Beschreibung
Zusammenfassung:	The present invention provides a composite fiber having a high surface area and flexibility and a method for manufacturing the same, and a substrate containing the composite fiber and a method for manufacturing the same. The composite fiber contains a first component and a second component, and has a maximum diameter and a circumference. The first component has a central portion and a plurality of extension portions. A maximum length of the central portion is less than three quarters of the maximum diameter. The first component is in an amount of 50 wt % to 95 wt %, based on the total weight of the composite fiber. The second component has a plurality of outer portions disposed between two extension portions, and the second component is in an amount of 5 wt % to 50 wt %, based on the total weight of the composite fiber.
