Title:
ROLL-TYPE POLYIMIDE FABRIC USING SEPARATION MEMBRANE, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2019/156302
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a roll-type polyimide fabric using a separation membrane. The present invention supports, with a separation membrane, the lower end of a fabric used as a base material and then coats the upper surface of the base material placed above the separation membrane with a polyimide varnish in an even thickness, thereby preventing rolling and breaking of the fabric when coating with the polyimide varnish and enabling the thickness of the polyimide varnish to be easily adjusted and the whole width of the base material to be coated with the polyimide varnish. Also, the present invention can provide the roll-type polyimide fabric using a separation membrane which is made usable by graphtizing a fabric or is used as an alternative for a polyimide film, the polyimide fabric enabling the thickness of the polyimide varnish coating to be easily adjusted by having the varnish diffuse along the surface of the separation membrane supporting the base material and maintain a smooth surface overall when the polyimide varnish being coated on the base material passes through the base material of the fabric and moves downward. Furthermore, the whole width of the base material can be coated with the polyimide varnish, and, thereby, productivity is greatly increased.
