“…Simply adding nanoparticles that can tune the reflectance spectra of pigment shades can be a cost-effective solution without increasing the amount of dyes and pigments [ 30 ]. Inorganic materials such as metals, metal oxides and metal compounds are often chosen because they do not absorb radiation in the mid-IR spectrum as with traditional organic dyes and are, thus, inconsequential to the IR transparency of the composite even in increased concentrations [ 31 , 32 ]. Salehi et al investigated the visible and NIR camouflage of viscose/polyester fabrics printed with two mineral pigments (carbon black (CB) and activated carbon nanoparticles) added to green and black vat and disperse printing pastes [ 23 ].…”

“…Therefore, the authors concluded that a 1% concentration of ZrO 2 with 6% citric acid coating applied to the cotton/nylon fabrics was suitable for imitating the reflectance of woodland and desert environments in the NIR and SWIR regions, had an acceptable visual color difference compared to the standard fabric sample, and performed well in washing and rubbing fastness tests with ratings higher than 4 out of 5 for rubbing fastness. In a separate study, Siadat and Mokhtari coated jungle and desert pattern printed cotton/nylon fabrics in a similar manner, this time with nano ZrO 2 and magnesium oxide (MgO) [ 32 ]. The padding solution contained 0.5%, 1%, 1.5%, and 2% ( w / v (%)) of the metal oxide nanoparticles and a citric acid crosslinking agent of 6% ( w / v (%)).…”

Protective textiles used for military applications must fulfill a variety of functional requirements, including durability, resistance to environmental conditions and ballistic threats, all while being comfortable and lightweight. In addition, these textiles must provide camouflage and concealment under various environmental conditions and, thus, a range of wavelengths on the electromagnetic spectrum. Similar requirements may exist for other applications, for instance hunting. With improvements in infrared sensing technology, the focus of protective textile research and development has shifted solely from providing visible camouflage to providing camouflage in the infrared (IR) region. Smart textiles, which can monitor and react to the textile wearer or environmental stimuli, have been applied to protective textiles to improve camouflage in the IR spectral range. This study presents a review of current smart textile technologies for visible and IR signature control of protective textiles, including coloration techniques, chromic materials, conductive polymers, and phase change materials. We propose novel fabrication technology combinations using various microfabrication techniques (e.g., three-dimensional (3D) printing; microfluidics; machine learning) to improve the visible and IR signature management of protective textiles and discuss possible challenges in terms of compatibility with the different textile performance requirements.

Kişisel termal yönetimin sağlanmasına yönelik, değişen vücut ve çevre şartlarına adapte olabilen pasif ve aktif akıllı tekstil yapıları ile artırılmış konfor ve azalan enerji gereksinimi gibi konularda avantajlar sağlanabilmektedir. Bu çalışmada, dünya için gün geçtikçe önem kazanan enerji kısıtlarına bağlı olarak, ekstra enerji harcanmadan doğal radyasyon enerji bileşenleri (ultraviyole, görünür, infrared) ve mekanizmalarının (yayılım, yansıtma, absorpsiyon, geçirgenlik) yönetimiyle vücudun termal dengesini ısıtma/soğutma veya ısıtma-soğutmayı birlikte sağlayarak koruyan yapılar, etkili radyasyon ısı transfer mekanizmaları ışığında incelenmiştir. Bu tür pasif akıllı yapılar için kullanılan ölçüm yöntemleri, mevcut çalışmaların eksik noktaları ve ilerleme yönü konularında da literatür ışığında değerlendirmeler yapılmıştır. Mevcut çalışmaların son dönemde, küresel ısınmanın etkilerinin de somut olarak hissedilmesiyle birlikte, radyasyonla iç ortamlarda kişisel soğutma konusunda yoğunlaştığı, dış ortamda geçerli olan karmaşık mekanizmaların tasarım ve ölçümleri zorlaştırdığı sonucuna varılmıştır. Ayrıca, çalışmalarda yapıların giyilebilirlikleri açısından önemli olan tutum, konfor ve radyasyon dışındaki ısı ve kütle transfer mekanizmalarının bütüncül olarak incelenmeleri konusunda eksiklikler tespit edilmiştir. Çalışmalar, konfor ve enerji tasarrufu beklentilerinin hızla değiştiği günümüzde radyasyon enerjisi yönetimiyle ısıtma/soğutma yapan yapıların vücut ve ortam koşullarına otonom olarak uyum sağlayabilecek şekilde tasarlanması yönünde ilerlemektedir.
