Abstract

Způsob výroby netkané textilie, zahrnující kroky A) samostatné roztavení i. první složky obsahující nosnou polyesterovou kompozici, která obsahuje polyethylentereftalát, a ii. druhé složky obsahující - pojící polyesterovou kompozici s bodem tání nižším než nosná polyesterová kompozice a - alespoň jednu doplňkovou polyesterovou kompozici, která obsahuje recyklovaný polyethylentereftalát, přičemž pojící polyesterová kompozice obsahuje kopolymer polyethylentereftalátu, a B) přivedení roztavených polymerních materiálů ke kapilárám zvlákňovací hlavy a vytlačování roztavených polymerních materiálů skrz kapiláry, C) vytváření multikomponentních nekonečných filamentů z roztavených polymerních materiálů vystupujících z kapilár, i. přičemž druhá složka prochází v podélném směru filamentů a tvoří alespoň část povrchu filamentů, a D) chlazení vytvořených filamentů tekoucím médiem s teplotou v rozmezí 10 až 90 °C a dloužení vláken s dloužícím koeficientem v rozmezí 200 až 1300 pro dosažení semistabilního krystalického stavu alespoň druhé složky, a E) náhodné pokládání filamentů na formovací pás pro vytvoření rouna, a F) tepelné pojení rouna.
