Hydroentangled Composite Fabric Strength Softness Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing woven fabrics for bedding applications face challenges in balancing strength, durability, softness, moisture management, and anti-allergen properties, while nonwoven fabrics lack the comfort and durability required for such uses.
Innovation Solution
A hydroentangled composite fabric is created by integrating a base woven fabric with a web of nonwoven fibers, using high-pressure water jets to entangle the fibers, resulting in a fabric with reduced pore size, enhanced durability, and improved moisture management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If woven fabrics are used for bedding applications, then strength and durability are improved, but softness and moisture management deteriorate
Solution Approach 1:
The patent combines woven fabric and nonwoven fabric into a composite structure where the woven layer provides strength and durability while the nonwoven layer contributes softness and moisture management properties, resolving the contradiction between strength and softness
Solution Approach 2:
The invention creates a composite fabric material consisting of two distinct fabric types (woven and nonwoven) bonded together, leveraging the complementary properties of each material to achieve both strength and softness simultaneously
2Duration of action of stationary object
If woven fabrics are used for bedding applications, then durability is improved, but moisture management deteriorates
Solution Approach 1:
The composite fabric merges woven fabric (high durability) with nonwoven fabric (superior moisture management) to achieve both durability and effective moisture management in a single material system
Solution Approach 2:
The invention applies different fabric types in different layers of the composite structure, with the nonwoven layer specifically positioned to handle moisture management functions while the woven layer provides structural durability
3Ease of operation
If nonwoven fabrics are used, then softness and absorbency are improved, but strength and durability deteriorate
Solution Approach 1:
The patent merges nonwoven fabric (soft and absorbent) with woven fabric (strong and durable) in a composite structure, allowing the nonwoven layer to provide softness while the woven layer reinforces strength
Solution Approach 2:
The invention creates a composite material system where the nonwoven fabric layer contributes softness and absorbency while being bonded to a woven fabric layer that provides the necessary strength and durability
4Quantity of substance
If nonwoven fabrics are used, then absorbency is improved, but durability deteriorates
Solution Approach 1:
The composite fabric combines nonwoven fabric (high absorbency) with woven fabric (high durability) so that the nonwoven layer absorbs moisture while the woven layer maintains structural integrity and durability
