浸水指向性を有する繊維シート
Document Type and Number:
Japanese Patent JP7110522
Kind Code:
B2
Abstract:
To be able to exert water-holding properties, and water-transmitting properties by providing a constitution having hydrophilic characteristics (water immersion characteristics), and having specific direction characteristics (directivity) with regard to the water immersion characteristics, and to use in such an application that a sheet is laid in a planting ground using the water-holding properties, and the water-transmitting properties.SOLUTION: The fiber sheet has a main body layer 2 comprising a nonwoven fabric. The main body layer 2 is constituted by arranging a plurality of immersion function bands 5 which is relatively coarse in fiber density, and a plurality of exudation faction bands 6 which is dense in a band length direction respectively in parallel, and in a band width direction in alternate shifts. In the nonwoven fabric forming the main body layer 2, fiber directions are arranged in a single direction while agreeing in a band lengthwise direction of the immersion function band 5 and the exudation function band 6.SELECTED DRAWING: Figure 1
