Nanoparticles gained much scientific attention in the past decade due to their specific surface chemistry and properties which are significantly different from that of the corresponding bulk materials. Silver nanoparticles were the most extensively studied and they can be already found in a wide range of commercially available products. This article reviews the latest developments in finishing of textile materials with differently synthesized silver nanoparticles. Although antimicrobial activity of functionalized textile materials was primarily discussed, the possibilities to apply silver nanoparticles as a colorant or antistatic agent were also evaluated. In addition, the effect of chemical and physico-chemical activation of fibers before loading of silver nanoparticles on their binding efficiency was considered. Taking into account the importance of environmental impact of novel technologies, potential environmental risks emerging from silver release during washing of textile materials have been also discussed. 相似文献

The application of nanocoatings in the textile finishing is increasingly being explored because they open a whole new vista of value-addition possibilities in the textile sector. In the present work, low temperature pulsed DC magnetron sputtering method was used to create functional TiO2 nanocoatings on poly(lactic acid) textile fibres surfaces. In this study, the principal objectives in the application of TiO2 nanocoatings to textile materials are to impart UV protection functions and self-cleaning properties to the textile substrates. The TiO2 films were characterized by X-ray diffraction, scanning electron microscopy, atomic force microscopy, transmission electron microscopy, UV-visible spectroscopy and contact angle analysis. The Photocatalytic activity of the films was tested by measuring the photodegradation rates of rhodamine-B dye aqueous solution under UV light irradiation. The ultraviolet protection function was tested according to the Australian/New Zealand standards. It was observed that the TiO2 nanocoatings on poly(lactic acid) fibres showed an excellent ultraviolet protection (> 40) function and the photocatalytic efficiency was maintained even after a strong washing treatment. 相似文献

Metallization is one of the finishing processes in textile treatment that can produce multifunctional effects. The present study dealt with the development of an antibacterial polyester-knitted fabric via facile and green impregnation of silver nanoparticles (SNPs). This was done by applying a polymeric foundation on the polyester-knitted fabric by simply dip-coating in the aqueous solution of dopamine. Then the SNPs were in situ fabricated and impregnated on the surface of polydopamine-modified polyester-knitted fabric in an aqueous solution of AgNO3 at room temperature. Thus, a multi-functional finishing of polyester-knitted fabric was done. The Fourier transform infrared spectroscopy was done to confirm the polymer attachment. Scanning electron microscopy equipped with energy dispersive X-ray was done to confirm the presence of SNPs on treated fabric. The crystallography of the treated surface was examined by X-ray diffraction. The antibacterial properties of treated fabrics against broad spectrum bacterial strains were investigated and found significant. 相似文献

Adhesive metallization of filter media by means of vacuum arc technology Textile filter media made of high‐performance fibres are used for separation of pollutants from industrial exhaust gases with higher temperatures. PVD‐coating is an innovative process for antistatic finishing of high‐temperature resistant textiles. PVD‐metallizations are extremely adherent, conductive and does not affect the throughput of gas. The results are the base for the industrial use in different textile applications. 相似文献

Dielectric Barrier Discharge for the Treatmentof Sun Protection Fabrics In order to optimize the performance properties of textiles, in particular with respect to resistance toward sun light, about 60 percent of the awning fabrics produced at Schmitz‐Werke are pretreated by means of atmospheric pressure plasma. Focus of the current development efforts is to find new potentials for the products of tomorrow by exploitation of the possibilities using innovative combination processes. In addition, the aim is to further improve existing fabric materials with respect to both visual and functional properties. Formerly sun protection fabrics were made of yarns of pure cotton and later also of polyacrylonitrile. For awning fabrics polyester yarns have gained importance have been modified by a combination of a plasma treatment and nanotechnology including advanced textile auxiliaries and finishing processes to produce a modern and robust sun protection system. 相似文献
