The specific embodiment

In order to describe structure of the present utility model and characteristics in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.

As shown in Figure 1 and Figure 2, the synthetic leather 10 that is provided for the utility model first preferred embodiment, it includes a base material 12, a following layer 14, a background layer 16 and a coating layer 18, wherein coating layer 18, background layer 16 stack on the fid (not shown) in advance in regular turn with following layer 14, be transferred to base material 12 then, form the synthetic leather 10 of present embodiment, wherein:

Base material 12 can be by nonwoven, weave cotton cloth, fiber cloth, coated split leather, polyurethane (PU) or polyvinyl chloride (PVC) are made, present embodiment is example with the nonwoven, wherein the end face of nonwoven constitutes the surface 121 of base material 12, provides synthetic leather 10 whole better tensile strength with this.

Following layer 14 solidify to form for coating base material 12 surfaces 121 with the resin viscose, and present embodiment is an example with polyurethanes (polyurethane), and following layer 14 is used to strengthen the bonding effect of base material 12 and background layer 16, after the structure of background layer 16 is described in.

Background layer 16 is the thin type lamellar body that a surface has concave convex texture, and it can be formed by PU resin or high solid resin solidification in the present embodiment.Background layer 16 has a bottom surface 161 and an end face 162, and wherein, fit with following layer 14 gluings and with base material 12 surfaces 121 in bottom surface 161, and in addition, end face 162 is staggered to form by a plurality of protuberance 162a and a plurality of recess 162b.

Coating layer 18 is in the present embodiment for adopting polyurethane (PU) to make, as shown in Figure 3, coating layer 18 is covered in each protuberance 162a of background layer 16 end faces 162 and the thin layer that each recess 162b is solidify to form for coating, its thickness is thinner than background layer 16, present embodiment utilizes cloth wheel (not shown) that coating layer 18 is polished milled processed, till outside the protuberance 162a of background layer 16 is revealed in, as shown in Figure 1, so, irradiation by light, each exposed protuberance 162a will be rendered as different color and lusters respectively with the interior residual coating layer 18 of recess 162b, promptly, each protuberance 162a constitutes the bright rays of synthetic leather 10, and the coating layer 18 in each recess 162b constitutes the dark line of synthetic leather 10.

Again as shown in Figure 4, the synthetic leather 20 that is provided for the utility model second preferred embodiment, the present embodiment and first preferred embodiment have roughly the same structure, promptly include a base material 22, a following layer 24, a background layer 26 and a coating layer 28, the difference place only is the structure of base material 22, wherein, the base material 12 of first preferred embodiment is the single layer structure body, and the base material 22 of present embodiment is the two-layer structure body, and base material 22 includes a substrate 221 and a top layer 222, wherein:

Substrate 221 can be by nonwoven, weave cotton cloth, fiber cloth, coated split leather, PU or PVC are made, and present embodiment is example with the nonwoven, and the nonwoven end face constitutes the end face 221a of substrate 221, and thus, substrate 221 can provide synthetic leather 20 whole better tensile strength.

Top layer 222 solidify to form in substrate 221 end face 221a for PU is resin-coated.By top layer 222 is set, can make synthetic leather 20 have more elasticity and solid sense, and the PU material top layer 222 of making can provide the shock-proof effect of synthetic leather 20 softnesses.

Certainly, the following

layer

14,24 of aforementioned two embodiment also can save, the synthetic skin 30 that the utility model the 3rd preferred embodiment is as shown in Figure 5 provided, and the synthetic skin 40 that the utility model the 4th preferred embodiment shown in Figure 6 is provided promptly is respectively the embodiment that saves following layer.The utility model the 3rd and the 4th preferred embodiment are the characteristic of sticky shape when utilizing the

background layer

32,42 on the fid (not shown) not solidify fully respectively, itself and

base material

34,44 are carried out the pressing binding, drying is solidified then, makes

background layer

32,42 combine with the surface 341,441 of

base material

34,44.

More than be explanation to synthetic leather of the present utility model.The utility model utilization is covered in the coating layer as thin as a wafer on synthetic leather surface, and the design of the jog of background layer, make coating layer after grinding through the polishing of cloth wheel, utilize the light and shade contrast of coating layer and background layer, build synthetic leather with the staggered lines outward appearance of light and shade, make when synthetic leather is applied to the making of back segment finished product, can be product and increase additional texture.

Need to prove in addition, the formation method of each structure sheaf of base material top of aforementioned two embodiment has more than to be limited to and stacks on the mode that then is transferred to base material on the fid more in advance, in other words, also can take modes such as printing or screen painting to make, in addition, in the process of printing, more can increase the colorful property of light and shade lines, can reach the purpose of this utility model so equally by adding different colorants.

The above only is several preferable possible embodiments of the present utility model, uses the equivalent structure variation that the utility model specification and claims are done such as, all should be included in the scope of patent protection of the present utility model.
