“…Depositing a PTFE coating on a PP yarn makes it possible to carry out its orientational drawing at higher temperatures than those used for a standard PP yarn. This makes the yarn strength parameters better [25,26]. However, it is necessary to find out how doping the PTFE coating with magnetite particles, namely the size of these particles, affects the yarn strength.…”

“…[20][21][22]. We had earlier proposed a fundamentally new approach to obtaining PP yarns with a polytetrafluoroethylene (PTFE) coating [23][24][25]. According to this approach, PTFE adhesion to the surface of a thermoplastic yarn is achieved by depositing a suspension of finely dispersed PTFE on the surface of a semi-solidified yarn at the stage of its formation on the polymer (oiling stage).…”

This paper describes an original method for forming a stable coating on a polypropylene yarn. The use of this method provides this yarn with barrier antimicrobial properties, reducing its electrical resistance, increasing its strength, and achieving extremely high chemical resistance, similar to that of fluoropolymer yarns. The method is applied at the melt-spinning stage of polypropylene yarns. It is based on forming an ultrathin, continuous, and uniform coating on the surface of each of the yarn filaments. The coating is formed from polytetrafluoroethylene doped with magnetite nanoparticles stabilized with sodium stearate. The paper presents the results of a study of the effects of such an ultrathin polytetrafluoroethylene coating containing stabilized magnetite particles on the mechanical and electrophysical characteristics of the polypropylene yarn and its barrier antimicrobial properties. It also evaluates the chemical resistance of the polypropylene yarn with a coating based on polytetrafluoroethylene doped with magnetite nanoparticles.

“…Recently, a method has been developed to impart antimicrobial properties to polypropylene thread by embedding iron oxide nanoparticles in a coating based on polytetrafluoroethylene [124,125]. The coating is formed on the surface of the thread at the stage of its molding from the melt [126]. The coating with embedded iron oxide nanoparticles is resistant to dry friction, washing, and the action of chemically aggressive liquids [124,125].…”

This review summarizes the results of research published in recent decades on the main directions in the functionalization of fibrous materials using surface modification. Methods for thepreliminary activation of the surface of fibrous materials are described, allowing increasing the adhesion of modifiers. The features of the formation of functionalizing coatings on fibrous materials in comparison with other substrates are analyzed. Some specific methods for evaluating the effectiveness of the surface modification inherent in fibrous materials are considered. Particular attention is paid to giving fibrous materials antimicrobial properties, photoactivity, the ability to protect against ultraviolet radiation, and hydrophobicity.
