Synthetic fibers have seamlessly become woven into the fabric of our daily lives. In 1940, only 5,000 metric tons of synthetic fiber were produced globally. By 2019, this figure had increased to 76.5 million metric tons. From athletic wear to haute couture, synthetic fiber has grown to become a mainstay.
However, beneath the glossy allure, there's cause for concern. From the manufacturing process to the disposal of these synthetic fibers, there are a number of ways in which they can have a negative impact on the environment.
Synthetic fibers are man-made textile materials created through chemical processes. Unlike natural fibers derived from plants or animals, synthetic fibers are produced entirely in laboratories. They are engineered to possess specific characteristics such as strength, durability, elasticity, and wrinkle resistance, making them suitable for various applications in the fashion and textile industry.
The production of synthetic fibers involves transforming raw materials, typically derived from fossil fuels like petroleum, coal, or natural gas, into polymers. These polymers are then spun or extruded into fine filaments or threads, which are further processed and treated to enhance their properties.
Synthetic fibers come in different types; each engineered to possess specific characteristics and fulfill various applications in the fashion and textile industry. Polyester, acrylic, and nylon are some of the most popular types of synthetic fibers.
Synthetic fibers - the fabric of our lives?
Synthetic fibers come with their benefits. Their adaptability allows them to be engineered to meet specific performance requirements, making them suitable for various applications.
Moreover, synthetic fibers are known for their cost-effectiveness. Compared to natural fibers, such as cotton or silk, synthetic fibers can be produced at a lower cost due to their manufacturing process and the abundant availability of raw materials. This affordability makes synthetic fibers a popular choice for mass production in the fashion industry.
Despite the benefits of synthetic fibers, they also come with a set of significant drawbacks, particularly concerning their environmental impact, health risks, and energy consumption.
One of the most pressing concerns is the non-biodegradability of synthetic fibers. Unlike natural fibers that break down over time, synthetic fibers are typically derived from petroleum-based sources and are resistant to decomposition.
Additionally, the shedding of microfibers during washing contributes to the growing issue of microplastic pollution in oceans and waterways. A report from the International Union for Conservation of Nature estimated that almost 35% of all microplastics in the ocean come from the laundering of synthetic textiles.
The manufacturing processes of synthetic fibers also raise environmental concerns. These processes involve using various chemicals, such as solvents and dyes, which can adversely affect ecosystems if not properly managed. It can take up to 200 tonnes of fresh water to produce a tonne of dyed fabric.
There are potential health risks associated with synthetic fibers. Some synthetic fibers, especially those treated with flame retardants or other chemical additives, can release harmful substances when in contact with the skin or when exposed to high temperatures.
These substances, such as formaldehyde or volatile organic compounds (VOCs), can adversely affect human health, potentially causing skin irritation, respiratory issues, or allergic reactions. Phytoestrogens, emitted by polyester, for example, act as endocrine disrupters and also cause certain types of cancers.
The production of synthetic fibers is energy-intensive, requiring significant amounts of electricity. The extraction and processing of raw materials, the conversion of polymers, and the various stages of fiber production all contribute to high energy consumption. This increased energy demand contributes to carbon emissions and the depletion of finite energy resources, further exacerbating the environmental impact of synthetic fiber production.
Time to transition towards non-toxic and low-carbon fibers?
Are we stuck with synthetic fibers? No, there are indeed alternatives.
Biodegradable synthetic fibers are a category of synthetic fibers designed to address the environmental concerns associated with traditional non-biodegradable synthetic fibers.
Unlike conventional synthetic fibers, which are derived from petroleum-based sources and are resistant to decomposition, biodegradable synthetic fibers are engineered to break down naturally over time through biological processes.
These fibers are typically made from renewable sources such as plant-based materials or biopolymers derived from sustainable feedstocks. They undergo manufacturing processes that ensure their biodegradability while still maintaining desirable characteristics such as strength, durability, and versatility.
Here are some examples of bio-degradable synthetic fibers:
Natural fibers, like cotton and wool, are one such alternative. They come from renewable sources and do not have the drawbacks associated with synthetic fibers.
The future of fashion lies in embracing ethical principles and adopting sustainable practices throughout the supply chain. From responsible sourcing of materials to eco-friendly production processes and mindful consumption, every step counts. Brands must recognize their power and responsibility in shaping a more sustainable and ethical future.
