A bulky, knobby-looking loop pile with much larger loops than commercial grade loop pile carpet, usually made of olefin or olefin/nylon blend. Berber often has random specks of color, which are usually nylon-blended with the base olefin fibers. Berber is very popular residentially because of its informal look, especially in family rooms, recreation rooms and multimedia rooms.


A carpet or rug in which a raised pattern or engraved effect is formed by using heavy twisted yarn tufts on a group of straight fibers.

Cut-loop pile:

Carpet with a face that shows a pattern made up of a combination of loop pile tufts and cut pile tufts to give a sculptured design.

Cut Pile:

A carpet pile, the face of which is composed of cut ends of pile yarn. Clean with the pile direction if floor tool pops or “chatters”.


(Pronounced “free-zay”): A tightly twisted yarn that gives a kinked or curled appearance to carpet pile. Pile lifting is too aggressive for this style of carpet.

Fusion bonded:

Backing material for fusion bonded cut-pile carpet is a system of layered vinyl or plastic compound and fiberglass scrim for dimensional stability. Usually used in fabrication of 6-foot wide carpet or modular tile.

Level loop:

Loop pile where the loops all have the same length and, therefore, give a smooth level surface. Larger loops would be the Berber style. The larger the loops, the greater possibility for crushing.

Loop Pile:

Pile surface in which looped yarns are left uncut. Can be level, textured or patterned. Also called “round wire” in woven carpet terminology.

Modular carpet:

Also called carpet tile. Generally 18″ x 18″ squares.

Multi-level loop:

A loop pile construction in which some loops are smaller than others, resulting in a sculptured appearance. Rough surface. Clean at 45-degree angle, or you’ll get splotching and streaking and lines from the floor tool “chattering."


Sometimes called velvet plush or simply velvet. A luxurious, smooth-textured, highly finished, sheared level-cut pile carpet surface with a smooth, formal look in which individual tufts are only minimally visible. Its low twist and the overall visual effect is that of a single level of yarn ends. Plush is longer and more dense than a “Saxony”.


Textured pattern created by shearing some of the top or higher loops and leaving others looped. This gives a cut/uncut texture.


A dense, smooth, level-cut pile carpet with surface yarns that are closely packed and even across the face with the yarn ends visible to create a less formal look. Minimizes footprints.


A cut- and loop-patterned carpet where all of the high pile is cut and the low pile remains a loop.


A deep-pile texture with long-cut surface yarns. Pile height is greater than 3/4 inch, with density not exceeding 1800. Shag is nearly impossible to clean satisfactorily.


Strictly speaking, sisal is a tough plant fiber from the West Indian Agave plant and is used sometimes to make rope. Now it is applied more loosely to a particular woven carpet or rug style normally of natural fibers, such as sisal, jute, hemp, wool, sea grass, etc. Natural Sisal water spots severely, has very poor clean ability and is often dry clean only because it readily browns. Additionally, the pattern usually results in poor vacuuming. If wet cleaning, always apply Brown Out® afterward and protect with fluoro chemical protector such as 3M Scotchgard™, Brand Carpet and Upholstery Protector or Teflon® Advanced Carpet Protector. The preferred detergent to use when wet cleaning sisal is Natural Fiber Cleaner.


Curled or twisted tufts make for a textured surface that helps mask footprints. This style is also frequently called trackless. The major difference between a plush or velvet carpet and a textured carpet is the appearance of the color. A plush will have a very uniform color. A textured carpet (even if it is the same color as the velvet) will look like it has a random mix of light and dark fibers. This is because the fibers in a textured carpet are twisted to hide footprints.
