Preparation and properties of phenolic compound/BTCA treated cotton fabrics for Functional Textile applications
Cellulose, 2015Co-Authors: Kyung Hwa HongAbstract:There is currently much interest in natural phenolic compounds as bioactive components of food. The roles of many fruits and vegetables in disease prevention have been attributed, in part, to the antibacterial and antioxidant properties of their constituent polyphenols. In this study, cotton fabrics were treated by phenolic compounds, pyrogallol, phloroglucinol, pyrocatechol, and resorcinol, to assess their antibacterial and antioxidant capabilities on clothing material. The treatment was conducted via a pad-dry-cure process and 1,2,3,4,-butanetetra carboxylic acid was used as a crosslinker in the finishing process to improve the treatment efficiency. After the finishing step, the phenolic compound treated cotton fabrics were investigated by FT-IR, color spectrophotometry, an antibacterial test, and an antioxidant test. Through the investigation, it was discovered pyrogallol is the most effective phenolic compound for cotton treatment, and the treated cotton fabric shows >99.9 % antibacterial ability and >90 % antioxidant ability.

Relation between the particle size and release characteristics of aromatic melamine microcapsules in Functional Textile applications
RSC Advances, 2019Co-Authors: Zhao Hongbin, Xuening Fei, Lingyun Cao, Baolian Zhang, Xin LiuAbstract:The relation between the particle size and release characteristics of aromatic microcapsules with a melamine resin shell in Functional Textile applications have been investigated. Firstly, the microcapsules are characterized based on their Fourier transform infrared spectra, encapsulation efficiencies, particle size distributions, optical images, and scanning electron microscopy images. The impregnation performances of the microcapsules have been initially evaluated using image analysis. Subsequently, the impregnation efficiency and broken release characteristics are semi-quantitatively analyzed using solid-phase microextraction-gas chromatography-mass spectrometry. The analysis results show that the highest impregnation efficiency and broken release intensity could be observed when the microcapsule size was similar to the fiber diameter (25–30 μm). Eventually, the sustained release of the microcapsules over a period of 2400 h was evaluated using the weighing calculation method, and the trends were studied using the Peppas model. It was found that the microcapsule release rate slowly and continuously decreased with time, and the release rates significantly increased with the decrease in microcapsule particle size. Thus, it could be concluded that the large microcapsules exhibited better leak tightness than the small microcapsules, whereas the small microcapsules exhibited faster sustained release rates.

Smart hydrogel-Functionalized Textile system with moisture management property for skin application
Smart Materials and Structures, 2014Co-Authors: Xiaowen Wang, Zongyue Yang, Yeeyee Kong, Huawen Hu, Bin Fei, Liang He, John H. XinAbstract:In this study, a Functional Textile-based material for topical skin application was fabricated by coating a thermoresponsive hydrogel onto one side of absorbent nonwoven fabric. The thermoresponsive hydrogel was synthesized easily through coupling of poly (ethylene glycol) (PEG) and poly (-caprolactone) (PCL) with hexamethylene diisocyanate (HMDI) as a chemical linker. The chemical structure of the as-prepared triblock copolymer hydrogel was unraveled by FTIR and 1H NMR analysis. The hydrogel showed a temperature-triggered sol-gel transition behavior and high potential for use as drug controlled release. When the surrounding temperature was close to the skin temperature of around 34 °C, it became a moisture management system where the liquids including sweat, blood, and other body fluids can be transported unidirectionally from one fabric side with the hydrophobic hydrogel coating to the untreated opposite side. This thereby showed that the thermoresponsive hydrogel-coated Textile materials had a function to keep topical skin area clean, breathable, and comfortable, thus suggesting a great potential and significance for long-term skin treatment application. The structure and surface morphology of the thermoresponsive hydrogel, in vitro drug release behavior, and the mechanism of unidirectional water transport were investigated in detail. Our success in preparation of the Functional Textile composites will pave the way for development of various polymer- or Textile-based Functional materials that are applicable in the real world.

multi Functional Textile design using in situ ag nps incorporation into natural fabric matrix
Dyes and Pigments, 2015Co-Authors: Mohamed Rehan, Hamada Mashaly, Salwa Mowafi, Abou A Elkheir, Hossam E EmamAbstract:Abstract The multiFunctional natural fabrics as colored, antibacterial and UV-protective fabrics were effectively prepared by in-situ incorporation of silver nanoparticles (Ag NPs) into the fabric matrix. Cotton and wool fabrics were used as natural fabrics and trisodium citrate was utilized as reductant for Ag + and stabilizer for Ag NPs. The formation of Ag NPs in the residual solutions was confirmed by UV/Vis spectra. Ag NPs on fabrics were shown by scanning electron microscopy and their size was in range of 20–90 nm and 70–150 nm for cotton and wool fabrics, respectively. X-ray photoelectron spectroscopy confirmed the stabilization action of citrate. As a result of surface plasmon resonance of Ag NPs, colored fabrics were produced with good fastness properties. Functional properties of treated fabrics indicate that, the in-situ incorporation of Ag NPs into fabric matrix was simultaneously imparted multiFunctional properties (colorant, antibacterial action and UV-protection) into natural fabrics concurrently.

A Textile-based triboelectric nanogenerator with humidity-resistant output characteristic and its applications in self-powered healthcare sensors
Nano Energy, 2018Co-Authors: Yun Ting Jao, Po Kang Yang, Che Min Chiu, Yu Jhen Lin, Shuo Wen Chen, Dongwhi Choi, Zong-hong LinAbstract:Abstract Functional Textiles have evoked great attention due to their promising applications in next-generation wearable and biomedical electronics. However, the constraints on the harsh operation environment and ineffective response to instantly reflect the physical status remain critical challenges. Herein, we develop a chitosan-based triboelectric nanogenerator (C-TENG) to harvest biomechanical energy from human motions, in which a nanostructured chitosan-glycerol film is utilized to promote the commercial Textile into a multi-Functional Textile based on its transparency, flexibility, biocompatibility and adaptability to commercial fabrics. The output characteristics of the as-fabricated C-TENG are notably stable under various humidity conditions, distinguishing them from conventional TENGs. As the relative humidity (RH) changes from 20% to 80%, the electric output of the C-TENG remains unchanged, in contrast to the performance degradation observed for conventional TENGs. Moreover, the C-TENG can be further developed into various kinds of self-powered healthcare sensors for humidity, sweat, and gait phase detection. More importantly, the designed humidity sensor based on the C-TENG exhibits a promising advancement in sensitivity compared with conventional TENG-based humidity sensors. This work presents a new step in applying multi-Functional Textiles to wearable energy harvesters and self-powered sensors, which have high potential for future smart clothing products and personalized healthcare sensors.
