Can you Put HTV on Polyester
Are you interested in printing heat transfer vinyl onto polyester? Absolutely! Mostly. The process is more complex than heat transfer vinyl printing on cotton. This post is essential if you need to create activewear with vinyl print for a client. It needs extra care, press time, and a lower temperature to print heat transfer vinyl on polyester.
Below you'll find instructions on how to print HTV on polyester. If you read it now and practice it a few times, you'll be able to print it on any activewear. You can use iron-on/heat transfer vinyl (HTV) for everything from T-shirts to cardstock. Heat-sealing vinyl to fabric requires both care and attention to both the vinyl and the fabric.
HTV On Polyester Temperature And Time Settings Depend On 2 key Factors
You have to take into account two main things when choosing time and temperature settings for your project:
1-You are pressing against a fabric
2-You should know which brand and type of HTV you are using.
In our analysis, the first significant finding is that fabric pressing guidelines may conflict with HTV pressing policies. To determine an equilibrium heat setting that allows the HTV to adhere well but doesn't damage the fabric, you may need to experiment.
Is Your Fabric Heat-Sensitive? Read The label Before Doing The Laundry.
If you have a fabric item, check the label for washing instructions. Using the ironing instructions will determine how you ought to apply the HTV. You may see a symbol or written instructions. The labels mentioned here are probably familiar to most of us (even if you ignore them like me). It would help if you pressed your HTV differently from a cotton shirt when using these fabrics.
Tips To Know Before Printing HTV On Polyester
Know Your Material.
You might have mistaken polyester for another material. Many tags provide incorrect information, which doesn't help. Alternatively, you might be using a cotton-poly blend rather than 100% polyester. It is always best to start at a cooler temperature if you are working with synthetics and natural materials. If you want higher heat instead, try a longer press time, which will take us to.
Increase The Duration Of Your Press.
When it comes to HTV, the adhesive activates at a lower temperature than in polyester fabric. You can prevent damage to your fabric by pressing the fabric longer rather than at a higher temperature. If it is not adhering correctly, pressing for a shorter time, checking, and then repressing shouldn't have any downsides. You should always make sure the washing machine's bond is strong before putting anything in it.
Test Your Fabric
When working with a large batch of shirts or fabric, make a small test run before committing to a more significant task. You can test if the iron adheres to the polyester by cutting off a small swatch and pressing it with your iron. After indulging in a washer session, you can then try to wash the garment. You could even test before selecting the vinyl by applying a heat press at different temperatures and seeing if it discolors. You'll know the limitations of each fabric and notice if something changes with a new batch very quickly!
Pick the Right Heat Transfer Vinyl
You can make a serious mistake when you use low-quality vinyl. Heat transfer types of vinyl that are easiest to use aren't necessarily the cheapest, but I wrote a guide to help you select the suitable vinyl for your project. Ideally, you want a HTV that has a strong adhesive, can be worn and washed without damaging it, and is available in various finishes. It isn't a good idea to switch brands for different looks, so choose one versatile enough to wear for any occasion. Using just one type of HTV, you don't have to worry about different settings for different brands, which saves me a lot of time!
Make Sure Your Fabric Is Heat-Sensitive
You may have a waterproof fabric or even a mix of polyester. Heat-sensitive HTV materials may be labeled "do not iron" for this material, so you need to choose one that releases its adhesive at a low temperature.
Avoid Thick Silicone Sheets.
It is excellent to use heat press pillows or silicone sheets to work with a material with many irregularities, such as buttons or zippers. However, they can make selecting the right temperature and pressure tricky, especially for flat materials. The sheet is the same one used to prevent vinyl from adhering to a heat press.
Setting The Correct Parameters
You might think this one is obvious, but before you start using vinyl, make sure that you read the instructions carefully. Using a different brand might be the problem if things aren't going as planned after following a heat press tutorial.
A Heat Press is Better than An Iron
To press polyester with HTV, it's advised not to use a household iron but rather a heat press machine. Why? You can only use light pressure when you use an ordinary household iron. You can close a high-pressure heat press machine, which can be very helpful when pressing HTV on polyester.
Therefore, purchasing a heat press machine is a good idea if you plan to print HTV on polyester fabrics.
In addition to being worth the investment, heat press machines can be set up to provide the exact time and temperature setting each time. It is not possible with a regular household iron.
Temperature And Timing Are Ideal
While working with HTV on polyester, observing the ideal temperature and time is essential. To accomplish that, test printing in fabrics is carried out on polyester shirts and cotton shirts. A temperature or time that isn't right for vinyl may cause it not to adhere.
The fabric can also scorch at high temperatures or for a prolonged period of time.
Additionally, excessive exposure time can lead to HTV not adhering correctly. Additionally, the vinyl may become dark if HTV is overheated.
Is Cotton Or Polyester Better For Printing?
Which fabric is best for printing HTV? Is it polyester or cotton? The pros and cons of both fabrics are equal. In choosing the type of fabric to use for your printing project, you should also consider the project you plan to do. You can then select polyester or cotton as appropriate.
Pros Of Polyester Shirts
- Moisturizes and absorbs sweat
- Make sure you choose a vinyl that matches your design.
- Ideally for sports shirts (activewear, gym clothes)
- Comparable to cotton shirts in terms of price
- Material that is lightweight
- Effortlessly wrinkle-resistant
- Resistant to shrinkage
- Suitable for sublimation printing
- These shirts are perfect for giveaways or one-off uses
Cons Of Polyester Shirts
- Printing HTV on it is more difficult
- A high temperature may cause it to scorch
- Captures and holds odors
Pros Of Cotton Shirts
- Non-clingy, soft, comfortable and breathable
- Easy to purchase or widely available
- It does not absorb odors
- Printing HTV on it is easier
- Due to heat transfer vinyl's design, it bonds well
- Heat presses don't scorch as much
- It can withstand high temperatures
Pros Of Cotton Shirts
- Stretches or sinks easily
- The fabric does not resist wrinkles
