Abstract

The invention relates to a preparation method of mosquito repellent viscose fiber. The preparation method comprises the following steps: preparing a l PMD (p-menthane-3,8-diol)l dispersion solution ora lemon eucalyptus leaf oil dispersion solution, preparing a sodium carboxymethyl cellulose solution and preparing a uniform mixed solution of the dispersion solution and the sodium carboxymethyl cellulose solution; continuously blending the mixed solution and a spinning viscose stock solution in a ratio of 1:50-1:20 in a pre-spinning injection device, feeding the solution in spinning equipment for spinning after uniform dispersion, and performing drafting, cut-off, desulfurizing, washing, bleaching, pickling, washing, oiling, drying and the like on fiber obtained by spinning to prepare the mosquito repellent viscose fiber. A mosquito repellent is prepared from lemon eucalyptus leaf oil and extracts of the lemon eucalyptus leaf oil, and has the characteristics of being natural and safe; the fiber is easy to prepare and low in cost; the mosquito repellent viscose fiber not only can maintain basic characteristics of viscose fiber, but also has a long-acting mosquito repelling function,can be used for preparing textiles with a mosquito repelling function, and has good industrialization and market application prospects.

Description

technical field [0001] The invention relates to the technical field of chemical fiber processing, in particular to a preparation method of mosquito repellent viscose fiber. Background technique [0002] Many diseases (malaria, filariasis, dengue fever, Japanese encephalitis, etc.) originate from mosquito bites. Because the textiles used in people's lives are in close contact with human skin, with the development of science and technology and the improvement of living standards, people There is a greater demand for textiles with mosquito repellent properties. [0003] The hygroscopicity of viscose fiber is higher than that of cotton, which is very suitable for the physiological requirements of human skin, and has been widely used in the fields of textile and clothing, non-woven fabrics and medical hygiene materials. As the temperature rises, people's outdoor activities also increase, so the development of viscose fiber with mosquito repellent function has important applicati...
