Effect of Geometrical Yarn Parameters: Conventional and Compact Ring Spinning on Certain Functional Properties of TiO2NPs Treated Woven Cotton Fabrics

Abstract

N ANOTECHNOLOGY became a core of many research works specially in textiles field as it is being applied to obtain such effective properties that were not exist until its applications in smart textiles. The development of fibers spinning techniques have created a relationship between the geometrical parameters of yarns and performance properties of the resulted fabrics. Fabrics woven using compact cotton yarns found to have better UV protection and water-vapor transmittance than those of combed yarns. The compactness, evenness and low hairiness of such yarns have created an integrated structure that enhanced fabrics UV protection and water-vapor passage through fabrics. TiO 2 NPs have improved total fabrics performance specially for UV protection, while samples of compact yarns had a better result for both 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.…”
