Abstract:
The invention relates to a method for using cutting remainders of fiber structures, comprising the following steps: (a) cutting the cutting remainders to flakes, (b) admixing the flakes to a polymer melt, (c) kneading the polymer melt containing the flakes such that the flakes disintegrate into individual fibers, and (d) shaping the polymer melt containing the admixed fibers to a semi-finished product.
