The use of hydrogen peroxide in the final rinse of the scour before drying improves the colour of the scoured wool but this practice can lead to unnecessary fibre damage if further oxidative processes such as shrink-resist treatment or bleaching are performed in Cited by: For example, if the sample weight equals g and the combined dry sub-samples weights equals g then: Moisture Content = (Original Weight – Oven Dry weight) x Original Weight = ( – ) x = % b) Regain This indicates the amount of moisture that the oven dry wool has regained at the.
While wool scouring in simple terms is the washing and drying of wool, in reality there are a considerable number of other operations involved – opening, blending, mechanical cleaning, baling, sampling and testing.
