Abstract
ABSTRACT The demand for fabric comfort in common textiles is increasing and is closely associated with transmission properties. In this study, three common cloths namely 100% cotton, polyester-cotton blended (50% each), and 100% polyester were treated with copper nanomaterial and its influence on air, water, electrical resistance, and ultraviolet (UV) transmittance properties was studied. Cotton fabrics showed improvement (by 18%) in air permeability and moisture transmission. The UV transmission was restricted between 300 and 400 nm for all fabric samples. The surface electrical conductivity of treated polyester fabrics was 40.38 Ω−1 m−1 × 10−9. The changes in transmission properties post-treatment can mainly be attributed to changes in fabric porosity, packing fraction, thickness, and cover factor. The cotton fabric showed a decrease in the cover factor; justifying results that showed improvement in its liquid moisture and air permeability. The polyester fabrics were unaffected, whilst the blended fabrics were intermediate of the two.
