If you’re in the laundry, textile finishing, or upholstery space, you’ve likely stumbled across a common question that comes up again and again—especially when working with synthetic, versatile fabrics like acrylic: Can a steam press be used on acrylic? As someone who’s spent 12 years selling, testing, and troubleshooting steam presses for every type of textile from cotton canvas to silk charmeuse, I get how charged this question gets. On one side, you’ve got folks who swear by steam presses for smoothing even the most stubborn wrinkles. On the other, you’ve got the cautionary tales about synthetic fibers melting, warping, or turning yellow when exposed to too much heat or steam. The short answer is yes, you can use a steam press on acrylic—but there are a ton of factors that make the difference between a crisp, flawless finish and a ruined fabric. Let’s break this down like we would in a real workshop, no fancy jargon, just the hard lessons I’ve learned working with hundreds of clients over the years. Steam Press
First, let’s talk about what acrylic actually is, because that’s the foundation of everything here. Acrylic is a synthetic fiber made from polyacrylonitrile polymer, developed in the 1940s as a cheaper alternative to wool. It’s lightweight, resistant to mildew and fading, and keeps its shape way better than wool, which is why you see it in everything from sweaters and outdoor furniture upholstery to dance costumes and craft fabrics. But like all synthetics, acrylic has a low melting point—around 320°F (160°C) to 350°F (175°C), depending on the blend and manufacturing process. That’s the number every textile worker has memorized, because crossing that line is where the damage happens. Unlike cotton, which can handle hot steam and high heat without a second thought, acrylic will soften, stretch, or develop shiny, singed spots if you get too aggressive. That’s the core of the confusion: people think a steam press is just a bigger iron, so they crank up the heat and press away, not realizing steam presses deliver more consistent, concentrated heat (and steam pressure) than a handheld iron—so even a “low” iron setting might be too much for acrylic.
I’ve seen this mistake more times than I can count. A few years back, a client who ran a custom upholstery shop reached out panicking. She’d used a steam press to finish a set of acrylic outdoor chairs she’d just reupholstered, and when she lifted the press, there were large, shiny, translucent spots across the back of every cushion. She’d turned the press to what she thought was a “medium” setting, but for acrylic, that hit around 370°F—just 20 degrees over its melting threshold. The fabric was permanently damaged, and she had to re-upholster the whole set at her own cost. That’s the kind of error that makes people swear off steam presses for acrylic entirely, but it’s not the tool’s fault—it’s the user skipping the critical steps to adapt steam press settings to acrylic.
Now, let’s get into the specific, actionable steps that work for acrylic, based on years of testing in our workshop and feedback from thousands of our clients. The first and most important rule: always check the fabric’s care label first. That might sound basic, but you’d be shocked how many people skip this. Acrylic comes in many blends, too—acrylic-wool mixes, acrylic-polyester, even acrylic with a small percentage of spandex for stretch. Each blend has a different maximum heat setting. For example, pure virgin acrylic usually maxes out at 300°F (149°C), while acrylic-polyester blends can handle up to 320°F, and acrylic with spandex often only tolerates up to 275°F (135°C). If there’s no care label (common for vintage fabrics, craft fabrics, or remnants), do a small test patch first. Cut a 4×4 inch square of the same fabric, press it on a hidden, less visible area (like the inside of a chair cushion or the hem of a sweater), and check for melting, shrinking, or discoloration after 10 seconds. If it’s fine, you’re good to go; if not, dial the heat back.
Next, set your steam press correctly. Here’s where our clients ask the most questions, so let’s get specific: for pure acrylic, set the press to the “synthetic” or “low” heat setting—no higher than 300°F, and keep the steam pressure at a medium-low level. Too much pressure, even with low heat, can stretch acrylic fibers, especially if the fabric is still slightly damp (wait, damp? Wait a second—steam presses use steam, but do you need to pre-dampen acrylic? That’s another common myth. For most synthetics, pre-dampening isn’t necessary, and in fact, it can cause issues. If you over-saturate acrylic with steam, it can create water spots, or the moisture can draw out any dyes in the fabric, leading to bleeding. Instead, if you need a little extra moisture to get wrinkles out, use a light steam burst directly on the fabric just before pressing, not before you lay it on the press bed. That way, the steam is only where you need it, not all over the fabric.
