Problems solved by technology

In the prior art, there are many technical difficulties in embossing synthetic leather. The visual effect of the pattern obtained by embossing is poor, and the embossing process requires a lot of equipment and high cost. At the same time, the retention time of the pattern obtained by printing is relatively short. , easy to fade, can not meet people's requirements for high standards

Abstract

The invention discloses synthetic leather with cracking patterns. The synthetic leather comprises a base cloth layer (1), a polyurethane foaming layer (2) coated on the base cloth layer (1), a polyurethane bonding layer (3) coated on the polyurethane foaming layer (2), a water-borne polyurethane resin layer (4) coated on the polyurethane bonding layer (3) and a polyurethane cracking resin layer (5) coated on the water-borne polyurethane resin layer (4). In the synthetic leather provided by the invention, the polyurethane cracking resin layer (5) coated on the water-borne polyurethane resin layer (4) has a special bright surface cracking effect, and the two layers are combined to realize a synergic promotion effect; and different patterns can be contracted according to different lines of release paper, and strong cracking contraction visual aesthetic feeling is obtained.

Description

[0001] technical field [0002] The invention relates to a PU synthetic leather, in particular to a synthetic leather with crack patterns. Background technique [0003] With the development of industrial technology, synthetic leather has been widely used in the production of luggage, clothing, footwear and other products. The base fabric of PU leather is a canvas PU material with good tensile strength. In addition to being coated on the top of the base fabric, the base fabric can also be included in the middle, so that the existence of the base fabric cannot be seen from the outside. PU leather has physical properties. Good, resistance to twists and turns, good softness, high tensile strength, and breathability, so PU leather is widely used in the fabric of footwear or the weight-bearing parts of bags. In order to make synthetic leather meet people's needs for leather surface patterns and patterns, it is often necessary to carry out an embossing process on the synthetic lea...
