Washing:

Garments made from polyester should be washed separately from other garments.

Garments should be washed frequently to avoid the setting of any staining.

Classify the garments by the level of soiling.

Use a maximum wash temperature of 60°C; garment size change is likely to occur at higher temperatures.

The cool-down rate from the main wash should be about 2-3°C per minute.

Polyester fabrics can be susceptible to attract foreign textile fibers and soap residues, which is evident as white spots on the fabric surface, if the washing machine is overloaded and the liquid ratio is too low.

It is recommended to have a sufficient rinsing process, when using bleaching and disinfection chemicals in the washing process, to avoid corrosion on metal trims e.g., buttons and zippers.

The garments need only a short hydro extraction as they do not hold a lot of water and to avoid creases. The extraction should be set to allow 40-45% water by weight to be left in the garments for optimal

appearance after drying.

Drying:

Tumble-drying should be as short as possible and done at low temperature (one dot) so that the garments are not over-dried, which can damage the fabric. Tumble drying should also include a cool-down period to avoid creases.

If the garments are tunnel-finished, they should be fed into the tunnel finisher separately from other blends and finishes so that efficient drying and finishing takes place.

A fabric surface temperature of 120-130°C is recommended for good appearance. Bone-dry garments (garments where no water is left after washing) must not be tunnel-finished as this can cause problems such as shrinkage and scorching (change of surface color and texture due to heat).
