Bio-innovation in Cotton Fabric Scouring - Acid and Neutral Pectinases

Using biotechnology during textile processing has been known for years due to its environmental benefits and special performance of enzymes in comparison with the conventional processing of textiles. This paper deals with the bioscouring of cotton fabric with acid and neutral pectinases in comparison with alkali scouring. Variations in technological procedures, as expressed through pad-roll and exhaustion, were also identified for the bioscouring of cotton fabrics. The varied impacts of alkali, acid, and neutral pectinases on the properties of cotton fabrics throughout the processing technology were evaluated for electrokinetic phenomena, hydrophilicity, mechanical and chemical degradation, inorganic residues, and whiteness

Dizajn luminiscentnim efektima na platnu od lana i kudjelje

Rad je inspiriran umjetničkom ideologijom i načinom rada i djela umjetnika Bauhausa. Kako bi se realizirala početna ideja, idejni radovi napravljeni u tehnici kolaža poslužili su kao svojevrsna maketa za sjenilo za rasvjetno tijelo. Tehnološkim postupcima i metodama izrađeni su efekti na tekstilnom materijalu, platnu od lana i kudjelje, tkanom na starinskom tkalačkom stanu prije stotinjak godina. Budući da se platno sastoji od dva različita stabljična vlakna, njihovim bijeljenjem postižu se različite nijanse bijele, što pridonosi efektnijem izgleda tkanine. Obrađeno platno fi ksirano je na metalne nosače ormarića, te tako kao cjelina stvaraju ormarić s tekstilnim sjenilom za rasvjetno tijelo koja se može primijeniti u bilo kojem interijeru

THE FABRIC HAND OF ANTIMICROBIAL PROTECTED COTTON FABRICS USING ANTIBIOTICS AND ANTISEPTICS

Healthy and active lifestyle has led in recent years to the rapid development of antimicrobial treatment. Such antimicrobial materials provide lasting freshness and a sense of security and well-being of consumers. At first glance it seems easy to achieve antimicrobial properties, but the persistence of such treatment is a bigger problem. Application of natural zeolite nanoparticles for antimicrobial protection has shown increased activity and synergism with some antimicrobial agents, e.g. azalide. On the other hand, azalides are not acceptable from dermatological or ethics view, because of resistance development. This paper deals with the selection of optimal antimicrobial treatment which will provide protection against Gram positive (Staphylococcus aureus) and Gram negative (Klebsiella pneumoniae) bacteria, as well as fungi (Candida albicans). For this purpose, 100 % raw and bleached cotton knitted fabric was treated by exhaustion with natural zeolite nanoparticles and different antimicrobial agents cationic surfactant, azalide and antiseptic. It is well known that the cationic surfactants significantly improve fabric hand, but the high concentrations of activated zeolite getting it worse. Therefore, the influence of these treatments on fabric hand (subjective and objective evaluated) was investigated

Postupci proizvodnje, uzorkovanja i analize deterdženata

U radu su opisani postupci proizvodnje deterdženata u praškastom, kapljevitom, gel i krutom obliku. Istaknuta je važnost uzorkovanja deterdženta u analizi te su izdvojene metode analize tvari prema hrvatskim i svjetskim normama. Opisani su uvjeti stavljanja deterdženata na tržište, opći uvjeti proizvodnje, te prava, dužnosti i ovlasti nadležnih tijela u vezi s deterdžentima kroz nacionalni dokument Pravilnik o deterdžentima, koji je usklađen s Europskom komisijom
