Construction: Textures and Patterns
Today’s carpet offers much more than a conventional loop pile. To add to a room’s sophistication and interest, consider choosing a textured pattern.

New technology can produce multilevel loop and cut/loop patterns. Choose diamonds, bows, pin dots, or fleurs-de-lis designs that "pop out" in sculptured effects.

The texture, colors, and pattern of the carpet can be made to complement or contrast with patterns of your furniture and window treatments. Using a solid color, textured carpet is a great way to provide interest and
pizzazz, without going to a multicolor, overall pattern.

Textured styles also fit well with today’s active and casual lifestyles. Textured carpet can be created through the use of several construction techniques. Many of these styles are known for their soil-hiding ability.

Cut pile: Loops are cut, leaving individual yarn tufts. Still one of today's most popular constructions, its durability is achieved with factors including the type of fiber, density of tufts, and the amount of twist in the yarn.

Plush / Velvet -- Smooth, level surfaces; formal atmosphere, "velvet."

Saxony -- Smooth, level finish, but pile yarns have more twist so that the yarn ends are visible and create a less formal look. Minimizes foot prints.

Friezé -- In this cut pile, the yarns are extremely twisted, forming a "curly" textured surface. This informal look also minimizes foot prints and vacuum marks.

Level loop pile: Loops are the same height, creating an informal look. It generally lasts a long time in high-traffic areas. Many of today’s popular Berber styles are level loop styles with flecks of a darker color on a lighter
background.

Multi-level loop pile: Usually has two to three different loop heights to create pattern effects, providing good durability and a more casual look.

Cut and loop pile: Combination of cut and looped yarns. Provides variety of surface textures, including sculptured effects of squares, chevrons, swirls, etc.

Really Express Yourself!
Perhaps you are ready to boldly express yourself with a floral, fleur-de-lis, or multicolored carpet that will enhance plaids, stripes, or solids furnishings. European, English, French Country, and Colonial are some of the descriptive words used for the beautiful combinations of patterned carpet used with patterned furnishings.

Fibers
Fiber is carpet’s basic ingredient. The type of fiber used and the way the carpet is constructed determine how well the carpet will stand up to spills, pets, and daily traffic.

Approximately 97 percent of all carpet is
produced using synthetic fibers that are designed to feature style, easy maintenance, and outstanding value.

There are five basic types of carpet pile fibers.

Nylon: It is the most popular of the pile fibers. Wear-resistant, resilient, withstands the weight and movement of furniture, and provides brilliant color. Ability to conceal and resist soils and stains. Generally good for all
traffic areas. Solution-dyed nylon is colorfast because color is added in the fiber production.

Olefin (polypropylene): Strong, resists wear and permanent stains, and is easily cleaned. Notably colorfast because color is added during fiber production. Resists static electricity and is often used in both indoor
and outdoor installations because of its resistance to moisture and mildew. Used in synthetic turf for sports surfaces, and in the home for patios and game rooms. Many Berbers are made of olefin.

Polyester: Noted for luxurious, soft "hand" when used in thick, cut-pile textures. Has excellent color clarity and retention. Easily cleaned, and resistant to water-soluble stains.
Acrylic: Offers the appearance and feel of wool without the cost. Has low static level and is moisture and mildew-resistant. Commonly used in velvet and level-loop constructions, and often in bath and scatter rugs.

Wool: Noted for its luxury and performance, wool is soft, has high bulk, and is available in many colors.

Generally, wool is somewhat more expensive than synthetic fibers.

Blends: A wool/nylon blend combines the superior look and comfort of wool with the durability of nylon.

Acrylic/olefin and nylon/olefin are other popular blends, offering good characteristics of each fiber.

Quality Factors
The type of fiber used and the way the carpet is constructed etermines the basic performance of the carpet.
ghQuality can be enhanced by the way the fibers, or yarns, are twisted and heat set, and by the density of the
tufts. Deep pile height that’s densely tufted, has a luxurious feel; however, pile height is really a matter of
personal choice and does not, in itself, denote durability.

Performance Glossary
Density – refers to the amount of pile yarn in the carpet and the closeness of the tufts. The denser, the better.
Twist – the winding of the yarn around itself. A tighter twist provides enhanced durability.
Heat-setting – the process that sets the twist by heat or steam, enabling yarns to hold their twist over time.
Important in cut pile carpet. Most nylon, olefin and polyester cut pile carpets are heat-set.
Performance – Some manufacturers have a rating scale for choosing carpet for various traffic areas – high,
moderate or low.

BCF OR STAPLE?
When it comes to durability, there is little difference between bulked continuous filament (BCF) or staple (spun) fibers. The difference lies in the length of the fibers in the yarn, with staple having shorter lengths, giving the yarn more bulk (sometimes described as being more like wool).

When carpet is manufactured with staple fiber, there will be initial shedding of shorter fibers. It will soon stop,
depending on the amount of foot traffic and frequency of vacuuming. Wool is a naturally staple fiber; nylon
and polyester can be staple or continuous filament; and olefin (polypropylene) is usually BCF.
