Description
Technical field
The present invention relates to 3D printing technique field, is specially a kind of 3D printing method of nanofiber dry type facial mask.
Background technology
Facial mask is a kind of important skin care item, to realize that the moisturizing moisturizing of skin of face, whitening, anti-oxidant, grease are put down
Weighing apparatus.Its form mainly has four kinds of mud cream type, tear-pull, frozen glue, wet tissue patch etc..Relatively common is to be encapsulated, soaked with sack
Non-woven fabrics patch in nutrient solution.The application for a patent for invention that last decade is related to facial mask increases year by year, has obtained the pact of mandate
Account for the 20% of total amount.In related patents, the citation form of facial mask does not have too many change, mainly using unlike material
One or more layers non-woven fabrics basement membrane absorb different nutrient solution.Change of the applicant concern is primarily with nutrient composition and base material
Change, the change of focus on facial mask shape on a small quantity, fold etc..
People are being mainly reflected in for the use of two using run into during patch facial mask the problem of.First, commercialization facial mask
Plane, single shape, it is impossible to be bonded the multifarious face of user, the comfort used is poor；Second, immersion facial mask
Liquid is excessive, packaging material wastes, and inconvenience is produced during taking.
In order to improve patch facial mask comforts of use, there are some patent applications, as being referred to as " three dimensional face mask "
CN200910131298.9, there is provided facial mask be made of the symmetrical right side sheet material of shape and left side sheet material.First in right side piece
On the medial surface for the scope that material and left side sheet material include the front end opposite with facial center line, thermoplastic binder material is applied,
Make right side sheet material and the contact of left side sheet material respective medial surface and overlapping, then in front end except the part opposite with nostril
Scope beyond the part opposite with mouth is heated, and right side sheet material and left side sheet material are linked together.Then, right side is made
The direction expansion that scope in sheet material and the respective peripheral part of left side sheet material in addition to front end is left towards each other, so that vertical
Honorable film is in along whole facial three-dimensional shape.
And for example, patent application " manufacture method of three dimensional face mask " CN201210367087.7, being related to content includes：Bending step
Suddenly, binding material will be contained on the whole thickness direction of whole sheet material or at least on the whole thickness direction of Rack part
Bodies or at least one surface of sheet material sheet material containing binding material on the whole or at least on Rack part
Body, gives doubling using a surface in the center of Rack part as inner side；Forming step, carries out according to following line of cut
Cutting, i.e., making the front end opposite with facial center line of bodies in the state of being included in Rack part, front end
Portion and the part opposite with facial surroundings are the shape that continuous line of cut and line of cut are in integrally towards outside protrusion, then with
Rack bonds the scope in front end in addition to the part opposite with nostril and mouth.Make by simple structure
Facial mask is in the three-dimensional concavo-convex three-dimensional shape along face, and easily can be binded facial mask on whole face.
For another example, patent application " multilayer stereo facial mask and its manufacture method " CN201510094262.3, there is provided Yi Zhongduo
Level three dimensional face mask, including the smooth inner layer close to face and the smooth outer layer away from face, and positioned at smooth inner layer peace
The material middle level of sliding outer layer, facial mask have splendid ductility, form the facial mask that can completely apply on the face.Patent application
CN200980106414.X (PCT/JP2009/052983), substantially upside phase of the facial mask being related in the facial contours with facial mask
To position on there is grips, on the horizontal direction of face, mountain folding part and paddy folding part alternate folding, then again with the folding
Line is substantially orthogonal folding, and above-mentioned grips protrudes from folded into can hold ductile foldable structure.Its principal right will
Ask for：A kind of facial mask, the shape of face can be covered by being formed, and impregnate liquid cosmetic preparation in substrate sheet, and when use is extendable
Fold facial mask, it is characterised in that the facial mask has grips on the opposite position in substantially upside with facial contours, in face
Horizontal direction on, mountain folding part and paddy folding part alternate folding, cross folding, above-mentioned grips protrude from folding to the fold line of formation again
The outside of folded facial mask.
The present invention provides a kind of 3D for a kind of " 3D printing facial mask and its preparation process " CN201510420156.X summaries
The preparation process of facial mask is printed, is comprised the following steps：Under conditions of Sterile vacuum, according to human facial profile, beaten using 3D
Print machine is sequentially overlapped printing collagen gel and facial mask liquid, obtains 3D printing facial mask.Process needs not move through pyroprocess, can
To preserve the active ingredient of facial mask liquid., can be with addition, collagen gel under vacuum, forms porous facial mask stent
Farthest absorption facial mask liquid.Although the patent application refers to 3D printing technique, actually a kind of imagination is simultaneously infeasible, because
The material used for current 3D printer is all thermoplastic material, is not appropriate for the manufacture of facial mask.
A kind of " preparation method precisely repaired with nursing facial mask " CN201610047449.2, is related to one kind and precisely repairs
