AI Technical Summary
In existing technologies, the antibacterial layer of antibacterial textiles is easily worn away and washed off, resulting in poor durability. When inorganic antibacterial agents are added during melt spinning, the fiber strength decreases, and the antibacterial agents are difficult to effectively migrate to the surface to exert their effects. Air-jet spinning technology makes it difficult to achieve stable, uniform dispersion and surface exposure of antibacterial materials.
Long-lasting antibacterial textile fabrics are prepared by using a polymer matrix and guanidine-metal@silica aerogel composite fibers through an air-jet spinning process. The porous carrier characteristics of aerogel and the synergistic antibacterial mechanism of guanidine and metal ions are utilized. The in-situ spinning process stably loads antibacterial functional units, and combines the cross-linking and curing effect of aerogel carrier and antibacterial components.
It achieves comprehensive optimization of antibacterial properties, significantly prolongs the antibacterial effect, and maintains the mechanical and processing properties of the fiber, making it suitable for high-end scenarios such as medical, sports, and infant care.
