Title:
加湿用多層織物構造体
Document Type and Number:
Japanese Patent JP7178124
Kind Code:
B2
Abstract:
To provide a multilayer fabric structure for humidification which has high water retentivity, good air-permeability, and high transpiration capability of water into air, and which has a large void ratio, and small deformation of a three-dimensional shape even when used for a long time.SOLUTION: A multilayer fabric structure for humidification is formed of a multilayered woven structure obtained by weaving a high shrinkage yarn B as a warp yarn into a ground texture N composed of a weft yarn C and a low shrinkage yarn A as a warp yarn, and has at least one layer of a layer structure M in which a plurality of communicating voids G are arranged along one direction. The multilayer fabric structure for humidification has an apparent void ratio ranging from 93% or more to 99% or less, a water retention degree ranging from 150% or more to 350% or less, and an air-permeability ranging from 300 cm3/cm2/s or more to 550 cm3/cm2/s or less.SELECTED DRAWING: Figure 1
