Title:
SPUNBONDED NONWOVEN FABRIC AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/043322
Kind Code:
A1
Abstract:
The present invention provides a spunbonded nonwoven fabric that: has a smooth surface; is highly unlikely to cause a widthwise curl due to a difference between the states of front and back surfaces; has a superior film forming property of not allowing, at the time of casting of a resin solution, a bleed-through of the resin solution due to excessive permeation, a peel-off of a film material, or any other defect such as nonuniform film or pin hole due to fluffing, etc., of a base; and further exhibits film-adhesiveness that is strong enough to prevent the film material from peeling off after film formation.
