Fabric with Moisture Management Function
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Athletic apparel fabrics struggle to effectively manage moisture, balancing comfort and performance by controlling sweat and heat dissipation without compromising appearance or comfort.
Innovation Solution
A knitted or woven fabric with a hydrophilic gradient is created using a semi-hydrophilic first layer and a hydrophilic second layer, where the first layer has a lower moisture regain (0.2%-6%) and the second layer has a higher moisture regain (4%-16%), allowing moisture to be pulled through the first layer and pushed out through the second layer, enhancing breathability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-layer fabric is used, then the structure is simple and manufacturing is easy, but moisture management performance is insufficient
Solution Approach 1:
The fabric is divided into multiple layers with different hydrophilic properties. The first layer (next to skin) has lower moisture regain (0.2%-6%) to wick moisture away, while the second layer (outer layer) has higher moisture regain (4%-16%) to absorb and evaporate moisture. This segmentation allows each layer to perform its specific moisture management function, resolving the contradiction between simple structure and effective moisture management.
Solution Approach 2:
Different regions of the fabric have different moisture regain properties tailored to their specific functions. The inner layer is designed with semi-hydrophilic characteristics for moisture wicking, while the outer layer is designed with hydrophilic characteristics for moisture absorption and evaporation. This local differentiation optimizes moisture management at each interface with the skin and environment.
2Ease of operation
If moisture is removed completely from the fabric, then comfort is improved by preventing wet cling, but breathability and cooling effect are reduced
Solution Approach 1:
The fabric controls moisture regain parameters within specific ranges rather than eliminating moisture completely. The first layer maintains moisture regain of 0.2%-6% to prevent wet cling, while the second layer maintains 4%-16% to provide breathability. This parameter optimization resolves the contradiction between comfort and heat dissipation.
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 fabric provides optimal comfort by preventing sweat accumulation next to the skin while allowing moisture to aid in cooling, ensuring efficient moisture management and quick drying.
Implementation Method 1
a first fabric layer having a first moisture regain and being a semi-hydrophilic or hydrophobic layer and a second fabric layer having a second moisture regain and being a hydrophilic layer, wherein the moisture from a wearer's skin is pushed through the first fabric layer and pulled out through the second fabric layer due to the presence of a hydrophilic gradient

AI summary
It is described a knitted/woven fabric with moisture management function comprising a first fabric layer having a first yarn and a second yarn knitted together to form a first layer being semi-hydrophilic or hydrophobic (comprising of lower moisture regain fibers), a second fabric layer comprising a third yarn and a fourth yarn knitted together to form the second fabric layer, the second fabric layer being fully hydrophilic (comprising of higher moisture regain fibers), wherein the first fabric layer has a moisture regain lower than the moisture regain of the second fabric layer providing a hydrophilic gradient between the first fabric layer and the second fabric layer of the knitted fabric pushing moisture through the first fabric layer in contact with the wearer's skin and out through the second fabric layer.
