Problems solved by technology

[0003]In recent years, the research and development of mosquito-repellent polyurethane and its fibers are attracting attention due to the needs of many field operations such as military field training, summer fishing and summer indoor mosquito repellent. The market application of the product is very broad. Although there are many mosquito repellent spandex products in the prior art, the existing mosquito repellent spandex has poor mosquito repellent effect and can only drive away a small number of mosquitoes. At the same time, the existing mosquito repellent spandex continues to The effect is shorter and it is easy to lose the repellent effect

Abstract

The invention provides a preparation method of mosquito-repellent spandex, and relates to the technical field of spandex preparation. The mosquito-repellent spandex consists of the following raw materials in parts by weight: 100 to 120 parts of polytetramethylene ether glycol, 10 to 12 parts of 4,4-diphenylmethane diisocyanate, 120 to 160 parts of dimethylacetamide, 20 to 30 parts of mint fiber, 12 to 16 parts of a chain extender, 8 to 12 parts of natural bamboo fiber, 8 to 10 parts of a mosquito repellent and 7 to 9 parts of an auxiliary agent. The mosquito repellent conssits of a nepenthes extract, a cordate telosma extract, a lavender extract and a passion fruit extract. According to the preparation method, by reasonably using the raw materials and the process flow, the mosquito-repellent time of the prepared mosquito-repellent spandex is significantly prolonged, various performances of the mosquito-repellent spandex are improved, the mosquito-repellent effect of the mosquito-repellent spandex is substantially improved, the number of the mosquito-repellent mosquitoes is significantly increased, and the prepared fabric is comfortable and soft to wear, so that the quality of the mosquito-repelling spandex is improved.

Description

technical field [0001] The invention relates to the technical field of spandex preparation, in particular to a preparation method of mosquito repelling spandex. Background technique [0002] Spandex has excellent elasticity, and its strength is 2-3 times higher than that of latex silk, its linear density is also finer, and it is more resistant to chemical degradation. Well, the spandex fiber has such high elasticity because its polymer chain is composed of a low-melting point, amorphous "soft" segment as the matrix and a high-melting point, crystalline "hard" segment embedded in it. The molecular chains of the flexible segment form a certain network structure with a certain cross-linking. Due to the small interaction force between the molecular chains, they can freely expand and contract, resulting in large elongation performance. [0003] In recent years, many field work projects such as military field training, summer fishing and summer indoor mosquito repellent and other...
