It's no secret that in the warmer months we all prefer wearing clothing made from natural fabrics and fibres, as they seems to keep us cooler. Ever wondered exactly why though? Read on to discover why cotton is much cooler to wear than artificial fabrics like polyester.
Due to its structure, cotton moves air very well.
Cotton fibres (below) are flat and twist like a ribbon. As a cross section they form little kidney shaped structures which trap and hold air in the spaces between them. This gives cotton it's breathability, and keeps you cooler by circulating air within the fabric itself.
As a comparison, artificial polyester fibres (below) are round and smooth, and stack together closely, inhibiting any air spaces to form between them. This means polyester has no breathability and feels much warmer when worn.
The air spaces within cotton and other natural fibres such as linen allows heat to move away from your body, thereby keeping the body cooler in comparison to polyester or rayon.
Cotton is also hydrophilic, which means that water sticks to the fibres. This is due to the fact that natural fibres are rough and coarser than artificial fibres, and allows the fabric to 'wick' water away from the body to provide an evaporative cooling effect.
This is one of the reasons why we love natural fibres, and cotton in particular so much!
