Excluding natural materials, nylon, polyester, and olefin are the mostly widely used fibers in carpet manufacturing, and each offers qualities useful in specific applications. Even though nylon is the most expensive type of fiber, it is also soft and resilient, which makes it great for any room in your home. Polyester is less durable than nylon, but quite cost efficient – offering a high level of resistance to stains, which makes it an ideal choice for areas such as dining rooms. Olefin is solution dyed, which results in a highly resistant stain carpet that can be cleaned easily without color loss. Unlike many other fibers, olefin is fade and mould resistant, which results in a carpet that works well both indoors or out. Often times carpet requires pads for added cushion that go under your carpet as well.
