Rigid Collar Stand Using Fused Substrate for Dimensional Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Men's dress shirts experience shrinkage and stretching issues due to fabric properties, leading to a loss of fit and comfort over time and multiple washes, as traditional collar stands lack rigidity and stability.
Innovation Solution
A collar stand is designed with an inner and outer piece fused with a rigid fusible substrate, providing minimal stretch and shrinkage, typically between 0% to 1.5% in one direction, to maintain shape and form, and is attached to the garment body with specific sewing dimensions to ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fabric collar stands are used, then the garment is comfortable and flexible, but the collar stand shrinks and stretches over time and washes
Solution Approach 1:
The collar stand is constructed by fusing a fabric layer with a rigid fusible substrate layer. This composite structure combines the flexibility and comfort of fabric with the dimensional stability and rigidity of the substrate, preventing shrinkage and stretch while maintaining wearability.
Solution Approach 2:
The invention changes the physical and chemical parameters of the collar stand material by using a rigid fusible substrate with specific properties (minimal stretch 0-5%, minimal shrinkage 0-5%). This transforms the material from traditional flexible fabric to a stable composite that resists dimensional changes.
2Reliability
If a rigid collar stand is created using fusible substrate, then shrinkage and stretch are minimized, but the manufacturing process becomes more complex
Solution Approach 1:
The solution uses a two-layer composite construction (fabric + rigid fusible substrate) that achieves dimensional stability through material properties rather than complex structural designs. The simplicity of the layered approach minimizes manufacturing complexity while maximizing reliability.
3Ease of operation
If fabric with higher stretch is used for the collar stand, then comfort and flexibility improve, but the collar stand loses its shape and fit over time
Solution Approach 1:
The composite structure allows the fabric layer to provide flexibility and comfort while the rigid fusible substrate layer maintains the collar stand's shape and form. This division of functional roles enables both comfort and shape retention simultaneously.

AI summary
A garment includes a collar stand attached to a garment body. The collar stand is formed from an inner piece and an outer piece, and wherein at least one of the inner piece and the outer piece comprises a fabric fused with a rigid fusible substrate. The fabric fused with a rigid fusible substrate has between 0% to 5% stretch, preferably between 0% and 3% stretch, and more preferably between 0% and 2% stretch in at least one direction thereof, and the fabric fused with a rigid fusible substrate has between 0% to 5% shrinkage, preferably between 0% and 3% shrinkage, and more preferably between 0% and 2% shrinkage in said at least one direction thereof.
