Milliken’s New High-Performance Fabric Lets Users Breathe Deeper

Milliken releases a high-performance fabric that uses natural alternatives to fluorine and formaldehyde finishes. Here, i+s dives in deep to the material science that made it possible.

There are a lot of concerns these days about comprises the items we use every day. As consumers become more educated about the ways in which products are made and manufacturers look at the effects of t chemicals, more and more often natural solutions are requested.

Enter Breathe by Milliken. The new performance fabric provides exceptional stain resistance as naturally as possible. According to LeAnne Flack, marketing manager at Milliken, “The importance of Breathe is to [perform] with a minimal amount of chemistry. Really getting back to nature and creating [a fabric that is] fiber-forward.”

Spearheaded by Flack and Dr. Emily W. Michaels, Ph.D., research manager of engineered performance products at Milliken, the two moms aimed to create a product that could withstand the wear and tear of kids, pets, and other everyday use without harming indoor air quality.

“There’s such a trend in the marketplace of regulatory knowledge and being socially responsible with the materials that we use,” Michaels said. “That’s something that Milliken has always taken very seriously as long as the company has been in existence. One of the primary founding principles has been to be a good environmental partner and a good social partner with all of the consumers that we work with.”        


Here, i+s helps explain the more scientific language used to explain the inner workings of Breathe by Milliken.


What is it?
Breathe is a performance fabric that is free of fluorine and added formaldehydes. It doesn’t emit VOCs which can harm indoor air quality. Made of natural or recycled fibers and a plant-based water repellent, it can repel or make many everyday stains easily cleanable.

How did it come about?
Noticing a hole in the market for products that are both high-performing and sustainable, Flack and Michaels decided to head to the lab to create a new line for Milliken. “It was a lot of lab work,” Flack noted. “We didn’t really see something [on the market] that you could have on cotton as well as thick polyesters that was fluorine-free.”

What’s the importance of being fluorine free?
While fluorine is a naturally occurring element that has benefits to humans in small amounts, the types of fluorine that are found in commercial products aren’t the same as what one would find in their toothpaste. (Fluoride found in toothpaste are fluorine compounds.)

Perfluorinated chemicals (PFCs) are stain-, water-, and grease-repellent compounds. While manmade and found in a wide range of consumer products, they are made up of carbon-fluorine bonds which are among the strongest chemical bonds found and have a high half-life in the human body. There has been growing concern about our exposure to VOCs like PFCs and in November 2017 perfluorooctanoic acid (PFOA) and perfluorooctane sulfate (PFOS) were added to California’s proposition 65—the Safe Drinking Water and Toxic Enforcement Act which makes consumers aware of chemicals known to cause cancer, birth defects, or other reproductive harm.

Because of the concern for our exposure to VOCs such as PFCs, Breathe was engineered to resist most stains without their inclusion. (Due to the nature of oils, only PFCs are found to resist oil-based stains at the moment. Oil stains can be cleaned off of Breathe.)

For which markets is it ideal?
Milliken created Breathe for the residential market. However, it is a performance fabric, so it can withstand wear and tear and repels both water and non-oil-based stains without the use of fluorine and fluorine derivatives. Therefore, it can be used in additional markets such as low-impact hospitality or office spaces. It is not intended for outdoor use.

How was it made?
This collection was created by looking for a natural solution to high-performance fabrics, right down to the yarn fibers. From there, a wide variety of compounds were tested to discover the best repellency solution.

“There are different classes of chemistry that provide repellency,” Michaels explained. “There are the fluorine class which are heavily scrutinized; there are waxes and hydrophobic emulsions that provide repellency. It’s all about putting the chemistry down that can provide the right chain length, so that the water can bead up and roll off. Those are the things we look at in the lab. We’ll look at surface tension and contact angles. So when you think about things that will provide repellency, you think about things that are naturally anti-water, like a wax. It will lead you down to different categories of compounds.”
From there, the Milliken team tested hundreds of combinations before arriving at their final plant-based solution.

What certifications does it pass?
Every product in the Breathe collection has been GREENGUARD GOLD certified. Additionally, they pass all third-party industry protocols for water repellency, soil release, spot cleaning, colorfastness, abrasion resistance, and piling, as well as CAL117 (CA TB 117-2013: Cover fabric flammability) requirements without flame-retardant chemicals.
