Textile Substrate Segmentation for Material Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile substrates containing mixtures of different materials face challenges in reprocessing due to material incompatibilities, leading to reduced quality and increased costs, making it difficult to recycle or dispose of them effectively.
Innovation Solution
A textile substrate design with distinct subsets of warp and weft threads made from different materials, where a destructible subset allows for easy separation of materials by chemical or physical methods, enabling separate processing and utilization of each material group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If textile substrates contain mixtures of different materials to achieve diverse functions and properties, then the functionality and performance of the textile substrate are improved, but the reprocessing and separation of materials become difficult and costly
Solution Approach 1:
The textile substrate is segmented into distinct material groups (first material group and second material group) that can be separated from each other. The substrate comprises warp threads and weft threads made of different materials arranged in a pattern that allows for selective separation, enabling each material group to be processed independently while maintaining the overall functionality during use.
2Loss of substance
If conventional reprocessing methods are used to recover materials from textile substrates, then material recovery is achieved, but the quality of recovered materials is reduced
Solution Approach 1:
By segmenting the textile substrate into separable material groups, each group can be recovered in its original form without contamination from other materials. This allows the first material group and second material group to be processed through appropriate methods independently, preserving the quality and properties of each material for reuse in new applications.
3Object-affected harmful factors
If textile substrates are designed to be biologically degradable for natural cycles, then environmental compatibility is improved, but other desired properties such as chafing resistance and durability are compromised
Solution Approach 1:
The textile substrate segments different material groups with different properties - one group can be designed for biological degradability to ensure environmental compatibility, while another group provides mechanical strength and durability. The segmentation allows these conflicting requirements to be satisfied in different parts of the same substrate.
Solution Approach 2:
The textile substrate uses composite construction with multiple material groups, where biodegradable materials are combined with durable materials in a controlled arrangement. This composite structure enables the substrate to meet both environmental requirements and performance requirements simultaneously.
4Loss of substance
If textile substrates use pure polymeric materials for technical cycle recycling, then material re-utilisability is improved, but functional properties such as moisture absorption and heat transport are insufficient
Solution Approach 1:
The textile substrate segments different material groups where one group provides technical cycle recyclability while another group delivers essential functional properties. The segmented structure allows each material group to fulfill its specific function without compromising the other.
Solution Approach 2:
The textile substrate employs composite materials combining polymers suitable for technical recycling with natural or functional fibers that provide moisture absorption, heat transport, and other desired properties. This composite approach enables both recyclability and functional performance.

AI summary
A textile substrate (1A) includes a warp and a weft and containing several different disposable and/or usable materials. A first subset of the totality of all warp threads and weft threads contains one or more warp threads (K1(1), K2(1), K3(1)) and one or more weft threads (S1(1)), wherein each warp thread of the first subset and each weft thread of the first subset is made of a first of the different disposable materials. A second subset of the totality of all warp threads (K1(2), K2(2), K3(2)) and weft threads contains one or more warp threads and/or one or more weft threads, wherein each warp thread of the second subset and each weft thread of the second subset is made of a second of the different disposable materials. A third subset of the totality of all warp threads and weft threads contains one or more warp threads and/or one or more weft threads (S1(3)), wherein each warp thread of the third subset and each weft thread of the third subset is made of a material (Z) that can be destroyed by means of a chemical and/or physical method. The warp threads and weft threads of the first and second subsets (K1 (I), K2(1), K3(1), K1(2), K2(2), K3(2)) are arranged in such a way that said warp threads and weft threads are not bound to one another and thus can be separated if the respective warp threads and/or weft threads (S1(3)) of the third subset are destroyed.
