Abstract
Nonwoven polymer materials and articles made therefrom. Materials of the invention include at least one nonwoven polymer web with at least one layer of at least about 50% by weight of a multi-lobal fiber. Materials and articles of the invention have improved properties, such as particle retention capacity, acoustic absorption, stiffness, crop color uniformity, and crop yield, when compared with nonwoven polymer materials and articles made with round fiber in place of all of the multi-lobal fiber.
