PURPOSE: A low permeable fabric with high density is provided to make hard to form capillary tubes connected to each other as firm yarn is used and to make contain less moisture as the diameter of capillary tubes are small. CONSTITUTION: A low permeable fabric with high density has 50cc/cm^2/s or less permeability, 1500 or more of fabric cover factor, and 100 times or more of friction durable water repellency which are obtained by water repellent processing onto firm yarn with 5100 or more of twisted degree coefficient occupying a 50% or more of fabric surface area. The low permeable fabric with high density is composed of hydrophobic multi filament firm yarn with 7000-25000 of twisted degree coefficient occupying a 50% or more of the fabric surface area and is plain weave fabric, mat fabric, or twill fabric with 30-150 denier in thickness of the firm yarn, 0.1-3.5 denier of a single yarn of the firm yarn, and 2000 or more of fabric cover factor. |
