Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric technology for facial masks, specifically to a composite fiber nonwoven fabric for facial masks and its preparation method. Background Technology

[0002] The non-woven fabric of the mask is used to hold the essence of the mask. By applying the mask to the face, it can achieve effects such as soothing, moisturizing and whitening.

[0003] For example, Chinese patent CN201910180690.6 discloses a natural ingredient nonwoven fabric mask substrate and its preparation method, which uses chitosan to modify alginate fibers to ensure the moisturizing performance of the nonwoven fabric. However, the liquid retention rate, average air permeability, moisture permeability, and water retention of the above-mentioned nonwoven fabric mask still need further optimization.

[0004] Based on this, the present invention designs a composite fiber nonwoven fabric for facial masks and its preparation method to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a composite fiber nonwoven fabric for facial masks and a method for preparing the same.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A composite fiber facial mask nonwoven fabric includes the following raw materials: ramie fiber, seaweed fiber, fish scale collagen peptide, polyethylene oxide, sodium alginate, xylo-glucosidase, and gelatinized starch.

[0008] Furthermore, the weight ratio of ramie fiber to seaweed fiber is 1:(0.6-1).

[0009] Furthermore, the weight ratio of fish scale collagen peptides, gelatinized starch, polyethylene oxide and sodium alginate is 15:(2-4):(1-3):(0.5-1).

[0010] Furthermore, the weight ratio of fish scale collagen peptides to *Acetobacter xylinum* is 30:(0.5–1).

[0011] A method for preparing a composite fiber facial mask nonwoven fabric includes the following steps:

[0012] I. Composite fibers prepared using ramie fiber and seaweed fiber;

[0013] II. Preparation of fermentation broth for *Acetobacter xylosiderin*;

[0014] III. Electrospinning solution was prepared using fish scale collagen peptides, polyethylene oxide, sodium alginate, gelatinized starch, and xylospora xyloside fermentation broth.

[0015] IV. The electrospinning solution is combined with composite fibers using an electrospinning method to obtain composite fiber nonwoven fabric for facial masks.

[0016] Furthermore, step one includes the following steps: after mixing ramie fiber and seaweed fiber, the mixture is softened by water immersion, steam bursting, carding, hydroentangling reinforcement, dehydration, and drying to obtain composite fiber.

[0017] Furthermore, step two includes the following steps: inoculating *Acetobacter xylodis* into the culture medium, stirring and culturing, and allowing it to ferment statically.

[0018] Furthermore, *Acetobacter xylodis* was inoculated into the culture medium, and cultured at 26–30°C with stirring for 10–13 hours, followed by static fermentation for 5–6 hours.

[0019] Furthermore, step three includes the following steps: mixing fish scale collagen peptides, polyethylene oxide, sodium alginate and gelatinized starch, stirring and reacting, then adding xylo-glucosidase fermentation broth, and continuing to stir and react.

[0020] Furthermore, fish scale collagen peptides, polyethylene oxide, sodium alginate, and gelatinized starch are mixed and stirred at 25–32°C for 3–5 hours. Then, xylo-glucosidase fermentation broth is added and stirred at 27–29°C for 2–5 hours.

[0021] Beneficial effects

[0022] The composite fiber nonwoven mask fabric of the present invention is prepared by using ramie fiber and seaweed fiber to prepare a mask substrate with good air permeability and moisture permeability, and using fish scale collagen peptide, polyethylene oxide, sodium alginate and gelatinized starch to prepare a spinning solution. The spinning solution is mixed with a fermentation broth prepared by *Acetobacter xylinum*, and the fermentation broth and spinning solution are modified. Finally, the modified spinning solution is compounded with the mask substrate to obtain a composite fiber nonwoven mask fabric with high liquid retention, good average air permeability, good moisture permeability and good water retention.
