step S2, preparation of copolymer fiber: uniformly mixing the barbaloin D/N- [4- (sulfamide) phenyl ] acrylamide/(Z) -2- (2-aminothiazole-4-yl) -2-pentenoic acid/adenine copolymer and 2,4, 6-tri (ethylene oxide-2-ylmethoxy) -1,3, 5-triazine which are prepared by the step S1 according to a proportion to obtain a mixture, then extruding, blending and melting the mixture by a screw machine, and spinning and molding the melt by a special-shaped hole spinneret plate to obtain copolymer fibers;
step S3, knitting: weaving by using a circular knitting machine, adopting a single-side plating weave, setting by using the circular knitting machine, and carrying out one-over-one weaving, wherein a base material layer of the fabric is the copolymer fiber prepared in the step S2, a surface layer of the fabric is the quaternary ammonium salt chitosan fiber, and obtaining grey cloth after weaving;
step S4, finishing: and (5) the grey cloth manufactured in the step S3 is sequentially subjected to ironing, dyeing, pre-setting, upper soft dehydration, drying, finished product ironing, tentering and setting to obtain the finished product.
2. The bacteriostatic and mildewproof fabric of claim 1, wherein the mass ratio of the barbaloin D, N- [4- (sulfonamide) phenyl ] acrylamide, (Z) -2- (2-aminothiazole-4-yl) -2-pentenoic acid, the enadenine, the initiator and the high-boiling-point solvent is 1:2:1:0.5 (0.03-0.05) to (12-20).
3. A bacteriostatic and mildewproof fabric according to claim 1, wherein the initiator is at least one of azobisisobutyronitrile and azobisisoheptonitrile.
4. An antibacterial and mildewproof fabric according to claim 1, wherein the high-boiling-point solvent is at least one of dimethyl sulfoxide, N-dimethylformamide and N, N-dimethylacetamide.
5. A bacteriostatic and mildewproof fabric according to claim 1, wherein the inert gas is one of helium, neon and argon.
6. An antibacterial and mildewproof fabric according to claim 1, wherein the mass ratio of the barbaloin D/N- [4- (sulfonamide) phenyl ] acrylamide/(Z) -2- (2-aminothiazole-4-yl) -2-pentenoic acid/enamine purine copolymer to the 2,4, 6-tris (ethylene oxide-2-ylmethoxy) -1,3, 5-triazine in the step S2 is 1 (0.1-0.2).
7. The bacteriostatic and mildewproof fabric as claimed in claim 1, wherein the spinning temperature is 250-300 ℃ and the spinning speed is 2500-3500 m/min.
