Połączenie procesów prania wstępnego i bielenia mieszanek bawełny i lnu z zastosowaniem prawie neutralnego układu nadtlenkowego
Języki publikacji
Abstrakty
The simultaneous scouring and bleaching of cotton/linen blends was performed in a nearneutral activated peroxide system (pH = 7.2). A response surface quadratic model (RSQM) based on the central composite design (CCD) was established to investigate and optimise the bleaching performance. Research results showed that hydrophobic impurities in the blends had little impact on the bleaching. Temperature was the most significant factor affecting the fabric’s whiteness index (WI), followed by the concentration and duration of the activator tetraacetylethylenediamine (TAED). The optimised process was performed at 70°C for 40 min, incorporating 20 mmol/l of TAED and 42 mmol/l of H2O2. Compared with the conventional process carried out at 95 °C for 60 min and adding 80 mmol/l H2O2, the activation process provided the fabric with comparable WI and wettability, a smoother and cleaner microcosmic surface, as well as the advantages of saving energy and preserving fabric. This study confirmed the feasibility of an efficient one-step process for neutral scouring and bleaching.
Równoczesne pranie i bielenie mieszanek bawełny i lnu przeprowadzono w prawie neutralnym układzie nadtlenkowym (pH = 7,2). W celu zbadania i zoptymalizowania wydajności wybielania został utworzony model kwadratowy powierzchni odpowiedzi (RSQM) oparty na centralnej konstrukcji kompozytowej (CCD). Wyniki badań wykazały, że zanieczyszczenia hydrofobowe w mieszankach miały niewielki wpływ na bielenie. Temperatura była najważniejszym czynnikiem wpływającym na wskaźnik bieli tkaniny (WI), a następnie stężenie i czas trwania aktywatora tetraacetyloetylenodiaminy (TAED). Zoptymalizowany proces prowadzono w temperaturze 70 °C przez 40 min., stosując 20 mmol/litr TAED i 42 mmol/litr H2O2. W porównaniu z konwencjonalnym procesem prowadzonym w 95 °C przez 60 min. i dodawaniu 80 mmol/litr H2O2, proces aktywacji zapewnił tkaninie porównywalny wskaźnik WI i zwilżalność oraz gładszą i czystszą powierzchnię, a także korzyści wynikające z oszczędności energii. Przeprowadzone badanie potwierdziło mozliwość wykonania wydajnego jednoetapowego procesu prania wstępnego i bielenia.
