Problems solved by technology

The base fabric layer of common masks on the market is mainly non-woven fabrics. The fibers of non-woven fabrics are generally thicker, about a dozen microns, and the size of facial skin grooves is between 50-60nm, so non-woven fabric masks are skin-friendly and soft. Poor, and poor fit with the face
Mask essence is easily contaminated during packaging and use, some active substances are easily oxidized and deteriorated in a liquid state, and excess essence that cannot be absorbed by the skin also causes a waste of resources

preparation example Construction

[0040] The preparation method of the nanofiber mask base cloth containing silk protein, comprises the following steps:

[0041] Step 1: Dissolve polyvinyl alcohol in deionized water to prepare a polyvinyl alcohol solution with a mass fraction of 10% to 12%; then add silk peptide to the prepared polyvinyl alcohol solution to obtain a mixed solution, and the silk peptide in the mixed solution The quality of the polyvinyl alcohol is 10% to 20% of the mass of polyvinyl alcohol; the polyvinyl alcohol is 1788 type, the molecular weight is 44.05, and the degree of alcoholysis is 87.0% to 89.0%;

[0042] Step 2: Fully stir the mixed solution prepared in Step 1 at 50-70°C for 4-6 hours to form a homogeneous transparent solution, let it stand at room temperature for 2-3 hours and then defoam for later use to obtain a spinning solution;

[0043] Step 3: Electrospinning the spinning solution, the parameters of electrospinning include: voltage 14-20kV, flow rate 0.4-1.0mL / h, receiving dist...

Embodiment 1

[0049] Accurately weigh 0.6g of polyvinyl alcohol with an electronic balance and add it to 4.4g of deionized water to obtain a polyvinyl alcohol solution with a mass fraction of 12%, then weigh 0.06g of silk peptide and add it to the polyvinyl alcohol solution, and the solution Place in a constant temperature magnetic stirrer and stir at 50°C for 6 hours until a uniform and transparent solution is formed, so that the silk peptide is fully dissolved in the polyvinyl alcohol solution, take out the spinning solution, and stand at room temperature for 2 hours for degassing. Add 0.06 g of nicotinamide to the spinning solution prepared in the first step, place the solution on a magnetic stirrer, stir at room temperature for 3 hours, and let stand at room temperature for 2 hours to defoam for later use. Electrospinning is carried out on an electrospinning machine, the spinning voltage is 14kV, the flow rate is 0.4mL / h, the receiving distance is 14cm, the roller speed is 700r / min, the ...

Embodiment 2

[0051] Accurately weigh 0.6g of polyvinyl alcohol with an electronic balance and add it to 4.4g of deionized water to obtain a polyvinyl alcohol solution with a mass fraction of 12%, then weigh 0.1g of silk peptide and add it to the polyvinyl alcohol solution, and the solution Place in a constant temperature magnetic stirrer, stir at 60°C for 5 hours until a uniform and transparent solution is formed, fully dissolve the silk peptide in the polyvinyl alcohol solution, take out the spinning solution, and let it stand at room temperature for 2 hours for defoaming. Add 0.1 g of hyaluronic acid to the spinning solution prepared in the first step, place the solution on a magnetic stirrer, stir at room temperature for 2 hours, and let it stand at room temperature for 2 hours for defoaming. Electrospinning was carried out on an electrospinning machine, the spinning voltage was 20kV, the flow rate was 0.4mL / h, the receiving distance was 18cm, the roller speed was 300r / min, the ambient h...

Abstract

The invention discloses nanofiber mask base cloth containing fibroin, a functional mask and a preparation method of the functional mask, and belongs to the technical field of skin care products. A spinning solution obtained by mixing silk peptide and polyvinyl alcohol contains silk protein, and then the nanofiber mask base cloth containing the silk protein is produced by adopting a relatively mature and stable electrostatic spinning technology, so that fibers with nanoscale diameters can be obtained; the nano-scale silk peptide contained in the mask is extremely easy to be fully absorbed and utilized by the face in the use process of the mask, and has good biocompatibility; the added functional substances can be confined in the nanofibers and can be released after meeting water, so that a nursing effect is achieved. The raw materials are green and natural, and the prepared mask base cloth is excellent in performance parameter and good in face fitting performance; the prepared functional mask can well protect functional components in a solid state, is released after meeting water, is easy to store and convenient to use, and can realize batch production.

Description

technical field [0001] The invention belongs to the technical field of skin care products, and in particular relates to a nanofiber facial mask base cloth containing silk protein, a functional facial mask and a preparation method thereof. Background technique [0002] The traditional facial mask consists of two parts, the base fabric layer of the mask and the essence of the mask. The base fabric layer of common masks on the market is mainly non-woven fabrics. The fibers of non-woven fabrics are generally thicker, about a dozen microns, and the size of facial skin grooves is between 50-60nm, so non-woven fabric masks are skin-friendly and soft. Poor, and poor fit with the face. Mask essence is easily contaminated during packaging and use, some active substances are easily oxidized and deteriorated in a liquid state, and excess essence that cannot be absorbed by the skin also causes a waste of resources. Contents of the invention [0003] In order to solve the above proble...
