“…Elemental analysis can detect low DS, but due to its high sensitivity then impurities in the material can create false results. Therefore, we estimated the DS by chemically grafting the MPA‐fabrics with cysteamine hydrochloride to obtain thiol end groups on the surface of the fabrics followed by application of the Ellman's reagent test to quantify these end groups 44–46 . In the presence of thiol functional groups, the disulfide bond of Ellman's reagent undergoes dissociation and creates a new covalent disulfide bond with the fabric; this is accompanied by the release of 2‐nitro‐5‐thiobenzoic acid.…”

A modular method for functionalization of nonwoven fabrics was developed using a two-step process. In the first step, the fabrics were grafted with a linker molecule, 10-undecenoyl chloride, via esterification, followed by attachment of a functional material under UV irradiation. Perfluorodecanethiol and 3-mercaptopropionic acid (MPA) were connected to the linker-modified fabrics using thiol-ene click chemistry. Perfluorodecanethiol modified fabrics exhibited hydrophobicity with water contact angle of about 140 while MPAmodified fabrics were able to lower the pH of a solution by about 1.6. We additionally demonstrated the possibility to connect functional polymers to the linker-modified fabrics by radical graft polymerization of acrylic acid; this produced a thin layer of the polymer on the surface of the fabric. Fabrics modified with poly(acrylic acid) exhibited increased hydrophilicity with water contact angle of 0 for both cotton and viscose-polyester fabrics, while the water absorption capability for polypropylene fabrics increased from about 50 to 1200%.

This review addresses the reconstruction of structural plant components (cellulose, lignin, and hemicelluloses) into materials displaying advanced optical properties. The strategies to isolate the main building blocks are discussed, and the effects of fibrillation, fibril alignment, densification, self‐assembly, surface‐patterning, and compositing are presented considering their role in engineering optical performance. Then, key elements that enable lignocellulosic to be translated into materials that present optical functionality, such as transparency, haze, reflectance, UV‐blocking, luminescence, and structural colors, are described. Mapping the optical landscape that is accessible from lignocellulosics is shown as an essential step toward their utilization in smart devices. Advanced materials built from sustainable resources, including those obtained from industrial or agricultural side streams, demonstrate enormous promise in optoelectronics due to their potentially lower cost, while meeting or even exceeding current demands in performance. The requirements are summarized for the production and application of plant‐based optically functional materials in different smart material applications and the review is concluded with a perspective about this active field of knowledge.

“…One of these functional textile categories is photochromic textiles which can change their color under ultraviolet (UV) irradiation. Owing to color changing features, photochromic textiles have potential for use both for fashion effects and in smart textile applications such as sensors, [1][2][3][4] UV protection, [5][6][7][8][9] brand protection, 10 and so on. Photochromic textiles appeared in the field in the 1990s 11,12 and can be produced in the form of photochromic fiber/ yarn by the incorporation of photochromic dyes into the polymer matrix during the production of synthetic fibers.…”

“…However, there are few studies on the UV protective properties of photochromic textile materials. 5,8,9 Therefore, another aim of this study is to observe the potential use of spray-dried photochromic microcapsules for the production of UV protective textile materials. Although the sun is an indispensable source of life for all living beings, UV rays, which make up 5% of the sun rays reaching the earth, are a serious threat in terms of general human health, especially for people who have to work under the sun, children playing outdoors, and people involved in sports outdoors.…”

Photochromic textiles, a class of functional textiles, have a color build up feature under ultraviolet light irradiation. However, photochromic dye application onto textile materials by conventional finishing techniques has difficulties due to their low water solubility and low affinity to the textile materials. Encapsulation technology could be used to overcome these problems in the production of photochromic textile materials. This article, which is the third in a three-part series, deals with the application of photochromic dye microcapsules produced by a spray drying method onto cotton fabrics. The photochromic dye microcapsules were applied onto cotton fabrics by a pad–dry–cure process. Color build up and ultraviolet transmittance of the resultant photochromic fabrics were evaluated after the application and consecutive washing. Moreover, the fatigue resistance of the photochromic fabrics was studied and the effects of the incorporation of hindered amine light stabilizers into microcapsules were investigated. Ultraviolet protection factor values of the samples were found to be 50+ even after 20 washing cycles. It was shown that the photochromic fabrics have a loss of 10% in ultraviolet protection factor values and 20% in color values after 20 ultraviolet irradiation cycles and the fatigue resistance of the photochromic dye capsules improved with the use of hindered amine light stabilizer compounds during microcapsule production.
