“…The efficacy of the self-cleaning effect is enhanced in samples that are coated with greater quantities of TiO2 [68]. Additional components used in the development of self-cleaning coatings include oil palm boiler ash (OPBA), chitosan, and cellulose nanofibers (CNFs) [69][70][71]. Besides, these coatings include antibacterial, UV-blocking, and persistent scent-release qualities [70].…”

In recent times, there has been a discernible focus on the development of environmentally friendly and sustainable biomaterials obtained from renewable sources. Scientists are now investigating the prospective applications of nanocellulose, a biocompatible substance derived from natural cellulose. The aforementioned substance exhibits notable characteristics, such as a substantial surface area to volume ratio, with its compatibility with biological systems and capacity to undergo degradation. Nanocellulose has the capability to undergo transformation into nanofibers and nanocrystals, so enabling the generation of diverse structures, including elongated nanofibers, suspensions, and films. In the textile industry, there is a growing need to adopt sustainable techniques in order to address and minimize the negative environmental impacts. The current focus is on the advancement of environmentally sustainable alternatives in the realm of textile production, namely cellulose-based materials. These textiles are being created using processes that aim to minimize water pollution. In addition, recent advancements in dyeing methods have used nanocellulose to effectively reduce water consumption and eliminate the need for toxic materials. Nanocellulose nanocomposites, such as nanofibrillated celluloses (NFCs) and cellulose nanocrystals (CNCs), are increasingly used as fillers in textile nanocomposites to enhance their mechanical characteristics due to their cost-effectiveness and recyclability. The advancements achieved in the field of nanocellulose-based materials and technology exhibit considerable promise in the development of ecologically friendly solutions across several industries.

“…Surface flame-retardant treatment − is one of the most effective methods to impart flame retardancy to cotton and its blends, which is economical and suitable for industrialization. , In recent decades, many surface treatment technologies have been developed to enhance the flame retardancy of textiles, including the sol–gel technique, plasma treatment, surface grafting treatment, layer-by-layer (LbL) deposition, etc. , Among them, LbL is prominent due to its wide range of coating components and environmentally friendly features. , In general, LbL is conducted by alternately depositing positively and negatively charged species via electrostatic interactions, hydrogen bonds, covalent bonds, etc. , A variety of LbL-assembled systems, such as chitosan/phytic acid, polyethylenimine/ammonium polyphosphate (APP), and chitosan/sodium hexametaphosphate (PSP), have been applied to endow cotton fabrics and their blends with flame retardancy. Despite many benefits of the LbL assembly method, the fussy deposition processes make it difficult for large-scale production …”

Cotton and its blended fabrics are widely used textile materials in daily life; however, their high flammability brings serious fire hazards. It remains a huge challenge to endow cotton and its blended fabrics through simple and universal technology. In this work, a novel water-based polyelectrolyte complex (PEC) coating was developed from chitosan and a water treatment agent (amino trimethylphosphonic acid). By controlling the degree of ion pair aggregation through pH adjustment, the intumescent and stable PEC coating can be constructed quickly via facile blading coating and curing processes. High transparency allows for the deposition of the coating with little effect on the original pattern of the coated fabric. Additionally, when the coated fabrics were exposed to flame, the PEC coating underwent a quick self-char-forming reaction in advance and formed a protective char layer covered on the fibers. Thus, the PEC coating with low adding-on (11.5–21.5 wt %) shows universally high flame retardancy for cotton, polyester/cotton blends, and polyester/poly(vinyl alcohol)/cotton blends. The coated fabrics show excellent extinguishing performances, high limiting oxygen index values of 27.5%–28.5%, and total release smoke inhibition of 42%. This work provides a promising universal technology for manufacturing fire-safety cotton and its blends in a simple and eco-friendly way.
