[0042] 2. Preparation of nanofiber membrane: use ultra-high voltage and multi-nozzles to electrospin the electrospinning liquid, control the humidity of the electrospinning environment to 20%-80%, the spinning distance to 30mm-600mm, and the spinning voltage to be 30kV-80kV, obtain single-layer or multi-layer nanofiber membrane. Preferably specifically: the preparation of a single-layer nanofiber membrane: the electrospinning solution C and the electrospinning solution A (or B) are prepared by using an ultra-high voltage, multi-nozzle electrospinning device to prepare a single-layer nanofiber membrane, and receive The surface is collected simultaneously and spun by different nozzles to obtain a single functional layer blended membrane (functional substances loaded in the skeleton or gel matrix) including the nanofiber insoluble skeleton and the nanofiber gel matrix, and the humidity of the spinning environment is controlled to be 20 %-80%, the spinning distance is 30mm-600mm, ...

Embodiment 1

[0047] This embodiment provides a single-layer nanofiber membrane paper with moisturizing function, which is prepared by the following method:

[0048] 1) Preparation of polymer carrier solution: polylactic acid was dissolved in hexafluoroisopropanol at room temperature to obtain electrospinning solution A with a mass concentration of 15%.

[0049] 2) Preparation of moisturizing functional gel matrix solution: put polyvinyl alcohol with a degree of polymerization of 500 and a degree of alcoholysis of less than 90% into deionized water, stir at room temperature for 0.5 hours to fully dissolve the sample, and heat to above 60°C Stir for 1 hour to obtain a polyvinyl alcohol aqueous solution with a mass fraction of 9%; the chitosan with a carboxylation degree of 80% and a relative molecular weight greater than 500KDa is dissolved in a 0.2mol / L aqueous acetic acid solution under heating and stirring at 60°C to obtain Chitosan acetic acid aqueous solution with a mass fraction of 12%...

Embodiment 2

[0054] This embodiment provides a multilayer nanofiber film paper with moisturizing and whitening functions, which is prepared by the following method:

[0055] 1) Preparation of polymer carrier solution: polylactic acid was dissolved in hexafluoroisopropanol at room temperature to obtain electrospinning solution A with a mass concentration of 15%.

[0056] 2) Preparation of gel matrix solution: put polyvinyl alcohol with a degree of polymerization of 500 and a degree of alcoholysis of less than 90% into deionized water, stir at room temperature for 0.5 hours to fully dissolve the sample, heat to above 60°C and stir for 1 hour , make the polyvinyl alcohol aqueous solution of mass fraction 9%; Be that the carboxylation degree is 80%, the chitosan of relative molecular weight greater than 500KDa is dissolved in the acetic acid aqueous solution of 0.2mol / L under 60 ℃ heating and stirring, obtains mass fraction as 12% chitosan acetic acid aqueous solution; then chitosan acetic aci...

Abstract

The invention discloses ultra-thin ultra-dryness nanometer fiber mask paper and a preparation method, and relates to the technical field of mask materials and preparation. The ultra-thin ultra-drynessnanometer fiber mask paper is mask paper with the thickness being 0.04-0.12 mm and the water content being 4-6%. The paper is prepared from, by weight, a nanometer fiber skeleton made of a polymer carrier including a non-water-soluble polymer, and a gel substrate and functional substances attached to the nanometer fiber skeleton. The mask paper is similar to paper in appearance, the water contentis quite low, no corrosion remover needs to be added, the phenomenon that skin irritation, sensitivity and other adverse effects are caused by corrosion removers is avoided, and the safety is bettercompared with a traditional water-base mask. The non-water-soluble or unstable functional ingredients are attached to the nanometer fiber adopting the macromolecular polymer as the carrier, the functional ingredient stability is greatly improved, and the problems that the ingredients are compatible difficultly, easy to degrade and not high in bioavailability are solved.

Description

technical field [0001] The invention relates to the technical field of mask materials and preparation, in particular to an ultra-thin and ultra-dry nanofiber membrane paper and a preparation method. Background technique [0002] Skin care is an important part of the cosmetic industry and aesthetic medicine. In the traditional beauty process, cosmetic formula products such as cream lotion, lotion, etc. are directly applied to the skin, or the film liquid rich in functional ingredients is in contact with the skin with the help of mask paper (generally non-woven fabric), and through osmosis Make the moisture, nutrients and functional ingredients in the cosmetic or film formula enter the stratum corneum and the lower layers of the skin, so as to achieve the purpose of beauty and skin care. Among them, facial mask products are popular among consumers because of their ease of use and quick results. Traditional facial masks are mostly composed of non-woven film cloth and film liq...
