Embodiment 1

[0021] Such as figure 1 As shown, the two-color leather of the present invention comprises a base cloth layer 11, a polyurethane foam layer 12 coated on the base cloth layer 11, a crazy horse resin discoloration layer 13 coated on the polyurethane foam layer 12, and after the crazy horse is coated After resin discoloration layer 13, carry out embossing treatment to the obtained synthetic leather, make leather surface uneven, as figure 2 As shown, a plurality of crowns 14 and a plurality of grooves 15 are formed on the leather surface, and a layer of roller coating 141 is coated on the surface of the crowns 14 .

[0022] The roller coating 141 uses a moisture-cured resin layer to make the crown have a bright and transparent crystal feeling, and the synthetic leather has a stronger three-dimensional effect; or a resin layer with a different color from the color-changing layer of Crazy Horse resin can be used, and the two-color effect is more obvious.

[0023] The base cloth la...

Abstract

The invention discloses an embossing bicolor leather comprising a base cloth layer, a polyurethane foam layer coated on the base cloth layer and a crazy horse resin discoloration layer coated on the polyurethane foam layer. The upper surface of the bicolor leather is rough, and a plurality of crown parts and a plurality of groove parts are formed on the upper surface of the bicolor leather; and the surfaces of the crown parts are coated with a roller coating layer. Compared with the prior art, the bicolor leather is highly stereoscopic, and has double color and higher discoloration effect.

Description

technical field [0001] The invention relates to a PU synthetic leather, in particular to an embossed two-color leather with strong three-dimensional effect and good double-color and color-changing effects. Background technique [0002] PU synthetic leather usually includes a base cloth layer (also known as a cloth base material), a wet base adhesive layer (coated with polyurethane foam layer) coated on the base cloth layer, and a resin coated on the surface of the wet base adhesive layer. Surface layer. [0003] In the prior art, it is often necessary to carry out an embossing process on the synthetic leather coated with the resin surface layer, so that the surface of the synthetic leather, or the surface of the above-mentioned resin surface layer, becomes uneven, and the surface of the leather becomes uneven. From the perspective of the crown and the groove, there is a certain difference in the color and luster of the crown and the groove. Because the resin layer at the gr...
