In such an embodiment, it is preferable that the plurality of ventilation holes are arranged in a regular manner, such as in a predetermined pattern, for the purpose of enhancing the aesthetic appearance.

Furthermore, the present invention also provides a method for manufacturing artificial leather, which can be applied to the manufacturing of the artificial leather, as shown in fig. 4, the method comprising the steps of:

s1: weaving by using a plurality of groups of warp yarns and weft yarns, wherein each group of warp yarns and weft yarns is woven into a single-layer structure, and each single-layer structure is formed by mutually weaving part of warp yarns and weft yarns of one layer with part of warp yarns and weft yarns of other one layer or more layers to form a plurality of connecting points;

s3: the base fabric is bonded to the resin layer to form the artificial leather, and specifically the base fabric can be bonded to the resin layer by calendering, casting, extruding, coating, dipping, or the like.

The artificial leather manufactured by the manufacturing method has various advantages of the artificial leather in the embodiments, and specific effects of the artificial leather can be seen from the above, and are not described again.

In practical applications, step S1 is preceded by a spinning step, in which the warp and weft yarns are formed and then woven (i.e., step S1, which may also be referred to as "weaving"). Of course, the warp and weft yarns may also be purchased directly.

In forming the artificial leather having a sanded structure, there is further included, between steps S1 and S3, the steps of:

s2: polishing one surface (namely one surface of the first surface layer, which is far away from the second surface layer) of the base cloth by adopting tools such as a grinding wheel, a file and the like so as to form the base cloth with a roughened structure on the surface; wherein at least one of the warp and weft of the single layer weave (i.e. the first surface layer) in which the sanded structure is located is selected from sea island filaments;

in this embodiment, step S3 specifically includes:

and (3) attaching the other surface (namely the surface of the second surface layer departing from the first surface layer) of the base cloth with the resin layer to form the artificial leather.

Through increasing the process of polishing, make the one side of base cloth have the structure of frosting (or become the fine hair structure), as above, can make the both sides of synthetic leather more comprehensively be close the visual effect and the feeling of genuine leather, more be favorable to the substitution of synthetic leather to genuine leather surface fabric, and can further improve the application scene of synthetic leather. Wherein, the degree of depth of polishing to first top layer the utility model discloses do not make the restriction, can go on as required.

In the existing single-layer tissue base cloth, if one surface of the base cloth needs to be polished, because the whole base cloth is only provided with one layer, certain areas are extremely easy to be polished excessively or even completely, the rejection rate is too high, and the quality is difficult to control; and is not easy to operate during sanding. And adopt the utility model discloses a base cloth with multilayer structure because the base cloth has multilayer structure, and the tie point that multilayer warp and gauze formed through the layer becomes a whole, and is insensitive to the volume of polishing on first top layer during polishing, grinds deeply a bit, grinds shallowly and can a bit, even polish thoroughly the individual layer tissue part in the outside when polishing, because the existence of other individual layer tissues in addition, the wholeness ability of base cloth still can the meet the demands, consequently, can improve the yield of synthetic leather greatly. Simultaneously, because above-mentioned advantage, the degree of difficulty when polishing to the base cloth requires to have reduced, can improve the production efficiency of synthetic leather.

Of course, before step S3, the base fabric after spinning, weaving or even polishing may be finished and then attached to the resin layer.

In addition, the artificial leather prepared by the preparation method provided by the utility model by respectively using different warp and weft materials is shown in the following table 1-table 4 as example 1-example 5; meanwhile, the existing single-layer weave artificial leather was also prepared, and the weft yarns were reinforced when the single-layer weave artificial leather was manufactured, as a comparative example. The comparative examples and examples 1-5 were then tested for mechanical properties before and after punching, respectively, and the results are shown in tables 1-4. Note that, in the table, with the extending direction of the artificial leather (including the single-layered artificial leather of the comparative example and the artificial leather having a multilayer structure of the present application) as the longitudinal direction and the direction perpendicular to the extending direction as the transverse direction, "left" and "right" respectively refer to both sides in the transverse direction, "middle" refers to the middle in the transverse direction, and the dimension N/3cm refers to the maximum stretching force that a sample of 3cm width can withstand.

TABLE 1

TABLE 3

TABLE 4

Can obviously see out by above-mentioned each table, the utility model discloses an artificial leather no matter before punching or after punching, its tensile and tear performance all compare the proportion and have very big improvement. And examples 1 to 5 only exemplify artificial leathers made of base fabrics having a double-layer structure, which already have such remarkable advantages in mechanical properties, it is conceivable that the mechanical properties of the artificial leathers are more excellent for base fabrics having a three-layer structure or more. Therefore, the base fabric with the multilayer structure solves the problems of large mechanical property loss and poor stability of the single-layer-structure artificial leather after punching through structural optimization, can replace the existing leather fabric product, and has good social benefit. Meanwhile, compared with a real leather fabric, the artificial leather with the multilayer structure has great advantages in material cost and can adapt to more application scenes.

The utility model also provides a vehicle, including vehicle seat, vehicle seat's surface fabric includes as above arbitrary embodiment the synthetic leather.
