Title:
FIBER STRUCTURE WITH WATER AND OIL REPELLENCY AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2013194335
Kind Code:
A
Abstract:

To provide a fiber structure that comprises a cellulosic fiber and/or a protein-based fiber with water and oil repellency and has high durability against washing and friction, and a method for producing the same.

The fiber structure comprises a cellulosic fiber and/or a protein-based fiber with water and oil repellency, and in the cellulosic fiber and/or the protein-based fiber, a fluorine-containing vinyl monomer is graft-polymerized at a ratio of 0.5 to 150 wt.%. The method for producing a fiber structure includes subjecting at least one fluorine-containing vinyl monomer having a C1-6 polyfluoroalkyl group as a component selected from a fluorine-containing olefin compound, a fluorine-containing acrylate compound, and a fluorine-containing methacrylate compound to a radical polymerization reaction with a cellulosic fiber and/or a protein-based fiber dispersed by using a nonionic surfactant with HLB of 7 to 18 in an aqueous dispersion.
