The invention discloses an anti-mosquito finishing process of a textile fabric. The textile fabric is cotton, tencel, modal, blended cotton (viscose cotton, polyester cotton, polyamide cotton), silk, a wool cotton dyed fabric, a thin chemical fiber fabric, a pair of socks, a mosquito net and the like. The process comprises the steps of: selecting a mosquito repellent and a low-temperature fixative, carrying out nano microencapsulation on the mosquito repellent by utilizing a microencapsulation technology, carrying out anti-mosquito finishing on a textile fabric to form an anti-mosquito emulsion through the low-temperature fixative, dehydrating and curing to finally obtain the anti-mosquito finished fabric. The anti-mosquito fabric fabricated by the anti-mosquito finishing process has a fast mosquito killing function, a repelling rate of the anti-mosquito finishing process on aedes albopicus, culex pipiens pallens and the like is higher than 90 percent and an anti-biting rate of the anti-mosquito finishing process is 100 percent; the anti-mosquito fabric does not have bad influence on physical indices such as appearance, strength, moisture absorbing property and the like of the fabric; the anti-mosquito fabric has a good anti-mosquito effect after being washed 15 times; and the anti-mosquito finished fabric does not stimulate or cause allergy to skin, is safe and non-toxic to ahuman body, and is comfortable to wear.
