Повний текст джерелаTiO2 and Ag nanoparticle multilayered films were constructed on model substrates and textiles via Layer-by-Layer (LbL) assembly. The TiO2 nanoparticle based films constructed on model substrates showed a non-conventional photocatalytic behaviour for gas phase formic acid mineralisation upon UV-A irradiation, and a high mineralisation was obtained for a single layer TiO2 nanoparticle film. These films also showed biocidal properties upon UV-A irradiation. The elaboration of a one-pot method, combining the photo-induced synthesis of Ag nanoparticles and the LbL deposition of TiO2 nanoparticle layer, allowed the direct synthesis of Ag nanoparticles within the films and a high enhancement of the film photocatalytic properties. The construction methods were successfully transfered on textile surfaces. The films were photocatalytically active and biocidal under UV-A irradiation after several washing treatment cycles

Повний текст джерелаIt has been chosen to study valorization of low-cost industrial lignin as additive in designing the flame retardant (FR) system for polyamide 11 (PA) to develop biobased textile structure. The main focus of this thesis work is to consider lignin as carbon source and introduce in a textile structure in combination with phosphinate salt (FR agent). In the primary study, chemically different industrial lignins were incorporated in PA by extrusion to investigate the charring and fire retardant behaviour of the prepared binary blends. In addition, the introduction of sulphonated lignins significantly reduced the peak of the heat release rate (PHRR) and of the total heat release (THR), and a noticeable increase of the char residue was observed after forced combustion test. In the next approach, lignin was exploited as carbon source in combination with commercially available phosphinate FR (i.e., ZnP and AlP). To achieve this objective, a preliminary study carried out with laboratory grade lignin (LS) combined with ZnP to investigate the thermal stability and fire performance as well as the possible synergy between lignin and ZnP and with the polymer matrix. The results obtained in this study permitted to continue further, the practical implementation of lignin and multifilament production. In the next step, flame retarded blends were developed with direct addition of low-cost industrial lignins (LL and DL) with phosphinate FR. For the systematic understanding, various FR formulations were developed by varying the lignin and FR loading and characterized. Thermal decomposition analysis showed that the presence of lignin decreases the initial decomposition temperature (T5%) due to the decomposition of lignin which starts at a lower temperature region with the evolution of less thermally stable compounds and the maximum decomposition temperature (Tmax) shifts to higher temperature region, at this stage the formation of phenolic, carbonyls, hydrocarbons and CO2 along with phosphinate compounds occurs. Meanwhile, in the condensed phase thermally stable aromatic charred layer is formed because of lignin decomposition and phosphate compounds formation due to the presence of phosphinate metal salt. A higher amount of char residue is obtained when LL combined with ZnP/AlP as compared to the DL and ZnP/AlP blends. It is assumed that, during decomposition of LL, the sulfonate compounds release SO2 and transformed into thermally stable Na2SO4, hence giving rise to the stable char residue. The fire properties were assessed by cone calorimeter tests revealed the combination of lignin and phosphinate FR significantly reduced the PHRR and other fire-related parameters due to the formation of a protective char layer. The presence of lignin not only improve fire retardancy but also reduced the evolution of carbon monoxide (CO). More enhanced fire retardant properties were obtained with LL and ZnP/AlP combination reaches to 10 wt% in ternary blends, which not only promotes char formation but also confer the stability to char in the condensed phase. Furthermore, the most enhanced forced combustion results were obtained with LL and AlP (in particular, PA80-LL10-AlP10). Multifilament yarns were successfully produced for PA-DL-ZnP and PA-LL-ZnP combinations. However, the blends of AlP with lignin were not spinnable because of low compatibility and dispersion level of AlP in the polymer. Optical microscopy and tensile tests were performed to study the physical properties of multifilaments. A double layer (interlock structure) knitted fabrics were developed to evaluate fire behaviour analysis on fabric samples

