Tips and Tricks for Decorating Rayon with Siser® Heat Transfer Vinyl

It’s no secret Siser® HTV can be applied on rayon! When combined with cotton and polyester the oh-so-popular triblend is created (which we’ve talked about before in this blog post.) When rayon is all mixed up with cotton and polyester like that the adverse reactions from heat application are less visible…most of the time. Polyester and rayon are both heat sensitive fabrics, so they can discolor from the high heat of the press. Not to worry though, you can still decorate those fabrics with Siser® HTV. Keep reading for tips on how!

Oftentimes rayon shirts will be blended with spandex. If the garment has 5% or more spandex we recommend using EasyWeed Stretch HTV for best results. And that’s exactly what I did with this coral J. America t-shirt that’s 95% rayon and 5% spandex. This blend of fabrics is a good choice for designs that will be printed across the chest since the shirt has plenty of stretch that the HTV can move with.

Be careful of that stretch though when you’re laying the shirt on the heat press platen. You don’t want to apply to a stretched out garment. It should lay naturally without any pulling. Additionally, ensure anything that could cause improper pressure is off the platen. In my case the bottom hem was easy to keep off the platen but the deep v-neck and sleeve seams were still on the edge, so I remedied the issue with a heat transfer pillow inside the shirt. The pillow elevates the pressing area above all the seams. Proper pressure is an important aspect in all HTV projects, but firm pressure is especially vital to applying EasyWeed® Stretch. Spending a little extra time adjusting the garment and your heat press will save you heartache from the washer later!

pre press rayon to remove wrinkles and moisture

When everything is situated, cover the shirt with a piece of parchment paper. You can use a heat transfer cover sheet, but it will hold the heat from the press a bit more, and we want to use the lowest heat possible for this delicate fabric. Press the shirt without any HTV for a few seconds at 280°F to smooth out wrinkles and draw out any moisture. A pre-press allows your HTV to stick it’s best.

Now you probably noticed I mentioned 280°F for your heat press and not the standard 305°F for EasyWeed Stretch. This significant drop in temperature is what’s going to prevent discoloring the fabric. Since the heat is lower the pressing time must be longer, otherwise the heat transfer vinyl will not stick. So after centering your first color (shiny side AKA carrier goes face up) place the parchment paper on top and press for 3 seconds. This will allow the HTV to bond to the fabric just enough to peel the carrier hot.

Place the second color (Sweet Mint for me!) and repeat the process above.

After peeling the second carrier the HTV may look and feel bonded to the shirt, but it needs a little more time to really sink in and call rayon “home.” 😉

Press each layer for only a few seconds

Recover the area with parchment paper for one last press. When pressing at 280°F we recommend adding 5-10 seconds to the suggested pressing time. Since these layers have only had 6 seconds collectively, I pressed for another 10 seconds to really bond the HTV to the rayon.

Take a look at what would have happened if I followed the same pressing steps, but with my heat press set to 305°F. The shirt on the left has an obvious box of lighter color caused by the high heat. The photo on the right shows the results of the pressing process we went over in this post.

I know which one I’d rather wear!

When applied properly, EasyWeed™ Stretch will last beyond 30 washes and can even outlast the garment!

This method of heat application is really handy to know for heat sensitive fabrics and the rules can be applied for other Siser® HTVs like Glitter, StripFlock®, and Holographic! Don’t lose these useful tips; pin the image below.

Rayon is stretchy, trendy, and unfortunately heat sensitive. No worries though, this method will save your tops from heat marks and not only works for rayon, but polyester and other heat sensitive fabrics!

    I have been asked to apply a design to a shirt that is ice silk. Do you know if this type of fabric withstand the heat? It did not come with any care instructions.

      Hi Tiffany! Although we have not experienced heat sensitivity with ice silk, it’s best to err on the side of caution especially if you only have 1 shot at it, so I’d recommend following these tips for applying on heat sensitive items.

