Title
(EN) MULTIL-LOBAL FIBER CONTAINING NONWOVEN MATERIALS AND ARTICLES MADE THEREFROM
(FR) FIBRE MULTILOBEE RENFERMANT DES MATERIAUX NON TISSES ET ARTICLES PRODUITS A PARTIR DE CES MATERIAUX
Abstract
(EN)
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.
(FR)
La présente invention concerne des matériaux polymères non tissés et des articles produits à partir de ces matériaux. Les matériaux de l'invention comprennent au moins une bande polymère non tissée composée d'au moins une couche contenant au moins 50 % en poids d'une fibre multilobée. Les matériaux et les articles de l'invention présentent des propriétés améliorées, telles que la capacité de rétention des particules, l'absorption acoustique, la rigidité, l'uniformité de la couleur de la récolte et le rendement de la récolte, si on les compare avec des matériaux et des articles polymères non tissés fabriqués à partir de fibres rondes au lieu de fibres multilobées.
