Non-woven materials from polyolefin-based fibres which have bulk and resilience comparable to polyester fibres are described herein, thus expanding the utility of polyolefin fibres and nonwovens to a plethora of industrial applications which previously excluded products based on polyolefin fibres due to their hitherto inadequate bulk or resilience. Control of polyolefin fibre characteristics such as the fibre/fibre friction, fibre crystallinity, draw ratio, or selection of the spin finish so as to comprise essentially of an aqueous emulsion of polysiloxanes render them suitable for preparing bulky and resilient nonwovens.
L'invention concerne des matières nontissées à partir de fibres à base de polyoléfine qui possèdent un volume et une résilience comparables aux fibres polyester, ce qui permet d'étendre l'utilisation des nontissés et des fibres en polyoléfine à un grand nombre d'applications industrielles, dont étaient antérieurement exclus les produits à base de fibres en polyoléfine, en raison de leur résilience ou volume inadéquats. La surveillance des caractéristiques des fibres en polyoléfine, telles que la friction fibre/fibre, la cristallinité des fibres, le taux d'étirage ou la sélection de l'ensimage de filature afin de comprendre essentiellement une émulsion aqueuse de polysiloxanes permet de les rendre plus appropriées à la préparation de nontissés résilients et volumineux.
