fabric was then dried as in example 1 the amount of the graft polymer of the resulting textile fabric was 0 5 by weight based on the total amount of the textile fabric a grafted polyester jersey was obtained in the same manner as in example 2 except that 2 ml of n vinyl 2 pyrrolidone were used as a polymerizable monomer the amount of the graft polymer of the resulting textile fabric was 0 8 by weight based on the total amount of the textile fabric a grafted polyester jersey was obtained in the same manner as in example 1 except that a sizing agent was not coated as a plasma reaction preventing layer the amount of the graft polymer of the jersey was 0 8 by weight based on the total amount of the textile fabric since the plasma device used in the present invention uses inner parallel flat electrodes it is impossible to protect one surface of a textile fabric by spreading the same on the electrode plates as described in the above mentioned document in which the drum type electrode is used accordingly in comparative example 2 the textile fabric was fixed on a curved glass plate instead of the electrode plates using a cotton yarn and the plasma treatment was conducted that is a grafted polyester jersey was obtained in the same manner as in example 1 except that the low temperature plasma treatment was conducted such that the above mentioned polyester.
