Historical Context: The Origin Stories

Understanding the history of Tencel and polyester can provide a richer context to their current roles in the fashion industry.

Tencel (Lyocell):

Tencel, also known as Lyocell fabric, was developed in the 1980s as an environmentally friendly alternative to other synthetic fabrics. Its production process, which uses wood pulp from sustainable tree sources, was a groundbreaking approach to textile manufacturing. The Lenzing AG company owns the brand name Tencel and has manufactured lycoell for a long time. The first large-scale lyocell plant was opened by Lenzing in 1997.

Polyester:

Polyester, a synthetic fabric derived from petrochemicals, dates back to the 1940s. It was hailed as a wonder fabric due to its durability, wrinkle resistance, and affordability. Over the decades, its popularity soared, especially during the 1970s, when it became synonymous with disco fashion.

The main difference between the two fibers is that Tencel is made from wood, and polyester is made from petroleum.

Tencel (Lyocell): A Sustainable Marvel

Let’s start with Tencel, also known as Lyocell, a fabric gaining popularity for its impressive eco-credentials. Tencel is a semi-synthetic fabric from wood pulp, typically sourced from eucalyptus, beech, or spruce trees. The wood cellulose fibers are extracted from the trees. These Tencel fibers form the basis of Tencel fabric. 

Eucalyptus Trees and Sustainable Sourcing:

Eucalyptus trees are a primary source of wood pulp for Tencel production. They are known for their rapid growth, which makes them a sustainable and renewable resource. Tencel’s responsible sourcing of raw materials from these trees ensures minimal impact on forests.

The Closed-Loop Process:

One of the key aspects of Tencel’s sustainability is the closed-loop process used in its manufacturing. Unlike many other textiles, the closed loop process for Tencel minimizes waste and reduces the need for toxic chemicals. The process starts with wood pulped from trees, then dissolved in a chemical solvent (n-methylmorpholine n-oxide). This forms a thick solution that is then pushed through tiny holes to form individual thin fibers. They are then put in a water bath to remove the solvent, pressed and turned into fibers, and then fabric.

This manufacturing process of lyocell recycles nearly all solvents and water, making it a highly efficient and eco-friendly manufacturing process that minimizes harmful by-products. Tencel is referred to as a semi-synthetic fiber because of this process. Its main component is derived from natural materials that undergo a chemical process to create fibers.

Tencel’s Low Environmental Impact:

In terms of environmental impact, Tencel shines. It uses significantly less water than polyester, thanks to its closed-loop system. The production of Tencel also consumes less energy, resulting in a lower carbon footprint. These factors contribute to Tencel’s reputation as a sustainable fabric with a low environmental impact.

Polyester: The Synthetic Challenger

On the other side of the ring, we have polyester. This synthetic fabric has been a staple in the fashion industry for decades. Polyester is derived from petrochemicals, making it a purely artificial material. Specifically, it’s made from terephthalic acid and ethylene glycol (from crude oil) processed under high temperatures. It’s then turned into plastic pellets, fibers, and then fabric. It’s known for its durability and wrinkle resistance but comes with a significant environmental cost.

Synthetic Fibers and Their Impact:

Polyester is classified as a synthetic fiber, which means it’s entirely human-made through a chemical process. This process relies heavily on fossil fuels and energy-intensive manufacturing methods, contributing to a higher carbon footprint and more harmful by-products than natural or semi-synthetic fibers like Tencel.
