How to Heat-Set Fastex - High Definition Textile Ink

Heat-Setting FAS Fastex Fabric Ink.

What makes Fastex so durable is the heat setting.

All fabrics that can been ironed at a good hot setting suitable to the fabric can be painted on.  

​The heat setting fuses the ink and the fabric fibres together to make a lasting durable finish. ​

Fastex HD Textile Inks need to be heat set if they're painted on something that's going to be washed.
  • Allow the garment to dry thoroughly before attempting to heat set.   
  • Always iron with a dry press setting. Do not steam iron. Your iron should be set at the highest setting allowed for the decorated fabric.
  • Protect the ironing board with a paper towel or some waste fabric as during curing some pigment staining may occur. For t-shirts, place a paper towel or waste fabric inside the shirt.
  • Heat set with a household iron at medium setting for 3 to 5 minutes on each side.  The process is the similar as ironing a garment, except you'll iron an area for longer than you would to iron out creases.  It is all about heating the fabric to fuse the ink inside the fibre.
  • Iron slowly but be sure to keep the iron moving at all time so there is not damage to the fabric design.
