Waste problem on plastic relates to micro plastic issue and synthetic textile fibers pronounce part of the problem. Inherently the problems in recycling are rising form the structure of the textiles, comprising of textile fiber blends, yarn and garment structures and well the components typical for clothing. In chemical separation methods, the sensitivity of both of the polymers defines strict limits to which conditions are possible without depolymerizing or damaging markedly either of the main components. In this paper we discuss the challange of available processes.
