Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional nonwoven textiles are unsuitable for apparel due to lack of stretch and recovery properties, heavy weights, poor drapability, rough hand, and inadequate insulation, leading to undesirable aesthetics and poor fit in garments.
Innovation Solution
A composite nonwoven textile with asymmetrical layers, featuring a first face for external exposure and a second face for skin contact, incorporating silicone-coated fibers and an elastomeric layer for stretch, recovery, and a pile for insulation, along with recyclable materials and selective color properties for aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional nonwoven textiles are used for apparel, then manufacturing simplicity is maintained, but stretch and recovery properties are insufficient
Solution Approach 1:
The patent applies composite materials by combining multiple fiber types (natural fibers, synthetic fibers, elastomeric fibers) in a nonwoven structure. This composite approach enables the textile to achieve stretch and recovery properties that single-material nonwovens cannot provide, while maintaining the manufacturing simplicity of nonwoven production methods.
Solution Approach 2:
The patent implements local quality by incorporating elastomeric fibers specifically in certain regions or at specific concentrations within the nonwoven structure. This allows stretch and recovery properties to be enhanced in critical areas without requiring the entire textile structure to be complex, thus resolving the contradiction between strength improvement and structural complexity.
2Weight of moving object
If traditional nonwoven textiles are used for apparel, then production efficiency is maintained, but weight is excessive
Solution Approach 1:
The patent applies parameter changes by modifying the fiber composition parameters and structural parameters of the nonwoven textile. By adjusting fiber diameter, fiber length, fiber type composition, and web density, the textile achieves reduced weight while maintaining production efficiency through standard nonwoven manufacturing processes.
3Shape
If traditional nonwoven textiles are used for apparel, then construction simplicity is maintained, but drapability is poor
Solution Approach 1:
The patent implements local quality by creating regions with different fiber compositions and structural properties within the nonwoven textile. Areas requiring better drape have optimized fiber arrangements and softer hand characteristics, while other areas maintain structural integrity. This localized optimization improves overall drapability without complicating the manufacturing process.
4Temperature
If traditional nonwoven textiles are used for apparel, then manufacturing simplicity is maintained, but insulation properties are insufficient
Solution Approach 1:
The patent applies composite materials by integrating multiple fiber types with different thermal properties into a single nonwoven structure. Natural fibers provide baseline insulation, while synthetic and elastomeric fibers contribute additional thermal retention capabilities. This composite approach achieves superior insulation properties without requiring complex multi-layer textile construction.
5Ease of operation
If traditional nonwoven textiles are used for apparel, then production simplicity is maintained, but hand feel is rough
Solution Approach 1:
The patent applies parameter changes by optimizing fiber diameter parameters, surface texture parameters, and web density parameters. Using finer denier fibers and adjusting the carding and bonding parameters during nonwoven production creates a softer hand feel while maintaining the simplicity of nonwoven manufacturing processes.

AI summary
This disclosure relates to a garment including a composite nonwoven textile associated with aesthetics, fit, functionality, and the like. The garment can include an upper-body garment (e.g., hoodie), with a fit that allows for relatively easy or free range of motion. In addition, the garment can include one or more various features that contribute to an aesthetic. For instance, the garment can include a seam construction that includes a relatively flat seam and that also provides an interesting aesthetic in which elements of the composite nonwoven construction are exposed. In some examples, a dual-layer hood assembly can include a seam construction that, for aesthetics and/or functionality, can allow a seam to be positioned on an inward facing surface of the hood. In some examples, the garment can include an elegant pocket construction that is associated with a clean aesthetic and reinforced pocket-opening edges and that is relatively easy to manufacture.
