Description

Technical Field

[0001] The utility model relates to the technical field of composite membrane products, in particular to a multi-layer solid nanofiber membrane. Background Art

[0002] Common skin care mask products in daily life include facial masks, eye masks, forehead patches, nasolabial fold patches, etc. Regardless of which one, most of them are in the form of non-woven fabrics soaked in essence. There are many active substances with relatively active chemical properties in the essence, which are easy to deteriorate or denature and cannot be preserved for a long time. Therefore, preservatives and other ingredients are often added to the formula of the essence, which does not conform to the consumer concept of no additives, mildness and non-irritation. On the other hand, the solid nanofiber membrane products developed in recent years do not have a special peeling structure, which causes the membrane to be dissolved by the moisture on the hands in advance when peeling, resulting in an incomplete fiber membrane. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems existing in the prior art and provide a multi-layer solid nanofiber membrane. The multi-layer solid nanofiber membrane comprises at least three layers, namely a non-woven fabric base layer 1, a nanofiber membrane layer 2, and a protective layer 3. Convenient strips 5 are arranged at the ends of the non-woven fabric base layer 1 and the protective layer 3.

[0004] Furthermore, the multi-layer solid nanofiber membrane also includes microsphere particles 4 , which are attached to the surface of the nanofiber membrane and are located between the nanofiber membrane layer 2 and the protective layer 3 .

[0005] Furthermore, the thicknesses of the non-woven fabric base layer 1, the nanofiber membrane layer 2, and the protective layer 3 are 0.1 mm-0.5 mm, 10 μm-100 μm, and 0.1 mm-0.5 mm, respectively.

[0006] Furthermore, the multi-layer solid nanofiber membrane is specifically a facial mask, an eye mask, a forehead patch, a cheek patch or a nasolabial fold patch, etc.

[0007] Furthermore, the facial mask is of one-piece or split type, wherein the split facial mask includes a forehead sticker and two left-right symmetrical cheek stickers.

[0008] Furthermore, the eye mask is of one-piece or split type, wherein the split eye mask comprises an upper eye mask and a lower eye mask which are symmetrical in upper and lower parts.

[0009] Compared with the prior art, the utility model has the following advantages: (1) The active ingredients are directly encapsulated in the film layer in solid form, and the obtained solid film product can be quickly dissolved in water, which not only has a longer shelf life but also is more convenient to use, avoiding the use of preservatives; (2) A convenience strip is designed at the edge of the film product, which is convenient for users to pick up and avoid premature dissolution of the fiber film due to the moisture on the fingers, resulting in an incomplete fiber film; (3) Yak skin collagen antioxidant peptides and functional small molecules are selected to prepare the nanofiber film, giving full play to its moisturizing, whitening, anti-aging and other effects, and improving the user experience; (4) The microsphere particles can encapsulate the functional ingredients and reduce the skin tightening caused by too fast water evaporation.

[0017] To enable those of ordinary skill in the art to fully understand the technical solutions and beneficial effects of the utility model, the following further description is made in conjunction with specific embodiments and the accompanying drawings.

[0018] As Figure 1 、 4 shown, a multi-layer solid nanofiber membrane includes a non-woven fabric base layer 1, a nanofiber membrane layer 2, and a protective layer 3 in sequence. Microsphere particles 4 are evenly distributed between the nanofiber membrane layer 2 and the protective layer 3, and a convenience strip 5 for easy picking up is reserved at one end of the non-woven fabric base layer 1 and the protective layer 3.

[0019] The non-woven fabric base layer 1 is made of non-woven fabric, and its thickness is 0.1 mm - 0.5 mm.

[0020] The component of the nanofiber membrane layer 2 is mainly yak skin collagen, which is a small molecule bioactive peptide obtained by enzymatic hydrolysis or hydrolysis of collagen extracted from yak skin. During production, yak skin collagen, fiber-forming substances, water or other solvents are first mixed to prepare a spinning solution, and then a fiber membrane is formed on the non-woven fabric by electrospinning. After sufficient drying, a solid nanofiber membrane layer 2 with a thickness of 10μm - 100μm is obtained.

[0021] The material of the protective layer 3 is non-woven fabric, release paper or pearlescent paper, and its thickness is 0.1mm - 0.5mm.

[0022] The microsphere particles 4 are one or more mask efficacy components such as hyaluronic acid, niacinamide, calendula, retinol, tea polyphenols, etc. Their main functions are moisturizing, whitening, repair, anti-aging, or antioxidant, etc. During production, these microsphere particles are loaded onto the nanofiber membrane layer 2 by electrostatic spraying technology, and then the protective layer 3 is laminated.

[0023] Since this membrane product contains a large amount of nutritious skin care substances, it can quickly dissolve and be absorbed by the skin when exposed to water. Therefore, we have made it into Figures 2 - 6 mask, eye mask, forehead patch and other products in various forms as shown. These membrane products have the effects of moisturizing, whitening, anti-aging, etc., and are expected to obtain good economic benefits after being launched into the market.
