Textile Fabric Structure for Waterproof Soft-Touch Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile fabrics coated with waterproof coatings suffer from poor softness, appearance, and flexibility, leading to peeling issues and inadequate waterproofing when meshes are large.
Innovation Solution
A textile fabric design featuring a main body with concave and convex surfaces, a film layer made of polyurethane or polyvinyl chloride, and a covering layer, which are integrated without adhesives, providing a waterproof and breathable structure with enhanced flexibility and tactile comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surfaces of textile fabric are coated with waterproof coating, then waterproof effect is improved, but softness and appearance deteriorate
Solution Approach 1:
The waterproof coating is segmented into discrete bead-like structures rather than forming a continuous film. These waterproof beads are distributed across the fabric surface, creating isolated waterproof zones that maintain fabric softness while providing waterproof protection through the collective effect of multiple bead structures.
Solution Approach 2:
The patent uses a knit fabric base structure that maintains flexibility and softness, combined with discrete waterproof bead coatings rather than rigid continuous films. This approach preserves the flexible nature of the original fabric while adding waterproof functionality.
2Reliability
If the surfaces of textile fabric are coated with waterproof coating, then waterproof effect is improved, but appearance deteriorates
Solution Approach 1:
The waterproof coating is applied locally as discrete beads rather than uniformly across the entire surface. This localized application allows different regions to have different properties - the beads provide waterproofing while the spaces between maintain the original fabric appearance, creating a heterogeneous structure that balances both requirements.
3Reliability
If the plurality of yarns are covered with waterproof coating, then waterproof effect is improved, but flexibility deteriorates
Solution Approach 1:
The waterproof coating is segmented into discrete beads on the yarn surfaces rather than forming continuous coatings. This segmentation allows the yarns to move and flex more freely while the bead structures maintain waterproof properties, resolving the contradiction between waterproofing and flexibility.
4Reliability
If the plurality of yarns are covered with waterproof coating, then waterproof effect is improved, but frictional resistance increases
Solution Approach 1:
The patent applies thin film waterproof beads rather than thick continuous coatings. These thin film structures provide waterproof protection while minimizing the increase in frictional resistance, allowing easier processing and handling of the coated yarns and fabric.

AI summary
A textile fabric is provided, including: a main body, a film layer and a covering layer. The main body includes two surfaces opposite to each other, and each of the two surfaces has a surface texture being concave and convex. The film layer is coveringly disposed on one of the two surfaces and is concave and convex corresponding to the surface texture, and the covering layer is coveringly disposed on the other of the two surfaces. Therefore, the film layer has an appearance corresponding to the surface texture, and the textile fabric has good toughness, is waterproof and is not easily damaged, and the covering layer provides comfortable feeling of touching.
