Methods for stabilizing and garments including stabilized quilted insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cold weather garments face issues with insulation stability, particularly with synthetic fibers that lose insulating properties when wet and have shorter lifespans due to compression, and down-filled garments that are prone to shifting and moisture retention.
Innovation Solution
The method involves arranging synthetic fibers into bundle structures and stabilizing them using a quilting stitch line system between fabric layers, creating channels that maintain the fibers' loft and insulation while allowing for longitudinal and lateral stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synthetic fibers are used for insulation, then insulating properties are retained when wet and drying time is reduced, but the fibers break down more quickly from repeated compression cycles
Solution Approach 1:
The synthetic fiber insulation is divided into discrete bundles that are individually stabilized within separate channels formed by quilting stitch lines. This segmentation prevents the fibers from breaking down during compression cycles by containing them in structured compartments, thereby extending garment lifespan while maintaining insulation properties when wet
Solution Approach 2:
The quilting stitch lines and bundle channels are pre-formed into the fabric layers before the synthetic fibers are inserted. This preliminary structural preparation provides immediate stabilization and protection for the fibers, preventing compression-induced breakdown from the outset and ensuring insulation retention throughout the garment's service life
2Ease of operation
If down fibers are used for insulation, then comfort and lightweight properties are improved, but the garment is prone to shifting and moisture retention
Solution Approach 1:
The insulation is organized into discrete bundles contained within channels defined by quilting stitch lines. This segmentation prevents the insulation material from shifting while maintaining even distribution across the garment, eliminating cold spots and puffy areas while preserving comfort
Solution Approach 2:
The bundle channel structure acts as an intermediary between the insulation material and the garment's movement. This intermediate structure stabilizes the insulation distribution while allowing the garment to move comfortably, preventing both shifting and moisture retention
3Quantity of substance
If synthetic batting materials are used for insulation, then cost is reduced, but comfort and insulation quality are compromised
Solution Approach 1:
The invention changes the structural parameters of synthetic fiber insulation by organizing it into bundles within channels, rather than using conventional loose batting. This parameter change transforms inexpensive synthetic fibers into a comfort-equivalent alternative to down, maintaining insulation quality and wearer comfort while reducing material costs

AI summary
Methods for stabilizing insulation and constructing garments from the insulation are disclosed. Methods include arranging the fibers into a plurality of bundle structures. The fibers may be synthetic fibers. The method may include receiving the bundle structures into bundle channels. The bundle channels are formed by tacks. The bundle channels enable the uniform distribution of the bundle structures prior to stitching quilting stitch lines. Multiple quilting stitch lines are stitched after the bundle structures are uniformly distributed. The quilting stitch lines are orthogonal to the longitudinal axis of the bundle structures. The quilting stitch lines provide lateral as well as longitudinal stabilization of the uniform density of the bundle structures. The distance between the quilting stitch lines may be based on the loft of the fibers and/or a required durability of the garment. The quilting stitch lines are generally horizontal, while the longitudinal axis of the bundle structures are vertical.
