Incorporation of cyclodextrins (CDs) into electrospun nanofibrous materials can be considered as potential candidates for functional medical textile applications. Naproxen (NAP) is a type of non-steroidal anti-inflammatory drug commonly administered for the treatment of pain, inflammation and fever. Drug-inclusion complex formation with CDs is an approach to improve the aqueous solubility via molecular encapsulation of the drug within the cavity of the more soluble CD molecule. In this study, NAP or different NAP-CD inclusion complexes loaded nanofibres were successfully produced through electrospinning and characterised. The inclusion complex loaded mats exhibited significantly faster release profiles than NAP-loaded thermoplastic polyurethane (TPU) mats. Overall, NAP-inclusion complex loaded TPU electrospun nanofibres could be used as drug delivery systems for acute pain treatments since they possess a highly porous structure that can release the drug immediately.

Automatic Indigo Measurement System as Part of a Dosing System for Indigo Dyeing

Indigo dye has been widely used for dyeing traditional blue denim products intended to give a worn faded look. However, while using the warp yarn dyeing process with indigo dye often occur problems of colour variation. To prevent colour variation, controlling the indigo dye baths is an important factor. The objectives of this study include adjusting dosages of leuco indigo, hydrosulphite, pH (caustic), using an automatic measurement and dosing system taking redox titrations as the basis. It was observed that measurements carried out with this system became more reliable and also had a positive effect on the quality of the product.

Barwnik indygo jest szeroko stosowany dla barwienia tradycyjnych tkanin dżinsowych, którym nadaje się wygląd zużycia. Podczas barwnika nitek osnowy za pomocą indygo, często występują problemy z zachowaniem odpowiedniego odcienia. Dlatego też kontrola kąpieli barwiarskiej z barwnikami indygo jest ważnym zagadnieniem. Przedmiotem przedstawionej pracy jest między innymi dozowanie leuko-indygo, podsiarczynu oraz ługu sodowego (dla regulacji pH), za pomocą systemu automatycznego pomiaru i dozowania opartego na miareczkowaniu redox.
