Abstract

The utility model discloses two-tone embossed leather which comprises a base cloth layer, a polyurethane foam layer covering the base cloth layer, and a crazy-horse resin allochroic layer applied on the polyurethane foam layer; the upper surface of the two-tone leather is rugged and forms a plurality of crown parts and a plurality of channel parts, and the surfaces of each crown part is coated with a layer of roller coat. Compared with the prior art, the two-tone leather of the utility model has stronger three-dimensional effect and stronger two-tone and allochroic effects.

Description

Embossed two-colour leather

Technical field

The utility model relates to a kind of PU synthetic leather, the embossed two-colour leather that particularly a kind of third dimension is strong, double-colored, color changeable effect is good.

Background technology

The PU synthetic leather generally includes base cloth layer (also claiming cloth matter base material), be coated in wet method Base glue-line (polyurethane coating foaming layer) on the base cloth layer, be coated in the resin surface layer on wet method Base glue-line surface.

In the prior art; often also will carry out embossed technology to the synthetic leather that has applied the resin surface layer handles; make the synthetic leather surface; also we can say and make the surface of above-mentioned resin surface layer become uneven; the leather surface has formed a plurality of bizets and ditch portion; on visual effect; there are certain difference in the color of bizet and ditch portion and gloss; because ditch portion place's resin bed is extruded, bizet place resin bed protuberance, thereby ditch portion is of light color, gloss is a little bit poorer slightly; the bizet color is dark; reflecting feel is better slightly, and two-color effect is arranged from visually, therefore claims bicolor leather again.

But the two-color effect of present PU bicolor leather and not obvious (mainly be because third dimension not strong), color changeable effect are poor.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the embossed two-colour leather that a kind of third dimension is strong, double-colored, color changeable effect is good is provided.

For solving above technical problem, the utility model is taked following technical scheme:

A kind of embossed two-colour leather, wherein, this bicolor leather comprises base cloth layer, be coated in polyurethane foam layer on the described base cloth layer, be coated in the crazy-horse resin photochromic layer on the described polyurethane foam layer; Described bicolor leather upper surface is uneven, has formed a plurality of bizets and a plurality of ditch portion, and described bizet surface applied has one deck roller coating.

The surface layer resin of bicolor leather of the present utility model has adopted the crazy-horse resin photochromic layer, has increased the color changeable effect of bicolor leather greatly; Particularly also applied one deck roller coating, made bizet more outstanding on the one hand, moreover make color and/or glossiness difference between bizet and the ditch portion bigger, significantly improved the third dimension of the utility model bicolor leather, and two-color effect has been more obvious at bizet.In addition, when jack-up or stretching bicolor leather, bizet and ditch portion not only color distinction can be more obvious, and both color changeable effects also have very big difference, and be therefore double-colored and color changeable effect is all very strong.

The preferred moisture-curable resin bed of described roller coating makes bizet have bright penetrating crystal sense, and the synthetic leather third dimension is stronger.

The preferred elastic force cloth of described base cloth layer, so leather surface is by jack-up or when stretching, double-colored, color changeable effect can be better.

Generally speaking, compared with prior art, third dimension of the present utility model is stronger, and is double-colored, color changeable effect is stronger.

The specific embodiment

The utility model is described in more detail below in conjunction with accompanying drawing and concrete embodiment.

Embodiment 1

As shown in Figure 1, the utility model bicolor leather comprises base cloth layer 11, be coated in polyurethane foam layer 12 on the base cloth layer 11, be coated in the crazy-horse resin photochromic layer 13 on the polyurethane foam layer 12, after having applied crazy-horse resin photochromic layer 13, the synthetic leather that obtains is carried out embossing to be handled, make leather surface uneven, as shown in Figure 2, leather surface has formed a plurality of bizets 14 and a plurality of ditch portion 15, again bizet 14 surface applied is had one deck roller coating 141.

Roller coating 141 is selected the moisture-curable resin bed for use, makes bizet have bright penetrating crystal sense, and the synthetic leather third dimension is stronger; Perhaps also can select for use and the different resin bed of crazy-horse resin photochromic layer color, two-color effect is more obvious.

Base cloth layer 11 can adopt elastic force cloth, so leather surface is by jack-up or when stretching, and double-colored, color changeable effect can be better.

The bicolor leather of embodiment 1 gained has strong third dimension, preferable double-colored, color changeable effect.

As: color and glossiness difference between bizet and the ditch portion are very big, and darker, brighter penetrating, the quartzy sense of bizet color is strong; Ditch portion is of light color, mist sense, fold sense, be full of cracks sense are strong, and the bicolor leather third dimension is very strong.

Jack-up or stretching bicolor leather can be seen the color changeable effect of leather surface, and the color distinction of bizet and ditch portion is bigger, and the color changeable effect of bizet and ditch portion is obviously different, double-colored, color changeable effect is good.

The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
