Is Microfiber Polyester? Fiber Types, GSM & Uses for Buyers
Is microfiber polyester? Usually, yes. Microfiber describes how fine the fiber is (under 1 denier per filament, roughly under 10 micrometers), not what it is made of, and most commercial microfiber is either 100% polyester or a polyester-polyamide (nylon) blend, most often 80/20. The fine filaments are what make the fabric soft, dense and absorbent.
Key Takeaways
- Microfiber is a fiber-fineness class, not a fiber. Most is 100% polyester; cleaning cloths and towels often use polyester/polyamide blends such as 80/20 or 70/30.
- The base fiber sets the job: 100% polyester for bedding, apparel and upholstery; polyester/polyamide split microfiber where absorbency matters.
- Typical weights: about 70-120 GSM for bedding, 100-180 GSM for activewear, 200-350 GSM for upholstery, 200-400 GSM for cleaning cloths.
- Versus regular polyester, microfiber is softer, denser and more absorbent; standard polyester is usually cheaper and a little more rigid.
What Is Microfiber Polyester?
Microfiber polyester is a fabric made from polyester filaments spun finer than 1 denier per filament, which is under 10 micrometers in diameter and much thinner than a human hair. Because the filaments are so fine, a given fabric weight contains many more of them, giving a smoother surface, a softer hand and a denser structure than standard polyester.
The label covers two common constructions:
-
100% polyester microfiber: the most common type. Used for bedding, brushed fabrics, activewear, linings and upholstery. Also called "peach skin" or brushed microfiber when the surface is sanded.
-
Polyester/polyamide (nylon) microfiber: usually 80/20 or 70/30. Each filament is split during processing, which raises absorbency and wiping performance. This is the standard base for cleaning cloths and towels.
Polyester itself is polyethylene terephthalate (PET), a petroleum-based polymer. Polyamide is a separate synthetic polymer, which is why a polyester/polyamide microfiber is a blend rather than "just polyester." For related options, see our guides to polyester-nylon blend fabric and polyester fabric for upholstery.
What Are the Key Properties and Moisture Wicking Abilities of Microfiber Polyester?
Fine filaments give microfiber a consistent set of properties: softness, density, quick drying, colour depth, and better breathability than standard polyester. Which of them matters depends on the end product, so it helps to read them against the application rather than as a general list; for more structured garments and uniforms, some buyers still prefer durable 100% polyester Mini Matt fabric in place of microfiber.
| Property | What it means in practice | Why buyers care |
|---|---|---|
| Softness | Smooth, silky hand from very fine filaments | Skin-contact products: sheets, pillowcases, activewear |
| Density | Tight structure with small gaps between filaments | Wind resistance, stain resistance, low pilling when well finished |
| Moisture handling | Standard polyester generally repels water and is tailored for moisture-wicking sportswear; split polyester/polyamide microfiber absorbs more | Sports tops, bedding, wiping cloths |
| Quick drying | Polyester base fiber has very low moisture regain (about 0.4%) | Faster drying, lower mildew risk in storage and transit |
| Colour | Takes disperse dyes deeply and holds colour through washing | Consistent shades across reorders |
| Light weight | Good coverage at low GSM | Lower freight weight per metre |
Typical characteristics. Actual performance depends on yarn denier, knit or weave construction and finishing.
There are trade-offs. Microfiber is generally more breathable because it lets more air pass through than tightly constructed regular polyester fabrics, while polyester is less breathable as a breathable fabric because its closely woven fibers limit airflow. Microfiber can build static, attracts lint and oils more readily than coarser fabrics, and holds odours if washed with fabric softener, which coats the filaments. None of these rule it out; they are the points to check with a supplier on finishing (anti-static, brushing, wicking treatments) before bulk orders, especially if you are also sourcing technical materials like 60gsm PP nonwoven fabric for medical or packaging uses.
How Does Microfiber Differ From Regular Polyester?
Both are polyester, so the real difference in microfiber and polyester is filament fineness and what that does to hand, density and absorbency. Regular polyester filaments are thicker, which makes a firmer, more synthetic-feeling fabric that can have a softer feel gap in comparison and may feel stiffer and rougher against the skin than microfiber. Microfiber trades a little extra cost for a softer, denser result. The table below shows a few key differences in polyester and microfiber.
| Factor | Microfiber polyester | Regular polyester |
|---|---|---|
| Filament fineness | Under 1 denier per filament (under about 10 µm) | Above 1 denier per filament |
| Hand | Soft, smooth, silky | Firmer, more synthetic feel |
| Absorbency | Higher, especially in split polyester/polyamide types | Lower |
| Density / coverage | High coverage at low GSM | Needs more weight for the same opacity |
| Durability | Good abrasion and wash life; fine surface can pill if poorly finished | Good; thicker filaments can resist surface wear well |
| Relative cost | Higher | Lower |
| Typical uses | Bedding, activewear, upholstery, cleaning cloths | Linings, workwear, outdoor and general-purpose fabrics |
Typical comparison. Both fabrics can be made in a wide range of qualities, so confirm with a physical sample.
