Abstract:Cilj magistrske naloge, je ugotoviti vpliv predobdelave poliamidnega materiala iz tekstilnega odpada na učinkovitost njegove razgradnje. Razgradnja je potekala z nevtralno hidrolizo, pri čemer smo želeli v rezultatu čim večjo prisotnost monomera ε – kaprolaktam. Uporabili smo vzorce, ki so bili obarvani v svetlih in temnih tonih ter surovi ne-obarvan odpad poliamidne preje. Obarvane vzorce smo pred razgradnjo razbarvali in nato ročno oprali z neionskim pralnim sredstvom (NPS). Surove vzorce smo oprali ročno in industrijsko, prav tako z NPS. Po končani razgradnji smo vzorec ločili na tekočo in trdno fazo ter izvedli analize s FTIR spektroskopijo in LC-MC kromatografijo, da smo videli katera vrsta predobdelave je bila najučinkovitejša pri pridobitvi čim več tekoče faze v rezultatu in čim višjega absolutnega deleža monomera. Najvišji delež monomera je bil pri vzorcu temno obarvane preje, ki smo jo dvakrat razbarvali in nato ročno oprali z NPS in pri surovem vzorcu, ročno opranem in razgrajenem na reaktorju, ki stabilno vzdržuje pogoje razgradnje.

Title:Influence of PA textile waste pre-treatment on its decomposition efficiency
Abstract:The aim of the master's thesis is to determine the influence of the pretreatment of polyamide material from textile waste on the effectiveness of its decomposition. Decomposition took place by neutral hydrolysis, and we wanted the result to have as much of the ε-caprolactam monomer as possible. We used samples that were dyed in light and dark tones and raw non-dyed polyamide yarn waste. Stained samples were decolourized before degradation and then washed by hand with a non-ionic detergent (NPS). Raw samples were washed manually and industrially, also with NPS. After the decomposition was completed, the sample was separated into liquid and solid phase and analysed with FTIR spectroscopy and LC-MC chromatography to see which type of pretreatment was the most effective in obtaining as much liquid phase as possible in the result and as high an absolute proportion of monomer as possible The highest proportion of monomer was found in the sample of dark colored yarn, which was dyed twice and then hand-washed with NPS, and in the raw sample, hand-washed and degraded in a reactor that stably maintains degradation conditions.
