Why Microfiber?

This isn’t a topic a lot of people spend a lot of time contemplating, we admit. Honestly, on the surface it’s not near as important as condom vs. no condom, ball gag vs. no ball gag, or Obama vs. Trump, but if you are a sexual enthusiast (like we are!), it’s worth reading on and discovering that there are a couple of notable differences that you should consider when purchasing aftercare towels.

Is microfiber safe on your sensitive bits?

Microfiber cloth is made of the same synthetic material that much of our clothing is made of: polyester blend fabric. This material has been proven safe for decades as a skin contact safe material used in the textile industry, and as such is perfectly safe for use as an after sex clean up towel. In fact, it’s unique ultra absorbent qualities make it especially suited for cleaning up the naughty messes we love to make!

Our choice at AnnaRae to use microfiber material for our sex clean up towels was a careful and thoughtful decision. We refuse to sell a product we don’t use and love on a daily basis. We have provided both some technical details below as well as some general information. Be sure and check out the graphics at the bottom of the post for visual reference as well as the fact check links.


  1. Is breathable, gentle enough that it won’t scratch surfaces and very inexpensive to purchase
  2. Pushes dirt and debris rather than picking it up; this is largely due to the shape of the individual organic fibers
  3. Is made of organic materials that can harbor odor or bacteria; harsh disinfectants must be used to properly clean cotton fiber cloths
  4. Requires a break-in period to disperse the cottonseed oil and achieve its maximum softness. The cottonseed oil is then slowly stripped away via the laundering process, resulting in the rough texture that well-used cotton towels are known for
  5. Dries slowly, requiring greater energy and time
  6. Leaves lint behind
  7. Is better on rough surfaces that would damage a microfiber cloth


  1. Is highly absorbent (it can hold up to seven times its weight in water)
  2. Is effective at actually picking up and removing soil from a surface
  3. It has a long lifespan when properly used and maintained
  4. Is lint-free
  5. Has the following health care benefits:
  • A study by the U.S. Environmental Protection Agency found that extremely fine (.38 micrometer diameter) microfiber removes up to 98 percent of bacteria and 93 percent of viruses from a surface using only water. Cotton, on the other hand, removes only 30 percent of bacteria and 23 percent of viruses.
  • “Microfiber is most effective at removing germs and bacteria when you’re disinfecting,” says Jonathan Cooper, director of environmental and linen services at Orlando Health Central Hospital, Ocoee, Florida. “We’ve done ATP tests with both microfiber and cotton and we verified we were doing a much better removal of bacterial with microfiber.”  Cooper says the hospital has seen a reduction in its overall infection rates since it dumped cotton in favor of microfiber products four years ago.

What is microfiber?


Microfiber is a made from spun polyester polymer (plastic) material via a process that produces individual strands that are approximately 10 times smaller in diameter than an average human hair. The average human hair is about 0.004 inches in diameter, while the average diameter of a microfiber strand used in the production of the fabric used in AnnaRae products is approximately 0.0003 inches. By comparison, the diameter of high-quality cotton fiber averages approximately 0.0009 inches or 3X that of microfiber.

From a technical industry-speak perspective, the term “microfiber” refers to any fiber that is smaller than 1.0 denier, and a denier is the textile unit of measure where 9000 meters of a fiber weighs 1 gram. A single strand of silk that is 9000 meters long weighs very close to 1 gram, and microfiber weighs less than that!
The microfiber fabric that AnnaRae uses for the production of our aftercare towels is made from an 80% polyester 20% polyamide (nylon) blend that is 100% microfiber with no cellulose fiber include.
Why is it superior to other fabrics?

Microfiber is more absorbent per unit weight of fabric than any natural fiber. Microfiber can absorb up to 8X its weight in a liquid due to the increased surface area created by the shape of the fiber itself.
