[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] When preparing the mildew-proof quick-drying towel fabric, the present invention firstly reacts p-hydroxybenzaldehyde and cyanuric chloride to obtain a prepolymer, then reacts the prepolymer, 4,4'-diamino-2,2'-bipyridine and 4,4'-diaminostilbene to obtain a conjugated porous polymer, then reacts with ferric chloride, 4-hydroxypyridine and 2,2-dihydroxymethylpropionic acid in sequence to obtain a pre-modified conjugated porous polymer, finally reacts with 10-undecenylamine and iodomethane to obtain a modified conjugated porous polymer, electrospins polypropylene alcohol, the modified conjugated porous polymer and the modified copolymer into fibers, and weaves the fibers to obtain the mildew-proof quick-drying towel fabric.

[0022] First, 4-hydroxypyridine and the conjugated porous polymer form a conjugated metal coordination connection under the action of iron ions, and then react with 2,2-dihydroxymethylpropionic acid to branch and grow in the pores of the conjugated porous polymer to form terminal hydroxyl dendritic polyester. The conjugated porous polymer can convert light into electron migration, and the electron migration generates heat. The terminal hydroxyl dendritic polyester in the pores of the modified conjugated porous polymer forms a conduction channel for water molecules. The conjugated metal coordination connection improves the conduction of heat and conducts the heat to the conduction channel of adjacent water molecules, accelerating the conduction of water molecules, thereby improving the quick-drying property; the pre-modified conjugated porous polymer reacts with 10-undecenylamine and then reacts with iodomethane to form long-chain quaternary ammonium salt branches on the outside of the modified conjugated porous polymer. The long-chain quaternary ammonium salt branches are hydrolyzed into quaternary ammonium cations, which pierce the bacteria with their fat-soluble long carbon chains, eventually causing the bacteria to be inactivated, thereby improving the mildew resistance.

[0023] Secondly, p-aminostyrene and propylene are reacted to obtain a copolymer, which is then reacted with 1,2,4,5-tetrakis(4-carboxyphenyl)benzene to obtain a modified copolymer. The introduction of 1,2,4,5-tetrakis(4-carboxyphenyl)benzene increases the overall conjugated structure, improves the light-heat conversion conduction effect, and improves the quick-drying property. Secondly, the 1,2,4,5-tetrakis(4-carboxyphenyl)benzene side chains on the modified copolymer are hydrolyzed to form carboxyl anions, and the long-chain quaternary ammonium salt side chains on the modified conjugated porous polymer are hydrolyzed to form quaternary ammonium cations. The carboxyl anions and quaternary ammonium cations can be combined through electrostatic forces to reduce the loss and damage of the quaternary ammonium cations, thereby improving the antibacterial durability of the mildew-proof and quick-drying towel fabric.

[0062] Effect example

[0063] Table 1 below shows the performance analysis results of the mildew resistance, quick-drying property, and antibacterial durability of the mildew-proof and quick-drying towel fabrics of Examples 1 to 3 of the present invention and Comparative Examples 1 to 6.

[0064] Table 1

[0065] Antibacterial rate Drying time Retention rate Antibacterial rate Drying time Retention rate Example 1 99.3％ 43min 96.1％ Comparative Example 3 99.0％ 57min 81.2％ Example 2 99.5％ 40min 96.2％ Comparative Example 4 99.0％ 55min 89.5％ Example 3 99.6％ 45min 95.8％ Comparative Example 5 67.3％ 89min 96.3％ Comparative Example 1 99.1％ 72min 95.7％ Comparative Example 6 98.6％ 60min 80.3％ Comparative Example 2 84.7％ 43min 95.3％

[0066] From the comparison of the experimental data of Examples 1 to 3 and Comparative Examples 1 to 6 in Table 1, it can be found that the mildew-proof and quick-drying towel fabric prepared by the present invention has good mildew resistance, quick drying, and antibacterial durability.

[0067] From the comparison of the experimental data of Examples 1, 2, and 3 and Comparative Example 1, it can be found that the drying time of Examples 1, 2, and 3 is shorter than that of Comparative Example 1, which indicates that in the process of preparing the pre-modified conjugated porous polymer, 4-hydroxypyridine and the conjugated porous polymer form a conjugated metal coordination connection under the action of iron ions, and then react with 2,2-dihydroxymethylpropionic acid to branch and grow in the pores of the conjugated porous polymer to form a terminal hydroxyl branched polyester. The conjugated porous polymer can convert light into electron migration, which generates heat. The terminal hydroxyl branched polyester in the pores of the modified conjugated porous polymer forms a conduction channel for water molecules. The conjugated metal coordination connection improves the conduction of heat and conducts the heat to the conduction channels of adjacent water molecules, accelerating the water The conduction of molecules improves the quick-drying property of the mildew-proof quick-drying towel fabric; from the comparison of the experimental data of Examples 1, 2, 3 and Comparative Example 2, it can be found that the antibacterial rate of Examples 1, 2, and 3 is higher than that of Comparative Example 2, which shows that the pre-modified conjugated porous polymer reacts with 10-undecenylamine and then with iodomethane to obtain a modified conjugated porous polymer, and a long-chain quaternary ammonium salt branch is formed on the outside of the modified conjugated porous polymer. The long-chain quaternary ammonium salt branch is hydrolyzed into a quaternary ammonium cation, which pierces the bacteria with its fat-soluble long carbon chain, and finally causes the bacteria to be inactivated, thereby improving the mildew resistance of the mildew-proof quick-drying towel fabric; from the comparison of the experimental data of Examples 1, 2, 3 and Comparative Example 3, it can be found that the drying time of Examples 1, 2, and 3 is short compared with Comparative Example 3, and the durability rate is High, indicating that the copolymer prepared by the reaction of p-aminostyrene and propylene is reacted with an excess of 1,2,4,5-tetrakis(4-carboxyphenyl)benzene to obtain a modified copolymer. The introduction of 1,2,4,5-tetrakis(4-carboxyphenyl)benzene increases the overall conjugated structure, improves the light-heat conversion conduction effect, and improves the quick-drying property of the mildew-proof quick-drying towel fabric. Secondly, the 1,2,4,5-tetrakis(4-carboxyphenyl)benzene side chains on the modified copolymer are hydrolyzed to form carboxyl anions, and the long-chain quaternary ammonium salt side chains on the modified conjugated porous polymer are hydrolyzed to form quaternary ammonium cations. The carboxyl anions and quaternary ammonium cations can be combined by electrostatic force to reduce the loss and damage of the quaternary ammonium cations, thereby improving the antibacterial durability of the mildew-proof quick-drying towel fabric. ; From the comparison of the experimental data of Examples 1, 2, 3 and Comparative Example 4, it can be found that the drying time of Examples 1, 2, 3 is shorter than that of Comparative Example 4, and the durability is high, which shows that the use of 1,2,4,5-tetrakis(4-carboxyphenyl)benzene to modify the copolymer forms a relatively large 1,2,4,5-tetrakis(4-carboxyphenyl)benzene rigid closed branch on the copolymer side chain compared to the use of butanetetracarboxylic acid to modify the copolymer, and has a better protective effect on the long-chain quaternary ammonium salt branch on the modified conjugated porous polymer than butanetetracarboxylic acid, thereby improving the antibacterial durability of the mildew-proof quick-drying towel fabric. At the same time, water molecules control the opening and closing of the rigid closed branch chains, and the conjugated structure of the rigid closed branch chains can promote heat conduction, thereby improving the quick-drying property of the mildew-proof quick-drying towel fabric.
