First report on wool and shrinkage

06. May 2010 Effect of spinning speed on wool shrinkage in wash is the first report published in the Valuing Norwegian Wool project. The project was launched March 1st this year, and so far there have been some results in the area of centrifugal revolutions of laundry machines. Studies do show that one can increase the spinning speed up to 1400 revolutions without the wool garments shrinking. This results in shorter drying-time and thereby easier care.

The next lab studies will look at how washing wool separately as opposed to mixing fibres influences wash-results, since filling up washing machines saves both time and energy. But the current report shows that there is little difference in spinning wool in washing machines, whether one choses 400, 900 or 1400 cycles. This is because the wool actually lays still on the bottom, the garments do not themselves get centrifuged. Similar findings have been duplicated at the Technical University of Istanbul, Faculty of Textile Technologies and Design; but with a wool-blend.
