Composition of Polyester Fabric
Polyester is primarily composed of a synthetic polymer called polyethylene terephthalate (PET), which is derived from petroleum. The process entails polymerizing purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) with monoethylene glycol (MEG). This reaction yields strong and versatile polyester fibers. Polyester fabrics are appreciated for their resistance to wear, stretching, and shrinking; they also dry quickly. Textile technology has also improved to enable blending polyester with natural fibers, such as cotton, thereby enhancing the feel while retaining the benefits and easy-care traits of polyester.

Environmental Impact Overview
This textile symbolizes versatility and usage, yet it poses multiple environmental problems. It is derived from petroleum, a non-renewable resource, and the entire manufacturing process of polyester is directly responsible for the emission of greenhouse gases. Polyester is not biodegradable; therefore, it will remain in the environment for years and contribute to landfill accumulation. The positive aspects of polyester garments can release microplastics into water bodies, which may have a detrimental effect on marine life and ecosystems. In contrast, recycling technologies have evolved recently to convert waste materials into recycled polyester, thereby minimizing the use of virgin raw materials and reducing environmental impact.
Environmental Impact of Acrylic
Environmental challenges are associated with acrylic, a synthetic fiber made from petroleum. The manufacturing processes for acrylic fabrics involve chemicals such as acrylonitrile, which can pose a risk to workers and the environment if not handled properly. Acrylic is another type of synthetic fiber that, just like polyester, cannot decompose and remains in landfills forever. Moreover, washing acrylic fabrics releases microplastics into waterways, which threaten aquatic life and exacerbate pollution problems. These concerns notwithstanding, efforts are underway to explore more sustainable alternatives and improve recycling options, although the technology for recycling acrylic is very complex and remains in its infancy.
Sustainability of Polyester Fabrics
Due to its durability, infamous versatility, and affordability, polyester is among the most popular synthetic fabrics. However, the environmental impacts are worth mentioning. Polyester is derived from petroleum, a non-renewable resource. Its production process has been very energy-intensive, which adds to the growing greenhouse gas emissions. Washing polyester garments, much like washing acrylics, introduces microplastics into waterways, posing serious threats to marine ecosystems. The state-of-the-art recycling technologies have also given rise to recycled polyester, mostly from post-consumer plastic bottles. Although recycled polyester is a more sustainable alternative, it does not entirely address the issue of microplastic shedding. Increasingly, efforts are being made to mitigate the environmental impact of polyester by researching the production of bio-based polyesters and investing in improved recycling infrastructure.
