Study Data from S. Vilchez-Maldonado et al Provide New Insights into Nanoparticles (UV protective textiles by the deposition of functional ethylcellulose nanoparticles)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Nanoparticles. According to news reporting from Barcelona, Spain, by NewsRx journalists, research stated, "Ethylcellulose (EC) nanoparticles have been widely investigated for their use as drug delivery systems. However, their application on the textile field has been hardly studied."

The news correspondents obtained a quote from the research, "In this work, the use of EC nanoparticles as nanocarriers of active or lipid soluble compounds and their subsequent deposition on cotton textile is proposed in order to obtain functional textiles. A UV protective textile has been obtained after deposition of EC nanoparticles loaded with a liposoluble UV filter on cotton fabrics. The EC/cotton affinity and the attachment mechanism of EC nanoparticles on cotton substrate was studied by means of thermal behaviour evaluation, estimation of adhesion work (W-A) and wash resistance tests. It is proposed that during EC nanoparticles deposition on cotton fabric, entanglement of polymeric chains is favoured, thus improving adhesion of EC nanoparticles on cotton substrate. The functionality of cotton textile was assessed by ultraviolet protection factor (UPF) measurements, showing a high UPF value (UPF = 45). Evaluation of UPF as a function of washing cycles were carried out on treated cotton fabrics."

According to the news reporters, the research concluded: "Washed fabrics still provided good UV protection (UPF a parts per thousand yen 25), evidencing the presence of nanoparticles after washing cycles and the durability of the conferred functionality."
