Title
(EN) SPACER FABRICS AND METHODS OF MAKING THE SAME
(FR) TISSUS DE SÉPARATION ET PROCÉDÉS DE FABRICATION DE TELS TISSUS DE SÉPARATION
Abstract
(EN) In one aspect, methods of making a spacer fabric are described herein. In some embodiments, a method comprises knitting a first yarn or fiber and a second yarn or fiber to form a knit structure, wherein the knit structure comprises a plurality of concave portions in facing opposition to a plurality of convex portions. Further, the concave portions and the convex portions together define void spaces having a substantially double convex cross section. In some cases, the method further comprises heating the knit structure at a temperature sufficient to cause the second yarn or fiber to shrink in at least one dimension. Additionally, the second yarn or fiber shrinks more than the first yarn or fiber during the heating step. Moreover, in some instances, heating the knit structure increases a size of the void spaces of the knit structure, particularly in a thickness direction of the fabric.
(FR) Selon un aspect, la présente invention concerne des procédés de fabrication d’un tissu de séparation. Selon certains modes de réalisation, un procédé comprend le tricotage d'un premier fil ou d'une première fibre et d'un second fil ou d’une seconde fibre pour former une structure tricotée, la structure tricotée comprenant une pluralité de parties concaves placée en opposition face à une pluralité de parties convexes. En outre, les parties concaves et les parties convexes définissent ensemble des espaces vides ayant une section transversale convexe sensiblement double. Dans certains cas, le procédé comprend en outre le chauffage de la structure tricotée à une température suffisante pour amener le second fil ou la seconde fibre à se rétracter dans au moins une dimension. De plus, le second fil ou la seconde fibre se rétracte plus que le premier fil ou la première fibre pendant l'étape de chauffage. De plus, dans certains cas, le chauffage de la structure tricotée augmente la taille des espaces vides de la structure tricotée, en particulier dans une direction d'épaisseur du tissu.
