TEXTILE IMPACT PLATES FOR NANOPARTICLES

Abstract

The paper presents textile materials with destination impact plates, having different surface architectures and active treatments for functionalization, with influence upon the aging process of nano-Ag and nano-CeO2. The woven and knitted samples from 100% cotton, cotton/PES blend and 100% PES were treated by impregnation on the laboratory padding machine, drying and condensing on the machine for drying-condensing-heat setting, with the following recipes: 50g/l RUCOSTAR EEE6+20 ml 5% nano-Ag dispersion, or 10% nano-CeO2 in ethylene glycol, respectively water and 0,5ml acetic acid 60% for products from 100% cotton and PES/cotton and 50g/l NUVA N 2114 liquid with the same percent of nanoparticles but with 1 ml/l acetic acid 60%, in case of 100% PES samples. The samples were treated in 2 steps – hydrophobic/ oleo phobic in the first stage and hydrophobic/ oleo phobic/ functionalization with nano-Ag and nano-CeO2 in the second stage. The complex characterization of both type of materials : hydrophobic and oleo phobic properties, color change, whitening degree, DCS, FT-IR, SEM and microbiology, evidenced through the obtained results the justness of the selection for: the raw materials (100% cotton, cotton/PES, 100% PES), the weave (plain, twill, rib, pique), the fabric tightness and fabric cover etc. These data allowed the elaboration of textile material’s specifications for impact plates.
