“…The three types of fibers are present in this band before and after the solvent treatment procedures. All fibers depict a set of bands in the range of 2950-2800 cm −1 , assigned to C-H asymmetric and symmetric stretching vibrations in methyl and methylene groups present in polysaccharides (cellulose [40,41], pectin and hemicellulose [35,42]). Lipids and fatty acids also contribute to the intensity of these bands, due to their hydrocarbon chain content in these compounds [4,29,35,43].…”

This paper presents an optimized washing protocol for as-received natural fibers, prior to large-scale composite manufacturing, for the structural strengthening of historic masonry. The aim was to achieve a simple protocol for standard cleaning of fiber surfaces from low molecular weight constituents that may be detrimental towards interfacial strength without damaging the fibers. The proposed procedure employs the application of the solvent sequence: ethanol, acetone, hexane, with optimized incubation times and stirring conditions. Additionally, this procedure may change the surface of the fiber, thereby enhancing the durability of the fiber-matrix interface. The washing protocol resulted in an increase of tensile strength by 56%, 52% and 22% for flax, hemp and sisal fibers, respectively, as compared to the corresponding non-washed fibers, without loss of elongation. The static contact angle measurements confirmed exposure of a higher fraction of the hydrophilic crystalline cellulose, with a higher wettability observed after washing protocols.
