Abstract: With the progress of the times, people's awareness of their skin health care has been growing in recent years, and functional textiles for skin health have increasingly attracted people's attention and pursuit. Vitamin E loaded cosmeto-textiles are textiles that add vitamin E to textile materials to play a skin care function. Compared with traditional skin care products, vitamin E loaded cosmeto-textiles have a longer time and a larger area of close contact with skin, and their ingredients cover the skin more evenly. Moreover, because of the barrier effect of the fabric, the skin care effect is much better.
Due to the unstable properties of vitamin E, it can not be directly added to textiles, and must be transformed into vitamin E derivatives or loaded by carriers to maintain its biological activity. At present, vitamin E loaded cosmeto-textiles are mainly prepared by blending spinning or finishing. Specifically, vitamin E is first converted into its derivatives or loaded by various carriers such as cyclodextrin, microcapsule, microemulsion and sol-gel to maintain its biological activity, and then skin care functional fibers containing vitamin E are produced by spinning or the vitamin E is fixed on the fabric by after finish. The conversion technology of vitamin E derivatives is to transform vitamin E into stable derivatives through structural modification to ensure that it can play a stable role in the body, and this process is suitable for the preparation of disposable products. Cyclodextrin is an organic substance, which can wrap up vitamin E and protect it from oxidation and degradation. Vitamin E microcapsule is a kind of micro particle formed by coating vitamin E with polymer film materials. It can protect the stable existence of vitamin E and has excellent slow release performance. Microcapsule is one of the most widely used preparation technologies in vitamin E loaded cosmetotextile products in recent years. Microemulsion can be used as the carrier of vitamin E to make it better dispersed in liquid and improve its solubility and volatility in spinning solutions or finishing agents. Nonetheless, due to a variety of unavoidable shortcomings, the use of microemulsion has gradually decreased currently. Sol-gel method can solidify and embed vitamin E and the gel can form a close interaction with fabric fibers. However, this method requires a large number of organic compounds, with high cost and long processing time, so it is rarely used at present.
The skin care properties of vitamin E loaded cosmeto-textiles are characterized by vitamin E content, vitamin E slow release property and washing resistance.
At present, the crux of difficulties for the study of vitamin E loaded cosmeto-textiles mainly falls into two points: how to better control the release of vitamin E in textiles and how to improve the washing resistance. In order to better solve the above problems, we can start from the following aspects: first, it is necessary to optimize the preparation process, start from a more refined production level, and make the raw material preparation closer to the nanometer level; second, it is necessary to introduce new technologies such as solid lipid nanoparticles embedding technology and the dermotextile technology to find a better production mode; third, the formulation and improvement of relative testing methods and standards are also of great significance for the development of vitamin E loaded cosmeto-textiles.
