Viscose polyester yarn
Viscose works very differently to Polyester. Viscose is a semi-synthetic fibre made from a compound known as cellulose – a plant-based material. Like Polyester, it also comes in long smooth filament fibres, but that is where the similarities end.
Viscose: great for absorbing sweat
Unlike Polyester, Viscose is water absorbing; water is absorbed into tiny micropores in the fibres themselves. This makes Viscose highly breathable, which is crucial for comfort.
Breathable fabrics remove water vapour (and heat) from your skin, leaving you feeling cool, dry and comfortable. Because Viscose does this so well, it is ideal for clothing that is worn all day and for clothing that's worn next to your skin.
This is why we use Viscose fabrics for our undershirts. Normal amounts of sweating will be absorbed into the fabric and locked away, preventing sweat marks on your shirt. Water vapour is spirited away leaving you feeling cool and fresh. Not only that, but Viscose has been shown to inhibit those very same stinky microbes which Polyester encourages . No one really knows why, but the effect has been measured in several studies. Its lasting freshness only adds to its suitability for all-day wear – especially for those 12 hour days in the office.
But wait! It’s not all rosy for Viscose: it has its problems. Overwhelm Viscose with too much water (sweat) and it will become saturated and wet. Moreover, because it likes to absorb water, not repel it, it takes a long time to dry out. Excessive sweating into a Viscose top could leave you feeling cold and clammy for hours afterwards. This is one of the downsides of water absorbing Viscose.
