Texturized Multifilament Woven Fabric for Stretchable Outdoor Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor fabrics lack breathability and stretch properties, making them unsuitable for applications requiring both weather resistance and form-fitting capabilities.
Innovation Solution
A non-coated, woven fabric made from multifilament yarns with texturized fibers, providing stretch in multiple directions, UV resistance, and a water-resistant finish without the use of laminates or coatings, allowing for breathability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fabric is made from woven construction with tight weave to achieve dimensional stability, then the fabric has good dimensional stability, but the fabric has little to no stretch in length or width direction
Solution Approach 1:
The patent changes the physical parameters of the yarn by using highly texturized multifilament yarns with specific tie-down counts (greater than 80 tie downs per meter) and denier ranges (50-800). This texturization creates inherent elasticity in the yarn structure itself, allowing the fabric to stretch while maintaining dimensional stability when woven.
Solution Approach 2:
The patent uses composite construction by combining highly texturized multifilament yarns with specific weave patterns to create a fabric that exhibits both dimensional stability and stretch properties. The composite nature of the texturized yarn structure provides both the stability and the elastic recovery characteristics needed.
2Reliability
If a fabric is coated with polymer film or laminated to improve water resistance, then the fabric has excellent waterproof properties, but the fabric loses breathability and traps water vapor
Solution Approach 1:
The patent employs a non-coated, non-laminated woven fabric construction that maintains an open porous structure. This porous weave allows water vapor to pass through the fabric, providing breathability while still achieving water resistance through the inherent properties of the texturized yarns and weave density, preventing water vapor trapping and mildew formation.
3Object-generated harmful factors
If a fabric is made non-coated to improve breathability, then the fabric has good breathability, but the fabric lacks sufficient water resistance and UV resistance
Solution Approach 1:
The patent achieves both breathability and weather resistance by changing the parameters of the yarn structure. Highly texturized multifilament yarns with specific tie-down counts and denier ranges provide inherent water and UV resistance without requiring coatings, while maintaining the porous structure needed for breathability.
