Cooling Fabric Element Layout for Breathable Moisture Wicking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cooling fabrics that incorporate uniform layers of cooling materials often impede breathability and moisture transfer, failing to effectively manage body heat and moisture while maintaining the desired properties of the base fabric such as drape and stretch.
Innovation Solution
A pattern of cooling elements, including cooling gels or phase change materials, is integrated with a base fabric in a non-continuous array, allowing a designated percentage of the base fabric to remain uncovered, enhancing breathability and wicking by absorbing heat and undergoing conformational changes when exposed to moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a uniform layer of cooling material is incorporated into the fabric, then cooling performance is improved, but breathability and moisture transfer are impeded
Solution Approach 1:
The cooling material is divided into discrete particles or small elements rather than forming a continuous uniform layer. These segmented cooling particles are distributed throughout the fabric structure, allowing moisture and air to pass through the spaces between them while still providing cooling where the particles contact the skin.
Solution Approach 2:
The cooling material is applied non-uniformly with varying concentrations in different regions of the fabric. Areas requiring greater cooling have higher concentrations of cooling particles, while areas requiring better breathability have lower concentrations, optimizing both cooling performance and moisture transfer locally.
2Temperature
If a continuous layer of cooling material is used, then cooling effect is enhanced, but the desired characteristics of the base fabric such as drape and stretch are compromised
Solution Approach 1:
The continuous cooling layer is segmented into discrete particles that are individually distributed within the fabric. This segmentation allows the base fabric to maintain its natural drape and stretch properties while the cooling particles provide cooling where they contact the wearer's skin.
Solution Approach 2:
The fabric is constructed as a composite material system where cooling particles are integrated with the base fabric matrix. This composite structure combines the cooling functionality of the cooling material with the mechanical properties of the base fabric, achieving both cooling effect and desired drape/stretch characteristics.

AI summary
Embodiments of the present disclosure relate generally to cooling fabrics having an array of cooling elements coupled to a base fabric, and in particular to methods and fabrics that utilize an array of cooling elements coupled to a base material to absorb heat while also maintaining desired properties of the base material. In some embodiments, the cooling elements may include a cooling gel or polymer or a phase change material, and the cooling elements may undergo a chemical or physical change when exposed to moisture, thereby absorbing heat.
