Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dyeing base bodies face challenges in enhancing the quality and efficiency of vapor deposition transfer dyeing, particularly with nonuniform dyeing due to sublimable dye striking through in paper-based systems and reduced heating efficiency with glass or metal materials.
Innovation Solution
A dyeing base body comprising a metal sheet base with an electromagnetic wave absorption layer on the opposite side to the dye attachment, which has a higher absorption rate than the base, is used. This setup includes a dye holding layer and an electromagnetic wave absorption layer to ensure uniform heating and prevent dye strike-through, enhancing both quality and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If paper is used as the dyeing base body, then the sublimable dye can be attached, but the dye may strike through to the opposite surface resulting in nonuniform dyeing quality
Solution Approach 1:
The invention uses a composite structure consisting of a metal base body and a resin layer. The metal base body provides blocking capability to prevent dye strike-through, while the resin layer provides a surface for dye attachment. This composite material approach resolves the contradiction by combining materials with complementary properties.
2Productivity
If glass or metal material is used as the dyeing base body, then dye strike-through is prevented, but the efficiency of heating the sublimable dye is decreased
Solution Approach 1:
The resin layer acts as an intermediary between the metal base body and the sublimable dye. It provides a surface that facilitates efficient heat transfer to the dye while the metal base body prevents dye strike-through. This intermediary layer resolves the contradiction by enabling both effective heating and dye containment.
3Object-generated harmful factors
If a metal base is used, then dye strike-through is prevented, but the electromagnetic wave absorption rate is lower compared to paper
Solution Approach 1:
The invention changes the physical and chemical parameters of the base body by using a composite structure of metal base and resin layer. The resin layer has higher electromagnetic wave absorption rate than the metal base, and when combined in specific configurations, the overall structure achieves both dye containment and improved energy absorption characteristics.
