The preparation method of the epoxy polyurethane emulsion comprises the steps of mixing 35-50 parts of isophorone diisocyanate and 100 parts of polyethylene glycol 1000 according to parts by weight, reacting for 1-2 hours at 50-60 ℃ by taking dibutyl tin dilaurate as a catalyst, adding 6-8 parts of dimethylolpropionic acid to react for 0.5-1 hour, adding 5-7 parts of 1, 4-butanediol to react for 1-2 hours to obtain an isocyanate-terminated polyurethane prepolymer, adding glycidol according to the mol ratio of isocyanate groups to hydroxyl groups of 1:1 to react for 1-2 hours, cooling, adding 9-13 parts of triethylamine to neutralize, and adding deionized water to emulsify to obtain the epoxy polyurethane emulsion with the solid content of 30-40%.
Further, the preparation method of the epoxy-based flame retardant comprises the following steps:
S1, dispersing eugenol in ethyl acetate, cooling in an ice bath until the system temperature is stable by taking triethylamine as an acid binding agent, adding phenyl dichlorophosphate, stirring for 24 hours at 20-30 ℃, and finally separating, washing and rotary steaming the product to obtain phenyl di-eugenol phosphate;

Further, in S1, eugenol and phenyl dichlorophosphate are reacted according to a molar ratio of 2:1.
Further, in S2, phenyl diglucoside and m-chloroperoxybenzoic acid react according to a molar ratio of 1:2.
The preparation method of the epoxy organosilicon quaternary ammonium salt comprises the steps of dispersing N, N-diethyl amine propyl methyl dimethoxy silane in absolute methanol under a nitrogen environment, heating to 55-65 ℃, adding a mixed solution of epichlorohydrin and absolute methanol, after the addition is finished, carrying out heat preservation reaction for 6-10 hours, carrying out rotary evaporation to remove the absolute methanol, eluting with absolute ethyl ether, and carrying out vacuum drying to obtain the epoxy organosilicon quaternary ammonium salt.
Further, N, N-diethyl amine propyl methyl dimethoxy silane and epoxy chloropropane are reacted according to the mol ratio of 1:1.
Further, in the environment-friendly breathable polyester yarn fabric, 15-20% of bio-based spinning fibers and 80-85% of modified polyester yarn are blended according to weight percentage.
Compared with the prior art, the polyester yarn fabric has the beneficial effects that the polyester yarn fabric prepared by the method has good flame retardant property, antibacterial property and air permeability, wherein part of the polyester yarn fabric is made of renewable environment-friendly materials, so that the preparation cost can be reduced, and the environment-friendly development requirement can be met.
The invention uses the modifier to modify the polyester yarn. The main components of the modifier include capping polyurethane prepolymer with glycidol as capping agent to obtain epoxy polyurethane emulsion, reacting eugenol with phenyl dichlorophosphate to obtain phenyl di-eugenol phosphate, epoxidizing double bonds at two ends of the phenyl di-eugenol phosphate with m-chloroperoxybenzoic acid as oxidant to obtain epoxy flame retardant, and reacting N, N-diethyl amine propyl methyl dimethoxy silane and epichlorohydrin as raw materials to obtain epoxy organosilicon quaternary ammonium salt. The main components contain epoxy groups, and a film layer can be formed on the surface of the polyester yarn after the epoxy groups are added and cured under the action of an amine curing agent, wherein the epoxy group flame retardant provides a certain flame retardant property, and the epoxy group organosilicon quaternary ammonium salt can not only enhance the antibacterial property of the surface of the polyester yarn, but also be an organosilicon cationic surfactant for application, and has the solubilization and emulsification effects on the modifier.
The invention blends polyester yarn and bio-based spinning fiber to prepare fabric, wherein the bio-based spinning fiber is obtained by mixing carboxymethyl cellulose solution and chitosan solution and then carrying out electrostatic spinning technology. In the bio-based spinning fiber, chitosan has good antibacterial performance, and the chitosan and the epoxy-based organosilicon quaternary ammonium salt in the modifier improve the antibacterial effect and the antibacterial durability together. The carboxymethyl cellulose and the chitosan are porous structure materials, so that the porous structure material has higher porosity and can improve the air permeability of the fabric. In addition, in the practical research and development process, the inventor surprisingly found that compared with the polyester yarn fabric modified by the modifier, the polyester yarn fabric disclosed by the invention has better flame retardant property, and through repeated researches, the inventor believes that the polyester yarn fabric mainly benefits from the existence of chitosan in the bio-based spinning fiber, the chitosan contains a large amount of amino groups, and the polyurethane coating on the surface of the modified polyester yarn is decomposed to generate isocyanate groups in the combustion process, and can react with the amino groups in the chitosan, so that the concentration of combustible substances is reduced, the combustion process is inhibited, and the flame retardant effect is further improved. It should be noted that the higher the amount of the bio-based spun fiber is, the better the amount is, and the higher the amount is, the crease resistance and rebound resilience of the fabric are reduced, so that the amount of the bio-based spun fiber and the modified polyester fiber is controlled during blending, specifically, 15-20% of the bio-based spun fiber and 80-85% of the modified polyester fiber are calculated according to weight percentages.
