What Is Microfiber? Material, Uses & Towel Types

What is microfiber made of?

Most microfiber cleaning towels use polyester and polyamide. The blend describes their proportions: 80/20 means 80% polyester and 20% polyamide; 70/30 means 70% polyester and 30% polyamide. Other blends include 85/15 and 75/25, and some microfiber fabrics are 100% polyester.

The composition matters, but it is only part of the story. Filament fineness, splitting, fabric construction, and finishing also affect how a towel feels and performs. A blend label alone does not tell you whether a towel suits delicate paint, glass, or heavy cleaning.

What does “denier” mean?

Denier measures linear density: one denier is one gram per 9,000 meters of fiber. It is a measure of mass relative to length, rather than a fixed diameter. Fiber material and shape affect the relationship between denier and thickness.

When discussing yarn, distinguish the size of the whole yarn from the fineness of its individual filaments. Our guide to microfiber yarn explains why that distinction matters.

How does a microfiber cloth work?

Fine filaments provide a large amount of surface area. In split microfiber, a composite filament separates into smaller segments, creating more fine edges and spaces that help collect particles. Water also moves through the spaces between fibers by capillary action.

The fabric structure determines how those fibers meet the surface. A short pile can offer a controlled wipe, while long loops can hold more water. That is why the microfiber towel you choose for drying a car may be different from the one you use for a final glass wipe.

How is microfiber made?

The exact process depends on the yarn and finished product. For a typical split microfiber cleaning towel, the main stages are:

1. Make the filaments. Polymers such as polyester and polyamide are extruded into fine filaments, including composite filaments designed to split.
2. Prepare the yarn. Filaments are brought together into yarn with the specifications needed for the fabric.
3. Knit or weave the fabric. Machinery creates the fabric structure, pile, and target weight.
4. Dye, split, and finish. Processing develops the color and separates splittable filaments into finer segments. The sequence and treatment vary by material.
5. Cut and construct the product. Fabric is cut to size and finished into towels, mitts, applicators, pads, or other cleaning tools.

Splitting separates components of a filament; it does not simply punch microscopic holes in the fiber. Not every microfiber fabric is split, and the word “microfiber” alone does not specify the manufacturing method.

Types of microfiber towels and what they are used for

“Weave” is often used as a general name for a towel’s surface structure, even when the fabric is knitted. Pile describes the raised fibers or loops. Use the examples below to match construction to a task.

Other constructions include plush, two-pile, pearl, suede, chenille, and mesh. Explore the differences in our guide to microfiber pile and weave.

Does higher GSM mean better microfiber?

GSM means grams per square meter—the fabric’s mass per unit area. It does not measure filament fineness or establish whether a towel is right for a task. A heavy drying towel and a lighter glass cloth serve different purposes.

Start with the job, then consider blend, pile, size, edges, and how the towel performs. Read what GSM means and how GSM, blend, and pile relate to towel quality.

Microfiber vs. cotton: what is the difference?

Cotton is a natural plant fiber; the microfiber used in detailing towels is synthetic. Cotton towels absorb water, too. Microfiber cleaning cloths combine fine filaments with a fabric structure designed for particle pickup, wiping, or drying.

For car care, choose a towel made for the surface and task. Material alone does not guarantee a streak-free or scratch-free result: cleanliness, construction, cleaner choice, and technique all matter. Wash microfiber separately from cotton and other lint-shedding fabrics so it does not collect their loose fibers.

How to care for microfiber towels

Wash new towels before first use. Sort used towels by job and contamination, use an appropriate detergent, rinse thoroughly, and follow the care label. Skip fabric softener and dryer sheets, and air dry or tumble dry on low heat when permitted.

Microfiber FAQs

What is a microfiber towel?

A microfiber towel is a towel made with very fine synthetic filaments. Cleaning versions commonly use polyester and polyamide. Their blend, pile, weight, and construction vary to suit different jobs.

Is microfiber plastic?

The polyester and polyamide used in typical microfiber cleaning towels are synthetic polymers—types of plastic. Microfiber describes fiber fineness, rather than one specific polymer.

Are all microfiber towels the same?

No. Two towels with the same blend or GSM can have different yarn, pile, edges, and finishing. Compare their intended use and performance rather than choosing by one number.

Can microfiber scratch car paint?

Yes. Trapped grit, hard edges, hardened product, or poor technique can cause scratches. Use a clean towel intended for paint, inspect it first, and test your process on a small area.

Can microfiber towels be reused?

Many can be washed and reused when their care instructions allow it. Check for remaining debris and hard spots after washing. Cured coating or embedded contamination can make a towel unsuitable for delicate surfaces.
