Title:
UNIDIRECTIONAL WATER-GUIDING FACIAL MASK BASE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/062830
Kind Code:
A1
Abstract:
A unidirectional water-guiding facial mask base material, having a three-layer structure. The upper layer is a hydrophobic modified polyester fiber, the middle layer is a chitosan modified polyvinyl alcohol fiber, and the lower layer is a viscose fiber. After carding and web formation of the hydrophobic modified polyester fiber, the chitosan modified polyvinyl alcohol fiber, and the viscose fiber, hydroentanglement and reinforcement is performed to obtain the present unidirectional water-guiding facial mask base material. The three fiber layers of different materials are compounded, so that the obtained mask base material is capable of unidirectional vertical water-guiding. After the mask absorbs nutritional essence, the nutritional essence may be vertically transferred in a direction from top to bottom, so that the absorption efficiency of the nutritional essence is maximized and no nutritional essence is wasted. The surface density of each fiber layer and the angle of compounding, and cooperative effects of the three fiber layers of upper, middle, and lower layer, allow the obtained facial mask base material to have excellent overall performance, unidirectional water-guiding performance, excellent water absorption and water retention performance, and good air permeability and moisture permeability, so that sufficient absorption of the nutritional essence by facial skin is ensured, and the facial mask is comfortable and soft in texture.
