Reusable Adhesive Fabric Paper With Simplified Coating Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing fabrics for advertising, such as banners, suffer from low clarity and detail due to low printing quality, rapid decolorization, and require expensive and time-consuming thermal cutting, as well as being inconvenient to attach and remove.
Innovation Solution
A method for manufacturing adhesive fabric paper involving weaving polyester DTYs, shrinking the fabric, applying a coating solution with fixation-strengthening agents like titanium dioxide and polyvinyl alcohol, and laminating an adhesive-coated backing material, eliminating the need for a rear side coating layer while maintaining image quality and reusability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rear side of the fabric is coated multiple times with polyurethane resin and pigment mixtures, then printed images are protected from decolorization and yarns are prevented from becoming loose, but the manufacturing process becomes very expensive and time-consuming
Solution Approach 1:
The patent extracts and eliminates the complex rear side coating process while preserving its essential protective function through the adhesive-coated backing material that provides both adhesion and image protection in a single integrated layer
Solution Approach 2:
The patent combines the functions of rear side coating (image protection, yarn stabilization, UV blocking) and backing material attachment into a single integrated adhesive-coated backing material layer, eliminating the need for separate coating steps
2Object-affected harmful factors
If the rear side of the fabric is coated with polyurethane resin and pigment mixtures, then sunlight (UV light) is blocked and background colors are prevented from showing through, but the manufacturing cost and time increase significantly
Solution Approach 1:
The patent removes the separate rear side UV coating process and integrates UV protection functionality into the adhesive-coated backing material, achieving the same protective effect through a simplified single-step application
Solution Approach 2:
The adhesive-coated backing material serves multiple functions simultaneously: providing adhesive bonding, blocking UV light, preventing background color show-through, and stabilizing fabric yarns, replacing multiple separate coating layers with a single multi-functional material
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 adhesive fabric paper achieves high image resolution, prevents yarns from becoming loose, and can be easily attached and detached without residue, offering improved printing quality and cost-effectiveness compared to conventional methods.
Implementation Method 1
heating and rapidly cooling a woven fabric so that its width is shrunk
Implementation Method 2
preparing a coating solution to be applied to the front side of the fabric and aging it
Implementation Method 3
laminating an adhesive-coated backing material to the coated fabric

AI summary
Provided is an adhesive fabric paper that is used in color printers for personal computers, printing machines for indoor and outdoor advertisement, wide format printers, plotters, and so on to print colored images. In the invention, the rear side of the fabric is not subjected to gray coating and white coating, and the front side of the fabric is coated with a coating solution containing at least one fixation-strengthening agent selected from among titanium dioxide, silicon oil, silicon dioxide, polyoxyethylene sorbitan trioleate, and polyvinyl alcohol. The adhesive fabric paper shows the same functions as those of the rear side coating layer and can be manufactured by a simpler process at reduced costs.
