wherein the nonwoven includes organic polymer fibers and is consolidated with an aqueous binder, wherein the binder includes starch and polyvinyl alcohol, which includes up to 5 mol. % of other monomer units, wherein the binder does not include a crosslinker, and the binder does not include a filler.
