BROWNING TREATMENT is a powerful liquid treatment for removing jute stain cellulosic browning caused by overwetting or flooding of carpets and upholstery.
How Does It Work?
When a cellulosic fibre such as jute, cotton or linen is wet with water and allowed to dry very slowly, a brown discolouration often appears at the point where the evaporation of the moisture takes place. This brown colour is known as cellulosic browning. It results from the degradation of cellulose and is a similar discolouration to the yellowing that occurs as a newspaper yellows with age. Most carpets contain one or more cellulosic fibres. For example, in tufted carpets jute is used as the primary or secondary backing. Some rugs are made entirely of cotton. Consequently, when these carpets or rugs are cleaned by shampooing or by hot water extraction they may develop browning when they dry because the moisture may carry brown cellulosic matter up onto the fibres.
