Although, we often use the word microfibre as a generalised term for a whole towel or cloth it actually refers to each fibre in the material. In order to be a microfibre, by definition, the single fibres have to be finer than 1 denier, which roughly equates to a single strand of silk. The premium cloths we develop have microfibres between 0.1 and 0.3 denier, which is up to 200 times finer than a human hair. Microfibre cloths are made from a synthetic blend of polyester - which makes up most of the structure - and polyamide (Nylon) used for increased absorption and density. These single fibres are also split to make them extremely fine during the manufacturing process and then woven into various constructions that have different attributes that are ideal for specific tasks. A split microfibre strand has a cross section much like an asterix (*), this not only means it has a hugely increased surface area, but that it can lift away fine particles within the strand itself. So, when these fibres are run across any wet or dry surface, they will pick up the fine particles or water molecules and hold them within the single fibres. This is why a microfibre will grab dust, grime and water, rather than simply move it around.
