Abstract
The invention discloses a preparation method of an anti-mosquito fabric, and relates to the technical field of textile materials. When the anti-mosquito fabric is prepared, firstly, hollow porous polyester with 1, 12-dodecanediamine inside is prepared, then 1, 12-dodecanediamine is used for internal aminolysis, free amino is formed by methyl iodide to form quaternarization to prepare quaternary ammonium polyester fiber, then the quaternary ammonium polyester fiber is immersed into a titanyl sulfate solution to deposit nano titanium dioxide inside the quaternary ammonium polyester fiber, pyrrole diester is polymerized and deposited to form polypyrrole diester through primary catalysis, and the polypyrrole diester is hydrolyzed to produce hydroxyl and hole-forming and then woven through secondary catalysis to prepare the anti-mosquito fabric. The anti-mosquito fabric prepared by the invention has good anti-mosquito effect and is durable and effective.
Description
Technical Field
The invention relates to the technical field of textile materials, in particular to a preparation method of an anti-mosquito fabric.
Background
In summer, people's daily activities are often severely affected by mosquitoes. Because the mosquito net has no mosquito-repellent function, the mosquito flies into the mosquito net to bite the human body at night when sleeping, so that the human cannot fall asleep; because the clothes have no mosquito repelling function, the human body can be continuously bitten by mosquitoes, and the work and the life of the human body are seriously affected. In addition, mosquitoes can transmit diseases, and different kinds of mosquitoes can transmit different diseases. Recently, epidemic diseases such as Japanese encephalitis (Japanese encephalitis for short), dengue fever and the like in partial areas of China have been prevalent, and the infection route of the diseases is mainly through mosquitoes. Mosquitoes are a very common harmful insect in the summer and autumn, and have a hazard to human bodies in that they can transmit pathogens to healthy people after biting a diseased animal or human body.
The mosquito-proof fabric produced by the prior art mostly carries out mosquito prevention by adding various mosquito-killing substances or mosquito-repelling substances, has good mosquito-proof effect, but has two serious defects, namely, the added substances with good mosquito-killing effect have certain harm to human bodies, the mosquito-killing effect harmless to human bodies is poor, and the loss of the mosquito-proof substances in the washing and using processes is faster and can not be lasting.

Effect example
Table1 below gives the analysis results of the mosquito repellent effect and durability of the mosquito repellent fabrics of examples 1 to 3 and comparative examples 1 to 4 according to the present invention.
TABLE 1
| Mosquito-proof rate | Retention rate | Mosquito-proof rate | Retention rate | ||
| Example 1 | 98.8% | 98.6% | Comparative example 1 | 98.6% | 84.6% |
| Example 2 | 99.1% | 98.9% | Comparative example 2 | 82.2% | 86.5% |
| Example 3 | 98.6% | 98.3% | Comparative example 3 | 87.2% | 89.3% |
| Comparative example 4 | 89.2% | 98.2% |
As can be seen from comparison of experimental data of examples 1,2,3 and comparative example 1 in table 1, the retention rate of examples 1,2,3 is high compared with comparative example 1, which indicates that placing 1, 12-dodecanediamine in a core fluid is easier to place substances inside fibers than in a shell fluid, and simultaneously, the subsequently produced polydihydroxy pyrrole is easy to wind and fix in a pore canal, fix internal substances and make the fibers more stable, thereby improving the durability of the anti-mosquito fabric; as can be seen from comparison of experimental data of examples 1,2 and 3 and comparative example 2, the examples 1,2 and 3 and comparative example 2 have high mosquito-repellent rate and retention rate, which indicates that the 1, 12-dodecanediamine is used for aminolysis from the inside, and compared with the 1, 12-dodecanediamine solution for aminolysis, the subsequent reaction is easy to be carried out from the inside, and is not easy to fall off in the reaction process or cause material loss after machine washing after the finished product, thereby improving the mosquito-repellent effect and durability of the mosquito-repellent fabric; as can be found from the comparison of experimental data of the comparative examples 1,2 and 3 and the comparative example 3, the comparative examples 1,2 and 3 have high mosquito-proof rate and retention rate, which indicates that the generated nano titanium dioxide has better chemical stability and sterilization effect compared with ferric oxide, is not easy to be corroded and lost by acid and alkali, thereby better shielding infrared rays emitted by human bodies and improving the mosquito-proof effect and durability of the mosquito-proof fabric; from comparison of experimental data of examples 1,2 and 3 in comparative example 4, the comparative examples 1,2 and 3 in comparative example 4 show that the mosquito-repellent effect of the anti-mosquito fabric is improved by preparing 3, 4-dihydroxypyrrole into pyrrole diester, carrying out primary catalysis to polymerize the pyrrole diester, and carrying out secondary catalysis to hydrolyze the polypyrrole diester, so that the protection of hydroxyl groups can be reduced to form byproducts, and meanwhile, a richer pore structure is formed, and the infrared shielding effect and the adsorption effect on human body sweat are improved.
