The aim of the research was the solvent-based impregnation of poly(lactic acid) (PLA) withThe present work developed a new and simple method for producing engineered nylon yarns by two-step coating. The nylon yarns were first immersed in a solution containing a silane coupling agent (3-Aminopropyltriethoxysilane) to improve the adhesion properties. Then the modified samples were heat-treated in a solution containing cupric nitrate, hydroxylamine sulfate, and sodium pyrosulfite. Microstructural imaging of the coated surfaces shows a homogeneously formed coating layer without any microscopic cracks or discontinuity in the sample surface. Results showed that this two-step coating can produce nylon yarns with good electrical conductivity and anti-microbial properties. The coated samples displayed very good light fastness and washing fastness to multiple washes in terms of electrical conductivity changes and anti-microbial activity.

W ramach badań opracowano nową i prostą metodę wytwarzania specjalnych przędz nylonowych poprzez powlekanie dwuetapowe. W celu poprawy właściwości adhezyjnych przędze nylonowe zanurzono w roztworze zawierającym silanowy środek sprzęgający (3-aminopropylotrietoksysilan). Następnie zmodyfikowane próbki poddano obróbce cieplnej w roztworze zawierającym azotan miedzi, siarczan hydroksyloaminy i pirosiarczyn sodu. Obrazowanie mikrostrukturalne powlekanych powierzchni pokazało jednorodnie utworzoną warstwę powłokową bez mikroskopijnych pęknięć lub nieciągłości na powierzchni próbki. Wyniki wykazały, że ta dwustopniowa powłoka może wytwarzać przędzę nylonową o dobrej przewodności elektrycznej i właściwościach przeciwdrobnoustrojowych. Pokryte próbki wykazywały bardzo dobrą odporność na światło i odporność na wielokrotne pranie pod względem zmian przewodności elektrycznej i aktywności przeciwdrobnoustrojowej.
