Abstract

The invention provides leatherette paper with a double-color three-dimensional structure and a preparation method thereof. The paper surface of the leatherette paper is provided with a concave-convex three-dimensional structure. The concave-convex three-dimensional structure comprises concave parts and convex parts which are alternately arranged. The colors of the concave parts and the convex parts are different. Embossing is carried out in a female-male die matching mode through an embossing roller and a wool roller and is combined with surface intaglio coating, the leatherette paper with different colors of concave parts and convex parts and a concave-convex three-dimensional structure can be prepared, the operation is easy, and the paper has good expansion and contraction rate, folding resistance and flexibility and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of paper deep processing, in particular to a leather-filled paper with a two-color three-dimensional structure and a preparation method thereof. Background technique [0002] As a high-grade packaging paper, leather-filled paper has been accepted by people and is widely used in the packaging of various products, such as jewelry, cosmetics, high-end alcohol, stationery, leather goods, clothing and other products. Ordinary leather-filled paper is formed by the base paper after dipping dyeing, latex dipping, primer coating, top coating, embossing and other processes. The color of leather-filled paper is mainly achieved during the primer coating. Ordinary leather-filled paper can only be coated with a single color. After the primer color is coated, it is then top-coated and embossed to form a single-color, single-textured leather-filled paper. [0003] CN1063510558A discloses a production method of non-slip hig...
