PROBLEM TO BE SOLVED: To provide a method for producing a polyester knitted or woven fabric having excellent deep dyeing effects. SOLUTION: Fibers, comprising a mixture of 2-30 pts.wt. thermoplastic aliphatic polyester component with 98-70 pts.wt. thermoplastic polyester component, having a lower solubility in an aqueous solution of an alkali than that of the component (A) and good in fiber-forming properties or the mixture and the component (B), in which the mixture occupies at least a part of the fiber surface, are used to constitute a woven or a knitted fabric. The resultant woven or knitted fabric is then treated with an alkali to dissolve and remove at least a part of the component (A). The obtained woven or knitted fabric is subsequently dyed. |
