Abstract
To provide a wound yarn package and a method for manufacturing the same in which even if sea-island type fibers are wound around a bobbin one by one by a traverse mode, cob-webbing and curling are less likely to occur, and the variation in the heat shrinkage rate between layers constituting the yarn layer is reduced. When winding sea-island type fibers with a fineness of 100 to 6400 dtex around a bobbin one by one by a traverse mode to form a yarn layer, each yarn constituting the n-th yarn layer is wound at a position 0 to x mm away from each yarn constituting the (n−1)-th yarn layer, with the yarn width of the sea-island type fiber being taken as x (mm), to fabricate a wound yarn package
