Claims20
Artificial leather having a microhardness of 45 to 59, wherein the microhardness is a maximum value measured immediately after a needle is in contact with the artificial leather at an indentation speed of 1 mm/s in a peak hold mode using a microhardness tester (Micro durometer, Model name:
- MD-1 capa, Brand:
- ASKER), i.e., when load holding time of the needle is 1 second.
A method of manufacturing artificial leather, comprising:
- step S1 of preparing a back layer formed of woven fabric or nonwoven fabric;
- step S3 of separately forming a pre-foam layer or foam layer and a skin layer by molding;
- step S5 of laminating the back layer on lower surface of the pre-foam layer or foam layer;
- step S7 of laminating the skin layer on an upper surface of the pre-foam layer or foam layer on which the back layer is formed;
- step S9 of coating an upper surface of the skin layer with a water-based surface treatment agent to form a surface treatment layer;
- step S11 of irradiating an upper surface of the surface treatment layer with infrared light;
- and
- step S13 of forming an embossed pattern through vacuum adsorption molding on upper surfaces of the skin layer and surface treatment layer heated by irradiation with infrared light,
- wherein the artificial leather has a microhardness of 45 to 59,
- wherein the microhardness is a maximum value measured immediately after a needle is in contact with the artificial leather at an indentation speed of 1 mm/s in a peak hold mode using a microhardness tester (Micro durometer, Model name:
- MD-1 capa, Brand:
- ASKER), i.e., when load holding time of the needle is 1 second.
