“…Wet and dry treatments of textiles might lead to stiffness or reactivity changes [42,43]. Kramar et al measured the electrical resistance of cotton and viscose fabrics impregnated with Ag + , Zn 2+ , and Cu 2+ ions at different relative humidity conditions [44], apart from the change in resistance due to the ion treatment the resistance also decreased with increasing humidity. Shim et al used carbon nanotubes coated cotton threads for humidity sensing and for mechanical/chemical durability tests [45].…”

Flexible Textile Strain Sensor Based on Copper-Coated Lyocell Type Cellulose Fabric

et al. 2019

Integration of sensors in textile garments requires the development of flexible conductive structures. In this work, cellulose-based woven lyocell fabrics were coated with copper during an electroless step, produced at 0.0284 M copper sulfate pentahydrate, 0.079 M potassium hydrogen L-tartrate, and 0.94 M formaldehyde concentrations. High concentrations led to high homogeneous copper reaction rates and the heterogeneous copper deposition process was diffusion controlled. Thus, the rate of copper deposition did not increase on the cellulose surface. Conductivity of copper coatings was investigated by the resistance with a four probe technique during fabric deformation. In cyclic tensile tests, the resistance of coated fabric (19 × 1.5 cm2) decreased from 13.2–3.7 Ω at 2.2% elongation. In flex tests, the resistance increased from 5.2–6.6 Ω after 5000 bending cycles. After repeated wetting and drying cycles, the resistance increased by 2.6 × 105. The resistance raised from 11–23 Ω/square with increasing relative humidity from 20–80%, which is likely due to hygroscopic expansion of fibers. This work improves the understanding of conductive copper coating on textiles and shows their applicability in flexible strain sensors.

“…Od elektrofi zičkih svojstava, u koja spadaju električna otpornost, relativna dielektrična propustljivost, tangens dielektričnih gubitaka i specifi čna električna provodljivost, najčešće je određivana električna otpornost tekstilnih materijala, zbog poznate činjenice da su intenzitet i brzina rasipanja generisanog statičkog naelektrisanja sa tekstilnog materijala obrnuto srazmerni njegovoj električnoj otpornost [1][2][3][4][5][12][13][14][15][16][17][18]. Određivanju električne otpornosti tekstilnih materijala posvećen je veliki broj radova [2-5, 12-17, 19-21].…”

“…Registrovano je da tkanine keper prepletaja imaju nižu otpornost od tkanina platno prepletaja [17,19], ali i da kod tkanina koje su dobijene od mešavine vlakana različite električne otpornosti dominantnu ulogu u provođenju električne struje ima komponenta sa manjom otpornošću [2,15]. Konstatovano je da obrada celuloznih tkanina dielektričnim barijernim pražnjenjem u vazduhu pri atmosferskom pritisku dovodi do sniženja njihovih električnih otpornosti, pri čemu se dodatno sniženje otpornosti tkanina postiže inkorporiranjem jona metala (srebro, bakar i cink) [12]. Takođe, registrovana je izrazita zavisnost električne otpornosti tkanina, ali i ostalih tekstilnih materijala, od vlažnosti ispitivane sredine i sadržaja vlage u uzorcima, čiji porast dovodi do sniženja električne otpornosti materijala [1-3, 12, 14-18, 20-22].…”

“…Zapreminska električna otpornost međupostave i ispitivanih odevnih tkanina, pre i posle termičkog fi ksiranja tkane međupostave, određena je primenom uređaja koji je razvijen na Katedri za tekstilno inženjerstvo Tehnološko-metalurškog fakulteta Univerziteta u Beogradu. Za određivanje električne otpornosti tkani-na korišćena je stacionarna naponska metoda, čiji je način funkcionisanja opisan u većem broju radova [2,5,12,13,16]. Zapreminske električne otpornosti tkanina određene su u oba njena strukturna pravca, tj.…”

Apstrakt: U radu su ispitivani parametri komfora odevnih tkanina pre i posle termičkog fi ksiranja međupostave. Kao eksperimentalni materijal korišćene su dve tkanine dobijene od mešavine pamučnih i poliestarskih vlakana izrađene u keper 3/1S prepletaju, kao i pamučna tkana međupostava sa tačkasto nanetim termoplastičnim vezivnim sredstvom. Od parametara komfora određivani su propustljivost vazduha i specifi čna zapreminska električna otpornost. Dobijeni rezultati su pokazali da je propustljivost vazduha u funkciji poroznosti ispitivanih uzoraka, njihove debljine i termičkog fi ksiranja međupostave, dok je specifi čna zapreminska električna otpornost u funkciji strukturnih karakteristika tkanina, termičkog fi ksiranja međupostave i relativne vlažnosti vazduha. Registrovano je da termičko fi ksiranje međupostave dovodi do smanjenja propustljivosti vazduha i porasta vrednosti specifi čne zapreminske električne otpornosti ispitivanih tkanina. Ključne reči: odevne tkanine, tkana međupostava sa termoplastičnim vezivnim sredstvom, propustljivost vazduha, specifi čna zapreminska električna otpornost Abstract: In this paper, comfort parameters of clothing woven fabrics, before and after thermal fi xation of interlining, were investigated. Two woven fabrics obtained from cotton and polyester fi ber blends made in twill 3/1S weave, as well as cotton fusible woven dot fuse coat interlining, were used as experimental material. Air permeability and dc volume electrical resistivity were investigated as comfort parameters. The obtained results showed that the air permeability is in a function of porosity of the tested samples, their thickness and thermal fi xation of interlining, while the dc volume electrical resistivity is in a function of the structural characteristics of woven fabrics, thermal fi xation of interlining as well as relative air humidity. It is observed that the thermal fi xation of interlining leads to a reduction in air permeability and an increase in the value of dc volume electrical resistivity of the tested woven fabrics.