Повний текст джерелаLe secteur de la teinture et de l’ennoblissement textile est de plus en plus conscient de son impact sur l’environnement dû principalement à la consommation élevée de l’eau et à sa pollution, et aux pertes d’énergie. Pour réduire ces impacts, les chercheurs proposent l’utilisation de molécules issues de ressources naturelles, pour traiter les textiles en limitant les impacts sur l’environnement. C’est le cas pour l’obtention de textiles colorés ou pour l’attribution de toute autre fonctionnalité. Cependant, il n’est pas évident que ces molécules bio-sourcées n’aient aucun impact sur l’environnement. On comprend l’importance d’évaluer les impacts de leur utilisation et d’améliorer leur profil environnemental. Or ce type d’étude est peu présent dans la littérature. La recherche présentée dans cette thèse comporte l’évaluation des impacts environnementaux en utilisant l’outil d’analyse du cycle de vie (ACV) pour la conception du traitement d’un tissu de polyester (PET) multifonctionnel avec des anthraquinones naturelles. La méthodologie d’éco conception que nous avons appliquée ouvre la voie à une bio-fonctionnalisation des textiles plus respectueuse de l’environnement. Les anthraquinones ont été obtenues par extraction des racines de plantes de garance et constituent le colorant appelé garance. Les trois questions principales abordées lors de ce travail de recherche sont formulées autour de l’utilisation de la garance : (I) Peut-on traiter les tissus de PET avec de la garance pour obtenir des propriétés multifonctionnelles ? (II) Quel est le profil environnemental du procédé de teinture du PET par la garance et comment l’améliorer ? (III) Quels sont les principaux challenges pour l’utilisation de l’ACV dans l’évaluation environnementale du traitement des textiles par des colorants naturels? Nous avons montré que la garance peut être utilisée pour conférer des propriétés multifonctionnelles au PET. Ensuite, nous avons pu orienter notre étude pour améliorer la durabilité des traitements par les procédés de fonctionnalisation à la fois par épuisement ou par foulardage. En s’appuyant sur l’ACV, l’optimisation de la teinture que nous avons réalisée réduit tous les impacts sur l’environnement. Cette étude nous permet d’identifier les challenges qui doivent être surmontés pour que l’ACV puisse contribuer à l’utilisation de bio-molécules pour la teinture des textiles dans le respect des principes de développement durable. Ils concernent le manque de données pour ces travaux de recherche et leur nature interdisciplinaire. Ainsi, en résolvant ces questions, on peut envisager aboutir à une bio- fonctionnalisation des textiles respectueuse de l’environnement.
Den höga miljöpåverkan från textilfärgning och efterbehandling, på grund av hög vattenförbrukning, dess förorening, och ineffektiv användning av energi, är idag välkänt. För att minska miljöpåverkan föreslår forskningsvärlden användning av färgämnen från naturliga resurser. Syftet med att använda dessa är att ge nya attribut till textilier utan att göra avkall på miljömässig hållbarhet. Attribut som ges kan vara färg och/eller andra egenskaper. En nackdel är dock att användningen av bio-baserade färgämnen är inte fri från att belasta miljön. Det blir därför av största betydelse att bedöma denna miljöpåverkan och förbättra miljöprofilen. Sådana studier är dock i allmänhet sällsynta. Studien som presenteras i denna avhandling har inkluderat miljöpåverkans- bedömning, med hjälp av livscykelanalys (LCA), i designprocessen av en multifunktionell polyester (PET) väv via naturliga antrakinoner. Genom att göra så har ett eko-design tillvägagångssätt använts, med avsikt att bana väg för miljömässigt hållbar bio-funktionalisering av textil. Antrakinonerna erhölls från rot extrakt av växten krapp (Rubia tinctorum L.), och hänvisas till som krapp färgämne. Frågeställningar var därför formulerade relaterat till användningen av krapp färgämne. Tre forskningsfrågor har besvarats: (I) Kan krapp färgämne verka multifunktionellt på en PET väv? (II) Hur ser miljöprofilen ut, från färgningsprocessen av PET med krapp färgämne, och hur kan den förbättras? (III) Vilka är de största utmaningarna med att använda LCA för att bedöma miljökonsekvenserna av textilfärgning med växtbaserade färgämnen? Det kan konkluderas att det finns potential för krapp färgämne att verka multifunktionellt på PET. Baserat på uppmuntrande resultat är en rekommendation för det framtida arbetet att fokusera på kvalitén hos de attribut som presenterats och deras förbättringspotential, både i färgning via färgbad och via foulard. LCA driven processoptimering av textilfärgningen förbättrade i varje miljöpåverkans- kategori som studerats. Emellertid har flera utmaningar identifierats som måste övervinnas för att LCA skall kunna bidra till en hållbar användning av multifunktionella växtbaserade färgämnen för textil. De största utmaningarna är bristen på tillgängliga data i forskningsstadiet och den tvärvetenskapliga forskningsarenan. Det är tänkt att om dessa utmaningar bemästras kan LCA bidra till en hållbar bio-funktionalisering av textil.

