Soft polyurethane synthetic leather with skin-touch mercerizing 3D effect

Abstract

The invention provides soft polyurethane synthetic leather with a skin-touch mercerizing 3D effect, and relates to the field of polyurethane synthetic leather. The polyurethane synthetic leather comprises a polyurethane resin layer, a fiber layer is arranged on the surface of the polyurethane resin layer, a base layer for shaping the polyurethane resin layer is arranged above the fiber layer, and a bonding layer is bonded between the polyurethane resin layer and the base layer. According to the invention, the first cloth layer, the second cloth layer and the third cloth layer are bonded into a whole through the outer bonding layer and the inner bonding layer, so that the polyurethane resin layer is relatively stably shaped. Due to the arrangement of the fiber holes, the basic layer has sufficient deformation space in the bending deformation process, so that unrecoverable wrinkles generated on the surfaces of the base layer and the polyurethane resin layer due to overlarge deformation stress are avoided. In addition, due to the arrangement of the first cloth layer, the second cloth layer and the third cloth layer, when a plurality of main bodies are spliced, the first cloth layer, the second cloth layer and the third cloth layer at adjacent positions can be correspondingly sheared and inserted, so that the strength of connecting parts is high, the joint is not easy to slit, and the aesthetic degree is high.

Description

technical field [0001] The invention relates to the technical field of polyurethane synthetic leather, in particular to a soft polyurethane synthetic leather with a mercerized skin feel and 3D effect. Background technique [0002] Polyurethane synthetic leather belongs to the category of polyurethane elastomers. It has soft and natural luster, soft touch, and a strong leather-like appearance. It has excellent mechanical properties such as excellent adhesion to substrates, wear resistance, flex resistance, and aging resistance. At the same time, it also has the advantages of good cold resistance, breathability, washability, convenient processing, and low price. It is the most ideal substitute for natural leather. [0003] In order to improve the use effect of synthetic leather, 3D effect soft polyurethane synthetic leather is widely used, but this kind of synthetic leather is basically made of base cloth coated with polyurethane material, which has poor anti-wrinkle effect,...
