PROBLEM TO BE SOLVED: To obtain an India ink stain-resistant synthetic fiber fabric excellent in washing durability and abrasion durability and useful for carpets, etc., by impregnating a synthetic fiber fabric with an aqueous solution containing a fluorine-based water and oil repellent, etc., having hydrophilic segments and heat treating under a specific condition. ;SOLUTION: This India ink stain-resistant synthetic fiber fabric having ≥4th grade stain resistance SR to India ink stains judged by a gray scale as the stain in JIS L0805 after 20 times of repeating washing (a method according to JIS L0217-103) and ≥4th grade stain resistance SR to India ink stains judged by the gray scale as the stain in JIS L0805 after repeating abrasion (using an abrasion tester II described in JIS L0823, at 3000 times of abrasion under 500g load of an abrasion unit) is obtained by impregnating a synthetic fiber fabric from which adhered impurities are removed by prewashing or prerefining with an aqueous solution containing a fluorine-based water and oil repellent, a hydrophilic polyester-based resin, a nonhydrophilic fluorine-basedwater and oil repellent, and a crosslinking agent, and heat-treating at 140-180°C under dry heating after drying.;COPYRIGHT: (C)1997,JPO
