Title:
NONWOVEN FABRIC OPENING RESPONDING TO STIMULATION
Document Type and Number:
Japanese Patent JP3795159
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain nonwoven fabric openable responding to stimulation that does not open in an acidic to neutral region but readily opens in an alkaline region by forming a shape with a number of fibers which can give nonwoven fabric and a specific binder responding to alkali.
SOLUTION: A number of fibers that can form nonwoven fabric and an alkali-responding binder comprising a cationic resin, for example, cationized cellulose, cationized dextran or cationized guar gum and an anionic resin, for example, carboxyl vinyl polymer, carboxymethyl cellulose (the content in the nonwoven fabric is preferably 0.1-20wt.%) are used to give the fibers a form thereby preparing non-woven fabric that opens responding to stimulation. The cationic resin and the anionic resin are preferably formulated at a weight ratio of 1/9-9/1.
