Thin-film type highly moisture-transmissive fiber sheet

Abstract

A thin film-type high moisture transferable fiber sheet includes a thin film coating layer formed on one side of the hydrophilic fiber sheet, in which the thin film coating layer is formed such that a hydrophobic coating agent is coated on a portion of the one side of the fiber sheet in a thin film-type.

1 . A thin film-type high moisture transferable fiber sheet comprising a thin film coating layer on one side of a hydrophilic fiber sheet,
 wherein the thin film coating layer comprises a hydrophobic coating agent coated on a portion of the one side of the fiber sheet in a thin film-type.   
     
     
         2 . The fiber sheet according to  claim 1 , wherein the thin film coating layer has a thickness of 20 nm to 80 nm. 
     
     
         3 . The fiber sheet according to  claim 1 , wherein the hydrophobic coating agent comprises a silicone-based water repellent and a transparent binder. 
     
     
         4 . The fiber sheet according to  claim 1 , wherein the hydrophobic coating agent is applied to 70% to 95% of a surface area of the one side. 
     
     
         5 . The fiber sheet according to  claim 1 , wherein the thin film coating layer has a gap of 0.5 mm to 5 mm in which the hydrophobic coating agent is not coated. 
     
     
         6 . The fiber sheet according to  claim 1 , wherein the hydrophobic coating agent constitutes the thin film coating layer in the form of dots or stripes. 
     
     
         7 . The fiber sheet according to  claim 5 , wherein a color difference occurs between the thin film coating layer and the gap when moisture is absorbed.
