Knitted fabric originally made by the fishermen of the English island of the same name: interlacing of a single thread horizontally and vertically to make a single jersey. Its typical elasticity makes it suitable for different uses such as menswear and womenswear, underwear, technical sports and industrial clothes. according to its structure and use for which it is intended, the main processes, in addition to dyeing, are finishing and some important pre- dyeing treatments. The most common are mercerizing and singeing. Sanforizing is the most important final operation, which is also required after grinding in order to give Jersey items dimensional stability, uniform appearance and hand. It works with compactors equipped with rubber belt (Sanfor) for items in Viscose, Cotton and blends. This treatment ennobles the material, giving a silky hand, smooth surface and reducing the washing.
