【発明の名称】ポリ(メチルビニルエーテル―コ―マレエート)とポリオールとで変性されたセルロース繊維
Document Type and Number:
Japanese Patent JP2974771
Kind Code:
B2
Abstract:
Disclosed is a fiber comprising, chemically bonded together, (a) a conventional cellulosic fiber, such as a Kraft fiber or a chemithermomechanical pulp fiber; (b) poly(methyl vinyl ether-co-maleate) copolymer, such as the acid form of a 1:1 (molar) poly(methyl) vinyl ether-co-maleate) copolymer, preferably having number average molecular weight of about 67,000-80,000; and (c) a polyol, such as polyethylene glycol; also disclosed are methods for making such fibers, especially evaporatively depositing an intimate mixture of the copolymer and polyol on the discrete fiber followed by thermally crosslinking at specific temperatures for limited periods; absorbent paper which can be made by wet-laying the fiber, especially in admixture with conventional fiber; and derivative paper structures, such as multi-ply disposable absorbent towels.
