Title (EN) DEGRADABLE POLYMER FIBERS; PREPERATION; PRODUCT; AND METHODS OF USE
(FR) FIBRES POLYMERES DEGRADABLES; PREPARATION; PRODUIT; ET PROCEDES D'UTILISATION
Abstract:
(EN) The present invention relates to a fibrous material which includes a plurality of polylactide containing fibers. The plurality of polylactide containing fibers can be considered low shrinkage or high shrinkage. The plurality of polylactide containing fibers are considered low shrinkage fibers if they provide a boiling water shrinkage propensity of less than about 20 %. The plurality of polylactide containing fibers are considered high shrink fibers if they provide an average fiber boiling water shrinkage propensity of greater than about 10 % and a heat of fusion of less than about 25 J/g. The invention additionally relates to the use of an extrusion process to provide low shrinkage fibers and high shrinkage fibers. The invention futher relates to the use of these fibers in desirable products.
(FR) La présente invention a trait à une matière fibreuse comportant plusieurs fibres contenant du polylactide. Les fibres contenant du polylactide peuvent être considérées comme fibres à faible retrait ou à retrait élevé. On considère que les fibres contenant du polylactide sont des fibres à faible retrait si leur aptitude au retrait dans l'eau bouillante est inférieure à environ 20 %. On considère que les fibres contenant du polylactide sont des fibres à retrait élevé si elles présentent une aptitude moyenne au retrait dans l'eau bouillante supérieure à environ 10 %, et une chaleur de fusion inférieure à environ 25J/g. L'invention a en outre trait à l'utilisation d'un procédé d'extrusion permettant d'obtenir des fibres à faible retrait et des fibres à retrait élevé. De plus, l'invention concerne l'utilisation de ces fibres dans des produits voulus.
