Sweatshirt Fabric: Properties, Care & Sewing Tips | Fabric Guide

Sweatshirt fabric is a knitted fabric where a backing thread is incorporated on the wrong side. Through this backing and subsequent brushing, sweatshirt fabric gets its typically soft and warm inner surface. The name combines 'sweat' and 'shirt' - the fabric was developed in the USA in the 1920s for sportswear.

Sewing Tips for Sweatshirt Fabric

Use the right needle: Use a jersey needle (ball point) in size 70-90. The rounded tip pushes the loops aside instead of piercing them, preventing holes in the fabric.

Choose elastic stitch: Set your sewing machine to an elastic stitch, such as zigzag or elastic straight stitch. These stitches allow the finished garment to stretch with the stretchy sweat fabric.

Pre-wash fabric before sewing: Wash the fabric before cutting to prevent shrinkage of the finished garment after first wash. Sweat fabric can shrink up to 5%.
