Abstract
The utility model provides a gas permeability dermatine, including the basic unit, basic unit's lower extreme sees through alite paste fixedly connected with non -woven fabrics layer, fixed the covering in basic unit upper end has the PU rete, evenly set up the micropore of a plurality of mutual correspondences on basic unit, non -woven fabrics layer, the PU rete respectively, little porosity is 190, 000 / square metre - 220, 000 / square metre, the utility model discloses a gas permeability dermatine, simple structure, it has evenly seted up the many micropores of nano -scale on the dermatine, be that the gas permeability of dermatine improves with the hydroscopicity greatly.
Description
Technical field
The utility model relates to weaving materials, specifically, relates to a kind of gas permeability dermatine.
Background technology
Dermatine is also imitation leather or sizing material, is the general name of the artificial materials such as PVC and PU.It is on woven fabric base or nonwoven fabric base, formed by the foaming such as PVC and PU of various different formulations or overlay film processing and fabricating, can require be processed into according to varying strength, abrasion resistance, cold-resistant degree and color, gloss, floral designs etc., have that designs and varieties are various, water resistance good, not care about one's appearance is neat, utilization rate is high cheap relative to corium with price.
But synthetic leather page possesses its inevitable shortcoming, be exactly that its gas permeability and water absorption cannot reach requirement.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provides a kind of gas permeability dermatine.
Gas permeability dermatine of the present utility model, comprises basic unit;
Described basic unit lower end is fixedly connected with nonwoven layer through alite paste, and described basic unit upper end is fixedly covered with PU rete;
Described basic unit, nonwoven layer, PU rete evenly offer respectively the micropore of some mutual correspondences;
Described pore density is 190,000/square metre-22 ten thousand/square metre.
Further, described nonwoven layer thickness is 0.3cm-0.5cm.
Further, described basic unit is aramid fiber layer, and its thickness is 0.8cm-1cm.
Wherein:
Described basic unit, nonwoven layer, PU rete evenly offer respectively the micropore of some mutual correspondences;
Described pore density is 190,000/square metre-22 ten thousand/square metre; Such setting, makes micropore can not affect the physical index of synthetic leather and synthetic leather gas permeability and water imbibition are improved greatly.
Gas permeability dermatine of the present utility model, structure is simple, and it evenly offers nano level many micropores on dermatine, is that gas permeability and the water imbibition of dermatine improves greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of gas permeability dermatine of the present utility model;
Mark in figure: 1 be PU coating layer, 2 be aramid fiber layer, 3 for nonwoven layer.
Detailed description of the invention
Below with reference to the accompanying drawings embodiment of the present utility model is described.The element described in an accompanying drawing of the present utility model or a kind of embodiment and feature can combine with the element shown in one or more other accompanying drawings or embodiment and feature.It should be noted that for purposes of clarity, accompanying drawing and eliminate expression and the description of parts that have nothing to do with the utility model, known to persons of ordinary skill in the art or process in illustrating.
Below in conjunction with accompanying drawing, the utility model is described further.
Gas permeability dermatine of the present utility model, comprises basic unit 2 as shown in Figure 1;
Described basic unit 2 lower end is fixedly connected with nonwoven layer 3 through alite paste, and described basic unit 2 upper end is fixedly covered with PU rete 1;
Described basic unit 2, nonwoven layer 3, PU rete 1 evenly offer respectively the micropore of some mutual correspondences;
Described pore density is 200,000/square metre.
Described nonwoven layer 3 thickness is 0.3cm.
By detecting, gas permeability dermatine Air permenbility of the present utility model is more than 1.5, and permeable amount is about 4.
Described basic unit 2 is aramid fiber layer, and its thickness is 0.8cm.Gas permeability dermatine of the present utility model, structure is simple, and it evenly offers nano level many micropores on dermatine, is that the gas permeability of dermatine improves greatly.
Although described the utility model and advantage thereof in detail, be to be understood that and can have carried out various change when not exceeding the spirit and scope of the present utility model limited by appended claim, substituting and conversion.And the scope of the application is not limited only to the specific embodiment of process, equipment, means, method and step described by description.One of ordinary skilled in the art will readily appreciate that from disclosure of the present utility model, can use perform the function substantially identical with corresponding embodiment described herein or obtain and its substantially identical result, existing and that will be developed in the future process, equipment, means, method or step according to the utility model.Therefore, appended claim is intended to comprise such process, equipment, means, method or step in their scope.
