Carpet Fibers
Nylon: This is the most popular
synthetic carpet fiber used today. It offers tremendous value,
performance, and ease of maintenance. Nylon provides brilliant colors
and hides soil and traffic well. Nylon, however, fades in the direct
sunlight so if the floor is going to be exposed to harsh sun, a
solution-dyed nylon product with colorfast performance is a perfect
alternative.
Olefin: This fiber is also
called polypropylene, and is extremely popular in Berbers and level
loops. Olefin carpets are highly stain, static, mold, and mildew
resistant. They can be used for indoor or outdoor carpets, including
outdoor turf. Their resistance to mating and crushing are not as good
as a nylon fiber. Olefin is extremely colorfast and will withstand
strong chemicals that use up to 50% bleach.
Polyester: Gives excellent
color clarity with a soft feel to the carpet. Polyester is more
colorfast than standard nylons, though not as tough or durable.
Acrylic: Has a real wool look
and appearance. Used mainly in level loops, bath mats, and some velvet
carpet styles. Offers good mold and mildew resistance with low static
levels.
Wool: Wool has been used for
floor covering for as long as rugs have been hand woven. It is the
fiber by which all other fibers are judged, and is the fiber of choice
for discerning customers. Worldwide, wool is less than 15% of total
carpet volume. Virtually all handmade area rugs, most woven carpets, as
well as the majority of patterned carpets for quality homes or heavy
contract use wool fiber.
CARPET BUYING TIPS
Many homeowners choose carpeting because it is warm, and soft under
foot. When you select a carpet you generally buy it with the
expectations that your new carpet will look just like the sample in the
store for many years. Having some general knowledge about the different
characteristics of carpeting will help you choose the best carpet to
meet your expectations.
Below are a few things to help you understand why certain carpets perform better than others.
YARN TWIST: When it comes to
carpet "tighter is better". In general terms, the tighter the twist the
longer the carpet will perform before it begins to crush and mat. By
taking lots of fine fiber strands (called filaments) and spinning them
into a tightly twisted yarn and then locking them all together with
heat you get a much more resilient yarn for making carpet.
SHORTER NAP: The height of the
carpet's nap is also important to the overall performance of the
carpet. The higher the yarn stands above the backing of the carpet the
more difficult it is for the manufacturer to make the carpet crush and
mat resistant. So the shorter the pile height the more crush resistant
and the longer the like-new appearance of your carpet will last.
STITCHES PER INCH: Like most
fabric materials, carpet that has more yarn (or stitches) per inch will
also be more crush and mat resistant. Some carpets are so dense that it
is nearly impossible to push your fingers in between the yarns.
Obviously, the carpets where the yarns are so crowded and packed
together will have an easier time resisting crushing.
CARPET CUSHION: A good quality
carpet cushion will extend the life of any carpet, regardless of the
quality of the carpet. Carpet cushion serves a vital purpose which is
often overlooked. Good quality carpet cushion acts as both a shock
absorber and a spring which helps improve a carpet's overall
performance. Review the carpet manufacturer's cushion recommendations
prior to purchasing a carpet.
CONTINUOUS FILAMENT NYLON (CFN): If
you see on the back of a carpet sample a label that says "CFN", or
"BCF", that means this carpet is made from continuous filament nylon.
Continuous filament nylon starts out as one long continuous strand
before made into yarn. The other type is called staple nylon, which
means each fine filament starts out as a short strand about 8 inches
long before it is spun into yarn and then tufted into carpet. Both BCF
and Staple yarns are used to tuft carpets. BCF stands for "bulked
continuous filament" yarn. This yarn is comprised of a given number of
filaments or continuous strands of nylon that have been extruded and
pulled together into yarn bundles. These bundles are then texturized
into a kinked or curled configuration to increase bulk and cover. At
this point, if desired, the BCF yarn may be heat-set to lock in the
twist before being tufted into carpet.
Staple refers to a fiber in the natural unprocessed state that has not
yet been turned into yarn. Bales of Staple fibers, each about 8 inches
long, are shipped to the carpet mills, where they are processed into
spun yarns. At this point, if desired, the Staple yarn may be heat-set
to lock in the twist before being tufted into carpet.
Shedding is probably the biggest difference cited between carpets made
with Staple and BCF. Shedding is a normal characteristic of most new
carpeting.
There are two types of shedding. Many carpets are sheared as one of the
final steps in the manufacturing process. Although large vacuums are
employed to remove these loose fibers, some of the cut fibers will fall
into the carpet pile, causing minor shedding when the carpet is first
installed.
Because of the essential and unique characteristic of any spun yarn,
carpets made with wool or man-made Staple fibers will not have all the
fibers anchored into the carpet backing. A small percentage of these
fibers will be removed by vacuuming during the first few months after
the carpet is installed. The length of time the carpet will shed
depends on the pile height and type and frequency of vacuuming. This
normal loss of fiber will not affect the durability and performance of
the carpet, as the amount of fibers removed is very small compared to
the total amount of fibers in the carpet.
LOOPED CARPETS: From level
loops to berbers there is an important factor to look for when buying a
crush resistant looped carpet. This is the density of the loop and how
much free space is in the middle of the loop. The more filaments that
are packed in the yarn and the tighter the loop the better the
performance will be.
