Weave Structure and Fabric Properties
Fabric structures are created by interlacing yarns or intermeshing loops to create two-dimensional (2D) flexible materials. The most prevalent structure is woven fabrics, which are made up of two sets of perpendicular yarns that are crossed and interwoven to form a coherent and stable structure.

Fabrication Processes of Conductive Textiles
Wearable electronics are gaining popularity as a platform for the next generation of human-friendly electronic devices. Therefore, a new class of devices with various functionality and amenability for the human body is essential. Traditional textile materials, such as fiber, yarn, and fabric, are non-conductive. Innovative methods and novel processing technologies have been introduced to impart conductivity in textile materials to solve this issue. Coating, printing, deposition, and in situ polymerization are common techniques for this purpose. Here, the newly developed methods with significant potential are summarized, which includes their conductivity level in different applications, such as batteries, displays, and sensors.

Microelectronics for E-Textile
Modern electronic textiles are moving towards flexible wearable textiles, so-called e-textiles that have micro-electronic elements embedded onto the textile fabric that can be used for varied classes of functionalities. There are different methods of integrating rigid microelectronic components into/onto textiles for the development of smart textiles, which include, but are not limited to, physical, mechanical, and chemical approaches. The integration systems must satisfy being flexible, lightweight, stretchable, and washable to offer a superior usability, comfortability, and non-intrusiveness. Furthermore, the resulting wearable garment needs to be breathable.

Temperature Sensors for Thermoregulation in Personal Protective Equipment
The exposure to extreme temperatures in workplaces involves physical hazards for workers. A poorly acclimated worker may have lower performance and vigilance and therefore may be more exposed to accidents and injuries. Due to the incompatibility of the existing standards implemented in some workplaces and the lack of thermoregulation in many types of protective equipment, thermal stress remains one of the most frequent physical hazards in many work sectors. In order to provide a better protection of individuals against thermal aggressors, the scientific community has been interested in the development of the textile-based or flexible temperature sensors that can be integrated into personal protective equipment. These sensors can measure the skin temperature and monitor the microclimate temperature between the body and the clothing or the outside temperature during exposure to thermal aggressors.

Application of Cyclodextrins in the Textile Area
Cyclodextrins (CDs) are biocompatible and accepted in biological applications; therefore, there is a growing interest in them both scientifically and industrially. CDs are obtained through the enzymatic degradation of potatoes, corn and rice starch, which gives a mixture of linear, branched, or cyclic dextrins. CDs have a very important role in textile processing and innovation; their use provides immediate opportunities for the development of environmentally friendly products and eco-textiles, in addition to having great potential in various applications. Cyclodextrins can be applied in the areas of spinning, pretreatment, dyeing, finishing, and dye removal, with dyeing, finishing, and water treatment being the most applicable in the textile area registered so far.

Textile-Based Mechanical Sensors
Innovations related to textiles-based sensors have drawn great interest due to their outstanding merits of flexibility, comfort, low cost, and wearability. Textile-based sensors are often tied to certain parts of the human body to collect mechanical, physical, and chemical stimuli to identify and record human health and exercise. Until now, much research and review work has been carried out to summarize and promote the development of textile-based sensors. As a feature, we focus on textile-based mechanical sensors (TMSs), especially on their advantages and the way they achieve performance optimizations

Advancements in Natural Dyes Extraction
The dyeing and finishing step represents a clear hotspot in the textile supply chain as the wet processing stages require significant amounts of water, energy, and chemicals. In order to tackle environmental issues, natural dyes are gaining attention from researchers as more sustainable alternatives to synthetic ones. The extraction of colorant from natural sources is a fundamental step in preparing purified natural dyes, as a plant’s matrix contains only a small percentage of dye, usually in the range of 0.5–5%, and several other constituents such as water-insoluble fibers, carbohydrates, protein, chlorophyll, and tannins, among others. The selection of the most suitable extraction technique should be based on the evaluation of the nature and solubility of the dyeing materials.

Layer-by-Layer Deposition to Reduce Flammability of Textiles
Layer-by-layer (LbL) deposition is an emerging green technology to reduce flammability of the most widely used fibers (cotton, polyester, polyamide and their blends), which shows numerous advantages over current commercially available textile finishing processes due to the use of water as a solvent for a variety of active substances at very low concentrations. The LbL deposition includes immersing textiles into the solutions of oppositely charged polyelectrolytes or spraying textiles with charged solutions to build LbL assemblies with the desired number of bilayers (BLs), trilayers (TLs), or quadlayers (QLs) with different functionality. In conventional LbL deposition, layers are attracted by weak electrostatic forces of polyelectrolytes soluble in water, polyanions and polycations with one charged group per monomer unit, but polymers bearing hydrogen bond donors and acceptors are also able to form assemblies.

Textile-Integrated Thermocouples
The integration of conductive materials in textiles is key for detecting temperature in the wearer´s environment. When integrating sensors into textiles, properties such as their flexibility, handle, and stretch must stay unaffected by the functionalization. Conductive materials are difficult to integrate into textiles, since wires are stiff, and coatings show low adhesion. This work shows that various substrates such as cotton, cellulose, polymeric, carbon, and optical fiber-based textiles are used as support materials for temperature sensors. Suitable measurement principles for use in textiles are based on resistance changes, optical interferences (fiber Bragg grating), or thermoelectric effects.

Washing Damage in E-Textiles
E-textiles, hybrid products that incorporate electronic functionality into textiles, often need to withstand washing procedures to ensure textile typical usability. Yet, the washability—which is essential for many e-textile applications like medical or sports due to hygiene requirements—is often still insufficient. The influence factors for washing damage in textile integrated electronics as well as common weak points are not extensively researched, which makes a targeted approach to improve washability in e-textiles difficult.

Flexible Textile-Based Sweat Sensors for Wearable Applications
The physical health care system has gradually evolved into a form of virtual hospitals communicating with sensors, which can not only save time but can also diagnose a patient’s physical condition in real time. Textile-based wearable sensors have recently been identified as detection platforms with high potential. They are developed for the real-time noninvasive detection of human physiological information to comprehensively analyze the health status of the human body. Sweat comprises various chemical compositions, which can be used as biomarkers to reflect the relevant information of the human physiology, thus providing references for health conditions. Combined together, textile-based sweat sensors are more flexible and comfortable than other conventional sensors, making them easily integrated into the wearable field.

Antimicrobial Masks as Personal protective equipment
Shortage of personal protective equipment (PPE) is often projected in response to public health emergencies such as infection outbreaks and pandemics. Respiratory protective devices (RPDs), namely medical face masks and respirators, are considered the last defence for the front-line healthcare workers. To contribute to the mitigation of RPDs shortage, new technology such as antimicrobial treated PPE that can reduce the risks of fomite during the donning and doffing process with an extended lifespan gets increasingly prevalent.
