Whether you're making activewear, slim-fit polos, or just want more comfort in your everyday tee — stretch fabrics play a crucial role in how your garments perform and feel.
Among the most common stretch fibers are Spandex and Lycra. Let’s break down what they are, how they work, and when to use them.
🧪 What is Spandex?
Spandex (also known as elastane) is a synthetic fiber known for its high elasticity. It can stretch up to 500% of its length and return to its original shape.
-
Lightweight and breathable
-
Blends well with cotton, polyester, nylon
-
Adds flexibility without adding bulk
-
Used in athleisure, sportswear, fitted T-shirts
🤔 What about Lycra?
Lycra is a brand name for premium spandex, originally developed by DuPont. So while all Lycra is spandex, not all spandex is Lycra.
-
Lycra tends to have more consistent stretch, better durability
-
Preferred for high-performance or branded apparel
-
Slightly higher cost, but better long-term feel
🧵 When to Use Stretch Fabrics?
-
Activewear / gym clothing: Polyester + Spandex blends (85/15 or 90/10)
-
Fitted T-shirts or polos: Cotton Spandex or CVC Spandex
-
Performance uniforms: For flexibility, shape retention, and comfort
-
Undergarments or layering base tees
At HEM APPAREL, we often recommend stretch blends for any style that requires shape retention, body-hugging fit, or movement comfort — without compromising structure.
