摘要： A highly crimped conjugate fiber cheese package which is obtained by layering on a paper bobbin a conjugate fiber consisting of a plurality of single filament composed of polytrimethylene terephthalate components having different intrinsic viscosities and consisting of at least 90 mol% of a trimethylene terephthalate unit and no more than 10 mol% of another ester repeating unit and laminated to each other in a side-by-side type, the cheese package being characterized by satisfying the following conditions (1)-(4).
(1) The single filament composing the conjugate fiber has cross-sectional shape which is flat cross-section with a flatness of 1.1-3 as the ratio between the long axis and short axis.
(2) The developed crimp elongation of the conjugate fiber is 30-200%.
(3) The relationship between the contact area (compressed net area) S (cm 2 ) between the paper bobbin and conjugate fiber and the wound weight W (kg) satisfies the following formula (1): 2 ≤ W ≤ 0.02 ⁢ S
where 240 ≤ S ≤ 1000
(4) The package density of the conjugate fiber cheese package is 0.92-1.05 g/cm 3 .
