What Is Microfiber Towel Made Of? Fibers, Weave and Why It Matters

Wondering what is microfiber towel made of? Learn the polyester and polyamide blend, how split fibers work, and how to pick the right towel for swimming.

Updated November 2026

A microfiber towel is made mostly from synthetic polyester and polyamide (nylon), usually in a blend of about 80 percent polyester and 20 percent polyamide. These ultrafine fibers are split and woven into a dense structure that soaks up water quickly and dries fast. This guide explains what is microfiber towel made of, how that composition works, and how to choose one that suits pool or open-water use.

The Core Materials: Polyester and Polyamide

Most microfiber towels are a polyester and polyamide blend. Polyester gives the towel its strength and resistance to shrinking and fading. Polyamide, the same family of material as nylon, adds softness and helps the fibers grip water and dirt. Manufacturers commonly specify the 80/20 ratio, though some towels use a different split, so check the label if the exact blend matters to you.

Neither material is a natural fiber. That is why microfiber towels feel different from cotton or terry: they are lighter, pack smaller, and rarely hold a musty smell when rinsed and dried properly.

How Split Fibers Create Absorbency

The key step is not the raw material alone but how the fibers are processed. Manufacturers slice each filament into much finer strands, often described as splitting, so a single square inch of towel contains a huge number of tiny fibers. These strands create many small channels that pull water into the towel through capillary action.

Fiber thickness is usually described in denier. Finer microfiber, with a lower denier, tends to hold more water per square inch. For swimmers, this means a towel that wicks water off the skin quickly, even if it feels thinner than a bath towel.

How the Weave Affects Performance

After splitting, the fibers are knit or woven into a fabric. Common constructions include:

  • Waffle weave: Open pockets trap water and speed drying, which suits lightweight travel towels.
  • Terry-style loop: Plush loops feel softer against skin and absorb more volume.
  • Suede or chamois-style: A dense, smooth surface that works well for polishing and drying glass.

The weave determines whether the towel feels plush or flat, how much it holds, and how quickly it dries. Choose based on your main task rather than the weave name alone.

Checklist: Choosing a Microfiber Towel for Swimming

  1. Check the fiber blend on the label, usually polyester and polyamide.
  2. Look for a weight or GSM (grams per square meter) rating that matches your use. Lighter towels dry faster.
  3. Pick a size that fits your routine, such as a compact towel for a gym bag or a larger one for beach days.
  4. Confirm the construction suits your task: waffle for speed, loop for comfort.
  5. Plan to wash it separately, without fabric softener, which can coat the fibers and reduce absorbency.

Common Mistakes to Avoid

  • Using fabric softener, which clogs the split fibers and weakens absorbency.
  • Drying on high heat, which can damage the synthetic fibers over time. Air drying or low heat is safer.
  • Washing with lint-heavy cotton items, since lint sticks to microfiber and is hard to remove.
  • Assuming all microfiber is equal. Blends and splitting quality vary widely.
  • Storing the towel damp, which can lead to odor even on synthetic fabric.

If you are shopping for a swim-focused towel, start with a lightweight option designed for pool and beach use. For quick drying after training, a compact towel fits easily in a bag. View on Amazon

FAQ

Is microfiber made of plastic?

Microfiber is made from synthetic polymers, mainly polyester and polyamide, which are petroleum-based plastics. They are not the same as single-use plastic bags, but the fibers do shed during washing.

What is the difference between microfiber and cotton?

Cotton is a natural fiber that absorbs slowly and dries slowly. Microfiber is synthetic and split into fine strands, so it absorbs and dries faster for its weight.

Can microfiber towels be used on skin?

Many people use them for face and body drying, especially fine-weave versions. If you have sensitive skin or a skin condition, consult a dermatologist before switching.

Conclusion

A microfiber towel is mainly polyester and polyamide, split into very fine fibers and woven for fast absorbency. Understanding the blend and the weave helps you match a towel to swimming, travel or cleaning. Wash it gently and avoid fabric softener to keep it performing well.
