Functional textiles are one of the most important fields in textile industry and textile materials science. They include breathable, heat and cold-resistant materials, ultra-strong fabrics (e.g. as reinforcement for composites), new flameretardant fabrics (e.g. intumescent materials), optimisation of textile fabrics for acoustic properties, etc. Functional textiles became more and more important materials for various applications and interest in them grew year by year; and more and more conferences are focused on functional textiles, as well as the events which are not only textile conferences but encompass various fields of Material Science. This paper presents a short overview about the European Materials Research Society 2014 Fall meeting conference Symposium M “Functional textiles - from research and development to innovations and industrial uptake” and the projects which participated as symposium co-organisers: the European Coordination Action 2BFUNTEX funded by the EC 7th Framework Programme NMP, the COST Action MP1105 on “Sustainable flame retardancy for textiles and related materials based on nanoparticles substituting conventional chemicals (FLARETEX)” and the COST Action MP1206 on “Electrospun Nano-fibres for bio inspired composite materials and innovative industrial applications”.

Electrospinning is remarkably a simple and versatile method for producing nanofibres. The diameter of nanofibres can vary from 10 nm to >1000 nm. In electrospinning, most of the attention is focused on producing fibres with a uniform diameter. It is very important to understand how the diameter and its distribution vary with the materials used and the processing parameters. An analysis of literature sources has shown that the distribution curves of the diameters obtained are very complex and do not resemble normal distributions, while they do more closely correspond to those of compound distributions. The goal of this article is to analyse the distributions of the nanofibre diameters and to propose a new method for the evaluation process of nanofibres and the quality of a nanofibre web. The uniformity of structure and the quality of nanofibres web must be described by average values. The peaks of modal values and the percentage quantity of them must be used for evaluation of a web structure.

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.
