Abstract: The invention provides a method of using fabric cutting scrap, which method comprises the steps of: (e) cutting the cutting scrap into flakes, (f) admixing the flakes to a polymer melt, (g) kneading the polymer melt with the flakes, so the flakes disintegrate into individual fibers, (h) molding the polymer melt with the admixed fibers into an intermediate article.

Abstract: Disclosed herein is a thermoplastic moulding composition including



a) from 50 to 96.95% by weight of polyamide containing aliphatic non-branched C10-12 building blocks, selected from polyamide 6.10 and mixtures of polyamide 6.10 with polyamide 6.12, polyamide 12.12, polyamide 11 and/or polyamide 12,
b) from 0 to 37% by weight of further polyamide different from component A);
c) from 3 to 30% by weight of polyamide-polyether block copolymer;
d) from 0.05 to 1.5% by weight of hindered amine light stabilizer,
e) from 0 to 1% by weight of sterically hindered phenol oxidation retarder;
f) from 0 to 20% by weight of further additives,
where the total of the percentages by weight of a) through f) is 100% by weight and the total of the percentages by weight of b) and c) is not more than 40% by weight.

Abstract: Disclosed herein is a polyamide composition (PC) including at least one polyamide (A) and at least one carbon black (B), where the surface layer of the at least one carbon black (B) includes not more than 2% by weight of oxygen, based on the total weight of the surface layer of the at least one carbon black (B), and where the weight of oxygen in the surface layer is measured by X-ray photoelectron spectroscopy at an X-ray penetration depth of 2 to 10 nm. Further disclosed herein are a process for producing the polyamide composition (PC), a process for producing a moulded article by forming the polyamide composition (PC), a moulded article including the polyamide composition (PC), and a method of using the at least one carbon black (B) in a polyamide composition (PC) for increasing the shrinkage of moulded articles made from the polyamide composition (PC).
