SHEET AND SHEET MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/094595
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a composite sheet provided with all of water repellency, water resistance, transparency, and mechanical strength. The present invention relates to a sheet including a fiber layer and a coating layer on the fiber layer, wherein the fiber layer includes 60 mass% or more of fine fibrous cellulose, the fibrous fiber cellulose having a fiber width of 1000 nm or less, the haze of the sheet is 20% or less, and the water contact angle of a surface at the coating layer side of the sheet 30 seconds after distilled water has dropped thereon is 70 degrees or more.
