Magic Trick For Sublimating A Cotton Fabric :

To figure out how to sublimate cotton fabric, I did a great deal of research and settled on Sublimation Coating Spray. In my experiments, I discovered how easy it is to sublimate cotton using coating spray.

A sublimation coating spray can be used on any fabric, but specifically on 100% cotton. During my experiments, it worked like a charm. Using this spray was a breeze. Because it dried so fast, I did not have to wait very long for it to dry. All ingredients are in one compound, so I did not have to mix anything beforehand. I just directly sprayed it onto the fabric. The fabric is protected by this coating, preventing abrasion, scratching, rubbing, and ink smudging. It provides such a beautiful glossy sheen, and the colors emerged so vibrantly as well.

How to sublimate on cotton: Step by Step Process

Step 1: The first thing you need to do is press the cotton or fabric you want to sublimate for a few seconds using a heat press. Make sure it is wrinkle-free before you begin.

Step 2: Prepare your design and print it with a sublimation printer on sublimation paper. Afterward, cut it out.

Step 3: Then simply apply the spray to the fabric and let it dry. It can either be allowed to dry naturally or pressed again using a household iron or heat press machine. Make sure that no more moisture remains on the fabric.

Step 4: Use heat-resistant tape to set the design on the fabric and press it again (from medium to high pressure) until it transfers completely to the fabric.

Step 5: Finally, gently remove the tape and paper. Your design is now ready to wear.

There may be a slight scratchy feeling on the surface, but it will disappear after one wash.

Precautions:

  • You should only use sublimation ink. Avoid using pigmented or dyed ink
  • Sublimation ink works best on sublimation papers. Avoid using regular paper for printing.
  • Depending on your equipment, set the temperature appropriately.
  • Dark-colored fabric is not recommended.
