Multi-ply Gauze Woven Fabric with Segmented Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-ply gauze woven fabrics fail to adequately enhance transparency preventing property, heat-retaining property, water absorbency, and softness while maintaining lightweight and breathability, especially when used in clothing and bedding.
Innovation Solution
A multi-ply gauze woven fabric is created by forming a tight plain-woven gauze layer A and a loosened plain-woven gauze layer B with connection parts, where the second beam feeds warps at a higher speed than the first beam, resulting in a fabric with improved properties.

Engineering Contradiction Analysis
1Object-affected harmful factors
If two or more sheets of gauze are combined to form a multi-ply woven fabric, then transparency preventing property is improved, but lightweight and breathability characteristics are compromised
Solution Approach 1:
The fabric is divided into multiple gauze layers (first gauze layer and second gauze layer) that are woven separately and then connected at specific positions. This segmentation allows each layer to maintain the lightweight and breathable characteristics of single-layer gauze while the combined structure provides improved transparency prevention.
Solution Approach 2:
The connection between layers is not uniform across the entire fabric but is localized to specific connection parts formed at predetermined positions. This local connection approach maintains the lightweight and breathable properties in non-connected areas while providing sufficient transparency prevention where layers are connected.
2Temperature
If two or more sheets of gauze are combined to form a multi-ply woven fabric, then heat-retaining property is improved, but breathability is reduced
Solution Approach 1:
The multi-layer structure with localized connections creates a segmented architecture that traps air pockets between layers, improving heat retention. Simultaneously, the unconnected regions maintain open spaces that allow air circulation, preserving breathability.
Solution Approach 2:
The invention transitions from a single-plane gauze structure to a multi-dimensional layered structure with vertical spacing between layers. This dimensional change creates insulating air pockets for heat retention while maintaining horizontal air flow paths for breathability.
3Object-affected harmful factors
If a towel woven gauze structure is used, then transparency preventing property, heat-retaining property, and water absorbency are improved, but softness is not improved and the fabric becomes heavy
Solution Approach 1:
The fabric is segmented into multiple gauze layers connected at specific positions rather than forming a continuous dense structure. This segmentation maintains the softness characteristic of gauze while the layered configuration improves transparency prevention and heat retention without requiring heavy pile structures.

AI summary
To provide a gauze woven fabric which has excellent opaqueness, moisture retention properties, water absorbency and comfort for skin (softness) while maintaining light weight and air permeability which are characteristic properties of gauze woven fabrics. Warps (1,2) are supplied from a first beam, and wefts (3,4) are then drawn across the warps to form a tight layer A. Warps (5,6) are supplied from a second beam that has a higher supply speed than that of the first beam, and wefts (7,8) are then drawn across the warps to form a loosened layer B. Subsequently, knotting points for connecting the layer A to the layer B regularly are formed.
