Polyester is a durable, synthetic fabric that can be used for a number of things from sweaters to blankets, to trousers and jackets, and more. While polyester may feel good, if you have a polyester piece that sheds this definitely does not look good. Leaving behind unsightly lint balls and fibres is highly unattractive. While polyester shedding can be frustrating, treating it and preventing it can be done to help you avoid having to retire that polyester piece.
Brush down your polyester piece with a dog shedding brush or natural-bristled brush on both sides prior to washing. This will help to remove any loose fibres that could shed while washing or after the piece has been laundered.
Wash your polyester piece according to the temperature and washing instructions which came with it. Use a gentle detergent and pour one cup of vinegar into the wash with it. Vinegar will not only make your piece smell fresh, but will help deter shedding.
Hang polyester outside and let it dry. If it's raining you can dry it in your dryer, but plan to clean out the lint trap halfway through to remove any build-up.
Spray down your polyester liberally with some spray starch and wait two minutes for starch to dry. This will help to make the fibres of the polyester a little stiffer and less susceptible to shedding, without making the piece too stiff.
If the polyester continues to shed try brushing it daily or before you use it to remove as much of the loose fibres as possible. Also wash it once a week until the shedding lessens, then simply wash it as needed. If you are using the dryer to dry your polyester toss in a corduroy garment which will collect some of the loose fibres from the polyester piece as it dries.
