Abstract

The invention belongs to the technical field of textile fabric processing, and discloses a preparation method of cotton fabric with mosquito repellent function. The preparation method includes: after the cotton fabric is treated with pectinase and plasma, immersed in a fabric finishing liquid prepared from phthalic anhydride, diethylamine, Streptomyces fermented extract and ionic liquid, and then taken out The cotton fabric with mosquito repellent function is prepared by washing and drying. The cotton fabric prepared by the preparation method has a long-term mosquito repellent effect, and the preparation method is simple in process.

Description

technical field [0001] The invention relates to the technical field of textile fabric processing, in particular to a method for preparing cotton fabric with mosquito repelling function. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, the functional requirements for textiles have also increased accordingly. Mosquito bites have been perplexing people's life in summer always, and various insecticides, mosquito-repellent incense sheets, insecticidal liquids and other products for killing and killing mosquitoes have been invented for this reason. However, due to the relatively high concentration of mosquito-killing agents, it will be more or less poisonous to the human body; and insecticides and other insect-killing tools are passive mosquito-killing modes, and mosquitoes will be released after killing mosquitoes, which cannot be maintained for a long time. The effect of killing mosquitoes. [0003] ...
