PROBLEM TO BE SOLVED: To provide a method for producing high quality fabric improved in fastness and having 150 cm width while removing the possibility of causing defects such as mottled appearance, friction, wrinkle, crease, or the like due to piece dyeing. SOLUTION: When producing fabric using top dyed raw silk, the method of this invention is as follows: (1) making top dyed, sericin-fixed raw silk by dyeing both sericin and fibroin so as to have the same color after or with the fixation of sheath- like sericin into fibroin using a sericin fixation method before or after yarn doubling and before or after twining, where the fibroin is the core of silk fiber and is covered with sericin; (2) making fabric by weaving or knitting the top dyed, sericin-fixed raw silk; and (3) piece-degumming the fabric where the sericin of the top dyed, sericin- fixed raw silk is removed by degumming. The piece degumming process comprises (3') swelling the top dyed, sericin-fixed raw silk in the fabric by soaking the fabric into a hot water bath, (3") enzymatic-degumming by treating the fabric with enzyme in hot water bath to decompose sericin of the top dyed, sericin-fixed raw silk and making the fabric virtually made of fibroin alone. |
