Abstract：
 The preparation method of macromolecular sterilization fibre whose surface is grafted by antibacterial monomer belongs to the field of sewage treatment technology, and includes the following steps: firstly, adding quaternary ammonium salt, halogenated amine and macromolecular fibre in the reactor, then adding reaction solvent, charging nitrogen gas into the reactor and discharging air, adding initiating agent to make reaction, after reaction using lots of solvent to stir and flush, filtering and drying, extracting the grafted collulose fibre by using aqueous solution of acetone, and soaking the grafted cellulose fibre in sodium hypochlorite, taking out fibre and drying at room temp. Said invention macromolecular sterilization fibre is a macromolecular treatment agent, not only can be used for treating water, but also can be used as medical gauze, artificial skin and shell fabric.
