Multilayer Textile Sleeve Interlocking Weft and Warp Yarns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing multilayer textile sleeves are inefficient due to the need for multiple operations to attach layers with different properties, leading to increased manufacturing costs and inefficiencies.
Innovation Solution
A multilayer textile material is created by interlocking weft yarns from one layer with warp yarns from another layer in a single weaving process, eliminating the need for secondary operations to attach the layers, and additional layers can be integrated in the same process to enhance properties such as insulation and abrasion resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual layers are constructed separately and then attached in secondary operations, then each layer can be optimized for specific properties (low friction, insulation, abrasion resistance), but manufacturing efficiency decreases and costs increase due to multiple operations
Solution Approach 1:
The patent combines multiple separate layer construction operations into a single integrated weaving process. Different yarn types (for low friction, insulation, abrasion resistance) are woven together in one operation to create multilayer textile material, eliminating the need for secondary attachment operations and improving manufacturing efficiency
2Reliability
If multiple separate operations are used to construct and attach layers, then layer attachment reliability can be ensured, but manufacturing time and costs increase
Solution Approach 1:
The construction and attachment of layers are merged into a single weaving operation where layers are created and interconnected simultaneously through the weaving process, eliminating separate attachment steps and reducing total manufacturing time while maintaining structural integrity
Solution Approach 2:
The interconnection between layers is built into the fabric structure during the initial weaving process rather than being added later. The weaving pattern itself creates the attachment mechanism, ensuring layer reliability is established from the outset rather than requiring subsequent attachment operations

AI summary
A multilayer textile sleeve and method of construction thereof is provided. The sleeve has an outer layer constructed at least in part from a first warp yarn extending along a length direction of the sleeve and a weft yarn extending transversely to the length direction. The sleeve further includes an inner layer constructed at least in part from a second warp yarn extending along the length direction and a weft yarn extending transversely to the length direction, with the second warp yarn being a different type of yarn than the first warp yarn. The outer layer and inner layer are connected to one another by interlinking the weft yarn of the outer layer with at least some of the second warp yarns of the inner layer and by interlinking the weft yarn of the inner layer with at least some of the first warp yarns of the outer layer.
