What is Spacer Fabric?
Spacer is a highly breathable, cushioned, multi-faceted fabric, used in the practical making of a wide variety of products.
How is it made?
Understanding the creation and production process of Spacer fabric is paramount to understanding what Spacer fabric actually is. Unlike regular, 2D fabrics, Spacer uses two separate fabrics, joined by microfilament yarn, to create a breathable, 3D "microclimate" between layers. Heat and vapor leave the body, moving to this highly permeable layer. Then, the cool air provided by this naturally ventilating pushes out the heat and vapor, providing temperature control and maximum air circulation.
Using ASTM D737, the standard test method for air permeability of textile fabrics, air was drawn through both knit fabrics and Spacer fabrics. While the knit fabrics received only a 10.7 cfm (cubic feet per minute), Spacer Fabrics received a 99.1 cfm, meaning it was almost 10 times more permeable than regular knit fabrics.
Where is it used?
Spacer fabric is everywhere! Found in tennis shoes, backpacks, car seat cushions, bras, this fabric's naturally ventilating properties make it perfect for everyday use. Additionally, Spacer's soft and cushiony nature reduces force, making it ideal for surfaces of pro-longed rest. Because it is lighter and breathes better than traditional mattresses, many European countries have replaced spring and foam with Spacer fabric.
