“…All of the samples exhibited absorption coefficients greater than 0.5 for frequencies from 2000 Hz to 5000 Hz when the surface density was above 0.093 g/cm 2 . The sound absorption properties of poplar seed, kapok, wool, hemp and cotton have been reported, and the average sound absorption coefficients of these five samples were 0.225, 0.095, 0.273, 0.385 and 0.38, 34 much lower than that of the windmill palm fiber with the same thickness. It can be seen in Figure 2(a) and (c) that the sound absorption performances of alkali and acetic anhydride-treated fibers were poor at the surface density of 0.047 g/cm 2 .…”

Windmill palm fiber, a high-quality cellulose resource, can be extracted from discarded palm sheath. However, the application of this abundant biomass in composite reinforcement is limited due to its hydrophilicity. In this study, the effects of chemical modifications, such as treatment with alkali, acetyl chloride, and acetic anhydride, on the micro-morphology, water repellence, sound absorption, thermal conductivity, and thermal stability of windmill palm fiber have been investigated. The results showed the surface of windmill palm fiber treated with alkali to be relatively long, thick, and smooth. In comparison, acetylation treatment destroyed the cell walls, leaving micro-holes in the surface. Acetylation modification significantly improved the water repellence of the fibers, increasing the water static contact angle to more than 145°. Acetylation treatment also improved the sound absorption performance of a fiber mat, giving an average sound absorption coefficient of 0.47, maintained a low thermal conductivity of under 0.050 W/m/K, and improved the thermal stability, raising the initial decomposition temperature to above 350°C.

“…The CTF fibers were equilibrated under standard conditions, i.e. 20 °C temperature and 65% RH for 48 h 19 . To measure the fiber diameter, 3 random places of 100 fibers were measured by an optical microscope, and longitudinal direction images were taken from distinct fiber samples.…”

This study deals with the determination of new natural fibers extracted from the Corypha taliera fruit (CTF) and its characteristics were reported for the potential alternative of harmful synthetic fiber. The physical, chemical, mechanical, thermal, and morphological characteristics were investigated for CTF fibers. X-ray diffraction and chemical composition characterization ensured a higher amount of cellulose (55.1 wt%) content and crystallinity (62.5%) in the CTF fiber. The FTIR analysis ensured the different functional groups of cellulose, hemicellulose, and lignin present in the fiber. The Scherrer’s equation was used to determine crystallite size 1.45 nm. The mean diameter, specific density, and linear density of the CTF fiber were found (average) 131 μm, 0.86 g/cc, and 43 Tex, respectively. The maximum tensile strength was obtained 53.55 MPa for GL 20 mm and Young’s modulus 572.21 MPa for GL 30 mm. The required energy at break was recorded during the tensile strength experiment from the tensile strength tester and the average values for GL 20 mm and GL 30 mm are 0.05381 J and 0.08968 J, respectively. The thermal analysis ensured the thermal sustainability of CTF fiber up to 230 °C. Entirely the aforementioned outcomes ensured that the new CTF fiber is the expected reinforcement to the fiber-reinforced composite materials.

“…Biological fibers, a kind of abundant renewable fibers, are obtained from wild plants, agricultural and forestry resources, and animal and municipal wastes and have the characteristics of abundant resource, low cost, and environment-friendly. − Their special surface, structure, and natural chemical composition are in accord with the current concept of carbon neutral production and economic sustainable development, which have attracted more and more attention and exhibited great potential for application in many fields. In recent years, the Calotropis gigantea fiber, kapok, cattail fiber, straw and rice straw fiber, and floss obtained from poplar seeds have been used in many fields because of their unique morphological structures and biodegradability. − Take C. gigantea fibers, also called vegetable silk, for example, they are harvested from the seeds in the plant pods and have been successfully used in traditional textile and other fields, such as medical fabrics, flexible wearable electronics, oil-absorbing materials, and even in the reinforcement of lightweight composite materials due to their special cavity structure. − …”

Miscanthus floridulus fibers obtained from the seed floss of M. floridulus (a perinneal plant of Gramineae native to Africa and Asia and widely distributed in tropical and subtropical regions) have potential application value in textile and other fields. At present, the biological characteristics and ecological benefits of Miscanthus floridus have been extensively studied by researchers, but there have been no literature on M. floridus fibers. In order to make reasonable use of M. floridus fibers, their morphological structure, physical properties, chemical composition, thermal insulation properties, and surface absorption properties were explored in detail in this study. The results showed that the M. floridus fiber is fine and short and has a hollow structure with a density of 0.67 g cm –3 . Chemical analyses revealed that the main constituents of the fiber are cellulose (66.98%), hemicelluloses (13.86%), lignin (6.97%), pectin (1.99%), and wax (4.38%). The fill power and warmth retention performance of the fiber are similar to those of wool. In particular, the M. floridus fiber surface has hydrophobic and lipophilic properties with a static contact angle of 123.7° for water droplets in equilibrium. Therefore, the M. floridus fiber has a promising application prospect in bulk textile thermal insulation and oil–water separation fields.
