    What is microfiber?

    Rowan has a new yarn in its line.  It’s called Four Seasons.  A blend of cotton and microfiber, it is soft and bouncy with a lovely hand and great stitch definition.

    The labeling says Cotton and Acrylic.  Extremely misleading.  Technically correct, but misleading.  In the same way that there are different grades of merino yarn, there are all grades of acrylic fiber, and the acrylic in Four Seasons is microfiber and bears about as much resemblance to acrylic as goat hair does to cashmere.  

    Let’s take a look at what microfiber is and what it does to yarn, because you’re going to see it everywhere.  

    What is microfiber? 

    Microfibers are extra-fine filaments, typically made of polyester, polyamide, acrylic, modal, lyocell or viscose.. To be labeled a microfiber, the strand must be less than 10 microns in diameter.  For reference fine merino is about 20 microns, and cashmere is less than 14 microns, so microfiber is really, really fine. 

    What does microfiber do for a yarn? 

    Microfiber enhances a yarn’s look and feel

    Microfibers have a silky soft, luxurious hand. Adding them to a yarn increases the yarns luster, softness, and drape.  

    Microfibers are lightweight

    The addition of microfibers lightens a yarn making for a garment that weighs less and is more comfortable on your body

    Microfibers are strong and elastic

    Microfibers increase the tensile strength of a yarn, which means it’s less likely to break.  Microfibers in yarn help garments hold their shape and spring back better after being worn. Microfibers also help reduce linting and pilling.

    Microfibers make cotton fabric more comfortable to wear. 

    Microfibers are super-absorbent, absorbing over 7 times their weight in water. Microfiber’s tiny capillaries that transfer the moisture outside of the fiber to the air where it can be evaporated.  Microfiber dries in one-third of the time of ordinary fibers.

    What are the downsides to microfiber in yarn?

    While microfibers have lots of benefits, it’s important to note where microfibers’ weaknesses lie.  First, they are heat sensitive. So you’re going to want to wet block your swatches and fabric pieces rather than using steam.  After the garment is together, dry wash gently in cool water and lay it flat to dry.

    The making of yarn is a complicated matter, as is choosing yarn for a garment you want to create.  There are all kinds of construction methods, fiber blends, and more.  One is not better than the other, they're just different.  What's perfect for one garment might be perfectly awful for another.  But the more you know about yarn and the deeper your understanding of the different characteristics of each, the better you'll be able to choose what's right for you and your project.
