Thread Types for Embroidery: Why Quality Thread Means Lasting Design
You spent weeks choosing the perfect design for your custom towels. The logo looks sharp. The names are spelled right. Everything arrives looking flawless.
Then, after a dozen washes, the embroidery starts fraying. Colors fade. Threads pull loose. What happened?
In most cases, the answer is thread quality. It's the part of embroidery that rarely gets discussed, but it determines whether your custom design lasts twelve washes or twelve years. Here's what you need to know.
The Three Main Thread Types for Embroidery
Not all embroidery thread is created equal. The three types you'll encounter most often are rayon, polyester, and cotton. Each has strengths and trade-offs, and the right choice depends on what you're embroidering and how it will be used.
Rayon: Beautiful but Fragile
Rayon thread is the showpiece of the embroidery world. It has a natural, silky sheen that catches light beautifully. Colors appear rich and vibrant straight off the machine.
It's also the most affordable option, which makes it popular for decorative items and one-time display pieces. If you're embroidering a wall hanging or a piece that won't see much wear, rayon delivers stunning results at a reasonable price.
The downside? Rayon doesn't hold up to heavy use. It's weaker than polyester, more prone to breakage during stitching, and loses its luster after repeated washing. Chlorine, bleach, and extended sun exposure accelerate the decline. For items that will be washed frequently — like towels — rayon is a poor match.
Polyester: The Workhorse
Polyester thread is the industry standard for embroidery on textiles that need to perform. There's a reason it dominates commercial embroidery, and the reasons are practical.
Durability. Polyester is significantly stronger than rayon. It resists breakage during high-speed machine embroidery and holds up under tension without snapping.
Colorfastness. This is the big one. Polyester thread retains its color through hundreds of wash cycles. It resists fading from UV exposure, chlorine, and detergents. A navy monogram on a white towel will still look navy after years of use.
Wash resistance. Polyester doesn't shrink, doesn't bleed, and doesn't weaken when wet. For towels, tote bags, and any textile that sees regular laundering, this matters enormously.
Modern polyester threads also offer excellent sheen. The old knock against polyester — that it looked dull compared to rayon — hasn't been true for years. Today's premium polyester threads deliver a subtle luster that sits naturally on cotton and linen without looking plastic or artificial.
Cotton: Classic but Limited
Cotton embroidery thread has a soft, matte finish that appeals to certain aesthetics. It looks understated and handcrafted, which works well for vintage or rustic designs.
Cotton thread is also comfortable to work with for hand embroidery. It doesn't have the slippery quality of synthetic threads, making it easier to control for detailed handwork.
However, cotton thread has limitations for machine embroidery on functional items. It's less colorfast than polyester. It can shrink slightly when washed, which distorts the design. And it lacks the tensile strength needed for dense, high-stitch-count logos and lettering.
For decorative hand embroidery on garments or linens, cotton has its place. For custom towels and bags that will be used daily, polyester outperforms it in every measurable way.
Why Polyester Is the Standard for Towel Embroidery
When we embroider custom names on an Ephese towel or a company logo on a Perga Essence, we use premium polyester thread exclusively. Here's why that matters for you.
Turkish towels are designed to be washed frequently. They go to the beach, the pool, the gym. They get tossed in with regular laundry. They see sun, salt, and sand. Any embroidery on them needs to survive all of that without fading, fraying, or pulling.
Polyester handles it. The embroidery on our towels maintains its sharpness and color wash after wash. That's not marketing language — it's a function of the thread material.
Rayon would start showing wear within months under those conditions. Cotton would soften and fade. Polyester keeps its form.
Thread Weight and Density: The Details That Matter
Thread type isn't the only variable. Thread weight (thickness) and stitch density also affect how your finished embroidery looks and performs.
Thread Weight
Embroidery thread weight is measured by a numbering system where higher numbers indicate finer thread. The most common weight for machine embroidery is 40wt (weight 40).
- 40wt is the industry standard. It provides excellent coverage, clean lettering, and works on most fabrics including towels and canvas.
- 60wt is finer. It's used for detailed, small-scale designs where a thicker thread would look bulky. Think small monograms or intricate logos.
