Every IPL season, millions of fans cheer for players wrapped in one of the most toxic materials in modern textiles. Nobody’s talking about it. It’s time someone did.
What’s Really Touching the Skin
When Rohit Sharma sweats through a chase or Virat Kohli dives at cover, the fabric against their skin is 100% polyester — a petroleum-derived plastic. It is lightweight, moisture-wicking, and looks brilliant under stadium lights. It is also a slow-release chemical delivery system pressed against a sweating athlete’s body for hours every day.
Polyester picks up a cocktail of additives during manufacturing: antimony trioxide (a probable carcinogen used as a production catalyst), formaldehyde (a confirmed carcinogen for wrinkle resistance), PFAS — so-called “forever chemicals” added for stain resistance — and phthalates, which are endocrine disruptors that interfere with hormone function. These chemicals do not vanish post-production. They stay in the fabric.
This is where athletes face a distinct danger. When the body heats up and sweats, skin pores open. Sweat accelerates chemical migration from fabric to skin. An IPL player training in 40°C heat, wearing polyester for six to eight hours daily, is passively absorbing a chemical load under conditions that maximise skin absorption. Research links PFAS to fertility disruption and immune dysfunction; phthalates to reduced testosterone production; and formaldehyde to leukemia and skin cancers.
The Planet Gets It Worse
Every polyester wash releases microplastic fibres too small for any sewage treatment plant to filter. These flow directly into rivers and oceans. A single wash cycle can release up to 700,000 microplastic fibres. The UN Environment Programme confirms synthetic textiles account for 35% of all microplastics in our oceans. Scientists estimated 51 trillion microplastic particles in the world’s oceans as of 2024.
These particles are ingested by marine life, disrupting reproduction and re-entering the human food chain through seafood. Microplastics have now been detected in human blood, lungs, placentas, and brain tissue.
Polyester does not biodegrade. It fragments into smaller pieces across 200 to 500 years. Every IPL jersey ever produced still exists on this planet in some form.
The Recycled Polyester Lie
Chennai Super Kings announced their 2025 jersey includes 15% recycled polyester, marketed as an environmental commitment. The data says otherwise.
A study by the Changing Markets Foundation, conducted by the Microplastic Research Group at Çukurova University — testing 51 garments from Adidas, Nike, H&M, and others — found that recycled polyester releases 55% more microplastic particles per wash than virgin polyester. The shed particles are also 20% smaller, making them more dangerous. Smaller particles disperse faster, penetrate biological barriers more easily, and are more readily ingested by organisms.
Why? Mechanical recycling shortens polymer chains, making the fibre weaker and more brittle. It degrades faster and sheds more, sooner. A Greenpeace review confirmed recycled plastics contain higher concentrations of toxic chemicals than virgin plastics, due to contamination accumulated during the recycling process itself. CSK’s 15% recycled polyester jerseys are, by the evidence, more harmful per wash than a 100% virgin polyester jersey. The sustainability claim is factually false.
The Blend Problem That Makes Recycling Nearly Impossible
The deeper failure: what happens when consumers try to recycle blended garments — polyester-cotton mixes, which dominate the global market.
Separating polyester from cotton requires advanced chemical processes: hydrothermal treatment, switchable solvent systems, or supercritical fluid decomposition. Research published in ACS Omega confirms mechanical recycling is only feasible for single-material waste. Blended fabrics require chemical recycling — expensive, energy-intensive, and not commercially viable at scale anywhere in the world today.
The technology to affordably separate cotton from polyester at mass-market scale does not exist in practice. Most polyester-cotton sportswear sent for recycling ends up incinerated, landfilled, or downcycled into insulation and industrial rags — not back into textile fibre. The circular economy story brands tell is built on a process that does not function for most of the clothing people actually wear.
The Inconvenient Conclusion
IPL players are national icons. The jerseys are cultural symbols. And every one is made from a non-biodegradable petroleum product that leaches carcinogens onto athletes, sheds plastic into oceans, and gets worse when brands greenwash it with recycled variants.
Sustainable alternatives exist — bamboo fabric, organic cotton performance blends, merino wool — offering comparable athletic performance without the chemical payload, microplastic shedding, or centuries of environmental persistence. The industry has not shifted because polyester is cheap. That is the only honest reason.
The next time an IPL franchise announces an eco-friendly jersey made from recycled polyester, ask one question: which independent laboratory tested its microplastic shedding rate? The silence will tell you everything.
If you are waiting for a country, a league, or a governing body somewhere in the world to lead the way on natural fiber sportswear — stop waiting. Not one exists.
Every professional sport on the planet, from the All Blacks of New Zealand to every FIFA national team to every IPL franchise, wears polyester on competition day.
New Zealand is home to Icebreaker, the world’s most respected merino wool performance brand — and the All Blacks still wear Adidas polyester on the field.
The only places where natural fibers survive in competitive sport are traditional forms that predate the invention of plastic: Bhutan’s national sport of archery, where players compete in the hand-woven Gho by cultural mandate; Sumo wrestling in Japan, where the mawashi is silk or cotton by centuries of tradition; and India’s own kushti and village-level kabaddi, where cotton still touches skin.
The moment sport became a commercial product with Adidas and Nike sponsorship contracts, the athlete lost the right to choose what fabric they wear.
Until textile governing bodies, sports federations, and broadcasters treat microplastic pollution and athlete chemical exposure as the public health crisis they are — not as a marketing footnote — the jersey will remain plastic, the oceans will keep filling, and the players will keep absorbing what no one is talking about.
