A fragrant sheath-core composite fiber suitable for bedding and having a cross-section including a sheath and a core including a hollow portion, wherein an aromatic perfume having a boiling point higher than 150°C. under normal pressure is incorporated and dipersed in an amount 0.1 to 10.0% by weigh

A fragrant sheath-core composite fiber suitable for bedding and having a cross-section including a sheath and a core including a hollow portion, wherein an aromatic perfume having a boiling point higher than 150°C. under normal pressure is incorporated and dipersed in an amount 0.1 to 10.0% by weight in a thermoplastic polymer constituting the core. The core component is preferably a polyethylene type polymer, and the sheath component is preferably a polyethylene terephthalate polymer. One of typical compositions of the aromatic perfume is an essential oil mixture including (1) 10 to 20% of lemon oil, (2) 5 to 15% of bergamot oil, (3) 2 to 8% of lavender oil, (4) 2 to 8% of lemongrass oil, (5) 2 to 8% of cedarwood oil and (6) 0.5 to 1.5% of jasmine absolute.
