What You'll Learn
Microfiber is made of plastic
Microfiber is a controversial element of fabric that has been the subject of scrutiny in recent years due to its plastic composition. While microfiber fabrics may feel like cloth, they are primarily made of plastic, specifically plastic polymers spun into a cloth. This fabrication process gives microfiber its superior ability to pick up dirt and dust, making it a popular choice for cleaning materials and linens. However, the plastic composition of microfiber has also raised concerns about its environmental and health impacts.
Microfiber is a type of microplastic, which is a plastic particle smaller than 5 millimeters in length. These tiny plastic fibers can be released from synthetic materials during washing, contributing to microfiber pollution in water sources and the ocean. A single piece of synthetic material, such as microfiber, can release thousands of fibers into the water supply with each wash. This has led to an estimated 3.5 quadrillion microfibers being released into the ocean annually in North America alone.
The small size of microfibers makes them nearly impossible to capture once they enter the environment. As a result, they can be ingested by marine life and work their way up the food chain, eventually ending up on our plates. Microfibers have been detected in various foods, beverages, and even the air we breathe. While the health impacts of ingesting microplastics are still being studied, there is indirect evidence suggesting potential toxic effects. For example, plastics are known to absorb toxic chemicals, and the ingestion of microplastics could lead to the consumption of these harmful substances.
Additionally, the shape of microfibers may increase the likelihood of blockages in the digestive tract, and the chemicals attached to the fibers can pose additional health risks. Studies suggest that inhaled polyester and nylon microfibers may impair the lungs' ability to repair themselves. Furthermore, microfibers can release chemicals during use and laundering, contributing to air and water pollution. The non-biodegradable nature of microfiber further exacerbates the issue, as these synthetic fibers can persist in landfills for over 200 years, adding to plastic waste and pollution.
While microfiber has advantages in terms of durability and cleaning performance, its plastic composition raises environmental and health concerns. The release of microfibers during washing contributes to plastic pollution, and the small size of these fibers makes them challenging to capture and remove from the environment. As a result, microfibers can end up in our food and water sources, potentially impacting human health. More research is needed to fully understand the extent of these impacts, but the presence of microplastics and microfibers in our ecosystems is a significant issue that requires attention and sustainable solutions.

Microfiber pollution
Microfibers are tiny plastic strands that come off synthetic clothing when washed. They are thinner than a human hair and can pass through wastewater treatment filters, eventually infiltrating oceans, rivers, and soil, causing microfiber pollution. Each person releases approximately 300 million microfibers per year by doing laundry, with 35% of this microplastic pollution coming from washing synthetic textiles. These microfibers have been found in Arctic waters, the Mariana Trench, both poles, and the Himalayas, demonstrating their widespread presence in the environment.
The health risks associated with microfiber pollution are still being studied, but there is indirect evidence of potential harm. Microfibers can act as sponges for harmful chemical pollutants, including carcinogenic dyes, which can then be ingested by humans and animals. These chemicals can cause gut blockages, injuries, and changes to oxygen levels, as well as accumulate in the liver and kidneys, as seen in lab mice. Inhaled polyester and nylon microfibers may also impair the lungs' ability to repair themselves.
To address microfiber pollution, individuals can take small but impactful actions, such as using microfiber-filtering bags or balls in washing machines or purchasing clothing made from natural fibers like organic cotton, wool, linen, hemp, or silk. However, even "100% natural" clothing may contain chemical additives, so transparency in the textile industry is crucial. The recycling process for synthetic fibers is challenging due to their non-biodegradable nature, and they can persist in landfills for over 200 years, further contributing to plastic waste and pollution.
While individual efforts are essential, the microfiber pollution problem is massive and global. The plastic microfibers released during laundry contribute significantly to the world's oceans' plastic pollution, with an estimated 2.2 million tons entering the ocean annually. This crisis is not just about visible plastic waste like bags and bottles but also the pervasive presence of microplastics in the environment, which are ingested by marine life and ultimately enter the human food chain.
As researchers continue to study the health and environmental impacts of microfiber pollution, it is clear that this issue warrants urgent attention and collective action to mitigate its potential harm to ecosystems and human health.

Microfiber's health impact on humans
The health impact of microfibers on humans is an emerging area of research. While the full extent of their health consequences is not yet known, there are serious concerns about the potential risks associated with exposure to microfibers.
Microfibers are tiny plastic strands that are shed from synthetic clothing during washing. They are not biodegradable and persist in the environment, ending up in soil, rivers, and oceans. These microfibers have been detected in various ecosystems, including marine sediments and organisms, and have also been found in human food, tap water, and even beer.
The primary route of human exposure to microfibers is through inhalation, which poses significant risks to human health. Inhaled microfibers can enter the pulmonary epithelium and may interfere with membrane transporter activity. Studies have shown that inhaled polyester and nylon microfibers can impair the lungs' ability to repair themselves, leading to potential long-term damage.
Additionally, microfibers can enter the human body through ingestion. While the human excretory system eliminates a significant portion of ingested microplastics, it is estimated that people consume about five grams of plastic each week. The health risks associated with ingestion are still being studied, but there are concerns about the potential impact on various organs and systems, including the placenta, liver, muscles, and brain.
Microfibers have also been found to contain a range of chemicals, including BPAs, which are known to cause health issues. These chemicals can leach out and accumulate harmful pollutants, further exacerbating the potential health risks associated with microfiber exposure.
While the research on the health impacts of microfibers is ongoing, the available evidence suggests that their presence in the environment and human bodies is a cause for concern. The indirect evidence, as explained by Sherri Mason, a professor of chemistry and leading researcher, indicates that plastics absorb toxic chemicals, and the health impact of those chemicals is well-established.
