Flame-retardant antibacterial skin-friendly functional lyocell fiber and preparation method thereof

Flame-retardant, antibacterial, and skin-friendly functional lyocell fibers were prepared by combining microencapsulated melamine phosphate with amino acid crosslinked phytic acid solution. This solved the problem of insufficient flame retardancy and antibacterial properties of lyocell fibers, achieving long-lasting flame-retardant and antibacterial effects as well as good skin-friendly properties, making it suitable for intimate home and medical textiles.
