Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a spun yarn having a multi-layered structure having an innermost layer, a middle layer and an outermost layer and of which innermost or middle layer is constituted by a solvent-based PVA fiber capable of being removed by a dissolution, and providing a woven or a knitted fabric excellent in light weightiness, heat insulating property and soft feeling, and having a bulkiness, a flexibility and a pilling resistant property. SOLUTION: This spun yarn having a multi-layered structure has an innermost layer, a middle layer and an outermost layer and of which innermost or middle layer is constituted by a solvent-based PVA fiber capable of being removed by a dissolution. Further, by removing the solvent-based PVA fiber in the spun yarn having the multi-layered structure, e.g. a hollow spun yarn having 25-50% void ratio is obtained. Also, it is preferable to produce a pilling resistant woven or knitted fabric by using this hollow spun yarn.
