Solution Overview
Problem
Conventional materials used in handbags and wallets, such as PVC and leather, are not biodegradable and contribute to environmental pollution when discarded.
Innovation Solution
A biodegradable eco-friendly material is created by mixing and weaving paper mulberry yarn and cotton yarn, with a biodegradable leather layer and a water-repellent coating layer, using a water-based adhesive and animal protein components, to form a fabric that can decompose naturally within five years.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PVC or leather is used as material for handbags and wallets, then durability and water resistance are improved, but biodegradability deteriorates causing environmental pollution
Solution Approach 1:
The patent creates a composite material consisting of a base fabric layer (woven from synthetic fibers), a leather layer (providing durability and texture), and a coating layer (providing water resistance). This multi-layer composite structure combines the advantages of different materials while maintaining biodegradability through the use of biodegradable adhesives and treatments.
Solution Approach 2:
The patent modifies the chemical composition and physical properties of the material layers through specific treatments and coatings, changing parameters such as water resistance, durability, and biodegradation rate to achieve a balance between performance and environmental friendliness.
2Object-generated harmful factors
If biodegradable materials like paper mulberry yarn and cotton yarn are used, then environmental friendliness is improved, but water resistance and durability deteriorate
Solution Approach 1:
The patent applies a coating layer containing water-resistant agents to the biodegradable base fabric, creating a composite structure that provides water resistance while maintaining the biodegradable properties of the underlying fabric layers.
Solution Approach 2:
The patent applies different treatments to different layers of the material - the base fabric maintains its biodegradable natural fibers for environmental friendliness, while the coating layer provides localized water resistance and protection where needed.
3Reliability
If multiple layers and treatments are applied to achieve both durability and biodegradability, then material performance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the material into distinct functional layers (base fabric layer, leather layer, coating layer), each with specific properties and functions. This segmentation allows for optimized performance of each layer while maintaining overall biodegradability, and simplifies the manufacturing process by allowing independent production and assembly of layers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The material effectively prevents environmental pollution by decomposing naturally within five years, improving user satisfaction and durability while maintaining water resistance.
Implementation Method 1
The coating layer may include an animal protein component, and may be coated on the surface of the base fabric by spraying, so that the surface of the base fabric may be transparently water-repelled
Implementation Method 2
The base fabric and the leather layer may be attached to each other by an adhesive, and the adhesive may be a water-based adhesive
Implementation Method 3
it is possible to naturally decompose the base fabric within a period less than 5 years in a discarded state

AI summary
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.
