Title
(EN) WATER-ABSORBING STRETCH KNIT FABRIC
(FR) TRICOT EXTENSIBLE ABSORBANT L'EAU
(JA) 吸水性ストレッチ編地
Abstract
(EN)
A water-absorbing stretch knit fabric comprising a multilayer structure knit fabric composed at least of two layers of surface layer and backside layer wherein the surface layer contains a conjugated fiber multifilament yarn having two types of polyester polymers bonded together in a side-by-side fashion along the direction of fiber length in an amount of 30 % or more, characterized in that the knit fabric exhibits such a water absorbency that the surface layer to backside layer ratio of absorbed water retention is 2 or higher while the surface layer to backside layer ratio of absorbed water diffusion area is 2 or higher, and that the knit fabric exhibits, in the longitudinal and lateral directions, an average extension ratio of 55% or higher and an average extension recovery ratio of 60% or higher.
(FR)
Tricot extensible absorbant l'eau comprenant un tricot ayant une structure multicouche constitué d'au moins deux couches comprenant une couche de surface et une couche d'envers, ladite couche de surface contenant un fil multifilament de fibres conjuguées ayant deux types de polymères de polyester collés ensemble côte à côte dans la direction de la longueur de la fibre en quantité supérieure ou égale à 30 %, caractérisé en ce que ledit tricot présente une absorbance de l'eau telle que le rapport de la rétention de l'eau de la couche de surface sur celle de la couche d'envers est supérieur ou égal à 2 alors que le rapport de la zone de diffusion de l'eau absorbée de la couche de surface sur celle de la couche d'envers est supérieur ou égal à 2 et en ce que ledit tricot présente, dans la direction longitudinale et dans la direction perpendiculaire, un taux d'allongement moyen supérieur ou égal à 55 % et un taux moyen de récupération après allongement supérieur ou égal à 60 %.
(JA)
 本発明の吸水性ストレッチ編地は、表面層と裏面層の少なくとも2層からなる多層構造編地であって、該編地の表面層が、2種類のポリエステル重合体が繊維長さ方向に沿ってサイドバイサイド型に貼り合わされた複合繊維マルチフィラメント糸を30%以上含んでいる編地であって、該表面層の裏面層に対する吸水表裏保水率比が2倍以上で、かつ、吸水表裏拡散面積比が2倍以上である吸水性を有し、かつ、該編地のタテ・ヨコ方向の平均伸長率が55%以上、平均伸長回復率が60%以上であることを特徴とするものである。
