Description : Pro Spun® feels very much like Cotton, but is 100% Polyester. • 100% Polyester is heat sensitive and cannot exceed temperature thresholds higher than 320 degrees or shrinkage, bleeding or spot staining may occur. • Polyester requires a longer cooling time than Cotton. Avoid overlap of garments and decoration until garments are cooled. Failure to cool the fabric prior to stacking into a printer’s fold may cause the fabric and applied decoration to stick together. • Direct to garment (DTG) is primarily used on Cotton fabrics. Check with your supplier for information on requirements for DTG process on 100% Polyester.
