Title (EN) NON-WOVEN FABRIC SHEET FOR AGRICULTURAL USE
(FR) FEUILLE DE TISSU NON-TISSE A USAGE AGRICOLE
Abstract:
(EN) A non-woven fabric sheet for agricultural use, which has been rendered hydrophilic by applying a surfactant on at least part of the surface of a hydrophobic non-woven fabric. This treatment serves to provide the water passage through which water passes from the surface to the back side of the fabric, and imparts a water retentivity of 150 to 300 wt. %. The water passage permits rainwater to rapidly pass there-through from the surface to the back side, and the low water retentitivity prevents an increase in weight of the fabric due to water retention .
(FR) Feuille de tissu non-tissé à usage agricole, rendue hydrophile par application d'un tensio-actif sur au moins une partie de la surface du tissu non tissé hydrophobe. Ce traitement permet le passage de l'eau, grâce à quoi l'eau passe de la surface à l'envers du tissu, et confère un pouvoir de rétention allant de 150 à 300 % en poids. Le passage de l'eau permet à l'eau de pluie de passer à travers celui-ci rapidement, de la surface à l'envers, et le faible pouvoir de rétention d'eau empêche une augmentation du poids du tissu due à la rétention d'eau.