Durability is the point most often over-simplified. In polyester vs microfiber comparisons, polyester is generally more durable than microfiber at the fiber level, though both fabrics last well when properly constructed and finish quality, yarn denier and weight matter more than the label. Ask for abrasion and pilling test results on the exact quality, rather than relying on a general claim.
What Is Microfiber Polyester Used For, Including Polyester and Microfiber Sheets, and at What GSM?
Microfiber polyester is used wherever softness and coverage at low weight matter: bedding, activewear, upholstery and cleaning products are the four volume categories. Each sits in a different weight band, so GSM is the first number to confirm when comparing quotes, in the same way that you would compare weights and yarn structures when sourcing checked fabrics for school uniforms.
| End use | Typical base | Typical weight | Why microfiber fits |
|---|---|---|---|
| Bedding (sheets, pillowcases, covers) | 100% polyester, brushed | 70-120 GSM | Soft hand, wrinkle resistance, easy care; microfiber bedding is often preferred in bed sheets for a softer feel and better airflow than standard polyester sheets |
| Activewear and base layers | Polyester or polyester/elastane | 100-180 GSM | Light, quick-drying, good wicking |
| Upholstery and sofa fabric | 100% polyester, suede or velvet-type finish | 200-350 GSM | Dense surface, stain resistance, rich colour; options include super soft polyester Jaguar sofa fabric that keeps its hand after repeated washing |
| Cleaning cloths and towels | 80/20 or 70/30 polyester/polyamide | 200-400 GSM | High absorbency, traps dust, non-scratching |
Typical ranges only. Confirm weight, width and finish on the specific quality.
For upholstery, it also helps to match microfiber against other premium upholstery fabric options such as cotton, linen, leather and velvet, so that comfort and durability suit the end use.
How Should Microfiber Polyester Be Cared For?
Microfiber is easy to care for if the filaments are not coated or overheated. Laundering microfiber and polyester can release microplastic fibers, and washing polyester releases about 10 million microplastic fibers per wash. Cold or lukewarm machine wash on a gentle cycle, with regular detergent, is enough for most products, and similar low‑maintenance care applies to plush Holland velvet polyester upholstery. This guidance is worth including on product labels and care cards.
-
Wash: cold to 30-40°C, gentle cycle, regular detergent, and ideally with other microfibers to limit lint pickup; gentler washing also helps reduce wear and fiber shedding.
-
Avoid: fabric softener and bleach. Softener coats the fibers and reduces wicking and absorbency; bleach weakens the fabric.
-
Dry: low-heat tumble dry or line dry; avoid high temperatures because lower heat helps reduce wear and fiber shedding. High heat can glaze the surface, which is particularly important for lightweight sheers like polyester chiffon fabric.
-
Stains: blot promptly and treat with mild soap; for oil-based stains, work in a little dish soap before washing.
-
Storage: keep dry and cool, and hang or lay flat rather than folding in sharp creases; for sewn products, pair microfiber with high‑quality 40/2 100% spun polyester sewing thread to maintain seam strength through repeated laundering.
That shedding can contribute to microplastic pollution in oceans and waterways, so specifying durable polyester sewing threads and gentler wash conditions can help extend product life and reduce replacement frequency.

Frequently Asked Questions
Is microfiber polyester? Usually, yes. Microfiber means fibers finer than 1 denier per filament, and most microfiber fabric is 100% polyester. Cleaning cloths and microfiber towels often use a polyester/polyamide (nylon) blend, commonly 80/20 or 70/30; in split weave versions, the material traps microscopic particles, bacteria, and grime within its split-fiber matrix, so check the fiber content on the spec sheet.
How is microfiber polyester different from regular polyester? The difference is filament thickness. Microfiber filaments are under 1 denier, giving a softer, denser fabric, while regular polyester is firmer and usually cheaper. In cleaning and towel applications, it absorbs liquids and can absorb water up to seven times its weight. Both are polyester, and durability depends more on construction and finish than on the label.
What GSM is microfiber polyester? Typical weights run from about 70-120 GSM for bedding and 100-180 GSM for activewear to 200-350 GSM for upholstery and 200-400 GSM for cleaning cloths. Confirm weight, width and finish on the specific quality before ordering.
How do you care for microfiber polyester? Wash cold to 30-40°C on a gentle cycle with regular detergent, avoid fabric softener and bleach, and dry on low heat or line dry. Treat stains promptly and store dry and cool.
Conclusion
Microfiber polyester is a polyester fabric defined by fineness, and the useful buying details are the fiber base, the blend ratio and the GSM. 100% polyester microfiber covers most bedding, activewear and upholstery, while 80/20 or 70/30 polyester/polyamide serves cleaning products.
