Firstly, polymer solutions were prepared at various ZnO\u0000concentrations such as 0, 0.2, 0.4, 0.6, 0.8, 1. Then solution properties (conductivity, viscosity, surface\u0000tension) were determined and analysed the effects of ZnO concentration on the solution properties. PU/ZnO\u0000nanofibers produced via electrospinning under the optimum process parameters (voltage, distance between\u0000electrodes, feed rate and atmospheric conditions). Finally, the nanofibers were characterized in terms of\u0000fibre morphology, thermal stability, permeability and antibacterial activity using SEM-EDS, DSC-TGA,\u0000water vapour permeability and disk diffusion methods. According to the solution results; it was observed\u0000that conductivity and surface tension decrease significantly with ZnO addition. On the other hand, solution\u0000viscosity increases as the ZnO concentration increases. From the SEM images, it has been seen clearly that\u0000average fibre diameter increases with ZnO concentration and incorporation of ZnO particles to the fibre\u0000structure was verified by SEM-EDS. According to the thermal analyse result, nanofibers begin to degrade\u0000between 271.94 ºC and 298.73 ºC. In addition, water vapour permeability increases as the ZnO\u0000concentration increase. Lastly antibacterial activity against gram negative (E.coli) and gram positive (S.\u0000aureus) was determined with specific zone diameter.","PeriodicalId":22214,"journal":{"name":"TEXTEH Proceedings","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74773546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study attempts to highlight the possibility of using cochineal natural dye in the printing of polyester fabrics after surface modification by O2/Ar plasma treatment. The colour strength, air permeability, crease recovery angle of printed fabrics, colour fastness to rubbing, washing and light, were also studied. The surfaces of untreated and plasma-treated polyester fabrics were analysed by SEM to compare the morphological changes. Surface roughness and cracks were indicated after the plasma pretreatment.\u0000The results indicated that plasma treatment could improve the printability of polyester fabric compared with untreated samples, with enhanced the adhesion and penetration of printing paste to the surface.\u0000The air permeability of printed fabrics has decreased, while the angle of crease recovery has increased.

The target group of textile creatives is considered\u0000to include both young professionals in the textile industry as well as students of Higher Education in technical\u0000fields. A partnership of six prestigious research and educational providers in Europe, coordinated by INCDTP –\u0000Bucharest have joined their expertise to offer educational modules related to this need, within the Erasmus+\u0000project “OptimTex- Software tools for textiles creatives”. The project has duration of two years (2020-2022) and\u0000has already implemented the educational modules in e-learning format on the project’s website\u0000(www.optimtex.eu). The five educational modules follow the main textile technologies and describe in a\u0000Problem-Based-Learning (PBL) approach software applications for: weaving, knitting, virtual prototyping of\u0000clothing, embroidery of e-textiles (electronic textiles) and experimental design. The PBL approach consists in\u0000learning by examples, followed by the theory, the corresponding software applications and a quiz for selfassessment.\u0000The e-learning instrument was programmed in HTML5 and JavaScript and offers quick access the\u0000educational modules. INCDTP has conceived the fifth module on experimental design, by tackling plasma\u0000treatments of textiles for various functionalities: hydrophobic, hydrophilic and electrical conductivity. Full\u0000factorial, Central Composite Design and Fractional factorial experimental design plans were described. This\u0000topic is of interest for the envisaged target group, for it represents alternative and useful knowledge to the\u0000official curricula of Higher Education engineering studies.

Therefore, the goal is to create textile materials capable to act against bacteria, virus or fungi, with a long-lasting performance but, at the same time, that could be comfortable and safe for their users. In this sense, based on the advantages of nanotechnology, the aim of this work was to functionalize organic raw cotton fibers with zinc nanoparticles\u0000(NPs) and previously tretated with NaOH, for the further production of multifunctional yarns with antimicrobial activity. Thereby, the fibers functionalization was tested using 1% w/w and 2% w/w of zinc NPs aqueous dispersion, being subsequently evaluated their distribution, chemical nature and zinc concentration by SEM/EDS and Atomic Absorption Spectroscopy, respectively. Subsequently, using the functionalized fibers, a yarn was spinned and their structural, mechanical and moisture management properties determined. Also, to assess the influence of the produced yarn on the properties of a fibrous structure, a single jersey knit sample was further produced and evaluated regarding their mechanical, moisture management and antibacterial properties. Based on the methodology used it was possible to develop a yarn with a tenacity 24% higher and a knit sample 28% more breathable and with a water evaporating ratio 37% higher than the one without any\u0000treatment or functionalization, but mainly with a strong antibacterial activity against both gram-negative (Klebsiella Pneumoniae) and gram-positive (Staphylococcus Aureus) bacteria, presenting therefore potential to be used in the production of effective PPEs.","PeriodicalId":22214,"journal":{"name":"TEXTEH Proceedings","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82391878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such optimal conditions include a humid environment\u0000around the wound bed, efficient oxygen circulation to help regenerate cells and tissues, and low bacterial\u0000contamination. Composite matrices have several layers and can be used as primary or secondary dressings.\u0000Most composite dressings have three layers, respectively a semi-adherent or non-adherent layer, an absorbent\u0000layer, and a bacterial barrier layer. A method to obtaining these materials, which can be assimilated to layerby-\u0000layer deposition, or which can be operated in this regime, is represented by electrospinning. However, the\u0000deposition technique by electrospinning on textile surfaces (fabrics or nonwovens) raises some problems\u0000related to the electrostatic behaviour of textile fibres with dielectric properties.
