Olefin and polypropylene are two names for the second-most widely used carpet fiber after nylon. Olefin is not as durable as nylon but less expensive that is why most people prefer this.  Olefin is water resistant wicks up moisture.  It discourages mold and mildew build up.  It is great for outdoor carpets and damp basements.  It also dries very quickly when it gets wet.  The carpet is produced on a loom quite similar to woven fabric. The pile can be plush or Berber. Plush carpet is a cut pile and Berber carpet is a loop pile. It is specifically engineered to be tougher and more durable, provide almost a lifetime resistance to stains and abrasion, and resist wrinkles or abrasive wear damage. Polypropylene does have a tendency to shrink after being woven into a pattern or design..
