Multisegment fiber of polyamide-polyester is isolated into a great number of microfibers by chemical and physical treatment. One of the two fiber-formable polymers makes 4 wedge-shapes which are branched radially from a center in a cross section of the multifilament and the other is disposed alternately between the wedges in order to shield the circumference of the cross section of the multifilament. |
