Description
Technical field
The invention belongs to technical field of skin care, and in particular to a kind of Biofibre facial mask base fabric also relates to one kind
Using the Biofibre facial mask of the mask substrate.
Background technology
Facial mask be apply or spread on human facial skin surface, taken off after a period of time from, clean or retain, play concentration shield
The skin care item of reason or cleaning action；, mainly there are whitening, moisturizing, promotion cycle, tensioning the skin etc. in the effect of facial mask.As people disappear
Take the abundant and maturation of theory, facial mask industry obtains rapid growth.
Facial mask can be divided into no base fabric type and base fabric type according to occupation mode.Currently, 70% or more facial mask available on the market
It is base fabric type, this kind of facial mask is to be aided with the nutrient solution of different-effect using fiber base cloth as carrier, improves skin for nutritional ingredient
Infiltration rate and uptake, and rapidly improve skin care effect.Nutrient solution main component is to extract from plant, animal or day
The active ingredients such as right mineral are concentrated using corresponding technique and technology refinement, and major function is whitening, moisturizing and provides flesh
The required nutrition of skin and moisture, delay skin aging.
For base fabric type facial mask mostly using non-woven cloth as base fabric, processing technology has hot rolling, spunbond, spun lacing, melt-blown etc., wherein with water
Spunlaced nonwoven application is most because its feel is soft, quality can people, porosity is high, moisture retention is good, facial mask can be made to carry big
The nutrient solution of amount ensures that skin fully absorbs.Commercially available non-woven mask substrate mainly with cotton fiber, viscose rayon, copper ammonia fiber,
Wood pulp cellulose is primary raw material, and a small number of products are using cocoon fiber, alginate fibre etc..
With the development of facial mask industry, mask substrate develops from single carrier function towards functionalization direction, and base fabric is fine
The the performance of dimension the good more can promote absorption of nutrient ingredients, and the effect of nutrient solution can more play, and skin circulation also can and then improve.But
It is that existing cotton fiber, viscose rayon, copper ammonia fiber base fabric etc. are developed by clothing fabric, are needed in production process
Using a large amount of chemical reagent (such as adhesive), substantially remained in facial mask more；And the pure biological fiber such as tencel fiber exists
It is also required to that a large amount of anticorrosive additive is added when use, the poor biocompatibility of these substances easily causes skin sensitivity, thorn
Pain and redness, contact skin, which is used for a long time, so that skin is damaged.
Invention content
The object of the present invention is to provide a kind of Biofibre facial mask base fabrics.
Second object of the present invention is to provide a kind of Biofibre facial mask using above-mentioned mask substrate.
To achieve the goals above, the technical solution adopted in the present invention is：
A kind of Biofibre facial mask base fabric, is prepared by method comprising the following steps：
1) polylactic acid is dissolved in chloroform, the spinning solution that mass concentration is 20%-25% is made；Using the spinning solution
Electrostatic spinning is carried out, acid fiber by polylactic felt is obtained；
2) chitosan solution for being made that mass concentration is 2.0%-2.5% in acetic acid aqueous solution is dissolved chitosan in, after
It is 0.2-0.3 according to the mass ratio of polyvinyl alcohol and chitosan:Polyvinyl alcohol is added in 1 ratio, and it is molten to be heated to 65-70 DEG C of stirring
Solution, obtains maceration extract；
Dipping is modified：Acid fiber by polylactic felt obtained by step 1) is immersed in the maceration extract, negative pressure deaeration 10-20s, is taken out
Surplus liquid and drying are squeezed out afterwards, obtain composite fibrofelt；
3) composite fibrofelt obtained by step 2) is subjected to spun lacing reinforcing at room temperature, it is 0.35-0.45mm, face to make its thickness
Density is 30-40g/m2To get.
In step 1), the parameter of the electrostatic spinning is：Filament mouth be No. 6 or No. 8 syringe needles, spinning voltage 15-25kV,
Spinning pole span is 10-15cm, and spinning flow velocity is 0.2-0.5ml/h.
In step 2), the mass concentration of acetic acid is 5%-10% in the acetic acid aqueous solution.
In step 2), it is at least once to impregnate modified number so that composite fibrofelt is relative to poly- breast obtained by step 2)
The weightening of sour fibrofelt is in 15%-20%.
In step 2), the temperature of the drying is 60-65 DEG C, drying time 12-24h.
In step 2), it refers to carrying out jam through roll to squeeze out surplus liquid, and the pick-up of each jam is 70%-80%.
In step 3), the spun lacing pressure that the spun lacing is reinforced is 15-20bar, a diameter of 0.08- of liquid drugs injection hole exits
0.12mm。
A kind of Biofibre facial mask using above-mentioned Biofibre facial mask base fabric.
In the Biofibre facial mask base fabric of the present invention, the macromolecular structure of chitosan makes it have antibacterial mite-removing, anti-inflammatory
Purulence relieves pain, removes scar, reducing wound bed fluid precipitation and conducive to excellent biocompatibilities such as wound site healings.But due to
The deliquescent limitation of chitosan itself, it is difficult to find suitable spin solvent, the spinning difficulty of chitosan itself is larger；It is pure simultaneously
Chitin fiber mechanical property it is poor, and higher price is not suitable for being directly used as facial mask basic.The biological fiber face of the present invention
Film base fabric utilizes the good processing performance of polylactic acid and polylactic acid using the acid fiber by polylactic obtained by electrostatic spinning as core material
Fiber excellent mechanical property and dimensional stability make it as timbering material, composite material are made to have excellent processing performance
And mechanical property；It is modified by impregnating so that polylactic acid fiber surface adheres to the mixed coating of chitosan and polyvinyl alcohol, gained
In composite material, chitosan contacts with human skin as face layer, can give full play to its biocompatibility and antibiotic property；On a small quantity
Polyvinyl alcohol and chitosan blend, the film forming of chitosan and the hydrophily of chitosan film layer can be further increased, to carry
High mask substrate holds liquid energy power；The reinforcing of fibrofelt is carried out by spun lacing method, gained mask substrate is soft, drapability
It is good,
The Biofibre facial mask base fabric of the present invention, is mainly prepared by chitosan and polylactic acid, chitosan and polylactic acid
It is biology base macromolecular material, good biocompatibility, gained mask substrate need not add additional chemical preservative, with
Human skin is in contact, and not will produce allergy, infection and red and swollen reaction, utilize instead the had antibacterial of chitosan face layer, anti-inflammatory,
The performance of analgesic promotes facial microtrauma healing；Mechanical property is good, there is preferable ultimate strength under dry state and hygrometric state,
Easy to process and use；It is strong to hold liquid energy power, more nutrient solutions can be carried so that the nutritional ingredient of nutrient solution can be more rapid
By percutaneous absorption；Good permeability, does not influence the eupnea of face skin, and comfort is high.In addition, the mask substrate master of the present invention
It is chitosan and polylactic acid to want ingredient, has good biodegradability will not be to ring as used disposable mask substrate
Border has an impact.
