Adhesive Lathe Garment Patch Primer Buffer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Repairing rubber materials like latex garments is challenging due to messy and time-consuming adhesive application, uneven results, and the need for precise alignment, with solvent-based adhesives causing material curling and ripples, leading to imperfections and weakened repairs.
Innovation Solution
A garment repair patch with pre-applied acrylic-based adhesive and a natural latex sheeting carrier, utilizing an adhesion-promoting primer and a release liner, which simplifies the repair process by eliminating manual adhesive application and reducing waiting times, ensuring seamless integration and maintaining the garment's integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solvent-based rubber cement adhesive is applied to repair latex garments, then adhesion is achieved, but the solvent causes the latex to curl and ripple, resulting in visible imperfections and weakened repair
Solution Approach 1:
The patent introduces a primer layer as an intermediary between the adhesive and the latex garment. This primer layer prevents the solvent-based adhesive from directly interacting with and damaging the latex, thereby maintaining surface flatness while still achieving adhesion. The primer acts as a buffer that mediates between the adhesive's bonding function and the latex's structural integrity.
2Strength
If manual adhesive application is used for garment repair, then bonding is achieved, but the process is messy and time-consuming with long wait times for drying
Solution Approach 1:
The adhesive is pre-applied to the patch during manufacturing, allowing it to partially cure or set before application to the garment. This preliminary action reduces the waiting time required after application, as the bulk of the drying time has already occurred during controlled manufacturing conditions rather than during the repair process.
3Manufacturing precision
If precise alignment and careful securing of materials are required during repair, then repair quality is improved, but the process becomes more complex and difficult to perform
Solution Approach 1:
The patent combines multiple functions into a single integrated patch product: the adhesive, the carrier sheet, and the release liner are merged into one pre-assembled unit. This eliminates the need for separate steps of applying adhesive, aligning materials, and securing them, as all these functions are already combined and ready for direct application to the garment.
4Strength
If a multi-layer patch structure with primer and adhesive layers is used, then adhesion and durability are improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent optimizes the thickness and composition parameters of each layer to achieve the desired adhesion performance. By carefully controlling parameters such as adhesive layer thickness, primer concentration, and carrier sheet properties, the patent achieves strong adhesion without requiring excessive layer complexity, thereby balancing performance with manufacturability.
