The main objective of this research was to study the influence an enzymatic treatment process date palm fibers on their chemical and morphological properties as well physical mechanical characteristics composites filled with raw treated fibers. To end, three extraction approaches were considered (a combination xylanase pectinase enzymes, enzymes followed by a one enzyme xylanase). Chemical anal...

The increased surface area-to-volume ratio of nanoparticles, quantum size effects and the ability to tune surface properties through molecular modification make nanostructures ideal for environmental remediation. The present piece of work reports the preparation and characterization of nano cellulosic fibers (NCFs) with further polymeric reinforcement using vinyl sulphonic acid for the remediat...

Titania, single-doped and lanthanum-silver co-doped titania nanocomposite were coated on cellulosic and polyacrylonitrile fibers via sol–gel method. The prepared samples were evaluated using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), photolumines...

Abstract N -Methylated derivatives of α-tocopheramine, which have preliminarily been shown to good performance as stabilizers cellulose solutions in ionic liquids for production cellulosic manmade fibers, not accessible sufficient amounts by green syntheses. In this study, the -methyl-, , -dimethyl-, and -trimethylammonium α-tocopheramine were synthesized fully analytically characterized. The p...

The cellulosic fiber-based sustainable textile industry needs greener alternatives to the existing hydrophobization approaches—which are essentially based on nonrenewable and expensive hydrophobizing agents adversely impact environment. Herein, we report production of novel hydrophobic cellulose fibers produced by incorporating nature-derived additives—betulin (BE) betulinic acid (BA) using Ion...

Films of microfibrillated celluloses (MFCs) from pulps of different yields, containing varying amounts of extractives, lignin, and hemicelluloses, were produced by combining refining and high-pressure homogenization techniques. MFC films were produced using a casting-evaporation technique and the physical and mechanical properties (including density, roughness, fold endurance and tensile proper...
