Technical Field

[0001] The utility model relates to the technical field of synthetic leather, in particular to a yangbuck foamed synthetic leather. Background Art

[0002] As people's living standards improve, the demand for leather products gradually increases, and synthetic leather products gradually become a popular trend in the future. Synthetic leather is widely used in the production of luggage, clothing, shoes and other products.

[0003] Yangbuck foamed resin fiber can utilize its expansion and foaming characteristics to create a fluffy effect on the surface of synthetic leather. Some microspheres can rupture due to excessive expansion, which can form a velvety feel on the surface of the synthetic leather. Combined with appropriate post-production processes, leather products of different styles that are similar to the feel of real fur can be made. However, yangbuck foamed resin fiber is water and oil absorbent and easy to dye. Some existing yangbuck foamed synthetic leathers have poor water and oil resistance, which makes the synthetic leather easy to damage and the products made of synthetic leather are insufficiently durable. Therefore, a yangbuck foamed synthetic leather is proposed to address the above problems. Utility Model Content
