Coatings with recycled polyvinyl butyral on polyester and polyamide mono- and multifilament yarns

Abstract Polyvinyl butyral is used in safety glass interlayers, mainly car windshields. Legislative regulations require a recycling of cars after their lifetime and therefore also glass. This causes the availability recycled polyvinyl butyrate (r-PVB) originated from interlayers. Due to deteriorated optical properties, such as transparency, unknown amounts plasticizers, it challenging reuse material new Therefore, particular interest find fields application for r-PVB, usage textile coating. In this research, r-PVB was investigated yarn Polyester polyamide mono- multifilament yarns were coated continuously with solely polymer dispersion mixtures crosslinking agent dispersion. Crosslinked coatings showed enhanced properties toward abrasion chemical resistance. Coatings without diminished resistance could be washed off ethanol. Mechanical monofilaments influenced by coating general. However, varying concentrations did not affect mechanical properties.
