How to Bleach sweatshirts for Sublimation

Sublimation is a creative and widely-used printing method that involves the transfer of ink onto fabric or other materials. The process uses a heat press, and heat-sensitive inks that are transferred to the material, ensuring that the design lasts longer and is more durable than a typical screen print. When it comes to sublimation printing on sweatshirts, however, many factors come into play. One of the most important factors is bleaching. This article will teach you how to bleach sweatshirts for sublimation, so you can get the most out of this popular printing method.

Understand the Importance of Bleaching Sweatshirts for Sublimation

Bleaching sweatshirts is an essential step that you need to take before you sublimate onto them. Bleaching removes any natural colors that might affect the vibrancy and pigment of the ink when it is transferred. With sublimation printing, the ink needs to be as vibrant and accurate as possible to ensure that the final product turns out perfectly. Therefore, bleaching is crucial for sublimation printing. Without proper bleaching, the final product may appear dull, and the colors may not be as vibrant as you expect.

Materials Needed for the Bleaching Process

Before you start bleaching, ensure you have all the necessary materials. Ice-cold water, chlorine bleach, protective gloves, basin, and measuring cups are essential materials you will need. Additionally, a well-ventilated area and protective goggles will come in handy. Ensure you have your sweatshirt within reach because as soon as you mix the water and bleach, you will need to act quickly. Once you have all the requisite materials, you can start the bleaching process.

Step-by-Step Guide to Bleaching Sweatshirts for Sublimation

Step one: Fill your basin with ice-cold water.

Step two: Add a quarter cup of bleach to the ice-cold water.

Step three: Mix the water and bleach thoroughly.

Step four: With protective gloves on, submerge the sweatshirt into the water and ensure that it is entirely covered.

Step five: Wait five minutes or until the sweatshirt's color changes.

Step six: Take the sweatshirt out and rinse it in cold water to stop the bleaching process.

Safety Tips for Bleaching Sweatshirts for Sublimation

Bleaching is a complicated process that can be dangerous if not done correctly. Here are a few safety tips that you must observe:

1. You should never bleach a sweatshirt that's not 100% cotton. Polyester or poly blend materials will not bleach, and you may ruin the sweatshirt by using too much bleach.

2. Always use protective gloves and goggles when handling bleach.

3. Avoid inhaling the fumes, work in a well-ventilated area.

4. Follow the mix ratio, do not use too much bleach, as it can damage the fabric's fibers.

5. Keep bleach and bleached garments away from children and pets.

Post-Bleaching Care for Your Sweatshirts

After the sweatshirt has been bleached, you need to treat it with care from washing to storage. Always wash the sweatshirt on a gentle cycle with mild detergent, and hang it to dry. Avoid using a dryer because high heat can damage the fabric fibers, making the sweatshirt unusable. Once the sweatshirt is dry, store it in a cool, dry place until you are ready to sublimate on it.

Conclusion

Sublimation printing is an exciting, vibrant, and durable method of printing images and designs onto sweatshirts, and many other materials. To achieve impeccable results, you need to ensure that you have bleached your sweatshirt before the sublimation process. By following our guidelines on how to bleach sweatshirts for sublimation, you will be able to achieve accurate and vibrant results every time.
