Polypropylene is made from petroleum based products, it is inherently stain resistant to most stains and can withstand very harsh chemicals, even chlorine bleach.
Due to the nature of the fibre, certain oil based chemicals (including the oils from your skin ) can fix itself to the fibre and cannot be removed. On light colours this will be seen as soiling in the traffic areas, spots reappearing after cleaning and yellowing.
Due to the fibres low melting point, abrasive wear and friction on the pile surface can cause irreversable flattening and matting. This is less obvious on mid tones and darker colours. Although resistant to fading, intense sunlight can degrade the surface of the pile. As with all fibres there are varying qualities of polypropylene and they can perform quite differently in the same location, the fibre can be chemically set or heatset, which has an impact on the look, handle, performance and price of the finished carpet.
Given all the above Polyprop in various forms is still sold widely, it does not shed fibres, is easy to clean and relatively inexpensive in comparison to the better quality polyamides and wool fibres. Certainly the better quality polypropylene fibres represent excellent value for money and there is wide selection of colours and styles to choose from.
