WATER- AND OIL-REPELLENT COMPOSITION HAVING LOW DYNAMIC SURFACE TENSION AND WATER- AND OIL-REPELLENT TREATMENT PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a water- and oil-repellent composition which may be used to treat a fiber or a cloth showing a water absorption speed, measured under a condition prescribed in JIS L1096 method C (sedimentation method) for water absorption speed, of ≥600 sec, and a treatment process using this. ;SOLUTION: A water- and oil-repellent composition contains a polymer containing a polymer unit of a compound having a polyfluoroalkyl group, a surfactant and an aqueous medium and has a dynamic surface tension of ≤50 mN/m.;COPYRIGHT: (C)2001,JPO
