Abstract: A crimper (1) includes: a pair of nip rolls (2) including respective peripheral surfaces between which conveyed filaments (11) pass; a first member (6) and a second member (7) including contact surfaces (6a, 7a) that come into contact with the filaments and being disposed on a downstream side of the pair of nip rolls in a conveyance direction of the filaments, the respective contact surfaces being disposed facing each other across a gap; and a pressing member (5) disposed in the gap and configured to press the filaments toward the contact surface of any of the first member and the second member. A surface roughness Ra of the contact surfaces is set to a value in a range of from 0.1 to 1.0.

Abstract: The present invention provides a package of a filter tow bale made of cellulose acetate packed with a packing material in a non-hermetic state, which can be stacked in multistage and in which tows in the same bale can be uniformly maintained. The package of the filter tow bale made of cellulose acetate is packed with the packing material in the non-hermetic state, in which the filter tow bale is tightened with the packing material in the package, the filter tow bale has a cubic shape or a rectangular parallelepiped shape with 800 to 1,400 mm in length, 800 to 1,150 mm in width, and 800 to 1,100 mm in height, and a packing initial pressure between a top surface of the filter tow bale and the packing material is 6.3 kPa or less.
