Title (EN) CELLULOSE ACETATE FIBERS IN NONWOVEN FABRICS
(FR) FIBRES D'ACÉTATE DE CELLULOSE DANS DES TISSUS NON-TISSÉS
Abstract:
(EN) Staple fibers and filament yarns formed from cellulose esters, such as cellulose acetate, are described herein, along with methods of making the fibers and their use in nonwoven fabrics and articles. The filament yarns and fibers described herein may be coated with at least one finish and, in some cases, may be coated with two or more finishes selected to enhance the properties of the fibers. Staple fibers as described herein may be used to produce nonwoven webs that are strong, soft, absorbent, and biodegradable, and may be used in wet or dry nonwoven articles for a variety personal care, medical, industrial, and commercial applications.
(FR) L'invention concerne des fibres discontinues et des fils de filaments formés à partir d'esters de cellulose, tels que de l'acétate de cellulose, ainsi que des procédés de fabrication des fibres et leur utilisation dans des tissus et des articles non-tissés. Les fils et fibres de filament de l'invention peuvent être revêtus d'au moins un apprêt et, dans certains cas, peuvent être revêtus d'au moins deux finitions sélectionnées pour améliorer les propriétés des fibres. Les fibres discontinues, selon l'invention, peuvent être utilisées pour produire des bandes non-tissées qui sont résistantes, molles, absorbantes et biodégradables, et qui peuvent être utilisées dans des articles non-tissés humides ou secs pour diverses applications de soins personnels, médicales, industrielles et commerciales.
