Description

A kind of preparation method of antibacterial facial mask fabric

Technical field

The present invention relates to skincare product preparation technical fields, and in particular to a kind of preparation method of antibacterial facial mask fabric.

Background technique

Facial mask is one of the important composition of the daily skin nursing of women.Its principle is exactly to utilize to be covered on the of short duration of face Time is temporarily isolating extraneous air and pollution, improves skin temperature, expand the pore of skin, promote sweat gland secretion with newly Old metabolism rises the oxygen content of skin, is conducive to skin and excludes the product of epidermal cell metabolism and the grease type of accumulation Substance, the moisture in facial mask go deep into the cuticula of epidermis, and skin is made to become soft, and light is flexible naturally for skin.With society It continues to develop, the pursuit of beauty is continuously improved in people, and the demand of facial mask is continuously increased, and the requirement of people opposite film properties is also got over Come higher.

The form of facial mask mainly has mud paste type, tear-pull, gel-type, four kinds of sheet type currently on the market.Wherein, sheet type Face mask substrate material mainly has non-woven fabrics facial mask, silk mask, organic pure cotton facial mask, paper pulp facial mask, Biofibre facial mask, lace facial mask Deng.Sheet type facial mask because be easy to save carrying, surface application it is simple it is easy to get started, water content is high, with it is rear free of cleaning the advantages that, by women The favor of user is sure to occupy first in the market retention of existing facial mask category.

Existing facial mask is usually to be mixed by polyester fiber and viscose rayon substantially, and this fiber has certain Absorbability can adsorb more moisture or Essence.But existing face mask substrate material has the following deficiencies: patch skin performance one As, after on the face, the one side of facial mask and skin attachement, nutrient solution can be absorbed by the skin mask sheet, but facial mask is backwards The one side of skin, nutrient solution distribute more serious, reduce the using effect of nutrient solution.Currently, domestic enterprise is directed to face mask substrate material Research, development and production technique mainly based on spunlace non-woven method, water absorption rate, rebound degree, property rich in color etc. need It further increases.Such as there is the spy of high liquid-loading capacity using the mask substrate of the double-deck spun lacing method preparation in patent CN204875072U Point, but its double-deck non-woven constructions determines its lower resilience and mechanical strength.In addition, facial mask can not be kept away in process of production The meeting exempted from introduces a certain number of microorganisms by many aspects such as raw material, ingredient, packaging materials, in addition in facial mask essence Inherently protein rich in, polysaccharide, oligosaccharides, vitamin etc. easily cause the ingredient of microbial reproduction, this is easy to draw Bacterium mass propagation in facial mask is played, so as to cause the rotten of facial mask.

Therefore, it is good to prepare a kind of absorption property, patch skin is good, it can be improved the utilization rate of nutrient solution, soft comfortable, no The facial mask fabric of skin can be injured, there is important theory significance and application value.

Summary of the invention

Present invention mainly solves the technical issues of, inevitably pass through original in process of production for current facial mask The many aspects such as material, ingredient, packaging material introduce a certain number of microorganisms, in addition in facial mask essence inherently containing rich Rich protein, polysaccharide, oligosaccharides, vitamin etc. easily causes the ingredient of microbial reproduction, easily causes bacterium in facial mask fabric Prolific defect provides a kind of preparation method of antibacterial facial mask fabric.
