Which one is better, and why?

Polyester. The name that everyone groans at and side-eyes. It gets a bad reputation, but exactly why and what is it? Is it really that much worse than cotton, or is it just propaganda from cotton snobs?

Making its debut to the American public in 1951, polyester was introduced as a cheaper, hydrophobic fabric option to cotton. The name "polyester" refers to its chemical structure, with "poly" meaning many and "esters" the organic compounds that form its base. To get more scientific, it's made by combining ethylene glycol and terephthalic acid.

Its durable, wrinkle-free nature was attractive to the public and quickly gained popularity up until the late '70s when youths complained about the double-knit polyester suits being too coarse, thus starting the negative connotations.  

While touted as the miracle fabric, it was prone to static cling and pilling, and oil stains were often difficult to remove-something that cotton had a leg up on- and back to natural fabrics people gravitated towards.

Cotton had been around for thousands of years, making it the most reliable source of materials in terms of familiarity. Breathable, hypoallergenic, and softer than polyester, it's not surprising that we humans have kept cotton crops for that long. But just because it's natural does not mean we farm it organically or that it's environmentally friendly.

Conventional cotton aggressively uses agrochemicals, especially pesticides. The amount of water used and the runoff impacts the environment and pollutes the villages near it. Organic cotton can be farmed, but the prices are substantially higher.

So where does that leave us today?

Neither fabric is categorically superior, and the gap between them has narrowed considerably. Modern performance polyesters are softer, more breathable, and less prone to static than their '70s ancestors. Blended fabrics (typically 50/50 or 60/40 cotton-polyester) have become a popular middle ground, borrowing the softness of cotton and the durability of polyester. The question of which to choose increasingly comes down to one thing: what are you making?

COTTON STRENGTHS

Color retention over time

Moisture-wicking versions available

Lower cost at scale

Weakness:

Traps heat, less breathable

Derived from petroleum

For embroidery, DTG, and DTF — the fabric matters more than you think

If you're decorating garments -whether by needle or by ink-the base fabric is one of your most important variables. Each decoration method responds differently to the weave, texture, and fiber content of the fabric beneath it, and choosing wrong can mean wasted time, wasted product, or a finished piece that doesn't hold up after a few washes. And the quality, quality, quality of the garment makes a HUGE difference.

"The decoration is only as good as the surface it lives on."

Embroidery- Leans cotton

Embroidery thread sits on top of the fabric, hooped and stitched under tension. Cotton's tight, stable weave gives the needle consistent resistance and keeps the design crisp. Loose-knit or stretchy polyester fabrics can shift during hooping, causing distortion or puckering. That said, high-density polyester fleece and structured poly blends embroider well. The rule is stability, not fiber content. Where cotton reliably wins is on fine details: tightly woven cotton won't snag or pull the way some synthetics do.

DTG (Direct-to-Garment)-Strong cotton

DTG printing sprays water-based ink directly onto fabric and relies on the fibers absorbing it. Cotton is the gold standard here. Its natural fibers bond with the ink, producing vibrant, soft-feel prints that wash well. Polyester resists water-based ink, which means prints on synthetic blends often look faded or require specialized polyester-compatible inks. If you're printing on dark cotton, a white ink under-base is essential. Most DTG machines will technically print on polyester, but the results are noticeably inferior without pre-treating or using a specialty machine. A 100% cotton or 90%+ cotton garment is almost always the right call for DTG.

DTF (Direct-to-Film)- Either works

DTF is the great equalizer. The process involves printing a design onto a special film, applying a hot-melt adhesive powder, curing it, and then heat-pressing the finished transfer onto the garment. Because the design is transferred as a complete film layer rather than absorbed into the fibers, it adheres effectively to both cotton and polyester, as well as nylon, canvas, denim, and most blends. The caveat is texture: very rough or heavily textured fabrics can affect adhesion. On smoother fabrics, DTF transfers are durable, wash-resistant, and colorfast. This makes DTF the most versatile option for anyone working across multiple fabric types, and a strong choice for polyester performance wear where DTG falls short.

The bottom line

Cotton and polyester each have a rightful place in the fabric world. For comfort-first apparel and ink-heavy DTG projects, cotton remains the preferred choice. For performance wear, longevity, and cost-effective production at scale, polyester holds its own. For anyone decorating across a mixed inventory of garments, DTF printing is the most forgiving process, regardless of what the tag says. And if you’re looking for a sweet spot, polyester/cotton blends are the way to go.

The real propaganda isn't in favor of cotton or polyester; it's the idea that you have to pick one and stick with it. The most versatile makers know both fabrics, understand their quirks, and choose accordingly.
