Abstract
A process is provided for manufacturing a high quality cloth having a width of 150 cm or any width in which likelihood of occurrence of defects such as color shading, rub marks, wrinkles and creases due to fabric dyeing method is eliminated and color fastness is enhanced. A process for manufacturing a woven or knit fabric using yarn dyed silk comprises the steps of dyeing (step 3) sericin which covers the periphery of silk fibers and fibroin which is located inside thereof into the same color; making yarn dyed silk (step 4, 5) by doubling and twisting the dyed silk fibers; making a cloth (step 6) by weaving or knitting the yarn dyed silk; swelling (step 7) the yarn dyed silk which constitutes the cloth by dipping the cloth into hot water in a tub; and decomposing (step 8) sericin of the yarn dyed silk of the cloth with an enzyme in hot water in a tub.
