Abstract
Description
Technical Field
[0001] This invention belongs to the field of cosmetic technology, specifically relating to a method for preparing a mud mask or cream mask and its product. Background Technology
[0002] Traditionally, cleansing mud masks and skincare creams are packaged in containers such as jars, bottles, and tubes, and are mostly applied manually. Applying too little results in uneven cleansing power due to insufficient coverage of the skin tone, with some areas having weak absorption. Applying too much increases the burden of subsequent rinsing and may also cause excessive stretching of the skin after drying due to excessive buildup in certain areas. Therefore, they have significant drawbacks in terms of convenience. In recent years, sheet masks and cream masks have emerged, which not only retain the efficacy of masks but also solve the problems of traditional cleansing mud masks and skincare creams being "difficult to apply and wash off." They eliminate the need for manual application, saving time and effort.
[0003] Currently, the processing technology for sheet masks and cream masks is generally as follows:
[0004] The mud film and cream are evenly transferred to the printing layer (non-woven fabric) through the coating unit, and covered with a protective layer (PE). The three-layer patch product is obtained by pressing from the top and bottom using a face mold; the three layers from top to bottom are the protective layer, the functional layer, and the printing layer.
[0005] In the existing process, the coating unit fully coats the substrate, and after covering it with a protective layer, it is cut using a mold. Due to the arc-shaped characteristics of the face mask mold, there is an inevitable gap between the molds, resulting in unavoidable loss of the mud film and cream material, with a loss rate between 35% and 45%.
[0006] Material waste increases product costs, with 35-45% material waste accounting for about 25% of the final product cost; this hinders widespread adoption by price-sensitive consumers.
[0007] Furthermore, the protective layers used in existing products are mostly made of plastic materials such as PE, which does not conform to the current trend of advocating environmentally friendly development; in particular, the increasingly stringent plastic restriction laws in countries and regions such as the EU have limited the promotion of this type of product. Therefore, there is an urgent need to provide a more cost-effective and environmentally friendly method for preparing patch-type mud films to meet application requirements. Summary of the Invention
[0008] To address the shortcomings of existing technologies, this invention provides a method for preparing mud-film or cream-film products, as well as the resulting products.

[0050] (2) The printing substrate (made of polylactic acid fiber nonwoven fabric) is cut into face mask shapes. The face mask shapes are conveyed to the photoelectric positioning system via the conveyor belt of the printing machine. The photoelectric positioning system conveys the face mask shapes directly below the printing screen. Then, the product and screen separation system controls the distance between the printing screen and the face mask shapes to be 8mm. Then, the return blade (right-angle blade, speed 5m / min) and the scraper blade (right-angle blade, speed 5m / min) remove the active ingredient on the printing screen at a rate of 0.2g / cm. 2 The printed face mask is transferred to the left half of the front of the mask and finally output through the conveyor belt by the automatic detection photoelectric system.

[0053] Example 3
[0054] This embodiment provides a mud mask, the preparation method of which is as follows:
[0055] (1) Prepare an active ingredient with a solid content of 65%, and then put the active ingredient into a printing press;
[0056] The printing machine includes a conveyor belt, a photoelectric positioning system, an automatic feeding system, a printing screen (30 mesh), a return knife, a scraper knife, a printing screen fixing bracket, a printing screen up and down movement track, a scraper (return) knife up and down movement track, a product and printing screen separation system, and an automatic output detection photoelectric system.
[0057] (2) The printing substrate (a nonwoven fabric made of polylactic acid fiber and lyocell fiber) is cut into face mask shapes. The face mask shapes are conveyed to the photoelectric positioning system via the conveyor belt of the printing machine. The photoelectric positioning system guides the face mask shapes directly below the printing screen. Then, the product and screen separation system controls the distance between the printing screen and the face mask shapes to 3mm. Finally, the return blade (V-shaped blade, speed 10m / min) and the scraper blade (V-shaped blade, speed 10m / min) remove the active ingredient from the printing screen at a rate of 0.1g / cm. 2 The printed face mask is transferred to the left half of the front of the mask and finally output through the conveyor belt by the automatic detection photoelectric system.
[0058] (3) Fold the half of the face mask that was not coated with the active ingredient after step (2) and cover it with the surface of the active ingredient to obtain the mud mask.
[0059] Using the printing press and method described in this invention to prepare 100 pieces of mud film, the loss rate of the required functional material is 4.8%, and the loss rate of the nonwoven fabric is 3.8%.
[0060] Example 4
[0061] This embodiment provides a mud-like film. The preparation method of the mud-like film differs from that of Embodiment 1 only in that the solid content of the active ingredient in step (1) is 40%, while the remaining steps are the same as in Embodiment 1. When the solid content is too low, the viscosity of the active ingredient is low, and its fluidity is good. When the active ingredient is transferred to different fiber substrates through the printing screen, it will quickly penetrate the micropores between the fibers, resulting in the distribution of the active ingredient on the non-printing surface of the substrate, which is not conducive to consumer use.
[0062] Example 5
[0063] This embodiment provides a mud mask. The preparation method of the mud mask differs from that of Embodiment 1 only in that the solid content of the active ingredient in step (1) is 90%, while the remaining steps are the same as in Embodiment 1. Because the solid content of the active ingredient is too high, not only is the cost too high, but the viscosity is also too high, resulting in an oily feeling after use.
[0064] Comparative Example 1
[0065] This comparative example provides a mud-covered film, which is prepared by a conventional method. The specific steps are as follows: an active ingredient (with the same solid content as in Example 1) is coated onto a non-woven fabric, and the film is cut out with a roller to obtain the mud-covered film.
[0066] Using the method described in this comparative example, 100 mud masks were prepared, with a loss rate of 40.8% for the required active ingredients and a loss rate of 45.2% for the nonwoven fabric.
[0067] As can be seen from the above embodiments and comparative examples, compared with the prior art (Comparative Example 1), the mud film prepared by the method of the present invention has lower loss of active ingredients and non-woven fabric, and no protective film is required after preparation, which not only greatly reduces the process cost, but is also more environmentally friendly.
[0068] The applicant declares that this invention illustrates a method for preparing a mud mask or cream mask and its product through the above embodiments, but this invention is not limited to the above embodiments, that is, it does not mean that this invention must rely on the above embodiments to be implemented. Those skilled in the art should understand that any improvements to this invention, equivalent substitutions of the raw materials of the product, addition of auxiliary components, and selection of specific methods, etc., all fall within the protection scope and disclosure scope of this invention.
[0069] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0070] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.
