PURPOSE: To prepare a light raised product having soft and bulky feelings without decreasing the strength by treating a textile structure consisting of a polyester fiber and a cellulose-based fiber with a mixture solution of an alkali with α-amylase and reducing the weight by cellulase.

CONSTITUTION: This method for a light raised finish processing is to lay an orthoblended plain wave consisting of warp polynosic rayon spun yarns and weft polyester multifilaments in a fluid stream dying machine, treat the weave in a treating solution comprising sodium hydroxide and α-amylase enzyme and having <pH11 under no stretch or a low stretch at ≥100°C, wash the weave with hot water and water to carry out desizing and relaxing or desizing and untwisting relaxing at the same time, then treat the weave with cellulase enzyme to reduce the weight and obtain the objective light raised product.
