Small variations in color uniformity of handmade rugs. The dyes that are being applied to the rug are uneven. The uniformity of the rug can also be achieved by using wool from different dye lots (this effect may be done intentionally).

A chemical treatment added to carpet to reduce the growth of common bacteria, fungi, yeast, mold and mildew.

The fabric or yarns serving as a foundation for the face fiber.

A loop-pile carpet weave tufted with thick yarn, such as wool, nylon or olefin. Often having random specks of color in contrast to a base hue, this carpet style has a full, comfortable feel, while maintaining an informal, casual look. Currently, this term has expanded to describe many level or multilevel loop carpet styles.

A band or strip sewn over the carpet edge to protect, strengthen or decorate the edge.

Term used to describe color loss to the carpet. For light color carpets, the color appears whiter and brighter, whereas for darker color carpets, the color can be a lighter shade of the original color or a different color entirely (i.e. bleaching on a blue carpet can turn the carpet peach).

This is a loss or transfer of color from one section of the carpet to another.

Brown carpet discoloration caused by over-wetting by either a carpet cleaning product or with water alone. It is the saturation of the carpet that may allow moisture to reach the carpet backing or even the padding.

Visible continuation of the warp threads at both ends of the carpet. The fringes are formed by knotting the bundles of warp strings from both ends of the rug after the rug has been cut from the loom.

Natural fiber that is often used for rug or carpet backing material.

The pileless web of warps and wefts between the rug's pile and the knotted fringe. This is also the name for a rug without pile.

Strands of wool yarn looped around two adjacent warp threads and then cut to form the pile or nap of the rug (surface of carpet). There are two basic types of knots used in oriental rugs.  Persian Senneh is a fine asymmetrical knot used in fine urban and complex tribal carpets. These rugs have a light and a dark side.  Turkish Ghiordes have a symmetrical knot used in most tribal rugs, and it makes for a higher pile heavy wearing style. Chinese carved carpets also feature this knot.

Manufacturers’ definitions of matting may vary. Matting is usually the result of the untwisting of the yarn and the intermingling of the yarn tips through foot traffic. Matting may be caused by various factors, including an improperly specified cushion, cushion failure, or improper maintenance. Matting is not considered a manufacturing defect unless it is specifically cited in the manufacturer’s warranty.

Fungus growth that can occur on carpet fibers and causes odor and fiber degradation.

The visible surface of carpet consisting of yarn tufts in loop and/or cut configuration; sometimes called “face” or “nap”.

Pile Crush:
Loss of pile thickness due to compression and bending of tufts caused by traffic and heavy furniture. The tufts collapse into the air space between them. This may be irreversible if the yarn has inadequate resilience or the pile has insufficient density for the traffic load.

A condition of the carpet face (which may occur from heavy traffic) in which fibers from different tufts become entangled with one another, forming tangled masses of fibers.  Pills may be cut off with scissors.

A simple wrapping of dyed yarn along the entire length of both sides of the rug.

A change in the appearance of a carpet due to localized distortions in the orientation of the fibers, tufts or loops.  Shading is not a change in color or hue, but a difference in light reflection.

A natural plant fiber used in mimicking the woven look of rugs.  The pattern has the appearance of interwoven webs but is created on a tufting machine by continually adjusting the height of each pile yarn.

Protrusion of individual tuft or yarn ends above the pile surface.  It may be clipped with scissors but should not be pulled out.

Stain-resistant carpet:
Almost all carpet manufactured today has finishes that make it more stain- and soil-resistant, but no carpet is entirely stain proof.

Synthetic Fibers:
Most carpet fibers used today, in contrast to animal or vegetable fibers.

Topical treatment:
Includes soil retardant, stain repellent, antistatic treatment and deodorizer.  The use of after-market, topical treatments without the express approval of the carpet manufacturer prior to application may void applicable warranties.

The carpet cushion under rugs.

Most carpet manufacturers offer “wear” warranties of various time lengths. According to these warranties, “wear” is defined as the loss of pile weight or pile fiber (usually 10 percent) due to abrasive loss of fiber by weight.  What appears to be wear, or pile fiber loss, may actually be matting, crushing or permanent fiber damage caused by soiling rather than loss of fiber.  There is seldom actual loss of pile fiber.

When the residual stain underneath the carpet resurfaces to the top.

Carpet discoloration caused by either the stain itself or over wetting.
