Beschreibung
Zusammenfassung:	The invention discloses a high-shrinkage polyester sea-island fiber and a preparation method and application thereof, and relates to the technical field of superfine fibers, high-shrinkage polyester HSPET is used as an island component, modified copolyester UFC is used as a sea component, the theoretical filament number of the island component is less than 0.1 dtex, the sea component contains a crystallization inhibitor, and the mass ratio of the sea component to the island component is (15-20): (85-80); the boiling water shrinkage of the sea-island fiber and the density of the needle-punched non-woven fabric prepared from the sea-island fiber are improved, so that the sea component UFC in the sea-island fiber has the characteristics of high macromolecular orientation degree and small crystallinity as the island component HSPET. 本发明公开了一种高收缩聚酯海岛纤维及其制备方法和应用，涉及超细纤维技术领域，以高收缩聚酯HSPET为岛组分，以改性共聚酯UFC作为海组分，其中，岛组分的理论单丝纤度＜0.1dtex，海组分中含有结晶抑制剂，所述海组分和岛组分的质量比为15～20:85～80；本发明提高了海岛纤维的沸水收缩率和由该海岛纤维制备的针刺无纺布的密度，使海岛纤维中海组分UFC与岛组分HSP