To date, the development of smart textiles, artificial skins, environmental sensory devices, and flexible/stretchable optoelectronics involve the innovation of material synthesis, mechanical design, and fabrication strategies have attracted considerable attention in wearable displays. The mechanically flexible and stretchable functions with cost-effective, facile, lightweight, and large-area expandability are essential modules to fabricate the optoelectronic devices in various wearable display applications. Among them, electrospinning is an easy, versatile, and inexpensive technique enables flexible morphology tuning, assembling various functional nanofibers, and high-throughput continuous production has motivated extensive studies on wearable electronics applications. Therefore, it is necessary to develop innovative projects including the environment-sensing elements with pH-sensing dependency, temperature-sensitive, full-color switchable chemosensors, stretchable electronics, and tactile sensors for various wearable electronics applications. The present PhD thesis can be categorized by four parts as below: 1. RGB-Switchable Porous Electrospun Nanofiber Chemoprobe-filter Prepared from Multifunctional Copolymers for Versatile Sensing of pH and Heavy Metals (Chapter 1): Novel red–green–blue (RGB) switchable probes based on fluorescent porous electrospun (ES) nanofibers exhibiting high sensitivity to pH and mercury ions (Hg2+) were prepared with poly(MMA-co-BNPTU-co-RhBAM)) by using a single-capillary spinneret. The MMA, BNPTU, and RhBAM moieties were designed to (i) permit formation of porous fibers, (ii) fluoresce for Hg2+ detection, and (iii) fluoresce for pH, respectively. The fluorescence emission of BNPTU (fluorescence resonance energy transfer (FRET) donor) changed from green to blue as it detected Hg2+. The fluorescence emission of RhBAM (FRET acceptor) was highly selective for pH, changing from nonfluorescent (pH 7) to exhibiting strong red fluorescence (pH 2). The full-color emission of the ES nanofibers included green, red, blue, purple, and white depending on the particular pH and Hg2+-concentration combination of the solution. The porous ES nanofibers with 30-nm pores were fabricated using hydrophobic MMA, low-boiling-point solvent, and at a high relative humidity (80%). These porous ES nanofibers had a higher surface-to-volume ratio than did the corresponding thin films, which enhanced their performance. 2. Novel Magnet and Thermoresponsive Chemosensory Electrospinning Fluorescent Nanofibers and Their Sensing Capability for Metal Ions (Chapter 2): Novel multifunctional switchable chemosensors based on fluorescent electrospun (ES) nanofibers with sensitivity toward magnetism, temperature, and mercury ions (Hg2+) were prepared using blends of poly(NIPAAm-co-NMA-co-AA), the fluorescent probe (BNPTU), and magnetite nanoparticles (NPs), and a single-capillary spinneret. The moieties of N-isopropylacrylamide, N-methylolacrylamide, acrylic acid, BNPTU, and Iron oxide (Fe3O4) NPs were designed to provide thermoresponsiveness, chemical cross-linking, Fe3O4 NPs dispersion, Hg2+ sensing, and magnetism, respectively. The prepared nanofibers exhibited ultrasensitivity to Hg2+ (as low as 10−3 M) because of an 80-nm blueshift of the emission maximum (from green to blue) and 1.6-fold enhancement of the emission intensity, as well as substantial volume (or hydrophilic to hydrophobic) changes between 30 and 60 °C, attributed to the low critical solution temperature of the thermoresponsive N-isopropylacrylamide moiety. Such temperature-dependent variations in the presence of Hg2+ engendered distinct on–off switching of photoluminescence. The magnetic ES nanofibers can be collected using a magnet rather than being extracted through alternative methods. 3. Mechanically Robust Silver Nanowire–Polydimethylsiloxane Electrode Based on Facile Transfer Printing Techniques for Wearable Displays (Chapter 3): Silver nanowire (AgNW) networks have attracted considerable attention as transparent electrodes for emerging flexible optoelectronics. However, transference of such networks onto diverse arbitrary substrates with high conductivity remains a challenge because of the possibility of detaching and sliding occurring at the interface. Therefore, we developed a water-assisted transfer printing method for fabrication and transfer of an AgNW–polydimethylsiloxane (PDMS) electrode. The innovative approach exhibits a robust ability for thin film transfer onto arbitrary substrates and has highly controlled and nondestructive characteristics. The obtained electrodes exhibited high conductivity (9 Ω/sq, 82% at 550 nm, σDC/σOp ≈ 200), tensile strain (0% to 50%), and flexibility (bending radius of less than 2 mm) without significant loss of conductivity compared with devices fabricated through conventional methods. Furthermore, we demonstrated novel textile-based flexible light-emitting electrochemical cell (PLECs) based on the stretchable AgNW-PDMS electrode and buckling concept, thereby realizing highly stretchable PLECs with excellent performance and mechanical robustness. The strained device luminance intensity was optimized to 58 cd m-2 at 7 V under 10% linear strain without damaging the electroluminescent properties. Notably, this effective and practical transfer method provides an approach for developing electronic nanowire devices with unique configurations and high performance. 