Abstract

The present invention relates to a composite fiber consisting of two components, for example, such as a polyamide and a polyester, and to a multi-segment fiber wherein the two components thereof can be separated into a plurality of microfibers by chemical and physical treatments. Particularly, the invention relates to a composite fiber having low loss of weight in a chemical treatment and which can easily be separated into outer and inner components. After separation the composite fiber provides excellent performance.
