Carpet Color Loss

Carpet Color Loss – Fading and Yellowing

Terms such as yellowing are often unclear. “Yellowing” may not mean yellow in color. Yellow complaints often range in color from gray to yellow to green. The frequency of these complaints is greater on lighter and pastel colors. Commonly carpet color loss problems are seen on white, light gray and light blue residential style carpets. White carpet is not common on commercial installations; therefore, on commercial installation we see the most problems with grays and blues.

Carpet Color Loss May Be Shading

Much of the time when a carpet is inspected the reported carpet color loss will be readily identifiable as shading, soiling or abrasion. Abraded fibers are usually a more of a gray or brown discoloration but will often appear as a yellow discoloration depending on the color of the carpet.

Understanding Color Change Differences

With many different problems often referred to as the same, you may wonder where start. Actually, it is not as difficult as it seems if you come at it from the right direction. Here are a few tips that may help you to pin down the problem:

Identifying a Concern

Check for shadows. Is there less or no difference when window coverings closed?
Check the carpet with a high intensity lamp such as a shop lamp. Do you see more spots than were originally visible? Are the areas in spots, stripes, follow a pattern, or in another shape all together?
Is the problem only in the traffic lanes? If so this is likely a soiling condition.
What does it look like under ultraviolet light? Does it look a brighter yellow, glow blue, green or some other color or is there no change in the carpet’s appearance between the discolored area and the rest of the carpet. If it glows blue or blue-white, consider Optical Brightener. If the area glows yellow or yellow-green, consider urine. Point of note is that you will sometimes find Optical Brightener discoloration and urine in the same locations as the consumer has performed routine spot cleaning there.

A Few Additional Steps in Identifying Concern

Does the area appear as a color loss?
Is the discoloration only under furniture or rugs or is it symmetrical as if it has been under furniture or rugs it may be formaldehyde yellowing.
Is the yellowing only in darker areas and not above seaming tape or tackless strip? If so, consider BHT yellowing. BHT yellowing from cushion is always a big concern. While most residential carpet installations will be over cushion, many commercial installations will be direct-glue-down and cushion will not be a factor.
If the discoloration is near windows and sliding doors consider sun fading.
If the discoloration is overall but looks like fading, you may want to consider gas fading.
The discoloration is predominant around walls, consider flea and bug sprays.
The carpet is kind of brown on the tips, the problem showed up after cleaning and the carpet has a jute back, or the pile yarn is cotton or wool, cellulosic browning may be the culprit.
The discoloration is around a bathroom vanity or other area where you see aerosol products.
Is the discoloration near a vinyl floor or other areas where waxes and other floor care products are used? (Wipe the area with a clean towel and see what type of residue you attract).
Is the pH of the yellowed area highly alkaline?

Shift Marks in Carpet

By Terry Weinheimer 14 Comments

Shift marks are one of the most controversial claims in the carpet industry. Carpet manufacturers will tell you that shift marks are a normal characteristic and not a defect. Others in the industry often disagree. So what are shift marks and are they a defect or not?

What are Shift Marks?

Carpet Shift Marks — Shift marks viewing the carpet side-to-side

Shift marks are more commonly seen as narrow lines or bands that repeat across the width of the carpet at regular intervals. The surface of the carpet may have narrow widthwise gaps in the pile. The actual gaps can sometimes be difficult to see. Shift marks are most common with graphics or stepover stitch loop-pile carpet. Shift marks can also occur with cut pile carpet.

Shift marks are created

shift marks showing on carpet back — Shift marks showing on primary back of carpet

Tufted carpet is manufactured using a tufting machine with a needle bar that can hold up to 1,800 or more needles. A tufting machine that has been set to manufacturer 12 foot wide 1/10 gauge carpet holds 1,440 needles across its width.With step-over stitch the needle bar shifts in a side-to-side direction. The needles stitch the yarn through the primary backing material. As the needle bar is shifting, tension is placed on the yarn as it is being pulled down.

Shift marks are caused by the yarn being starved or pulled down as the needle bar is shifting back and forth. This added tension results in the appearance of bands or short, little row lines that appear on the face of the carpet. These bands are the most noticeable where they line up at a seam and often start appearing more after the carpet has been down for a while. Shift marks are not correctable.

Are Shift Marks a Manufacturing Defect

No: With commercial looped carpet that is manufactured using a shifting needlebar, it is a sometimes an unwanted characteristic that is not correctable.

Yes/Maybe: With residential cut pile carpet. If the shift marks are not seen in a large sample of the carpet that the consumer ordered from, they did not receive the appearance they bargained for. This is a visual defect though the manufacturer may see it otherwise. It does become the dealer/installer responsibility not to install carpet with visual defects. While shift marks do affect the appearance of a carpet they do not affect its performance.

Carpet Warranty Limitations Residential Carpet

There is a variety of Carpet Warranty Limitations in nearly every carpet warranty. Some of these restrictions are weasel-like (escape) clauses though most are sensible. Sensible or not, a wise consumer should review and understand them prior to making their purchase.