    I have a shirt that is 96% Rayon and 4% Spandex that I need to put a design on at the top. However I don’t have the easyweed stretch just the regular easyweed and I won’t be able to get the stretched in time. I don’t want to ruin her shirt, will the regular htv work? P.S. it’s a maternity shirt and she probably won’t wear it after she delivers but i’m so nervous about the design looking wonky if it’s not stretched.

      Hi Twana, EasyWeed® will adhere to a rayon/spandex blend. However if your design covers an area where the fabric is stretched out, then the HTV may appear to pull/pucker instead of stretching nicely like EasyWeed® Stretch.

    Do you recommend flipping the Garment and pressing a second time on the inside? Wanting to have a secure bond without color fade or fabric melting.

    • Lily February 22, 2018 at 8:45 am - Reply

      Hi Laura! One press will be sufficient to bond the HTV as long as the time, temperature, and pressure are accurate. Adding a second press only increases the chances of overheating the fabric.

    I have a shirt that is 97% rayon and 3% spandex. I’ve tried the stretch vinyl and lowered the heat on my dry iron but I can get the vinyl to stick. What can I do?

    • Lily February 28, 2018 at 8:46 am - Reply

      Hi Brit! If you’re pressing at a lower temperature and increasing the length of your pressing time, but the HTV is still not sticking, it’s likely you need more pressure. This blog post explains how to achieve proper pressure. EasyWeed® Stretch likes firm pressure, so ensure you’re working on a hard flat surface. A clean wood cutting board is a good option.

    I have a tank top that I want to put vinyl on but it’s 65% polyester and 35% rayon. Is it possible to heat press it, is so what temperature and for how long? Thank You in advance for any help and tips.

    • Lily March 5, 2018 at 9:33 am - Reply

      Hi Tracey! A polyester/rayon blend is likely heat sensitive so I’d suggest pressing at 280°F for 15 seconds.

    Thank you very much for the detailed recommendations. A month ago I was ready to kiss each person who would show me this article. Recently at my job in coolessay my task was to make branded T-shirts for our employees. Of course, to buy a good T-shirt is a simple task, but it was difficult to find a suitable printing house that could correctly apply our logo. As you have already pointed out in this article, the incorrect use of temperature, or other mechanisms, can discolor or ruin a T-shirt. Some trial printers gave the wrong color on the T-shirt or there was not a clear image. For me it became a serious task to find professionals who could fulfill my order.

    Hi Robin! Sure, Glitter HTV could be applied to a rayon/spandex blend. You would still use the low temperature of 280°F like mentioned in this blog post, but you may need to press a few more seconds when using Glitter as opposed to EasyWeed® Stretch.

    Can Metal be applied as low as 280 as well? I’ve been getting discoloring on some tanks with rayon and was hoping to be able to lower the temperature on it too. Thanks!

    • Lily April 17, 2018 at 8:59 am - Reply

      Absolutely! You could even take it down to 270°F if the rayon is particularly sensitive, but remember to increase your pressing time by an additional 5-10 seconds.

    Will EasyWeed Stretch apply to 60% cotton/40% poly shirts? Or is ThermoFlex plus better?

    • Lily April 30, 2018 at 3:12 pm - Reply

      Hi Janera! EasyWeed® Stretch will definitely apply to a cotton/polyester blend shirt. Stretch is thinner than ThermoFlex Plus which allows for a softer hand and lighter weight design. It’s also a hot peel as opposed to a warm/cold peel which is beneficial for a quick production process. Just be sure to use use firm pressure when applying thin EasyWeed® Stretch 🙂

    Hi,
    will easyweed stretch show the texture of the fabric below it, like regular HTV?

    • Keith May 10, 2018 at 10:55 am - Reply

      EasyWeed Stretch has the same adhesive as EasyWeed with a thinner skin on top. If your application with EasyWeed shows the fabric texture, then an application of EasyWeed Stretch would yield the same look – but with more stretchability.
