Silvering of inert polyethylene terephthalate textile materials: The factors of adjustment on silver release, part II

Abstract

The aim of this research is to develop a textile product to prevent and eliminate biological contaminations in drinking water and other liquid-leading systems. Herein, the adjustment of the silver release from silvered textile materials with the retention of the antibactericidal qualities has been studied. The limited values for silver in drinking water in Germany (100 µg/l) must be considered as well. Moreover, the factors of the adjustment of the silver release, such as the concentration of the silver on the one hand and the reduction agent, the silvering process, the thermal fixation time and temperature, the size of the silver particles, and the thickness of the silver layer on the surface of textile materials for the silvering on the other hand have been systematically examined by using polyethylene terephthalate (PET) materials as a basis. Silver concentration in the elution has been detected by means of atom absorption spectroscopy (ZEEnit 700, Analytics Jena, Germany). The amount of silver taken up by PET was weighed after was under a constant heat of 900°C for 4 h.

Bifunctionalization of cotton textiles by ZnO nanostructures: antimicrobial activity and ultraviolet protection

“…In this method, metal ions are initially adsorbed onto fiber surfaces by electrostatic or Van der Waals forces and then post-treated with reduction treatment, to reduce metal ions into nanoparticles. By taking advantages of this method, various metal nanoparticles, including Au, 2 Ag, 19,42,43 ZnO 35 and CuO, 10 were successfully synthesized on fibers/fabrics.…”

Antimicrobial Treatment of Polyurethane Membrane Using Photodeposition of Nano-titanium Dioxide and Nano-silver

“…Lim 등 [21]은 광촉매 환원법으로 전기방사 나노섬유에 도입하는 것에 관해 보고한 바 있다. 또한 Ag의 단독 사용 뿐만 아니라 제올라이트 등에 함침 된 형태 [23][24][25][26][27]도 직물에 적용되고 있다. 은-제올라이트의 조합은 금속으로서의 은 원자 단독 사용시보다 더 뛰어난 향균성을 나타내고 열적 안전성도 훌륭하다 [28].…”

Electroless silver coating on glass stitched fabrics for electromagnetic shielding applications

“…14,18,20 A number of methods are available for the preparation of metal nanoparticles, including condensation in the vapor phase, chemical reduction in solution, photoreduction, ultrasound-induced reduction, chemical vapor deposition, sol-gel methods, and electroless deposition. 15,21,22,23 The electroless deposition of metals from solution is often encountered industrially since it provides a uniform metal layer, even on materials of complex shape. 24 EMI SE values up to 45 dB have been obtained on PES fabrics coated by this method within the frequency range 300-1500 MHz.…”
