Brief description of the drawings
Fig. 1 is the schematic diagram of the vamp sole of cack of the present invention；
Fig. 2 is the cack structural representation of the present invention；
Embodiment
In order that it will be apparent to those skilled in that legibly understand the present invention, it is right in conjunction with the drawings and specific embodiments
The present invention is described in detail.
As shown in Figure 1-2, cack of the invention includes sole 1 and vamp 2, and the vamp includes forefoot portion and heel
Part, the heel portion are divided into symmetrical two pieces (22,23), and every piece of antetheca is connected as a single entity with forefoot portion, after two pieces
Wall region is superposed, and the fastener 25 by being arranged on rear wall is closed together.The fastener 25 is preferably viscous
Button.For the cack of the present invention compared with existing shoes, its main distinction is that the heel portion of vamp 2 is stacked by thread gluing
Together, it can be opened and closed, therefore very convenient when worn off to baby, can be with one-handed performance.When infant's foot compared with
Hour, overlay area can be increased, so that shoes are close to the heel of baby；After infant's foot is grown up, it can reduce stacked
Region, so as to expand the capacity of shoes.It possesses with baby development and the function of dilatation, and usage time interval is longer, practicality
It is stronger.
In order that cack is more firm, dress is more comfortable, the present invention additionally uses new technique --- 3D printing method is come
Make cack.The 3D printing method mainly includes following seven steps：(1) three-dimensional software design vamp 2 and the mould of sole 1 are utilized
Type, the heel portion of wherein vamp 2 are divided into two pieces (22,23), and every piece of antetheca is connected as a single entity with forefoot portion, two pieces of rear wall
Region is superposed when heel portion closes, and overlay area is provided with fastening area；(2) nexine vamp is printed；(3) will
Thread gluing is fixed to fastening area；(4) outer layer vamp is printed so that outer layer vamp covers the fringe region of thread gluing；(5) in printing
Layer sole；(6) shoe upper edge 21 is fixed to the region of nexine sole edge 11；(7) outer shoe is printed.Wherein, step (2)-
(4) operation order with step (5) can be changed, and can also carry out simultaneously.According to client's needs, when printing outer layer vamp,
In the printout surface three-dimensional pattern of vamp 2；When printing outer shoe, the anti-skidding Le bar of 3 D stereo is printed in sole surface 1
Or 3 D stereo non-slip patterns.Preferably, the nexine vamp and nexine sole are printed upon soft moisture-wicking textile surface, baby's
Foot is in contact with soft moisture-wicking textile, and dress is more comfortable.
According to the difference of vamp 2 and sole 1 to material pliability and hardness, present invention also offers a kind of brand-new baby
Footwear printed material.Wherein, nexine vamp, outer layer vamp and nexine sole are mainly made of following material：PLA 50~
67 parts, 20~38 parts of bamboo fibre, 3~5.6 parts of glycidyl trimethylammonium chloride, β-TiO20.1~3 part, aromatic series it is anti-oxidant
0.1~2 part of agent, 0.1~2 part of acid amides class lubricating oil, 0.1~1 part of Nano Silver, 0.1~3 part of silane coupler, 0~4 part of pigment.
Its pliability is good, gas permeability is high, and foot is contacted more comfortably, also with antibacterial function.The outer shoe utilizes carbon
Fiber substituted for part bamboo fibre, and its gas permeability reduces, the comfort level reduction with skin contact, but its wearability and hardness are purer
Bamboo fibre is high.In the present invention, outer shoe is mainly using 50~67 parts of PLA, 15~28 parts of bamboo fibre, carbon fiber 5~10
Part, 3~5.6 parts of glycidyl trimethylammonium chloride, β-TiO20.1~3 part, 0.1~2 part of aromatic series antioxidant, amide-type
0~4 part of 0.1~2 part of lubricating oil, 0.1~1 part of Nano Silver, 0.1~3 part of silane coupler, pigment printing form.In order that footwear
The flexibility and hardness of face and sole meet baby's needs comfortable and easy to wear, and the thickness of vamp and nexine sole is preferably defined 0.5
~3mm, the thickness of outer shoe are preferably defined in 1.5~10mm.
