Abstract
A spontaneously degradable fiber excellent in bulkiness, softness, stretchability and feeling, which comprises (A) a low heat-shrinkable fiber component comprising a high crystalline aliphatic polyester and (B) a high heat-shrinkable fiber component comprising an aliphatic polyester, e.g., a low crystalline or non-crystalline aliphatic polyester, and a block copolymer or a mixture the main component of which is an aliphatic polyester and which comprises a high-melting component and a low-melting component. Further, fibers excellent in self-crimpability or self-adhesion property and dividable fibers are obtained by suitably combining the fiber components (A) and (B) to form conjugated fibers or composite yarns.
