Abstract

The invention relates to a multifunctional fabric containing mosquito-repellent microcapsules and a preparation method thereof. The preparation method comprises the following steps: 1) preparation ofan essential oil emulsion: taking mosquito-repellent aromatic essential oil, adding the mosquito-repellent aromatic essential oil into an aqueous solution of polyethylene glycol, adding a surfactant,and carrying out high-speed stirring and emulsification so as to obtain the mosquito-repellent aromatic essential oil emulsion; 2) preparation of microcapsules: separately weighing gelatin and Arabicgum, adding the weighed gelatin and Arabic gum into distilled water, carrying out stirring until the gelatin and Arabic gum are completely dissolved so as to prepare a gelatin and Arabic gum solution,adding the essential oil emulsion, then carrying out stirring with a homogenizer, and carrying out emulsification, re-coagulation and curing; and 3) finishing of the fabric: taking the prepared microcapsule emulsion, adding an adhesive, water and a penetrant, carrying out uniform stirring and dispersion, padding the emulsion onto the fabric by using a padding method, and carrying out baking and drying so as to obtain the aromatic mosquito-repellent fabric. The fabric has good persistent mosquito-repellent and aromatic functions.

Description

technical field [0001] The invention belongs to the field of functional textiles, in particular to a fabric containing mosquito-repelling microcapsules and a finishing method thereof. Background technique [0002] Mosquitoes are common creatures in life. They mainly feed on the blood of humans and animals. After being bitten by mosquitoes, they not only cause itching and pain, but also spread Japanese encephalitis, malaria, dengue fever and other diseases, causing great harm to human health. harm. The research report of the World Health Organization clearly pointed out that among all diseases transmitted by pests, mosquitoes bear the brunt, so mosquito repellent has always been a concern of people. [0003] The anti-mosquito agent that people adopt at present is mainly chemically synthesized anti-mosquito agent; But this kind of anti-mosquito agent has very big harm to human body and environment; People pay more and more attention to environmental protection today obviously...
