preparation example Construction

[0054] A preparation method of any one of the above water-soluble non-woven facial masks, comprising the following steps:

[0055] S1. preparing a water-soluble spinning solution comprising polyvinyl alcohol, water-soluble chitosan and hyaluronic acid;

[0056] In step S1, under step temperature conditions of 25-90°C and a stirring rate of 100-300r / min, PVA, water-soluble chitosan, hyaluronic acid and auxiliary materials are added to the solvent water in batches, and mechanically Stir for 1-3 hours to prepare a water-soluble spinning solution.

[0057] Preferably, the preparation process of the mixed spinning solution is: in the process of continuously stirring the solvent water at a stirring rate of 100-300r / min, adding PVA and water-soluble chitosan in sequence, wherein the temperature of the solvent water is controlled at 90°C and below.

[0058] Preferably, after adding the water-soluble chitosan, the temperature in the mixed solution is controlled below 80°C.

[0059] ...

Embodiment 1

[0071] Embodiment 1 of the present invention provides a kind of preparation method of water-soluble non-woven facial mask, comprises the steps:

[0072] S1, preparation of mixed spinning solution: Add PVA, water-soluble chitosan, hyaluronic acid and auxiliary materials to the solvent water in batches under the step temperature condition of 25-90°C and the stirring rate of 300r / min, and carry out Mechanically stirring for 2.5 hours to prepare a mixed spinning solution;

[0073] In the mixed spinning solution, the preparation of each component is by mass percentage as follows:

[0074]

[0075] The specific process of preparation is:

[0076]S11, in the process of continuously stirring the solvent water at a stirring rate of 300 r / min, add PVA and water-soluble chitosan in sequence, wherein the temperature of the solvent water is controlled at 90° C. or below.

[0077] S12, after adding the water-soluble chitosan, the temperature in the mixed solution is controlled below 80...

Embodiment 2-6 and comparative example 1-4

[0082] The difference from Example 1 lies in: the raw material preparation ratio and the settings of the centrifugal spinning process are different, as shown in Table 1 below.

[0083] Table 1 embodiment 1-7 and the process parameter and test result of comparative example 1-4

[0084]

[0085]

[0086] The electron micrograph of the water-soluble non-woven facial mask that embodiment 1 prepares is as figure 1 shown. from figure 1 with Image 6 It can be seen from the figure that the diameter distribution of the ultrafine fibers of the water-soluble non-woven mask prepared in Example 1 is uniform, mainly concentrated in the fiber fineness of about 9-10um, and the fiber diameter is distributed in the range of 0.5-14μm.

[0087] The electron micrograph of the water-soluble non-woven facial mask that embodiment 2 prepares is as figure 2 shown. from figure 2 with Figure 7 It can be seen from the figure that the diameter distribution of the ultrafine fibers of the wa...

Abstract

The invention provides a water-soluble non-woven fabric mask and a preparation method thereof. High-content mask effective components are prepared into a water-soluble spinning solution by adopting a spinneret device additionally provided with a stirrer or a plane receiving type centrifugal spinning device comprising a plurality of spinneret devices in the vertical direction, and then spinning is performed to obtain a dry fiber-based mask. When in use, the mask is soaked in water to dissolve out effective components in water-soluble fiber, and then the mask is applied for use; or the wet water-soluble non-woven fabric mask is directly applied for use, so that the effective components are gradually leached out for a user to absorb. Through the operation, no preservative needs to be added, the effective components only need to be leached out through the water in the using process, then the mask is applied for use, and the maintenance effect can be achieved. By improving a centrifugal spinning process, centrifugal spinning of the spinning solution with high content of the effective components is realized, and an effective way is provided for large-scale application of the non-woven fabric mask.

Description

technical field [0001] The invention relates to the technical field of preparation of biological materials and non-woven materials, in particular to a water-soluble non-woven facial mask and a preparation method thereof. Background technique [0002] Non-woven fabrics are often used in the field of cosmetics, such as facial mask paper materials, due to their flexibility, skin-friendliness, and hygroscopicity. By infiltrating and absorbing effective moisturizing and maintenance ingredients into the non-woven mask paper, and then attaching the mask paper to the part to be maintained, the active ingredients are in contact with the part to be maintained, and the gradual absorption of the active ingredients is realized. For example, macromolecular hyaluronic acid can act on the surface of the skin, making the skin smooth and moist, and can block certain external damage, such as ultraviolet rays, dust, bacteria, etc. The small-molecule hyaluronic acid can penetrate deep into the ...
