Problems solved by technology

Chinese patent 200480034895 announced the use of antibacterial agent-treated fibers, which proposed the use of formaldehyde, dimethylol or dihydroxyethyl urea, and melamine prepolymers as self-crosslinking resins to modify the fiber surface. Non-cellulosic fibers such as polyester, polyamide, polyurethane, and cellulose acetate are loaded with quaternary ammonium antibacterial agents as a composition to inhibit microbial growth to prepare antibacterial fibers and fabrics; this method modifies the surface of the fibers It is not suitable for polypropylene fibers with high inertness, natural plant fibers with strong water absorption and chitin fibers

Chinese patent 200610101336 discloses the fiber containing the antibacterial composition, through the coordination polymer containing coordination group and crosslinkable, the nanoparticle antibacterial composition component of copper, silver, gold, tin, zinc and its combination Covered on fibers and fabrics to achieve antibacterial and antibacterial effects; Chinese patent 200610122059 discloses a preparation method for nano-antibacterial fabrics, using high molecular polymers as dispersants and auxiliary binders, and metal ions as antibacterial factors. Use nitrogen azole organic compounds as the anchoring agent of metal ions on the fabric fibers, and combine with metal ions to form nanoparticles on the fibers, so that the fabrics have excellent antibacterial and deodorizing functions; the above schemes, for different types of Whether the fiber can effectively cross-link with the cross-linkable coordination polymer and the degree of cross-linking is very different; if the amount of cross-linkable coordination polymer added is small, microscopically, the antibacterial There is uneven distribution of components in fibers and fabrics; if the added amount is large or the molecular weight of the cross-linkable coordination polymer is large, it will seriously affect the air permeability of the fabric; and for fibers and fabrics with weak cross-linking ability During the washing process of fibers and fabrics after cross-linking treatment, a large number of uncross-linked coordination prepolymers will be eluted and affect the loading capacity of antibacterial components
