Antibacterial nylon is disclosed. The antibacterial nylon includes nylon resin and an antibacterial agent dispersed in the resin. The antibacterial agent is attapulgite-nanometer silver composite inorganic powder, wherein the mass ratio of the nanometer silver to the attapulgite is 10/100-100/100, and the particle diameter range of the nanometer silver is 3-100 nm. The antibacterial agent has advantages of a low using amount, a low cost, a simple preparing process, capability of improving mechanical performance, and the like, can improve antibacterial performance of materials, can increase material rigidity with a small using amount, and is an ideal nylon resin modifying auxiliary agent.
