Title
(EN) SELF-CRIMPED MULTI -COMPONENT FIBERS AND METHODS OF MAKING THE SAME
(FR) FIBRES À PLUSIEURS COMPOSANTS FRISANT TOUTES SEULES ET PROCÉDÉS DE FABRICATION DE CELLES-CI
Abstract
(EN)
Self-crimped multi -component fibers (SMF) are provided that include (i) a first component comprising a first polymeric material, in which the first polymeric material comprises a first melt flow rate (MFR) that is less than 50 g/10 min; and (ii) a second component comprising a second polymeric material, in which the second component is different than the first component. The SMF includes one or more three-dimensional crimped portions. Also provided are nonwoven fabrics comprising a plurality of SMFs. Methods of manufacturing SMFs and nonwoven fabrics including SMFs are also provided.
(FR)
L'invention concerne des fibres à plusieurs composants frisant toutes seules (SMF), qui comprennent (i) un premier composant comprenant une première matière polymère, la première matière polymère ayant un premier indice de fluidité à chaud (MFR) qui est inférieur à 50 g/10 min; et (ii) un second composant comprenant une seconde matière polymère, le second composant étant différent du premier composant. La SMF comprend une ou plusieurs parties frisées tridimensionnelles. L'invention concerne également des non-tissés comprenant une pluralité de SMF. L'invention concerne également des procédés de fabrication de SMF et des tissus non-tissés comprenant des SMF.
