Technical Field

[0002] With the development of the economy, people's dressing concept has changed. The demand for clothes is no longer simply the pursuit of their appearance and durability, but the hope that the clothes they wear have better comfort. The comfort of clothing is coordinated and acted upon by a variety of environmental factors, people's natural activity state and the characteristics of the clothing itself. The comfort of fabrics is divided into several different aspects, including psychological comfort, pressure comfort, physiological comfort, and thermal and moist comfort. They have different focuses but complement each other. In the process of studying comfort, thermal and moist comfort is a crucial part. A microenvironment of heat and moisture transfer can be generated between people and the environment. In this microenvironment, fabrics can maintain the body temperature balance of the human body, provide the human body with a good thermal and moist condition, ensure the normal and stable physiological functions of the human body, and maintain the human body's comfort.

When people exercise, they will inevitably have the trouble of hot and sweating, and clothes are prone to breed bacteria after being stained with sweat. Therefore, the present invention prepares a moisture-conducting and cool fabric for sportswear with excellent antibacterial properties. Summary of the invention

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when preparing the moisture-conducting and cooling fabric for sportswear, the porous nano-alumina is loaded with zinc ions and then grafted with chloromethyltrimethoxysilane, and then reacted with 2,6-pyridine dimethanol and 3,6-dichloro-4-vinylpyridazine to obtain modified zinc-loaded nano-alumina; diethyl (formylmethyl) phosphate is reacted with 4-methylpyridine to obtain a modified monomer; dimethyl terephthalate, the modified monomer and ethylene glycol are reacted to obtain a modified polyester slice; the modified polyester slice, the modified zinc-loaded nano-alumina and polyethylene glycol 2000 are mixed and spun to obtain spun fibers; the spun fibers are reacted with hydrogen-containing silicone oil to obtain a precursor fabric, and then reacted with 3-bromopropyltrimethylammonium bromide to obtain a moisture-conducting and cooling fabric.

[0020] First, porous nano-alumina is loaded with zinc ions and then grafted with chloromethyltrimethoxysilane, and then reacted with 2,6-pyridine dimethanol and 3,6-dichloro-4-vinylpyridazine to obtain modified zinc-loaded nano-alumina; diethyl (formylmethyl) phosphate is reacted with 4-methylpyridine to obtain a modified monomer; dimethyl terephthalate, the modified monomer and ethylene glycol are then reacted to obtain a modified polyester slice; porous nano-alumina with high thermal conductivity is used as a reinforcing phase to enhance the thermal conductivity of the moisture-conducting and cool fabric and strengthen the cool effect; zinc ions are then loaded in the pores, and the zinc ions are used to interact with the negative ions of bacterial cells to cause abnormal enzyme and protein mechanisms in the bacterial cells, destroy cell metabolism, and improve the antibacterial property of the moisture-conducting and cool fabric ; 2,6-pyridine dimethanol and 3,6-dichloro-4-vinylpyridazine are polymerized and grafted on the surface of porous nano-alumina. The pyridine ring can complex zinc ions to achieve a sustained release effect, thereby improving the long-lasting antibacterial properties of the moisture-conducting and cool fabric. During the combustion process, the pyridazine ring can produce nitrides, nitrogen-containing free radicals and other substances, which react with the free radicals in the combustion process to inhibit the continuation of the combustion reaction and improve the flame retardant properties of the moisture-conducting and cool fabric. A modified monomer containing a carbon-carbon double bond is obtained by condensing methyl and formaldehyde under the catalysis of pyridine, participating in the polymerization of the polyester main chain, introducing phosphorus, and reacting with the free radicals generated during the combustion process to form a stable carbon layer, blocking oxygen, inhibiting the spread of flames, and further improving the flame retardant properties of the moisture-conducting and cool fabric.

[0021] Secondly, the modified polyester chips, modified zinc-loaded nano-alumina and polyethylene glycol 2000 are mixed and spun to obtain spun fibers; the spun fibers are reacted with hydrogen-containing silicone oil to obtain a precursor fabric, which is then reacted with 3-bromopropyltrimethylammonium bromide to obtain a moisture-conducting and cool fabric; polyethylene glycol 2000 is used as a porogen to form a pore structure to improve the moisture-conducting and cool fabric; the spun fibers are post-finished with hydrogen-containing silicone oil, and the modified polyester chips and the modified zinc-loaded nano-alumina are reacted with the hydrogenated silicone oil by a silylation reaction. The carbon-carbon double bonds react to form a cross-linked network, which improves the mechanical properties of the moisture-conducting and cool fabric. The finishing with hydrogen silicone oil also enhances the hydrophobic ability of the fiber. After the fabric is woven, it is single-sided finished with 3-bromopropyltrimethylammonium bromide, and the trimethylammonium bromide ion is used as the hydrophilic end to form a unidirectional moisture-conducting structure with a hydrophobic inner layer and a hydrophilic outer layer, further improving the moisture-conducting and cool fabric. At the same time, nitrogen heterocyclic quaternary ammonium salts are formed to increase the positive charge density, enhance the antibacterial activity, and further improve the antibacterial properties of the moisture-conducting and cool fabric.
