Modal polyester, often simply called modal, is a semi-synthetic fabric prized for its softness, drape, and resistance to shrinkage. It’s a type of rayon, which means it’s made from cellulose fibers derived from wood, typically beech trees. However, the manufacturing process and resulting properties distinguish modal from other rayons like viscose. While technically a modified cellulose fiber, its characteristics sometimes lead to it being mistakenly referred to as a type of polyester, hence the name “modal polyester.” Let’s delve into the composition, production, properties, uses, and environmental impact of this increasingly popular textile.
The Composition and Production of Modal
Modal is derived from cellulose, the primary structural component of plant cell walls. Beech trees are a common source of cellulose for modal production due to their sustainable growth and regenerative properties. The process involves several steps:
First, the wood pulp is harvested and broken down into a slurry. This slurry undergoes a chemical treatment to extract the cellulose. Unlike viscose, modal production uses a more environmentally friendly solvent recovery system.
The extracted cellulose is then dissolved in a solvent and forced through spinnerets, tiny holes that create continuous filaments. These filaments are then stretched to align the cellulose molecules, which contributes to the fabric’s strength.
Finally, the filaments are treated chemically, washed, and spun into yarn. This yarn can then be woven or knitted into fabric. The entire production process is carefully controlled to ensure the desired properties of the final modal fabric.
Differentiating Modal from Viscose and Lyocell
Modal, viscose, and lyocell are all rayon fabrics derived from cellulose. However, significant differences in their production methods and resulting properties exist.
Viscose is the oldest and most common type of rayon. It’s known for its affordability and versatility. However, the production of viscose often involves harsh chemicals and has a less efficient solvent recovery system than modal production, raising environmental concerns.
Lyocell is another type of rayon that is considered more sustainable than both viscose and modal. It utilizes a closed-loop production process, meaning that the solvents used are almost entirely recovered and reused, minimizing waste and environmental impact. Lyocell is also known for its strength and moisture-wicking properties.
Modal falls somewhere in between viscose and lyocell in terms of environmental impact. It generally uses less harsh chemicals than viscose and has a better solvent recovery system. However, lyocell is generally considered the most sustainable option.
The key difference lies in the structure and treatment of the cellulose fibers. Modal fibers are stretched more than viscose fibers, resulting in a stronger and more stable fabric. This also contributes to modal’s resistance to shrinkage.
