“…To improve the interaction between the binder and fiber, chemical modifications (Dányádi et al, 2010;Guo et al, 2016;Lee et al, 2019) (i.e., ionic, electrostatic, polar, and van der Waals forces exerted on the fiber and adhesive) and physical modifications of the fiber surfaces (Song et al, 2010), which increase the roughness and specific surface area of the fibers, have been widely used (Adekunle, 2015). However, these modifications lead to the physicochemical damage of the fibers and thus the mechanical weakness of the product if the modification time is extensive (Baiardo et al, 2004;Carvalho et al, 2010;Favaro et al, 2010;Das et al, 2015;Pandey et al, 2015). Another approach to increasing the interaction between the fibers is to fabricate hairy and fuzzy fibers based on the adhesion of finely sized nanomaterials to the surface of the fibers (Juntaro et al, 2008;Pommet et al, 2008;Lee et al, 2012;Arévalo and Peijs, 2016;Fortea-Verdejo et al, 2016).…”
