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

Embodiment

[0016] As shown in Figure 1, a kind of synthetic leather with crystal feeling shrink pattern, it comprises base fabric layer 1, be coated on the polyurethane foam layer 2 on described base fabric layer 1, be coated on polyurethane foam layer 2 The polyurethane adhesive layer 3, the acrylic resin 4 coated on the polyurethane adhesive layer 3, the modified polyurethane resin 5 coated on the acrylic resin 4, and the crystal sense resin 6 coated on the modified polyurethane resin 5 .

[0017] Wherein the modified polyurethane can be silicone modified polyurethane, acrylic modified polyurethane, epoxy modified polyurethane or water-based modified polyurethane.

[0018] The above synthetic leather, the acrylic resin layer and the modified polyurethane resin layer coated on the polyurethane adhesive layer, because of the different polarity of the two, will produce a shrinkage pattern effect when used in combination. The shrinkage pattern can be determined according to the release pap...

Abstract

The invention discloses synthetic leather with crystal feeling contracted patterns, which comprises a substrate cloth layer, a polyurethane foaming layer (2) coated on the substrate close layer (1), a polyurethane adhesive layer (3) coated on the polyurethane foaming layer (2), acrylic resin (4) coated on the polyurethane adhesive layer (3), modified polyurethane resin (5) coated on the acrylic resin (4) and crystal feeling resin (6) coated on the modified polyurethane resin (5). In the synthetic leather, the acrylic resin layer and the modified polyurethane resin layer which are combined to use can generate unique contracted pattern effect, contracted texture of the acrylic resin layer and the modified polyurethane resin layer can generate different patterns according to different texture of release paper, the modified polyurethane resin layer is further coated with the crystal feeling resin layer, and then the synthetic leather has high-gloss and high-brightness effect, and has strong vision sense and crystal feeling.

Description

technical field [0001] The invention relates to a PU synthetic leather, in particular to a synthetic leather with a crystal-like contraction pattern and a unique visual effect. Background technique [0002] At present, synthetic leather products have gradually become a popular trend in the future, and 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. Synthetic leather is mainly composed of polyurethane resin layer and base cloth layer. ...
