Side-by-side type spontaneous crimp fiber excellent in interfacial adhesion and crimp characteristics

摘要

The present invention relates to a side-by-side spontaneously crimped fiber having excellent interfacial adhesion and crimpability. In order to increase the bonding area of the interface between the positive and negative components, one component in the interface of the two components has circular hump or triangular hump Or the interface of the positive component is in a zigzag form.;In the present invention, the phase separation of the positive components does not occur well, and a high quality uniform spiral spontaneously spontaneously forming is expressed.
