An antibacterial and flame retardant yarn and a production process thereof, the yarn comprises: a core layer and a surface layer covering the outer wall of the core layer, the core layer is formed by intertwisting an antibacterial strand and a flame retardant strand, and the surface layer comprises The antibacterial coating, the heat insulating fiber layer and the flame retardant coating are sequentially arranged on the surface of the core layer from the inside to the outside; the antibacterial strands are formed by blending nano-titanium dioxide catalyst fibers and bamboo charcoal fibers; the flame retardant strands are composed of PPT fibers and Formed by blending teflon fibers. The yarn is formed by intertwisting antibacterial strands and flame-retardant strands, and the antibacterial strands are formed by blending nano-titanium dioxide catalyst fibers and bamboo charcoal fibers with the antibacterial strands; the flame-retardant strands are formed by blending PPT fibers and polytetrafluoroethylene fibers. , the composite of various fibers, and the antibacterial coating, the thermal insulation fiber layer and the flame retardant coating arranged on the surface layer, so that the yarn has better antibacterial and flame retardant effects, and the yarn preparation cost is low and economical The benefits are good, which is conducive to large-scale production.