Carpet Warranty Standard Limitations

Following is a list of Standard Warranty limitations:

Common Limitations and Exclusions

Rental units: Often excluded.
Damage from abnormal use such as water damage, plumbing, storm or flood, damage from smoke or fire, damage from improper cleaning methods or materials, and from improper maintenance.
Carpet appearance not covered unless specifically listed in the warranty. Appearance includes, not limited to changes from wear, matting, crushing, shading, loss of texture, tears, pulls, cuts, pilling, shedding, fuzzing, pets, burns, furniture indentations, improper installation, defective carpet manufacture, improper cleaning materials or methods.

Common Warranty Coverage and Requirements

Repairs or replacements limited to the affected area of the carpet.
Required replacement limited to the affected area of the carpet, which will mean the room where the defect or problem exists and only extending to a point such as the nearest wall, doorway or entrance. If identical carpet not available, replacement limited to carpet of comparable cost, quality and sometimes color.
The fiber or carpet manufacturer will only pay for the carpet. Some will pay for the removal of the old carpet and installation of the new carpet. Generally excluded on a replacement are moving or replacing equipment, furnishings, partitions, etc.
To qualify for repair or replacement, consumer may be asked to provide the original sales receipt or other documentation showing proof of purchase and installation dates. This information must be acceptable to the manufacturer.
Some warranties are not transferable. Some warranties are transferable only in owner-occupied residences.
Many warranties prorated over a specific period of time with only the carpet covered. The installation, pad and maintenance cost excluded.

Commercial Warranties will cover similar carpet warranty limitations to those of residential warranties and should be studied carefully by all involved.

No Mat/No Crush Warranty

By Terry Weinheimer Leave a Comment

No Mat/No Crush Warranty

A major complaint with carpet is matting and crushing. To address this concern, some manufacturers such as Shaw offer a No Mat/No Crush warranty on some of their carpet products. This is basically another appearance retention warranty. While most all carpets are covered by a wear warranty the problem is really not wear as synthetic fibers do not wear out, they “ugly out.” The ugly out is often matting and crushing as the carpets yarn looses its resiliency.

Carpet Texture Retention Warranty Basics

carpet texture retention warranty cri reference scale

The carpet texture retention warranty usually covers excessive loss of texture from foot traffic resulting in tuft bursting, opening or loss of twist which cannot be corrected. Under the terms of the carpet texture retention warranty the manufacturer will often have a certified carpet inspector rate the carpet using the CRI texture retention rating scale. These standardized rating scales have a range, 5 = No change, 4 = Slight change, 3 = Noticeable change, 2 = Considerable change, 1 = Severe change (A grading with a decimal indicates that the appearance fell between two grading scales. The accepted change under the terms of the carpet texture retention warranty will often be 3.0 to 3.5. It is considered a normal characteristic for the texture of any carpet to change over time. Texture retention is the ability of carpet’s tufts to retain their visible shape, as measured by the degree of bursting, opening, or untwisting of the tufts at the surface of the carpet.

Carpet Stain Warranty

By Terry Weinheimer 2 Comments

The Carpet Stain Warranty and Soil Warranty

As with other carpet warranties the carpet stain warranty may be for a certain number of years such as 5, 10 or 20 or it may be a “lifetime” warranty for the life of the carpet.

Stain resist products are designed for and generally warranted to resist stains from common food and beverages when installed in owner-occupied residences.
Soil resist products are designed for and generally warranted to resist abnormal color changes from normal foot traffic on carpets that are used for indoor residential use, and the carpet cannot be corrected.

Stain Resist Warranties for olefin and polyester will often be more liberal than those on nylon due to the differences in fiber characteristics.

Carpet Wear Warranty and Abrasive Wear Resistance

The carpet wear warranty almost always refers to wear in the terms of abrasive wear. Carpet wear is described as the actual loss of the carpet face fiber through normal abrasion (foot traffic). A carpet wear warranty will cover periods from 5, 10, or more years and some are for lifetime. Carpet wear warranties cover against becoming abrasively worn through normal abrasion. Standard percentages used to establish the amount of wear required to be considered excessive wear range between 10% and 15%. [Read more…]

Carpet Warranties Are Diverse and Confusing

Carpet warranties are diverse and often confusing to the consumer and professional alike. A fiber manufacturer may imply through a photo in an ad that a carpet will perform in a way that it may not. A salesperson may give the consumer an expressed or implied warranty by stating or inferring that a product will perform in a certain way. Fiber manufacturers, carpet manufacturers, and many dealers offer limited product performance warranties.

Express: To represent in words or to give or convey a true impression of.
Imply: To involve or indicate by inference, association, or necessary consequence rather than by direct statement.

Carpet Sidematch Problems

By Terry Weinheimer 9 Comments

Carpet sidematch also spelled side match is the appearance of a shade or hue variation between joined carpet panels. A person may see what they believe to be two shades of carpet joined side-by-side, when in actuality the shades are identical. Carpet is a man made product that goes through many processes from the time the fiber is manufactured into carpet, up through its installation. During the manufacturing of carpet a dye or texture variation may occur, resulting in an actual sidematch appearance variation. During the seaming and installation of carpet a real or perceived carpet sidematch appearance variation can also occur. [Read more…]
