Double-Layer Adhesive Tape for Non-Quilted Garment Bonding Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-quilted garment technologies face issues with adhesive bonding strength, seam leakage, and thermal insulation due to the use of double-sided melt tapes, which result in poor bonding and filling retention, leading to warm air escape and water ingress.
Innovation Solution
A tape made from a cut piece of double-layer woven fabric with adhesive portions on both sides, allowing for bonding of face and lining fabrics without direct joining, enhancing peel resistance and thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive bonding is used to bond fabrics together, then stitching operations are eliminated and seam-related problems are solved, but the bonding strength is insufficient and fabrics easily peel off
Solution Approach 1:
The invention uses a composite bonding structure combining adhesive material with raised fibrils on fabric surfaces. The adhesive provides initial bonding while the raised fibrils create mechanical interlocking, forming a composite bonding system that achieves both ease of manufacture and high bonding strength.
Solution Approach 2:
The invention changes the surface morphology parameter of the fabric by raising fibrils to create an uneven surface. This parameter change enables mechanical interlocking with the adhesive, significantly improving bonding strength while maintaining the simplicity of adhesive bonding application.
2Strength
If tiny fibrils are raised on textile surface to induce anchoring effect, then bonding strength is improved, but productivity decreases due to required abrasion and scratching steps
Solution Approach 1:
The raised fibrils are pre-formed on the fabric surface before adhesive application. This preliminary action eliminates the need for time-consuming abrasion and scratching steps during the bonding process, maintaining high productivity while achieving strong mechanical interlocking.
Solution Approach 2:
The fabric structure itself provides the bonding enhancement through pre-raised fibrils, eliminating the need for external abrasion or scratching equipment. The fabric serves its own preparation function, streamlining the manufacturing process.
3Shape
If double-sided melt tape is used to bond face fabric and lining fabric, then non-quilted structure is achieved, but bonding strength is poor and peeling occurs under simultaneous pulling forces
Solution Approach 1:
The bonding system combines adhesive material with fabrics having raised fibrils, creating a composite structure that maintains the non-quilted shape while providing superior peel resistance through mechanical interlocking at the adhesive-fabric interfaces.
4Shape
If conventional bonded structure with double-sided melt tape is used, then non-quilted article is produced, but filling amount is limited and thermal insulation properties are poor
Solution Approach 1:
The enhanced bonding strength from the composite adhesive-fibril structure allows for greater filling volume without compromising bond integrity, thereby improving thermal insulation properties while maintaining the non-quilted structure.
