Abstract:
1. A nonwoven polymer breathable barrier material having 100% by weight content of a 100% monocomponent multi-lobal fiber having a cross section selected from the group consisting of tetra-lobal, penta-lobal, and hexa-lobal, wherein said cross section comprises separate multiple lobed portions extending from a centrally located portion of the fiber, said nonwoven polymer breathable barrier material useful for protecting crops selected from the group consisting of fruit, vegetable, and mixtures thereof from frost and insects, wherein the nonwoven polymer breathable barrier material reduces visible light transmittance by at least 10% compared to a nonwoven material that differs insofar as all the multi-lobal fiber is replaced with 100% monocomponent round fibers wherein fiber polymer chemical composition, fiber/filament denier, fabric basis weight, and overall material construction are approximately the same as the nonwoven material having the 100% multi-lobal fiber content except for cross-sectional shape of the multi-lobal fiber instead being round.
