Improving antibacterial and sun protective properties of cotton fabrics via dual effect of nano-metal oxide and Moringaoleifera extract

Abstract

B leACheD cotton fabrics were pre-treated with Moringa oleifera leaf extract as natural bioactive materials to impart the fabrics dual antibacterial and sun protective properties. The fabrics were the treated with titanium dioxide nanoparticles(TiO 2 NPs) and zinc oxide nanoparticles (ZnONPs) separately with concentration 2wt.% and 1 wt.% respectively in presence of 1,2,3,4-butane tetracarboxlyic acid(BTCA) as non-formaldehyde crosslinking agent by using pad dry cure method. The treated cotton fabrics were evaluated via monitoring morphological changes of the fibers by using scanning electron microscopy and X-ray diffraction, scanning electron microscopy(SEM&EDX), mechanical properties (tensile strength and elongation at break),roughness, ultraviolet protection factor (UPF). In addition, evaluation of antibacterial activity the treated fabrics by using disk inhibition zone. Research output disclosed that the fabrics treated with moringa extract and then with titanium dioxide nanometal oxide powder show the best results.

Recent Advances in Functionalization of Cotton Fabrics with Nanotechnology

“…In 2020, El-Bisiet al [ 61 ] developed cotton fabrics with improved antibacterial and ultraviolet properties after treating them with TiO 2 NPswith Moringa oleifera extract. The UPF and antibacterial properties of TiO 2 NPs cotton fabrics are improved.…”

02. Fading Characteristics of Chemically Modified Cotton Fabric Dyed with an Acid Dye

“…Also, chemical modification of cellulosic materials was frequently carried out to create active centers that impart new and /or diverse properties which increase the fabrics' applications for different end uses. Much research and technological work were done in this field to make the cellulosic fabrics acquire some additional properties such as flame retardant [1,4], antibacterial and UV protection [5][6][7][8], self-cleaning, [9][10][11][12] water /oil repellent, [13] crease and wrinkle [14][15][16] recovery. Also, to accept different classes of dyes [17][18][19][20][21][22][23][24] with remarkable improvement in dyeability and fastness properties.…”

Enhancement of Antimicrobial and Dyeing Properties of Cellulosic Fabrics via Chitosan Nanoparticles

“…Cellulosic fabrics have a moderate affinity for reactive and direct dyes in the presence of salts to increase their dye exhaustion, but they don’t have any affinity for acid dyes [ 3 , 4 , 5 ]. The addition of salts restricts the penetration of dyes inside cellulosic fabrics, causing pollution of running water [ 6 , 7 , 8 ]. On the other hand, acid dyes can replace direct and reactive dyes for cellulosic dyeing because it is cheaper and less polluting than running water.…”
