Over the past decade, significant progress has been made in creating environmentally friendly products using natural resources. Plant fibers, also known as lignocellulosic fibers, are hydrophilic due to the interaction and attraction between water molecules and the hydroxyl groups present in their components. The inherent hydrophilicity of plant fibers often prevents them from interacting effectively with hydrophobic polymer matrices. In order to improve the adhesion between plant fibers and the matrix, it is necessary to modify the surface of the fibers. Commonly used chemical processes include mercerization, silane treatment, acetylation, permanganate treatment, acrylation, benzoylation, peroxide treatment, stearic acid treatment, isocyanate treatment and sodium chlorite intervention. The desirability of chemically modifying the surface of plant fibers has declined due to several limitations. Plant fibers can be modified in an environmentally friendly way by various methods, such as plasma therapy and treatments using fungi, enzymes and bacteria. This part provides an analysis of the impact of different environmentally friendly surface modification techniques on the properties of plant fibers and reinforced polymers.

“…Similar results were obtained in chemically grafted co‐polymerizations of various vinyl monomers on natural fibres [6] . Based on the comparison study of silane coupling agents and other vinyl monomers, it can be concluded that silane‐coupling agents are suitable grafting monomers for viscose fibres under the conditions established [25,39] . By varying the pH from 2.5 to 6 while maintaining constant monomer concentration, temperature, time, and ethanol‐water ratio, the impact of pH on weight gain was examined.…”

“…After being treated with silane coupling agents, the hydrophilic properties of viscose fibre decreased, and as a result, there was less swelling in the polar solvents. Moreover, the modified fibre develops a hydrophobic surface that repels moisture and has a lower affinity for moisture than the original fibre [25,46,47] …”

“…The functionalization of the free hydroxyl groups in the fibre eventually causes the chemical alteration to lessen the hydrophilic characteristic of the cellulosic fibres. [16][17][18][19][20] The literature has described a number of chemical techniques like acetylation, [21,22] peroxide treatment, [23,24] and the use of silane coupling agents [25][26][27] used to modify viscose fibres. For instance, in order to improve the functional properties of viscose fabrics, such as antibacterial, UV-blocking, and self-cleaning capabilities, Fahmy et al [28] modified viscose fabric with various functional additives, including Ag, Silicon®-SLH softener, and TiO 2 nanoparticles, in various easy care finishing formulations separately and in admixtures.…”

The surface of viscose fabric was successfully functionalized with 3‐aminopropyltriethoxysilane (APS) and 3‐methacryloxypropyl‐trimethoxysilane (MPS) in order to optimize its physicochemical characteristics and textile performances. The functionalization was optimized with silane monomer concentrations of 600 and 300 %, ethanol‐water ratios of 60 : 40 and 80 : 20, pH 3.5 and 5, and reaction time of 90 and 60 min at 30 °C, for MPS and APS, respectively. The modified viscose fabric was characterized by FTIR, TGA, DTG, SEM, and EDX. The FTIR spectra of the MPS and APS‐modified fabrics showed additional peaks at 825 cm−1 for Si−CH2 group and 1208 cm−1 Si−O−CH3, respectively, indicating the incorporation of silane coupling agents. The degradation temperatures of MPS and APS‐modified fibres were 342 °C and 328 °C, respectively, while the value for untreated viscose fibre was 319 °C. The elemental percentage of silicone on viscose fibre after modification was 2.6 and 4.2 for MPS and APS respectively. The silane‐modified viscose fibre shown enhanced tensile strength, water repellency, thermal stability, wrinkle recovery, and improved colour fastness quality. These improvements were due to the flexibility of Si−O bond and the fibre matrix interfacial strength properties. Hence, the modification somewhat enhances the physico‐chemical characteristics of viscose fibre.

“…During hydrophobic treatment, the interaction of vinyltriethoxysilane with cotton fabrics mainly proceeds through four steps: (a) silane coupling agent hydrolysis; (b) self-condensation; (c) adsorption; and (d) dehydration as shown in Figure 2(a). [25][26][27] Therefore, hydrophobic cotton fabrics were formed by replacing hydroxyl groups (-OH) on cotton fibers with silanes. Through the following radical induced surface polymerization of acrylic acid, sufficient carboxyl groups (-COOH) were formed.…”

Wet comfort is an important indicator for evaluating human wearing comfort, and personal moisture management fabrics can quickly transfer sweat from the skin surface to meet the human body's requirements for wet comfort. Although cotton fabrics have an excellent water absorption capacity, the inability of moisture to transfer quickly causes the fabrics to cling to the skin and causes discomfort. Here we demonstrate personal moisture management cotton fabric by two-step grafting treatments, which are relatively simple and usually do not fall off as easily as a simple coating process. Moreover, unlike traditional double-layer or sandwich structures that absorb water and grow heavy, the fabric's quick-drying qualities are accomplished by expanding the area of water evaporation. According to the results of liquid moisture management and water evaporation rate tests, this fabric's moisture diffusion radius is 5 mm larger than that of pure cotton fabrics, and its evaporation rate can reach 0.2082 g/(m2 · d). In addition, it is also suitable for high-volume apparel fabrics. This work paves the way for personal moisture management cotton fabric.
