Title:
FIBROUS STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2017/126358
Kind Code:
A1
Abstract:
The present invention provides a fibrous structure which is excellent in terms of water repellency and laundering durability, by mixing a slight amount of a fluorine compound with a compound containing no fluorine element with consideration of environmental problems.
The fibrous structure according to the present invention comprises fibers and, fixed to the surface thereof, at least one compound selected from the group consisting of hydrocarbon-based compounds and silicone-based compounds. This fibrous structure has water repellency, has a fluorine content, as determined by a combustion-tube decomposition/ion chromatography method, of 5-100 µg/g, and has a concentration of perfluorooctanoic acid and/or perfluorooctanesulfonic acid, as determined with a high-performance liquid chromatography/mass spectrometer (LC-MS), of less than 5 ng/g.