Another game-changer: use a press cloth. I can’t emphasize this enough. A thin, 100% cotton press cloth (not a synthetic one) acts as a barrier between the hot press plate and the acrylic, preventing direct contact that can cause shiny spots or melting. I always recommend a medium-weight cotton handkerchief or a piece of old cotton bed sheet—something that’s not too thick that it blocks steam, but thick enough to protect the fabric. Never use a press cloth that has any synthetic threads, because those can melt and stick to the acrylic. If you’re working with a very delicate acrylic fabric, like a dance costume or a lightweight sweater, you can even use a second layer of tissue paper under the press cloth for extra protection.
Wait, what about the press time? That’s another big one. Unlike cotton, which you can press for 10 to 15 seconds to get deep wrinkles out, acrylic only needs 3 to 5 seconds per pass. Any longer, and the heat will build up too much, even at a low setting. If your wrinkles are still there after the first pass, don’t press harder or longer—lift the press, add a tiny bit of steam, and do a quick second pass. For very stubborn creases, like the seam on a pair of acrylic pants, you can gently stretch the fabric slightly while pressing, but be careful not to over-stretch, since acrylic can hold its shape, but too much tension will cause it to warp permanently.
Now, let’s address a common exception: what about acrylic faux fur? That’s another product our clients ask about all the time. Faux fur made from acrylic is super popular for coats, blankets, and trim, and people are always worried about pressing it without ruining the pile. The same rules apply, but with a few tweaks. For acrylic faux fur, never press directly on the pile—flip the faux fur inside out, lay it flat on the press bed (with a cotton press cloth over the back, not the pile), and use a very low heat setting (no higher than 275°F) and no steam. Steam will make the acrylic pile clump together and go flat, so stick to dry pressing only. If you need to smooth a crease in the backing, that’s fine, but the pile should always be faced away from the press plate.
I’ve had clients tell me they tried pressing acrylic with a handheld iron and it turned out fine, but the steam press was too hot. Why the difference? Handheld irons deliver heat in short bursts, and you’re constantly moving it, so you’re not holding it in one place long enough to build up too much heat. Steam presses, on the other hand, apply consistent, even heat across the entire surface at the same time, and if you set the temperature correctly, that consistency is a huge benefit—you won’t get streaky iron marks, and you can press large pieces like upholstery panels or bedspreads in minutes, not hours. The key is matching the press settings to the fabric, not just assuming all synthetics are the same.
Let’s talk about a time this went right, to put this all together. Last year, a client who made custom acrylic outdoor throw pillows reached out, saying she was struggling with wrinkled fabric that was driving her customers crazy. She’d been using a handheld iron, taking forever to get the wrinkles out, and still had uneven results. We walked her through our steps: check the care label (it said pure acrylic, max 300°F), set her steam press to 290°F, medium steam, use a cotton press cloth, and press for 4 seconds per pass. She called me a week later, thrilled—she was finishing 50 pillows a day, and the quality was way more consistent than with the iron, with zero damage. That’s the payoff when you use the right tool for the job, paired with the right settings.
Now, what are the risks if you don’t do this right? We already mentioned the shiny spots, melting, and stretching, but there’s another one that’s less talked about: yellowing. If you use too much heat over a long period, acrylic can start to break down, and it will develop a dull yellow tint, especially on light-colored fabrics. That’s permanent, so it’s better to err on the side of lower heat and more passes than higher heat and fewer passes. Also, never use steam pressing on acrylic that’s already been dyed with a water-based dye, or on fabric that has any other finishes, like flame retardant coatings common in outdoor acrylics. Those finishes can break down with high heat, leading to discoloration, so always test a small patch first, especially with specialty acrylic fabrics.
A lot of people will tell you steam presses are bad for acrylic, but that’s only true if you use them incorrectly. Steam presses are one of the most versatile tools for textile work, and with the right adjustments, they work beautifully on acrylic, saving you time, reducing labor costs, and giving you a much more consistent finish than handheld irons. We’ve tested our presses on every type of acrylic fabric, from lightweight craft fabrics to heavy-duty outdoor upholstery, and our customers’ results prove it works—when you follow the rules.
