Multi-Layer Gauze Fabric with Twisted Middle Yarn
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gauze fabrics are poor in bounce, softness, heat-retaining properties, and are difficult to sew due to their coarse-meshed structure, which affects their usability in various applications.
Innovation Solution
A gauze fabric structure comprising a surface layer and a back layer of non-twisted yarns with at least one middle layer of twisted yarns, where the layers are directly or indirectly joined, enhancing fabric strength and allowing for sewing while maintaining a soft touch and breathability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gauze is woven as a coarse-meshed plain woven fabric, then the fabric has a good touch feeling and breathability, but the fabric is poor in bounce, softness, heat-retaining property, and difficult to sew
Solution Approach 1:
The fabric is divided into multiple layers (surface layer, middle layer, back layer) with different yarn structures. The surface and back layers use non-twisted yarns for softness and breathability, while the middle layer uses twisted yarns for strength and elasticity, resolving the contradiction between comfort and structural integrity
Solution Approach 2:
The invention combines different types of yarns (twisted and non-twisted) in a composite multi-layer structure. This composite approach allows the fabric to simultaneously exhibit the softness and breathability of non-twisted yarns and the strength and bounce of twisted yarns
2Ease of operation
If gauze is woven as a coarse-meshed plain woven fabric, then the fabric has a good touch feeling, but the fabric is poor in heat-retaining property
Solution Approach 1:
The fabric structure is segmented into multiple layers with different yarn characteristics. The middle layer with twisted yarns provides heat retention while the surface and back layers with non-twisted yarns maintain soft touch feeling, thus resolving the contradiction between heat retention and comfort
3Ease of operation
If gauze is woven as a coarse-meshed plain woven fabric, then the fabric has a good touch feeling, but there is a difficulty in sewing
Solution Approach 1:
The fabric is segmented into layers with different functions. The middle layer with twisted yarns provides the strength needed for sewing and handling, while the surface and back layers with non-twisted yarns provide the desired soft touch feeling, resolving the contradiction between sewability and comfort
