Beschreibung
Zusammenfassung:	A polyamide composition, which includes an optical brightener together with either an antimicrobial agent or anti-oxidant stabilizer, or both, is suitable for making yarns, and fabrics, garments, molded articles or other articles such as carpets from these yarns. Processes for incorporating optical brighteners into polyamide compositions, polymers and yarns to make fabrics and molded articles that exhibit superior whiteness after heat-setting are also disclosed. L'invention concerne une composition polyamide, comprenant un azurant optique en association avec un agent antimicrobien ou un stabilisateur antioxydant, ou les deux, ladite composition étant destinée à fabriquer des fils, des tissus, des vêtements, des articles moulés ou tout autre article tels que des tapis fabriqués à partir desdits fils. L'invention concerne des procédés permettant d'incorporer des azurants optiques à des compositions polyamides, des polymères et des fils, ce qui permet de fabriquer des tissus et des articles moulés qui présentent une blancheur supérieure après le chauffage.
