Nylon carpet fiber is the most popular fiber (about 90% of residential carpets and 65% of all carpets). Nylon carpet fiber is a good choice for all traffic areas because it is durable and static free, maintains fiber height, and resists soiling, staining, and mildew. Nylon fibers, which are dyed after production, maintain color. Some nylon carpet fades with sunlight. It comes in continuous or spun fibers. Spun yarn is made of short lengths of fibers that are spun together. Thus, continuous filaments are less likely to unravel.
- Yarn-forming substance of any long-chain, synthetic polyamide having recurring amide groups as an integral part of the polymer chain
- Offered as BCF or staple, both used for commercial application
- Sold as a solution-dyed yarn
- Accounts for 65% of all face fibers in carpet products
- Good bulk and cover
- Good crush resistance
- Long wearing
- Clear colors
- Range of dye depths
- Excellent luster range
- Good performance, even at low weights
- Good soil resistance
- Responds we to cleaning
- Higher cost
- Easiest of synthetic fibers to stain with typical food and beverage spills (fabric protection helps fight this problem)
- Will lose color in presence of bleach, especially chlorine
Practically any style carpet, in any price range, can be made with Nylon and easily dyed and finished by any method.
Acrylic Carpet Fiber
Acrylic carpet fiber offers the appearance and feel of wool without the cost. Acrylic carpet fiber has a low static level and is moisture and mildew resistant. It is commonly used in Velvet and Level Loop constructions; it is often used for bath and scatter rugs.
Acrylic carpet fiber is known as art, art wool, or man-made wool because it is an artificial fiber. These fibers provide the look and feel of wool at a fraction of the cost. Acrylic carpet fiber resists static electricity, moisture, mildew, fading, crushing, staining, and sun damage. However, acrylic fiber is not durable enough for high traffic areas (it fails under abrasion when compared to other fibers).
