Title (EN) NONWOVEN FABRICS COMPRISING POLYLACTIC ACID HAVING IMPROVED STRENGTH AND TOUGHNESS
(FR) TISSUS NON TISSÉS COMPRENANT DE L'ACIDE POLYLACTIQUE QUI POSSÈDENT UNE RÉSISTANCE ET UNE TÉNACITÉ AMÉLIORÉES
Abstract:
(EN) Nonwoven fabrics having a plurality of fibers that are bonded to each other to form a coherent web, wherein the fibers comprise a blend of a polylactic acid (PLA) and at least one secondary alkane sulfonate are provided. The nonwoven fabrics exhibit increased tensile strengths, elongation and toughness.
(FR) La présente invention concerne des tissus non tissés comprenant une pluralité de fibres qui sont liées les unes aux autres pour former une bande cohérente, les fibres comprenant un mélange d'un acide polylactique (PLA) et d'au moins un sulfonate d'alcane secondaire. Les tissus non tissés présentent une résistance à la traction accrue, un allongement accru et une ténacité accrue.
