Abstract
Provided is a fiber structure having high adhesion suppressibility against aqueous soil and oily soil and soil removability in washing. A soil resistant fiber structure includes a resin film on at least a part of a fiber surface, the resin film containing polyvinyl alcohol and a fluorine-based oil-repellent resin having a hydrophilic component, the fiber structure having a water repellency degree of 2 or less as measured by a spray test in accordance with JIS L-1092, and an oil repellency degree of 2 or more as measured in accordance with AATCC 118 method. The fluorine-based oil-repellent resin is preferably a fluorine-based oil-repellent resin containing a polyoxyalkylene group. The polyvinyl alcohol preferably has an average polymerization degree of 200 to 1500.
Claims18
A soil resistant fiber structure comprising a resin film on at least a part of a fiber surface, the resin film containing polyvinyl alcohol and a fluorine-based oil-repellent resin having a hydrophilic component, the soil resistant fiber structure having a water repellency degree of 2 or less as measured by a spray test in accordance with ES L-1092, and an oil repellency degree of 2 or more as measured in accordance with AATCC 118 method.
A method for producing a soil resistant fiber structure, the method comprising treating a fiber structure with a treatment liquid containing polyvinyl alcohol and a fluorine-based oil-repellent resin having a hydrophilic component.
