Medium-free method for preparing antibacterial textile and prepared textile

The invention provides a method for preparing an antibacterial textile without a medium and the prepared textile, the method comprises the following steps: A, diallylamine and a second monomer are sequentially added to prepare a spraying liquid, the addition amount of diallylamine is 20.0-70.0% of the mass fraction of a comonomer, the second monomer is N, N-diethylacrylamide or N, N-diethylacrylamide, the addition amount of diallylamine is 20.0-70.0% of the mass fraction of the comonomer, and the second monomer is N, N-diethylacrylamide or N, N-diethylacrylamide or N, N-diethylacrylamide or N, N-diethylacrylamide; n, N-dimethylacrylamide is one or a mixture of two of acrylamide and N, N-dimethylacrylamide; b, spraying; c, irradiating; d, extracting; and E, halogenating. According to the textile with the antibacterial function, the fiber fabric serves as a textile and also serves as a carrier support of antibacterial functional compounds such as bacteriostasis and sterilization, when people use the textile, th
