The invention discloses a kind of PU breathable leathers, including Hair style base fabric, the upper surface of the Hair style base fabric is partes villosa, and PU permeable formations are provided with the Hair style base fabric below the partes villosa, and there be the osmosizing portion in the yarn hole for penetrating into Hair style base fabric the PU permeable formations bottom.The invention also discloses a kind of preparation method of PU breathable leathers.PU permeable formations are penetrated into Hair style base fabric, and the upper surface for making Hair style base fabric by polishing forms partes villosa, it is thus only necessary to and one layer PU layers, technique very simple, and also it is cost-effective；And PU permeable formations can not block Hair style base fabric completely, there is good gas permeability；In addition, surface velvet, sense of touch make the dry and wet of PU breathable leathers wipe the physical index good stables such as color fastness, peel strength, hydrolysis closer to corium, PU permeable formations with combining closely for Hair style base fabric, hence it is evident that remove from office product better than common PU.
Description
Technical field
The present invention relates to PU to remove from office field, and in particular to a kind of PU breathable leathers and preparation method.
Background technology
The limits throughput of natural leather, and the environmental consciousness of people is increasingly enhanced, and the market share of PU leather is higher and higher,
But traditional PU leather air-locked defects of generally existing, manufactured dress ornament wearing comfort are poor；Also there are some at PU layers at present
Upper providing holes is still to need in PU layers of table to improve the PU breathable leathers of gas permeability, but in order to form the sense of touch of approximate corium
Face flocking, its structure include at least PU layers of the wet method in scrim surfaces, and in PU layers of the dry method of wet method PU layer surfaces, fine hair is attached to
On dry method PU layers, one side technique is still more complicated, and on the other hand, the hole in PU layers of wet method and dry method PU layers often interlocks
Cause not connect, gas permeability is less desirable.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of PU breathable leathers and preparation method, can solve existing PU and breathe freely
Leather needs to set gradually PU layers of wet method, PU layers of dry method and tapetum in scrim surfaces, causes complex process and gas permeability to be paid no attention to
The problem of thinking.
The present invention is achieved through the following technical solutions：
A kind of PU breathable leathers, including base fabric, the upper surface of the base fabric are partes villosa, are set in the base fabric below the partes villosa
There are PU permeable formations, there be the osmosizing portion in the yarn hole for penetrating into base fabric the PU permeable formations bottom.
The further scheme of the present invention is that the thickness of the PU permeable formations is the 10% ~ 25% of base fabric thickness.
The further scheme of the present invention is that the thickness of the partes villosa is the 5% ~ 10% of base fabric thickness.
The further scheme of the present invention is that the base fabric is using Hair style base fabric.
A kind of preparation method of PU breathable leathers, comprises the following steps：
A. by PU resins and DMF according to 100:250 ~ 300 part by weight is mixed, and is added auxiliary agent and is obtained mixed liquor；
B. mixed liquor being coated in scrim surfaces, a part for mixed liquor, which is penetrated into, forms PU top layers and PU permeable formations in base fabric, with
And from the osmosizing portion in the yarn hole that PU permeable formation bottom percolations enter base fabric, obtain semi-finished product；
C. semi-finished product are carried out with mill skin, removes PU top layers and partial PU permeable formations, base fabric upper surface is formed partes villosa.
The further scheme of the present invention is that the auxiliary agent includes calcium and wood powder, and wherein PU resins and calcium is according to 100:80~
100 part by weight is mixed, and PU resins are with calcium according to 100:25 ~ 30 part by weight is mixed.
The further scheme of the present invention is that the thickness of the PU permeable formations is the 10% ~ 25% of base fabric thickness.
The further scheme of the present invention is that the thickness of the partes villosa is the 5% ~ 10% of base fabric thickness.
The further scheme of the present invention is that the base fabric is using Hair style base fabric.
The present invention compared with prior art the advantages of be：
PU permeable formations are penetrated into Hair style base fabric, and the upper surface for making Hair style base fabric by polishing forms partes villosa, it is thus only necessary to
One layer PU layers, technique very simple, and also it is cost-effective；And PU permeable formations can not block Hair style base fabric completely, have good
Good gas permeability；In addition, surface velvet, sense of touch make PU saturating closer to corium, PU permeable formations with combining closely for Hair style base fabric
The dry and wet of gas leather wipes the physical index good stables such as color fastness, peel strength, hydrolysis, hence it is evident that removes from office product better than common PU.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
A kind of PU breathable leathers as shown in Figure 1, including Hair style base fabric 1, the upper surface of the Hair style base fabric 1 is fine hair
Portion 4, is provided with PU permeable formations 2 in the Hair style base fabric 1 of the lower section of the partes villosa 4,2 bottom of PU permeable formations, which also has, to be penetrated into
Entering the osmosizing portion 3 in the yarn hole of Hair style base fabric 1, the thickness of the PU permeable formations 2 is the 10% ~ 25% of 1 thickness of Hair style base fabric,
The thickness of the partes villosa 4 is the 5% ~ 10% of 1 thickness of Hair style base fabric.
Exemplified by making the PU breathable leathers of 1.5mm thickness, the Hair style base fabric 1 of 1.5mm thickness is selected, with PU trees in traditional handicraft
The part by weight of fat and DMF substantially 1:1 compares, and this programme is by PU resins and DMF according to 100:250 ~ 300 part by weight into
Row further dilution, adds auxiliary agent and obtains mixed liquor, the auxiliary agent is including being used to improve the calcium of PU resin penetration power and making PU trees
The wood powder of air hole is formed in fat, wherein PU resins and calcium is according to 100:80 ~ 100 part by weight is mixed, PU resins
With calcium according to 100:25 ~ 30 part by weight is mixed；Then mixed liquor is coated in by Hair style base fabric 1 using osmosis process
The PU layers of upper formation 0.4mm thickness, 2 thickness of PU permeable formations infiltrated through in Hair style base fabric 1 in the PU layers is 0.3mm, and covering is imitative
The PU skin depths on 1 surface of cashmere base fabric are 0.1mm, and 2 bottom of PU permeable formations, which also has, to be penetrated into the yarn hole of Hair style base fabric 1
Osmosizing portion 3, it is 1.2mm not permeate 1 thickness of Hair style base fabric for having PU in yarn；1 upper surface of Hair style base fabric is carried out again
Skin processing is ground, removes PU top layers completely, and the thickness of PU permeable formations 2 is removed into 0.1mm, 0.2mm is reduced to, is removing 0.1mm
During thick PU permeable formations 2, the Hair style base fabric 1 of the superiors 0.1mm thickness is interrupted the partes villosa 4 for becoming 0.1mm thickness at the same time；
Obtain not permeating the Hair style base fabric 1 for having PU in the yarn by 1.2mm thickness, the yarn for infiltrating through Hair style base fabric 1 of 0.2mm thickness
