Carpeting

Synthetic Fiber

90% of all carpet made today is synthetic

Nylon: 75% of all carpet made : Best for soil/stain resistance, maintaining color/styling, keeping its appearance, fade/heat resistance
Polypropylene: fade/stain resistant, moisture resistant, but not as resilient/resistant to abrasion as nylon. More limited color choices
Polyester: good stain/fade resistance, good color clarity and bulkiness

Natural Fiber

Wool: comes primarily from New Zealand, Argentina and UK; cleans well and ages beautifully but is most expensive and doesn’t stand up to abrasion or moisture as well as synthetics
