Solution Overview

Problem

Current soil-resistant fabrics fail to completely remove oil stains after wiping or washing, leading to reduced effectiveness and altered fiber structures, necessitating a solution that maintains cleanliness and durability.

Innovation Solution

A fabric with an underlayer treated with an inorganic oxide and a Si-modified fluorocarbon-based hydrophobic compound forms a soil-resistant protection film, preventing oil corrosion and penetration, and ensuring no oil stains after wiping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fluorocarbon-based or silicon-based water repelling agent is used for surface soil resistance treatment, then the fabric gains soil resistance, but oil stains cannot be completely removed after wiping or washing

Engineering Contradiction:
Improvesoil resistanceVSAvoidoil stains
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The fabric surface treatment is divided into two separate layers: an underlayer applied first, followed by a soil-resistant protection film applied second. This segmentation allows each layer to perform its specific function - the underlayer provides a base for adhesion while the protection film provides oil resistance, resolving the contradiction between soil resistance and oil stain removal

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses a composite structure consisting of an underlayer and a soil-resistant protection film. This composite material approach combines the benefits of both layers to achieve superior performance in both soil resistance and oil stain prevention, eliminating the harmful effect of oil stains while maintaining reliability

Inventive Principle:
Principle #40Composite materials

2Object-generated harmful factors

If the fabric is washed several times after oil staining, then the oil stains may be removed, but the fiber structure changes and the effect is greatly reduced

Engineering Contradiction:
Improveoil stainsVSAvoidfiber structure
Core Design Contradiction:
Object-generated harmful factorsVSStability of the object's composition

Solution Approach 1:

The soil-resistant protection film is applied in advance to prevent oil stains from penetrating the fabric. By establishing this protective barrier before oil contact, the need for repeated washing is eliminated, thereby preventing fiber structure changes and maintaining stability

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The underlayer and protection film are applied beforehand to create a preventive system. This preliminary action ensures that oil stains cannot penetrate the fabric, eliminating the need for subsequent washing that would damage the fiber structure

Inventive Principle:
Principle #10Preliminary action
