A washable antibacterial nylon fabric and a preparation method thereof
By introducing N-hydroxymethyl groups onto the surface of nylon fabrics and forming an antibacterial film through interfacial polymerization of PEI and TMC, and combining the amino reduction and coordination effects of PEI to achieve in-situ deposition of nano-silver, the problems of weak binding force and poor washability of antibacterial agents on nylon fabrics are solved, thereby improving the antibacterial durability and breathability of nylon fabrics.

AI Technical Summary
Existing antibacterial finishing technologies for nylon fabrics suffer from weak binding force of antibacterial agents, poor washability, and difficulty in effectively loading nano-silver, which affects the breathability and hand feel of the fabric and cannot meet the long-term antibacterial requirements.
A two-bath stepwise process was adopted, in which N-hydroxymethyl groups were introduced on the surface of nylon fibers through formaldehyde activation treatment, and an antibacterial film was formed by interfacial polymerization of polyethyleneimine (PEI) and trimesoyl chloride (TMC). In-situ deposition of nano-silver was achieved by means of amino reduction and coordination of PEI.
This invention achieves highly washable antibacterial nylon fabric with long-lasting antibacterial effect and photodynamic antibacterial efficacy, while maintaining the fabric's hand feel and breathability, and improving the binding strength and washability of the antibacterial agent.
