Zusammenfassung:	PURPOSE: To carry out a treatment by treating a combined fiber structure obtained by combining polyesters different in alkali dissolution rate coefficient under an alkali condition in the same bath in dissolution and dyeing, having an extremely shortened processing process, excellent in general purpose. CONSTITUTION: A polyethylene terephthalate as a slightly alkali-soluble polyester and a polyethylene glycol copolymer block polyether ester as a readily alkali- soluble polyester different in alkali dissolution rate coefficient by >=30 times or more are used, mixed by a static mixer and subjected to bicomponent spinning to give a conjugate fiber having a cross-sectional shape of the two kinds of the polyesters in plural laminated layers in a lamellar state. The conjugate fiber is twisted and used as warp and weft to weave a plain weave. The plain weave is not scoured, fed to a liquid flow dyeing machine, dissolved and dyed under alkalinity of
