What Is Shirt Bleaching? 

Shirt bleaching is a t-shirt design process that alters the color of shirts by applying a common household cleaning agent- bleach. Yes, bleach is for cleaning and to help whiten clothes, and it can also design a shirt or highlight a design such as sublimation.

What Is Sublimation? 

What is sublimation paper? Sublimation is a process that turns sublimation ink into its gaseous state without becoming liquid. In the t-shirt printing industry, sublimation is a method of printing that transfers design into the fabric using ink and heat.

What really happens in sublimation is there is a transition of the ink directly from being solid to the gaseous phase without passing through the intermediate liquid phase.

Why Bleach Shirts For Sublimation? 

Bleached sublimation shirts have been around and trending for a while now. Bleaching shirts is all about design and emphasis. When you want a dark fabric with a highlighted design, bleach shirts before the sublimation process.

A bleached shirt will not only have an emphasized sublimation but will have more vibrant design colors as well.

How To Get A Sublimation Design?

There are lots of websites offering free design templates. Just search for them on the internet, and they will present themselves, just a click away. But still the best option is to get creative and make your own designs.

You can use Canva or Photshop or other design apps that can help you put your imagination into your sublimation shirts.

What Fabric Type Can We Use As Bleach Sublimation Shirts? 

The best shirts for sublimation are those that are made up of 100% polyester. Why polyester? The polymers of polyester open up when heated. When the ink dye is subjected to heat and changes into its gaseous form, it enters the fabric. Once it cools down, the dye has already bonded with the fabric.

The good thing about polyester is it does not wrinkle easily, and your design will be of high quality when sublimated onto it.

The downside is it’s not too comfortable to wear because polyester is not soft, and its smaller fibers contribute to its rough texture compared to cotton fabrics.

That’s why a poly-cotton blend is the best alternative and best fabric for hest transfer vinyl.

The best shirts for bleaching are made from cotton fabric. A Gildan brand women’s soft- style cotton shirts in Dark Heather or the Augusta Sportswear in Navy Heather are great for this. That is why a poly-cotton blend will be best for bleaching and sublimation.

Heat presses are hot enough to deliver consistent heat to your prints. This will ensure high-quality prints and a full-color design because it can accommodate your large designs as it has a large surface enough to accommodate any designs.

Poly Blend Shirt

As mentioned, you cannot just bleach any shirt, just as you cannot sublimate any fabric.

So, to meet these requirements for this shirt bleaching to sublimation project you need something that is best for both purposes.

How To Bleach A Shirt For Sublimation

White shirts with 100% polyester count are best for sublimation. So, if you’re not particular about the shirt color, you may start sublimating white shirts. But is 100% polyester best for bleaching too?

The answer is NO. The shirt that’s best for bleaching is 100% cotton. So, you cannot have both requirements met simultaneously.

How To Bleach A Shirt For Sublimation

Heather colors are the easiest to bleach, but you must also consider the polyester count, as sublimation is best with 100 % polyester. Heather colors refer to soft, muted colors from blending different colored fibers into one yarn.

With Heather, you usually see specks of white on a gray tee called Heather gray. Heather shirts usually have a higher polyester count with 65% polyester and 35% cotton, a great combination for sublimation. Although it is best to bleach a 50% polyester and 50% cotton shirt, it won’t look great after the sublimation.

Bleach

Chlorine bleach is used to whiten fabrics and remove stains, and it is the bleach mostly used to create unique designs and alter the color of fabrics. Bleach sublimation shirts are again making waves.

You cannot apply bleach directly onto the garment. Make sure you dilute it with water. The highly used and safe ratio is 1:1 water and bleach.

How To Bleach A Shirt For Sublimation

Some even use a design template that they put on the shirt so the spray will only reach the design area. Using light mist from the spray bottle, spray along the outer edge. This will give a splattered edge and ensures even application.

Spray Bottle 

The spray bottle will contain your mixture of bleach and water (1:1) that you’ll lightly spray to bleach shirts.

Hydrogen Peroxide 

You’ll use hydrogen peroxide to stop the bleaching process. So, guard the bleached area with your eyes to know when to interfere. This process will ensure that you capture the color intensity of the bleached shirts, which will affect your sublimation design transfer.

Other Supplies

Aside from the supplies mentioned above, you will also need the following to help your sublimation design succeed greatly.

  • Thermal Tape- to secure the paper while you print
  • Transfer gloves- wear gloves to protect your hands from bleaching shirts and from the ink and heat press
  • Butcher paper- this paper will be put inside the shirt during the bleaching and sublimation processes
  • Foam pillows- to help your shirts from direct heat during the heat press
  • Silicone cover sheets-to prevent ink from bleeding onto your heat press
  • Cardboard box- to protect your shirt so bleach won’t bleed through the back of the shirt
