Discover the complexities of cotton spandex fabrics and learn how to choose the right material for your project. Here are some key properties to keep in mind:

Stretch Percentage

Cotton spandex fabrics can stretch anywhere from 12-50%, depending on manufacturing processes and cover factor. Communicating your stretch requirements to your manufacturer can help deliver you the right stretch.

Spandex content: More spandex content does not mean more stretch. Focusing on the stretch percentage rather than spandex content is important. For example, having a few well-functioning rubber bands is better than many stretched-out ones.

Growth

This refers to the fabric’s ability to stretch and not be pulled back by spandex after stretching. Conducting growth tests in a lab using the proper protocol & equipment is essential.

Shrinkage

To produce the right quality garment, cotton elastane fabrics must have controlled shrinkage.

Specialized Spandex Yarns

Consider using specialized elastomeric yarns, such as dual-core, to reduce growth and provide a more consistent stretch effect.

We hope these insights help you make informed decisions when it comes to cotton spandex fabrics.
