Textile air management systems are used in modern buildings to improve overall indoor air quality. During use and storage, industrial textiles are negatively affected by microbes. Adding biocide to synthetic fibres can control the detrimental effects of antimicrobial finishing on textiles. Antimicrobial textiles have seen a rapid increase in demand due to consumers’ concern over hygiene and active lifestyles as well as with the aim to improve overall functionality. An antimicrobial treatment with a long lifespan, that is, resistant to washing, is presented in this paper. A new commercial antimicrobial product named Si Bac-Pure was used in woven polyester fabrics to treat them against bacteria. The antimicrobial activity was measured after twenty washing and drying cycles. Good antimicrobial and antifungal activity is produced in treated fabrics after treatment with the stated finishing agents. The antimicrobial treatment has significant antistatic properties that are important for industrial air management systems.
In this study, a simple, general and straightforward method for growing metal-organic frameworks (MOFs) crystals directly on nanofibers is presented. A chelating polymer was first blent with metal cation and then electrospun. The obtained nanofibers were immersed in a linker solution. Metal cations were released and the metal-organic frameworks crystals were grown on the fibers’ surface. In this work, this method was tested with polyvinyl alcohol as chelating polymer, Zn2+ as metal cation and Terephthalic acid as linker. The pair cation/linker corresponds to the MOF-5. The latter is a robust metal organic framework formed from Zn4O nodes with 1,4-benzodicarboxylic acid struts between the nodes. SEM images revealed that the MOF-5 nanocrystals have grown along the PVA/Zn2+ nanofibers that served as the crystals’ growth template by providing the Zn2+ ions. This result was also confirmed by infrared spectroscopy, which indicates the presence of characteristic bands of MOF-5 in the modified nanofibers spectrum. Moreover, the X-ray diffraction showed that MOF-5 material was well crystallized on the nanofibers surface according to a cubic symmetry with a space group Fm-3m and a lattice constant a = 25.8849 Å.
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”.
