Closing the Loop on a Complex Problem: The Textile Recycling Process for Polyester and Cotton Blends
The fashion industry has a waste problem, and it’s largely defined by a single, ubiquitous challenge: blended fabrics. The cozy, durable, and affordable polyester-cotton blend, which makes up a significant portion of the global textile market, is a prime example. While it offers the best of both worlds for consumers—the breathability of cotton and the wrinkle-resistance of polyester—it presents a formidable obstacle for recyclers. Traditional mechanical recycling, which shreds and re-spins fibers, simply can’t separate the two materials, leading to “downcycling” into lower-value products or, more often, a one-way ticket to a landfill.
However, a new wave of innovation is tackling this challenge head-on. The key to recycling polyester and cotton blends lies in advanced, sophisticated processes, primarily through chemical recycling.
The Challenge: A Tale of Two Fibers
The core difficulty in recycling a poly-cotton blend is the fundamental difference in the chemical properties of its two components:
- Cotton is
