PROBLEM TO BE SOLVED: To provide the cheese-like package of a polyester false twisted yarn without tight winding, shape losing and difference in dyeability or physical property between the innermost and surface layers, and favorable in unwindability when knitting or weaving.SOLUTION: There is provided the cheese-like package of a polyester false twisted yarn in which the hardness of a surface layer is lower than 75°; in each end face hardness measured in three positions obtained by quartering the innermost and outermost layers, the increasing rate in adjacent hardness is 2 to 10% of an inner layer side hardness; and the taper angles of the inner and outer layers in the end face of a package are 0±5° and 24±10°, respectively, and the angle gradually increases from the inner layer toward the outer layer.SELECTED DRAWING: Figure 1 |
