Drying involves the removal of relatively small amounts of water remain in the fabric after squeezing or hydro-extraction. The amount of water remains in a fabric depends of the thickness of the fabric and also the chemical interaction between the water molecules and the surface of that fabric. If the fabric is hydrophilic, then during wetting of the fabric it will absorb more water and also will retain more water during hydro-extraction than a hydrophobic fabric. In the process of drying, heat is necessary to evaporate water or moisture from the fibre in a fabric and a flow of air is needed to carry away the evaporated water/moisture.
