Abstract
Provided are a biodegradable eco-friendly material and a manufacturing method thereof. The biodegradable eco-friendly material includes a biodegradable base fabric into which paper mulberry yarn and cotton yarn are mixed and woven, a leather layer made of a biodegradable material attached to one side of the base fabric, and a coating layer attached to the other side of the base fabric. Here, the base fabric may be woven in a state where 74 to 76 parts by weight of the cotton yarn and 24 to 26 parts by weight of the paper mulberry yarn are mixed.
Claims3
A method for manufacturing a biodegradable eco-friendly material including a biodegradable base fabric 10 into which paper mulberry yarn and cotton yarn are mixed and woven, a leather layer 20 made of a biodegradable material attached to one side of the base fabric 10, and a coating layer 30 attached to the other side of the base fabric 10, the method comprising:
- (a) a step of weaving the base fabric 10 including 74 to 76 parts by weight of the cotton yarn, and 24 to 26 parts by weight of the paper mulberry yarn;
- (b) a step of forming the coating layer 30 that is a transparent water-repellent coating layer on the base fabric 10 provided in the step (a);
- (c) a step of attaching the leather layer 20 made of the biodegradable material to the one side surface of the base fabric 10 provided in the step (a);
- (d) a step of aging the base fabric 10 to which the leather layer 20 is attached, provided in the step (c);
- (e) a step of performing embossing on a surface of the aged base fabric 10 provided in the step (d);
- (f) a step of performing an aqueous binder process onto the embossed surface provided in the step (e);
- and
- (g) a step of performing thermal compression bonding between the base fabric 10 and the leather layer 20 after the step (f),
- wherein the base fabric 10 and the leather layer 20 are attached to each other by a water-based adhesive,
- wherein the leather layer 20 is formed by a step of crushing cowhide and compressing and bonding the crushed cowhide to be attached to the other side of the base fabric 10, and
- wherein the coating layer 30 includes an animal protein component.
