Abstract
To provide with a method wherein a three-dimensional pattern having a clear convex ridgeline is patterned to a natural leather, and a natural leather seat with high design effect having the pattern. A patterned natural leather seat having on the surface one or several patterns having a convex ridgeline; a patterned natural leather seat wherein: the aforementioned pattern height is 0.5-2.0 mm, the aforementioned pattern base angle is 0.2°-89°, and the backside of the leather seat is flat.
Claims7
A patterned natural leather seat having on the surface one or several patterns having a convex ridgeline;
- a patterned natural leather seat wherein:
- the aforementioned pattern height is 0.5-2.0 mm,
- the aforementioned pattern base angle is 0.2°-89°, and
- the backside of the leather seat is flat.
A method of patterning on a natural leather comprising:
- the process of preparing a die having one or several concave parts, a die wherein the aforementioned concave part has a tilt angle of 0.2°-45° and a depth of 0.5-2 mm, and preparing a pressure receiver;
- the process of installing a natural leather wherein the thickness is 0.5-2.0 mm, in between the aforementioned pressure receiver and the aforementioned die;
- the process of pressing the aforementioned natural leather with the aforementioned die at a pressure of 0.1-5.0 MPa, and applying one or more selected from heat, ultrasonic waves and high frequency.
