Abstract

The invention discloses a preparation method of a dry nano-fiber facial mask. The preparation method comprises the following steps: preparing a polyvinyl alcohol water solution, a chitosan water solution, a sodium hyaluronate water solution and a nutrient solution; mixing the water solutions to form a spinning solution, carrying out multi-needle electrostatic spinning, and finally forming a layerof nano-fiber film on a facial mask non-woven fabric base material serving as a receiving screen, so as to obtain a composite fiber film; drying at 70-80 DEG C for 2-5 minutes; and carrying out slitting, formation, sealed packaging and sterilization, so as to obtain the dry nano-fiber facial mask. According to the preparation method, effective components in facial mask liquid are mixed into a polyvinyl alcohol spinning base solution, the nano-fibers are prepared by virtue of an electrostatic spinning technique and fixed on a facial mask non-woven fabric, the facial mask is taken out in use, aproper amount of purified water is sprayed to the front surface of the facial mask to adequately wet the facial mask, and then the facial mask can be applied to the face of a user. The water content is extremely low before use, and natural chitosan type antibacterial components are added, so that the guarantee period is prolonged, and the facial mask is convenient to transport and store.

Description

technical field [0001] The invention relates to a method for manufacturing a facial mask, in particular to a method for preparing a dry nanofiber facial mask. Background technique [0002] Mask is one of the important cosmetics for facial skin care. Its forms mainly include mud paste type, tear-off type, jelly type, and wet tissue type. Among them, the wet tissue type mask is popular among women because of its portability and simple operation. favor. The wet tissue mask is made of non-woven fabric base material supplemented with nutrients and drugs, and is applied to the face. Using the short time covered on the face, the moisture and nutrients in the mask penetrate into the stratum corneum of the skin epidermis, making the skin smooth It is soft and elastic, so it is loved by many women. But now there are the following problems in the facial mask: 1. The facial mask is immersed in the nutrient solution, and the nutrient solution will inevitably drip during taking out or a...
