Knitted Fabric Structure Balancing Absorbency, Drying, and Opacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional knitted fabrics face a trade-off between water absorbency and quick-drying properties, as well as between quick-drying and anti-see-through properties, making it difficult to achieve all three simultaneously.
Innovation Solution
A knitted fabric using low-torque crimped fibers with tailored density and thickness, specifically a composite yarn with false-twist crimped yarns in both S and Z directions, and entangled with interlacing processing, along with a hydrophilizing agent, to enhance water absorbency, quick-drying, and anti-see-through properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If natural fibers are used or weight per unit is increased to enhance water absorbency, then water absorbency increases, but quick-drying properties decrease
Solution Approach 1:
The patent applies parameter changes by precisely controlling the torque of crimped fibers (30 T/m or less), density (60-120 courses/2.54 cm, 45-80 wales/2.54 cm), and thickness (0.45 mm or less) to achieve optimal balance between water absorbency and quick-drying properties without using natural fibers or increasing weight
Solution Approach 2:
The patent uses composite crimped fibers combining different fiber types (polyester, polyamide, acrylic, or viscose) with specific torque characteristics to create a material that simultaneously provides high water absorbency through capillary action and rapid evaporation capability
2Loss of time
If water-repellent processing is applied to enhance quick-drying properties, then quick-drying properties improve, but water absorbency decreases
Solution Approach 1:
The patent changes the fundamental parameter from surface treatment (water-repellent processing) to fiber structure (low-torque crimped fibers with specific torque ≤30 T/m), enabling rapid drying through enhanced evaporation surface area while maintaining high water absorbency through capillary channels
3Loss of time
If weight per unit is reduced to enhance quick-drying properties, then quick-drying properties improve, but anti-see-through properties decrease
Solution Approach 1:
The patent resolves this contradiction by changing the thickness parameter to 0.45 mm or less while maintaining adequate density (60-120 courses/2.54 cm, 45-80 wales/2.54 cm), achieving rapid drying through reduced mass while preserving anti-see-through properties through optimized knit structure and fiber arrangement
Solution Approach 2:
The use of composite crimped fibers with specific torque characteristics enables the fabric to maintain sufficient opacity through fiber bundling and arrangement rather than relying solely on increased weight or thickness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a fabric with excellent water absorbency, quick-drying capabilities, and anti-see-through properties, as demonstrated by specific measurements and applications in various textile products.
Implementation Method 1
Because of the presence of such a crimped fiber in the knitted fabric, fine voids are created between single fibers, and also the knitted fabric surface becomes flat. As a result, the contact area with water increases, whereby the water absorbency improves.
Implementation Method 2
along with a hydrophilizing agent, to enhance water absorbency, quick-drying, and anti-see-through properties
Implementation Method 3
for sportswear and the like, not only water absorbency but also quick-drying properties, that is, the property of drying quickly after sweating, are required