- 12wt or 30wt are heavier threads, sometimes used for a bold, textured look. These work better on denser fabrics and aren't ideal for Turkish towels.
For most custom towel and tote bag embroidery, 40wt polyester delivers the best balance of visibility, detail, and durability.
Stitch Density
Stitch density refers to how closely together the stitches are placed. Higher density means more thread per square inch, which creates a more solid, filled-in appearance.
Too low, and the base fabric shows through the design. Too high, and the embroidered area becomes stiff and puckered — a real problem on soft, drapey fabrics like peshtemal cotton.
Getting density right requires understanding the fabric. A well-digitized logo accounts for the specific weight and weave of the material it will be stitched onto. This is why the digitization process matters as much as the thread itself.
How Thread Color Is Matched to Your Design
Color matching is another area where thread quality plays a role. Premium thread manufacturers offer hundreds of precisely defined colors, each with a unique reference number. This ensures consistency across production runs.
When you submit a logo or design for embroidery, the colors are matched to the closest available thread shades. High-quality thread brands maintain tight color tolerances, so a "burgundy" thread looks the same whether it was produced this year or three years ago.
This consistency matters when you're ordering in batches. If you order 50 Ephese towels in lilac with matching embroidery today and another 50 next quarter, the thread color needs to be identical. Cheap, generic thread brands don't guarantee that kind of consistency.
What to Ask Your Supplier About Thread Quality
If you're ordering custom embroidered products — whether towels, bags, or apparel — here are the questions worth asking.
What type of thread do you use? The answer should be polyester for any item that will be washed regularly. If a supplier uses rayon on towels, that's a red flag.
What brand of thread? Reputable suppliers use name-brand threads (Madeira, Isacord, or equivalent) with documented colorfastness ratings. Generic, unbranded thread is a gamble.
What's the thread weight? For most applications, 40wt is standard. If your design has very fine detail, ask whether they use 60wt for small elements.
How is the design digitized? Thread quality means little if the digitization is poor. Ask whether designs are digitized specifically for the fabric they'll be stitched on.
Do you test wash samples? Any supplier confident in their embroidery thread quality should be willing to provide a wash-tested sample. If they hesitate, consider why.
Thread Quality Is Design Longevity
The difference between embroidery that lasts and embroidery that doesn't almost always comes down to thread. It's not the most glamorous part of the process, but it's the most consequential.
Choosing premium polyester thread means your names, logos, and designs will look as sharp on the hundredth wash as they did on the first. That's the difference between embroidery and print methods like screen printing — embroidery is built into the fabric. And when the thread is right, it stays there.
Whether you're personalizing towels for a wedding, branding them for your business, or gifting them for a special occasion, thread quality is the invisible detail that makes everything else work.

Frequently Asked Questions
What is the best thread type for embroidery on towels?
Polyester thread is the best choice for embroidery on towels. It is significantly stronger than rayon, retains its color through hundreds of wash cycles, and resists fading from UV exposure, chlorine, and detergent — all conditions towels regularly encounter.
What is the difference between rayon and polyester embroidery thread?
Rayon thread has a silkier sheen and is more affordable, but it weakens and fades with repeated washing. Polyester thread is stronger, colorfast through heavy use, and wash-resistant, making it the industry standard for functional textiles like towels and bags.
Does embroidery thread fade after washing?
It depends on the thread type. Rayon thread loses color and luster relatively quickly. High-quality polyester thread maintains its color accurately through hundreds of wash cycles, which is why reputable embroiderers specify the thread brand and its documented colorfastness ratings.
What embroidery thread weight should be used for towels?
40-weight polyester is the industry standard for machine embroidery on towels and tote bags. It provides clean coverage, works well for lettering and logos, and balances visibility with durability. Finer 60-weight thread is used for very detailed or small-scale designs.
How is embroidery thread color matched to a logo?
Premium thread manufacturers produce hundreds of precisely defined colors with unique reference numbers and tight color tolerances. A reliable supplier matches your logo colors to the closest thread shade and maintains consistency across production runs so reorders look identical to the original.
