PURPOSE:To impart a silk fabric with durable wrinkle-proofness, shrink- proofness, light resistance and chemical resistance by impregnating an alcohol solution containing a polyfunctional epoxy compound and a specific alkali metal alcoholate into a silk fabric, drying the fabric and curing the product with steam. CONSTITUTION:An isopropanol solution containing a polyfunctional epoxy compound and an alkali metal alcoholate of formula ROM (R is <=4C alkyl; M is Na or K) is prepared beforehand. The alcohol solution is applied to a silk fabric at a squeezable liquid ratio of 70-110% by padding and preliminarily cured at <=80 deg.C. The dried fabric is cured with saturated steam at about 100 deg.C for 5-10min. |
