Recyclable Multilayer Textile for Scratch Protection in Heavy Item Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging textiles for heavy and fragile items are prone to damage due to rigid scrim layers and PVC coatings, which lack flexibility and recyclability, leading to scratches and environmental impact.
Innovation Solution
A multilayered textile comprising two superimposed scrim layers sandwiched between outer nonwoven layers, made from recyclable polyester fibers, providing strength, flexibility, and a soft surface without the need for PVC coating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a single heavy scrim layer is used for strength, then the textile can carry heavy items, but the textile becomes rigid and causes scratches
Solution Approach 1:
The single heavy scrim layer is divided into two thinner scrim layers (50-100 g/m² each). This segmentation reduces the rigidity and scratch-causing properties of individual layers while maintaining the total strength through the combined structure of multiple layers.
Solution Approach 2:
The textile combines multiple different materials: two scrim layers (50-100 g/m² each) bonded to outer nonwoven layers (200-250 g/m² total). This composite structure achieves both strength and flexibility, with the nonwoven outer layers providing a soft protective surface that prevents scratches.
2Ease of operation
If PVC coating is applied to reinforce scrim and increase flexibility, then the textile becomes more flexible, but the surface becomes hard and causes scratches
Solution Approach 1:
The harmful PVC coating is completely removed from the textile structure. Instead, the patent uses unplasticized polyester films and soft nonwoven outer layers to achieve flexibility without the scratch-causing properties of PVC.
Solution Approach 2:
The textile achieves flexibility through parameter changes in the scrim layer weight (reducing to 50-100 g/m² per layer) and the use of soft nonwoven outer layers with specific weight ranges (200-250 g/m²), eliminating the need for PVC coating while maintaining operational flexibility.
3Strength
If PVC coating is used to reinforce and protect the scrim, then the textile gains strength and flexibility, but the textile becomes non-recyclable
Solution Approach 1:
The harmful PVC coating is completely extracted from the textile structure. The patent uses only recyclable materials: polyester scrim layers and polyester-based nonwoven outer layers, making the entire textile recyclable while maintaining the required strength and flexibility.
Solution Approach 2:
The textile achieves the required mechanical properties through parameter optimization of natural recyclable materials: scrim layers of 50-100 g/m² bonded to soft nonwoven outer layers of 200-250 g/m², eliminating PVC while maintaining strength and flexibility through proper material selection and layer configuration.