4. Mechanically Robust and Ultra-Sensitive Skin-Inspired Nanofiber-based Resistive Pressure Sensor Based on Fibrous Interlocked Microstructures (Chapter 4): To date, most of the skin-like pressure sensors largely depend on traditional lithography technique to fabricate the microstructures, limiting their wide practical applications due to the high-cost process and the redundant fabrication procedure. Herein, we present a cost-effective, lithographic-free, and large-area expandability to fabricate skin-inspired resistant-type pressure sensors with ultra-performance and lightweight based on fibrous interlocked-microstructures (FIM). The unique sandwich-structured conducting nanofiber (ESSCN) configuration is composed of poly(styrene-block-ethylene-ran-butylene-block-styrene) (SEBS) natural rubber and silver nanoparticles (AgNPs), whereas the dielectric SEBS nanofiber is employed as the middle layer, sandwiched by two SEBS/AgNPs electrodes at top and bottom for packaging. The FIM endows the obtained pressure sensors show superior performance, including ultra-high sensitivity of 71.07 kPa-1 in a low-pressure regime (<0.06 kPa), rapid response time (<2 ms), highly reproducible stability (>100 cycles), mechanical stimuli sensing (pressure, strain, and curvature). As a proof-of-concept demonstration, the sensors have been used for integration with RGB-LED wristband and garments, monitoring human physiological signals, and detect spatial pressure distribution, thereby endowing our ESSCN has broader potential applications in versatile electronic skin and human machine interfaces. In summary, based on electrospinning, spraying coating, transfer printing technology, we successful prepared the ultra-sensitivity and full-color switchable functions smart textiles (part one), multifunctional magnetic and fluorescence chemosensor (part two), facile, inexpensive, and chemical free transfer printing technology (part three), skin-inspired resistive pressure sensors (part four). The present study demonstrated that full-color switchable and pH-sensing dependency chemosensors, temperature-sensitive and magnetic chemosensors, chemical free transfer printing technology, skin-inspired resistive pressure sensors have potential for diverse applications, such as water purification, sensing filters, environment-sensing devices, multifunctional smart textiles, wearable electronics, tactile sensors, and artificial skins.

Despite how important 3C products are in people's daily life, wearing cloths and shoes is still more essential than having an iPhone. No individual can live without apparel and footwear, and Taiwanese textile manufacturers continue to lead the market and contribute greatly to Taiwan's economy. Comparing to IT industry that had a high growth rate and public awareness, textile industry seems to be declining and struggling. However, this so-called sunset industry, which was not encouraged by government policy or its people, did not fall into the darkness. Instead, textile that made in Taiwan brings performance and lifestyle into premium athletic world and captured over 50% of the sportswear market. Junmay started the business with woven labels, a tiny piece of jacquard fabric that nevertheless is on almost every products in one’s daily life such as clothes, accessories and shoes and shows the most critical information of the product- its brand. After 35 years of specializing in jacquard woven technology, Junmay expanded its capabilities from a small woven labels to multi-purpose jacquard woven textile. Furthermore, Junmay has been investing heavily in R&D and finest machineries, becoming the first mover of one-piece engineered upper that greatly simplified the manufacturing process for footwear. Combining R&D with worldwide production facilities, Junmay is now a long-term partner with many premium brands and collaborates closely with their developers and designers for most innovative materials and technology, such as 3D weaving, high-abrasion jacquard, and functional textile like antibacterial and water repellent. By providing customized solutions to brands, Junmay pursuits for value-added and sustainable products to customers, suppliers, as well as to the society.
