Abstract

The antibacterial viscose rayon, according to the invention, is used for the manufacture of any type of textile articles, including items intended for medical use, ensuring a more lasting antibacterial and antifungal protection due to the uniform distribution of the antibacterial additive throughout the entire volume of the fibre. According to the invention, immediately before spinning, the viscose is mixed and homogenized with an antibacterial additive, and then spun following the classical procedure: the viscose solution, with required and strictly specified parameters is fed under pressure to the spinnerets of the spinning machine from which the cellulose solution enters a spin bath, where as a result of the chemical reactions in course is transformed into fibres subjected afterwards to a subsequent treatment. According to the invention, in the production of dope dyed antibacterial rayon, into the preliminarily prepared suspension composed of one or a couple of pigments, a specified amount of antibacterial additive is introduced, the obtained mix is homogenized and filtered, and then subjected to the classical stages of spinning and subsequent treatments.
