Problems solved by technology

[0004] Popular facial masks on the market are usually based on spunlace nonwovens, and the publication number is the patent application of CN 108179546 A, a kind of seaweed fiber nonwoven fabric and its production process and application of high-pressure non-aqueous solvent liquid flow for fiber winding In conclusion, the machine used to process non-woven fabrics in this method is inconvenient to process other non-woven fabrics. Second, the ions in the non-aqueous solution will accelerate the oxidation of the surface of the machine, resulting in shortened machine life, and non-woven fabrics can only absorb high moisture. Does not produce gel like traditional face masks
The patent application with the publication number CN 109577003 A, seaweed fiber facial mask base fabric and its preparation method, is that carboxymethyl cellulose fiber and calcium alginate fiber are blended into nonwoven fabric and then put into sodium alginate solution for modification. The fiber can only maintain the fibrous shape in dilute solution, and the sodium alginate solution has a high viscosity, which is not conducive to the modification operation, and the hydrogel mask made by this method has serious adhesion and high brittleness, which is not conducive to mask packaging

Abstract

The invention discloses a hydrogel type seaweed fiber nonwoven fabric and its preparation method and application, which belongs to the technical field of nonwoven fabric production and is prepared from seaweed fiber, skeleton fiber and modified solvent, wherein the seaweed fiber and The mass ratio between the skeleton fibers is 30~80:20~70. The hydrogel type seaweed fiber nonwoven fabric of the present invention is soft in texture and hydrogel, and can be applied on the skin to achieve the effect of moisturizing and whitening; in addition, the nonwoven fabric changes the situation that the traditional facial mask base fabric can only be used as a medium, and is easy to carry , easy to save.

Description

technical field [0001] The invention discloses a hydrogel-type seaweed fiber nonwoven fabric, a preparation method and application thereof, and belongs to the technical field of nonwoven fabric production. Background technique [0002] As a new type of functional fiber, seaweed fiber is a fiber formed by extracting alginic acid from seaweed as a raw material, making a solution with a certain concentration, extruding through a spinneret and undergoing an ion exchange reaction with metal ions in a coagulation bath. Seaweed fiber has good water absorption, biocompatibility, gelation, far-infrared effect, heavy metal adsorption, etc. [0003] As people have higher and higher requirements for the quality of facial masks, the existing facial mask base cloth has a thick texture and poor air permeability due to the addition of a large amount of essence; it also causes waste of resources because it only acts as a medium. Therefore, people are looking for a mask base cloth that can b...
