ABSTRACT:
The invention relates to a polyamide fiber whose polyamide is heavily branched. The branched polyamide preferably has 3-20 branches which are joined to a core molecule which is smaller than the polyamide arms. The arms originate preferably from functional groups which are identical and are preferably carboxyl groups. The polyamide is chosen from the group of polyamides which are produced by polycondensation of .alpha.,.omega.-aminocarboxylic acids or by ring-opening polymerization of lactams. Preferably, the polyamide is nylon-6. The properties of the fiber according to the invention are at least at the same level as those of fibers obtained by spinning linear polyamide. The spinning process for the fiber according to the invention is less susceptible to faults. Inter alia, the viscosity of the polyamide no longer changes during the spinning process.
