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, and the synthetic leather in the prior art has a weak sense of genuine leather, which cannot meet people's requirements for high standards

Embodiment

[0016] Such as figure 1 Shown, a kind of synthetic leather with crazy horse contraction pattern, it comprises base fabric layer 1, the polyurethane foam layer 2 that is coated on described base fabric layer 1, the polyurethane adhesive that is coated on polyurethane foam layer 2 The knot layer 3, the crazy horse resin 4 coated on the polyurethane bonding layer 3, the modified polyurethane resin 5 coated on the crazy horse resin 4, and the acrylic modified resin layer 6 coated on the modified polyurethane resin 5 .

[0017] For the above-mentioned synthetic leather with crazy horse contraction patterns, the modified polyurethane resin 5 may preferably be silicone modified polyurethane, acrylic modified polyurethane, epoxy modified polyurethane or water-based modified polyurethane.

[0018] The above synthetic leather, in which the crazy horse resin coated on the polyurethane bonding layer, after the post-water kneading treatment, has fluff growing out, has a special velvet fee...

Abstract

The invention discloses synthetic leather with crazy horse contracted patterns, which comprises a substrate cloth layer (1), a polyurethane foaming layer (2) coated on the substrate close layer (1), a polyurethane adhesive layer (3) coated on the polyurethane foaming layer (2), crazy horse resin (4) coated on the polyurethane adhesive layer (3), modified polyurethane resin (5) coated on the crazy horse resin (4) and acrylic modified resin (6) coated on the modified polyurethane resin (5). In the synthetic leather, the crazy horse resin coated on the polyurethane adhesive layer can grow naps after performing posterior water massage treatment, has special nap feeling and is high in corium effect when adding with color-changing effect. In addition, the acrylic modified resin coated on the modified polyurethane resin can generate different patterns when combining and using contracted texture according to texture of release paper due to difference of polarities of the acrylic modified resin and the modified polyurethane resin, and then the synthetic leather has unique visual effect and strong visual aesthetics.

Description

technical field [0001] The invention relates to a PU synthetic leather, in particular to a synthetic leather with crazy horse fluff and contraction pattern and strong 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. In order to make synthetic leather meet people's needs for leather surface pattern...
