Abstract
The utility model 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 in 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 PU permeable formations bottom.PU permeable formations penetrate into Hair style base fabric, so that the upper surface of Hair style base fabric is formed partes villosa by polishing, 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, have good gas permeability；In addition, surface velvet, sense of touch, closer to corium, PU permeable formations make the dry and wet of PU breathable leathers wipe the physical indexs good stables such as color fastness, peel strength, hydrolysis 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 utility model is related to PU to remove from office field, and in particular to a kind of PU breathable leathers.
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 removes from office the air-locked defect of generally existing, manufactured dress ornament wearing comfort is poor；There are also at PU layers at present
Upper providing holes, in order to form the sense of touch of approximate corium, is still to need in PU layers of table to improve the PU breathable leathers of gas permeability
Face flocking, 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, villus 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 to be connected to, gas permeability is less desirable.
Invention content
The technical problem to be solved by the present invention is to provide a kind of PU breathable leathers, can solve existing PU breathable leathers needs
PU layers of wet method, PU layers of dry method and tapetum are set gradually in scrim surfaces, leads to complex process and gas permeability is undesirable asks
Topic.
The utility model 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, in the base fabric below the partes villosa
PU permeable formations are provided with, there be the osmosizing portion in the yarn hole for penetrating into base fabric PU permeable formations bottom.
The further scheme of the utility model is that the thickness of the PU permeable formations is the 10% ~ 25% of base fabric thickness.
The further scheme of the utility model is that the thickness of the partes villosa is the 5% ~ 10% of base fabric thickness.
The further scheme of the utility model is that the base fabric is using Hair style base fabric.
The utility model compared with prior art the advantages of be：
PU permeable formations penetrate into Hair style base fabric, so that the upper surface of Hair style base fabric is formed partes villosa by polishing, only
Need 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, tool
There is good gas permeability；In addition, surface velvet, sense of touch, closer to corium, PU permeable formations make with combining closely for Hair style base fabric
The dry and wet of PU breathable leathers wipes the physical indexs good stables such as color fastness, peel strength, hydrolysis, hence it is evident that better than common PU leather productions
Product.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The upper surface of a kind of PU breathable leathers as shown in Figure 1, including Hair style base fabric 1, the Hair style base fabric 1 is villus
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, and 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.
For 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 weight ratio of fat and DMF substantially 1:1 compares, and this programme is by PU resins and DMF according to 100:250 ~ 300 weight ratio into
Row further dilution is added auxiliary agent and obtains mixed liquor, and the auxiliary agent includes for improving 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 weight ratio is mixed, PU resins
With calcium according to 100:25 ~ 30 weight ratio is mixed；Then use osmosis process that mixed liquor is coated in Hair style base fabric 1
The upper PU layers for forming 0.4mm thickness infiltrate through 2 thickness of PU permeable formations in Hair style base fabric 1 in the PU layer as 0.3mm, cover and imitate
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 that not permeating in yarn, which has 1 thickness of Hair style base fabric of PU,；1 upper surface of Hair style base fabric is carried out again
Skin processing is ground, the surface layers PU is removed completely, and the thickness of PU permeable formations 2 is removed into 0.1mm, is reduced to 0.2mm, removing 0.1mm
During thick PU permeable formations 2, the Hair style base fabric 1 of top layer 0.1mm thickness is interrupted the partes villosa 4 for becoming 0.1mm thickness simultaneously；
It obtains 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
The PU breathable leathers of the 1.5mm thickness formed with the partes villosa 4 of PU permeable formations 2 and 0.1mm thickness in yarn hole.
