Title (EN) NONWOVEN COMPOSITE INCLUDING REGENERATED CELLULOSE FIBERS
(FR) COMPOSITE NON TISSÉ COMPRENANT DES FIBRES DE CELLULOSE RÉGÉNÉRÉES
Abstract: front page image
(EN)The present invention provides a soft, bulky, and absorbent hydroentangled nonwoven including regenerated cellulose fibers and staple or wood pulp fibers and a method of making the same that includes the steps of a) placing regenerated cellulose fibers on a forming surface; b) depositing staple or wood pulp fibers on the regenerated cellulose fibers; c) hydroentangling the regenerated cellulose fibers and the staple or wood pulp fibers together to form a hydroentangled composite; d) drying the hydroentangled composite; then, e) creping the hydroentangled composite with a frothed creping solution or dispersion.
(FR)La présente invention concerne un non-tissé hydrolié souple, volumineux et absorbant, comprenant des fibres de cellulose régénérées et des fibres discontinues ou de pâte de bois et son procédé de fabrication qui comprend les étapes consistant à a) placer des fibres de cellulose régénérées sur une surface de façonnage ; b) déposer des fibres discontinues ou de pâte de bois sur les fibres de cellulose régénérées ; c) hydrolier les fibres de cellulose régénérées et les fibres discontinues ou de pâte de bois ensemble pour former un composite hydrolié ; d) sécher le composite hydrolié ; puis e) crêper le composite hydrolié avec une solution ou dispersion moussée de crêpage.
