Mint-extract, menthol and cool-feeling-substance combined modification additive and application thereof

Abstract

The invention belongs to the technical field of functional cellulosic fibers, and relates to a mint-extract, menthol and cool-feeling-substance combined modification additive. A preparing method of the mint-extract, menthol and cool-feeling-substance combined modification additive includes the steps that acrylonitrile monomers and menthol are added into an emulgator solution, and emulsification pretreatment dispersing is carried out to obtain a mixed emulsion solution of the menthol and acrylonitrile; the mixed emulsion solution is heated and stirred while initiators are dropwise added, microcapsules are prepared, and the microcapsules are dispersed into distilled water after washing and drying; cool feeling substances are added into a mint-extract solution, stirring and adsorption are carried out, cool-feeling-substance dispersion liquid with mint extract is obtained, the dispersing liquid is dried and ground, and cool-feeling substance powder with the mint extract is prepared; the menthol microcapsule slurry and the cool-feeling substance powder with the mint extract are mixed to be even, and the combined modification additive is prepared through the adsorption effect of the cool feeling substances and the protection effect of the microcapsules. Functional cellulosic fibers prepared with the combined modification additive have the lasting cool feeling effect and the anti-bacterial function.

Description

technical field [0001] The invention belongs to the technical field of functional cellulose fibers, and in particular relates to a composite modified additive of mint extract, menthol and cool feeling substances prepared from peppermint extract, menthol and cool feeling substances, which is used to prepare long-lasting Mint viscose with cooling effect and antibacterial function. Background technique [0002] Viscose fiber products have the characteristics of moisture absorption, good air permeability and comfortable wearing, and have been widely used. However, most viscose fibers in my country are ordinary varieties, and there are few functional fibers and most of them have not been industrialized. Therefore, vigorously developing new varieties of viscose fibers with high performance and differentiation to meet the needs of domestic and foreign markets is the development of the viscose fiber field. important direction. [0003] Peppermint extract and peppermint oil are effe...

AI Technical Summary

Problems solved by technology

After microencapsulating peppermint oil, it is added to the viscose collagen solution for spinning, wherein the prepared peppermint oil microcapsules have a particle size of 60-200 μm, which is too large, and are not suitable for spinning viscose fibers. limit its application

At the same time, in the process of microcapsule preparation, the amount of peppermint oil is less, and there are no other cooling substances for functional compounding, which will affect the cooling effect of the fiber

[0009] In the prior art, there is a lack of new composite additives with cooling effect and mint antibacterial function. The existing preparation method of mint composite cellulose fiber has the problem that the added mint extract is easily decomposed and lost, which reduces the antibacterial effect of the fiber. Function; the cooling effect of the fiber prepared by the existing cold antibacterial fiber preparation method is poor, and it cannot be widely used in the preparation of cool feeling cellulose fiber
