What You'll Learn
Dacron's development and history
Dacron, also known as polyethylene terephthalate (PET), is a synthetic polymer developed by DuPont in the 1950s. It is a type of polyester fibre widely used in the textile industry for its durability, resilience, and versatility.
DuPont first introduced the material in 1951, marketing it as a lightweight, durable fabric that was resistant to wrinkles, creases, abrasion, and dry-cleaning chemicals. The company touted its suitability for clothing, and within weeks of its debut, Dacron shirts, blouses, and suits were available in stores. The fabric was also used in medical devices, with the 1966 Kantrowitz ventricle, a predecessor of the artificial heart, being made from a Dacron tube.
Dacron is made through a process called polymerization, in which ethylene glycol and terephthalic acid (or dimethyl terephthalate) are chemically reacted to create a polymer. This polymer is then spun into fibres, which can be further processed into various textile products. One of the key advantages of Dacron is its strength and durability, making it ideal for applications that require long-lasting, resilient textiles. It is also versatile, with different characteristics such as high or low stretch, stiffness, or softness, that can be manufactured depending on the intended application.
Despite its popularity, Dacron has come under scrutiny for its environmental impact. As a petroleum-based plastic, it is not the most environmentally friendly fabric. However, efforts have been made to improve its sustainability, with some manufacturers producing Dacron from recycled PET bottles to reduce waste and lower its carbon footprint. Recycled polyester, while not the most sustainable fibre, has a much lower environmental impact than virgin polyester made from oil.

Its use in clothing
Dacron, also known as polyethylene terephthalate (PET), is a type of polyester fibre. It is a synthetic, petroleum-based plastic polymer material. It is widely used in the textile industry, especially for clothing, due to its versatility, durability, strength, and moisture-wicking properties. It is also used in upholstery, bedding, pillows, and cushions.
Dacron is a brand name for a type of polyester fibre, developed and introduced by the American manufacturer DuPont in the 1950s. It is known for its strength, durability, thermal comfort, and resistance to abrasion, shrinking, and wrinkles. It is also hypoallergenic, non-absorbent, mildew-resistant, and easy to clean and care for. These properties make it ideal for blending with other natural fibres such as cotton or wool, enhancing the performance and durability of fabrics.
Dacron is used in a large variety of garments, including shirts, blouses, dresses, pants, jackets, and undergarments. It is also commonly used in high-performance fabrics, such as sailcloth and cover cloth, and is available in a range of weights and constructions. It is often blended with elastane or spandex to increase its elasticity.
Despite its popularity, Dacron has a negative environmental impact. It is not biodegradable and can take hundreds of years to decompose, releasing toxic chemicals and greenhouse gases as it breaks down. However, it can be recycled and remoulded to create new products, reducing the need for new resources. Recycled polyester, for example, creates less waste and reduces carbon dioxide emissions.
To care for Dacron clothing in a more sustainable way, it is recommended to wash in cold temperatures, preferably by hand, and to avoid using strong detergents and high washing speeds. Hanging clothes to dry on a line is also more energy-efficient than using a dryer and helps to preserve the quality of the garment.

Its use in medical devices
Dacron, also known as polyethylene terephthalate (PET), is an early form of plastic that is widely used in everyday products. It is also the first type of plastic to be considered recyclable. However, it is made from petroleum-based plastic, which is not the most environmentally friendly material.
Dacron has been used in the medical field since the 1950s, when it was first used for arterial grafts. Its strength, durability, thermal comfort, and moisture-wicking properties make it ideal for medical applications.
Dr. Michael DeBakey, known as "the father of vascular surgery," was a pioneer in using Dacron for medical purposes. In 1954, he implanted Dacron into a patient at the Houston VA Medical Center for the first time. DeBakey specialised in the study of aortic aneurysms and used Dacron to create a prosthetic graft to fix weakened arteries. In 1964, he published an 8-year study of 67 patients where Dacron vascular grafts were used for aortic aneurysm and vessel bypass. Dacron proved to be a useful and long-lasting material for this purpose, and it is still widely used today.
Dacron has also been used in other medical devices such as braided, corrugated aorta tubes, vascular prosthetics, and clamshell devices. In the clamshell device, a double umbrella composed of four stainless steel arms is covered with a polyester (Dacron) meshwork. This device is used to treat atrial septal defects and offers the potential for minimal blood-flow pattern distortion.
Dacron is also used in surgical bandages, extracorporeal devices, and prosthetic implants. Its moderate porosity and good mechanical strength make it a suitable material for these applications. Additionally, its physical, chemical, or biological properties can be modified to improve biocompatibility, antibacterial, anti-inflammatory, and endothelialization of blood vessels.

Its environmental implications
While Dacron, also known as polyethylene terephthalate (PET), is widely regarded as the first recyclable plastic, its environmental implications are complex. As a synthetic polyester fiber, Dacron is derived from petroleum-based resources, which has raised concerns about its environmental impact. However, efforts have been made to improve its sustainability, and it continues to shape the planet for the better.
One of the key advantages of Dacron is its durability. Its strength and resilience make it ideal for a range of applications, from clothing to household goods and even medical devices. Its moisture-wicking properties and resistance to stretching, wrinkles, and abrasion have contributed to its popularity. However, its environmental implications are more nuanced.
Dacron's production and use have had both positive and negative environmental impacts. On the one hand, the manufacturing of Dacron consumes a significant amount of energy, water, and chemicals, and it releases pollutants and greenhouse gases into the atmosphere. The use of petroleum-based resources and the challenges associated with recycling synthetic blends contribute to its environmental footprint. Less than 10% of all plastic is recycled, and if current trends continue, the amount of plastic in our oceans could surpass the number of fish by 2050.
On the other hand, Dacron has driven innovation in the recycling of plastics. Some manufacturers now produce Dacron from recycled PET bottles, reducing waste and lowering the carbon footprint associated with its production. Recycled polyester, while not the most sustainable fiber, has a significantly lower environmental impact than virgin polyester made from oil. It creates less waste, reduces carbon dioxide emissions, and consumes less energy and water. This shift towards recycled materials in the textile industry is a positive step towards mitigating the environmental impacts of Dacron and other synthetic fibers.
Additionally, Dacron's durability has environmental implications. Its resistance to water, UV rays, and mildew gives it a longer lifespan and reduces maintenance requirements, particularly for outdoor products. This extended durability can reduce the need for frequent replacements, potentially decreasing the overall environmental impact associated with the production and disposal of these items.
In conclusion, while Dacron's status as the first recyclable plastic is significant, its environmental implications are multifaceted. The use of petroleum-based resources and the challenges of recycling synthetic blends have negative consequences. However, the push for recycled polyester and the durability of Dacron products contribute to a more sustainable future. The ongoing development of Dacron and its sustainable applications will continue to shape the environmental impact of this pioneering recyclable plastic.
