“…Chromic textiles are fabrics or fibers that change color depending on the type of external stimulus. Several works have been addressed to develop these textiles since their use as smart materials [80]. The thus obtained nanocellulose-dye product gave stable suspensions that change color from orange to purple, increasing the pH from acid to alkaline.…”

“…Chromic textiles are fabrics or fibers that change color depending on the type of external stimulus. Several works have been addressed to develop these textiles since their use as smart materials [ 80 ]. Of particular interest for environmental monitoring could be ionochromic textiles, but, until now, very few studies are reported for application in this field.…”

Environmental contamination affects human health and reduces the quality of life. Therefore, the monitoring of water and air quality is important, ensuring that all areas are acquiescent with the current legislation. Colorimetric sensors deliver quick, naked-eye detection, low-cost, and adequate determination of environmental analytes. In particular, disposable sensors are cheap and easy-to-use devices for single-shot measurements. Due to increasing requests for in situ analysis or resource-limited zones, disposable sensors’ development has increased. This review provides a brief insight into low-cost and disposable colorimetric sensors currently used for environmental analysis. The advantages and disadvantages of different colorimetric devices for environmental analysis are discussed.

“…Structures that are able to independently evaluate the state of the environment and respond appropriately to it are then referred to as intelligent. Smart textiles are textile structures that are sensitive to external stimuli (various types of radiation, pH, mechanical magnetic or electric fields) and, depending on changes in these stimuli, react reversibly (usually by changing porosity, color [ 2 , 3 ] and shape, among others). Textiles with only multifunctional effects have special properties (e.g., antibacterial activity, ultraviolet protection, electromagnetic shielding, photocatalytic self-cleaning) [ 4 , 5 ], but not reversible reactions.…”

Sandwich Structures Reflecting Thermal Radiation Produced by the Human Body

Far infrared (FIR) textiles are a new category of functional textiles that have presumptive health and well-being functionality and are closely related to human thermo-physiological comfort. FIR exerts strong rotational and vibrational effects at the molecular level, with the potential to be biologically beneficial. In general, after absorbing either sunlight or heat from the human body, FIR textiles are designed to transform the energy into FIR radiation with a wavelength of 4–14 μm and pass it back to the human body. FIR textiles can meet increased demand for light, warm, comfortable, and healthy clothing. The main aim of this research is to describe the procedure for creating the FIR reflective textile layer as part of multilayer textile structures that have enhanced thermal protection. To develop the active FIR reflecting surface, the deposition of copper nanolayer on lightweight polyester nonwoven structure Milife, which has beneficial properties of low fiber diameters, good shape stability and comfort, was used. This FIR reflective layer was used as an active component of sandwiches composed of the outer layer, insulation layer, active layer, and inner layer. The suitable types of individual layers were based on their morphology, air permeability, spectral characteristics in the infra-red region, and thermal properties. Reflectivity, transmittance, and emissivity were evaluated from IR measurements. Human skin thermal behavior and the prediction of radiation from the human body dependent on ambient conditions and metabolic rate are also mentioned. The FIR reflective textile layer created, as part of multilayer textile structures, was observed to have enhanced thermal protection.

“…The research on preparation and application of photochromic materials has attracted extensive attention due to their obvious and rapid color change, being widely applied in optical information storage [ 1 ], chemical sensors [ 2 , 3 ], molecular switches [ 4 ], information security encryption [ 5 ] and smart textiles [ 6 ], etc. Accordingly, various photoswitchable molecules-azobenzenes [ 7 ], spiropyrans [ 8 ], diarylethenes [ 9 ], fulgides [ 10 ] and others [ 11 , 12 ] have been widely investigated and employed for the construction of light-responsive systems and materials.…”

“…It is broadly applied as fiber, textile and engineering plastic materials. In textile field, photochromic polyamide materials such as PA fibers or PA fabric are acquired by dyeing or coating with photochromic dyes on their surfaces [ 6 , 30 ]. The photoresponse fatigue resistance and cyclic usage performance need to be improved.…”

Photochromic Polyamide 6 Based on Spiropyran Synthesized via Hydrolyzed Ring-Opening Polymerization

et al. 2021

We report photochromic polyamide 6 (PA6) which was synthesized by hydrolyzed ring-opening polymerization of ε-caprolactam with spiropyran (SP) embedded in the polymer chains. It indicated that crystallinity degree of the resulting copolymers was decreased since only PA6 segments can crystallize with increasing content of SP modifier. Meanwhile, toughness of photochromic PA6 was decreased. The photochromic property analysis indicated that the sample with more flexibility and more content of SP was more sensitive to UV light at the beginning of irradiation than other samples and its color after being irradiated for 1 min tended to reddish. Investigation revealed that the UV-vis absorbance of SP-PA6-3 had negligible decay after 10 cycles, which indicated SP-modified PA6 possessed excellent photoresponse reversibility and fatigue resistance.
