Digital Printed Applique Emblems for Wash-Durable Garment Decoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for decorating and identifying garments, such as silk-screening, embroidery, and sonic welding, are complex, time-consuming, and often result in products that lack durability and aesthetic value, with existing transfer emblems being bulky, inflexible, and requiring multiple processing steps.
Innovation Solution
A process involving digital printing, etching, and cutting techniques to create a transfer appliqué with precisely registered elements that can simulate embroidered designs, using a design phase, separation phase, printing phase, coating/laminating phase, and etching/cutting phase, which eliminates the need for direct embroidery and results in a durable, aesthetically pleasing product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silk-screening is used to apply decoration and identification to garments, then the process is simple and direct, but the designs are flat, lack texture, and do not withstand repeated washings
Solution Approach 1:
The patent combines multiple functions into a single integrated emblem structure: the fabric substrate provides both the decorative design surface and the adhesive bonding layer, eliminating the need for separate embroidery and adhesive application steps. This merging achieves durable wash resistance while simplifying the overall process.
Solution Approach 2:
The emblem uses a composite structure consisting of a fabric substrate coated with adhesive material. This composite approach allows the fabric to provide texture and durability while the adhesive layer ensures strong bonding that withstands repeated washings, resolving the contradiction between simplicity and durability.
2Ease of operation
If embroidery is used to apply decoration and identification to garments, then the aesthetic value and texture are greatly improved, but the process becomes complex and time-consuming with separate stitching steps required for each color and design element
Solution Approach 1:
The patent uses a fabric substrate that is printed or dyed to create the decorative design, which is then coated with adhesive. This copying approach replicates the aesthetic appearance of embroidery without requiring actual stitching operations, dramatically reducing production time while maintaining visual appeal.
Solution Approach 2:
The invention extracts the essential aesthetic function of embroidery (visual design and texture) from its time-consuming stitching process. By using printed or dyed fabric with adhesive coating, the patent separates the decorative function from the labor-intensive application process, achieving high aesthetic value with improved productivity.
3Productivity
If transfer emblems are used to apply decoration to garments without embroidery, then the process is simplified, but the resulting product is inferior in durability to washing and cannot be ironed
Solution Approach 1:
The patent changes the material parameters of the transfer emblem by using a fabric substrate instead of paper or thin plastic. This fabric base provides the necessary durability and heat resistance for ironing, while the adhesive coating ensures wash fastness. The emblem can withstand repeated washings and ironing temperatures, resolving the durability issue while maintaining process efficiency.
4Ease of operation
If existing transfer emblems are used, then the application process is simplified, but the emblems are relatively large, bulky and inflexible
Solution Approach 1:
The patent uses a thin fabric substrate as the base for the transfer emblem, which inherently provides flexibility. The fabric can conform to the contours of the garment and stretch with the material, eliminating the bulkiness and rigidity problems of traditional transfer emblems while maintaining simple application procedures.
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 process efficiently produces multi-colored emblems that can be easily applied to garments, providing a realistic embroidered appearance without the complexity and cost of traditional methods, while ensuring durability and precise registration of design elements.
Implementation Method 1
adhesive application, such as thermal activated or pressure sensitive adhesives
Implementation Method 2
adhesive application, such as thermal activated or pressure sensitive adhesives
Implementation Method 3
The emblem can then be heat-sealed to a garment

AI summary
A process for applying digitally printed applique indicia which results in decorative and identification elements when applied to apparel and other textile products, the elements being an alternative to direct embroidery, embroidered emblems, thermo-transfer films, silk screen or sublimated printing. The production process includes a design phase (1 ), a separation phase (2), a printing phase (3), an optional traditional embroidery phase (4), and an etching/cutting phase (5) The process can incorporate embroidered elements but has the benefit of reducing or eliminating portions of stitching and or extra applique layers in the emblem The resulting product has superior care and durability characteristics to screen printing and heat transfers as the image is more wash fast and can be ironed The heat or pressure transfer capability can allow much faster customization of finished garments.
