Polypropylene is the most widely used fiber in machine-woven rugs. Polypropylene’s strength lies in the fact that it can take many forms and used to make different types of rugs ranging from the lush soft shaggy to the budget anti-slip flat-woven kitchen rugs. In addition, polypropylene rugs can be safely treated in many ways to achieve certain properties; these include the creation of rugs that are anti-static, anti-bacterial, dirt-repellent, and colourfast. Furthermore, polypropylene rugs always win in terms of value as the fibres are cheap to produce and they are almost always machine made.
