Description

Technical Field

[0001] The invention relates to the technical field of facial masks, and in particular to a method for preparing a hydrogen-rich membrane cloth. Background Art

[0002] Hydrogen is the smallest molecule in the universe. It can enter cells such as the nucleus and mitochondria. It has strong penetration and can be directly taken into the human body through the skin and breathing. Existing medical research has shown that hydrogen can effectively reduce and remove active oxygen free radicals in the human body, improve oxygen free radicals and energy metabolism, and has a good improvement and control effect on various lesions in the body, such as anti-aging, skin anti-inflammatory, and anti-fatigue. Facial mask is a skin care product. The most basic and important purpose is to make up for the insufficient cleaning work of makeup removal and face washing. On this basis, it is combined with other essence ingredients to achieve other maintenance functions, such as hydration, whitening, anti-aging, and balance oil. Facial mask is a carrier of beauty care products. The main forms include mud paste type, tear type, gel type and wet wipes type. Using the time covered on the face, it temporarily isolates the outside air, which is conducive to the skin to discharge the products of epidermal cell metabolism and accumulated oil substances. The moisture in the mask penetrates into the stratum corneum of the epidermis, making the skin soft and naturally bright and elastic. In terms of convenience, the main types are gel-type and wet tissue-type. However, gel-type masks are mainly sleeping masks, which can be washed or not after application, similar to skin cream. In terms of user experience, wet tissue-type masks are more advantageous and more popular. The existing mask cloth is composed of a kapok fiber layer and a viscose fiber layer stacked on the top surface of the kapok fiber layer. The fiber web of the kapok fiber layer is combed by an air-laid process, and the fiber web of the viscose fiber layer is combed by a mechanical combing process, and has poor moisturizing, softness and comfort.
