COLOUR MATCHING
Carpets are produced in batches. Whilst the recipe used by the dyer remains constant, and is followed to the letter, in each separate production the colour reproduction will vary from batch to batch. However production is matched back to the original or master sample to ensure that the colour remains within a commercial tolerance.

To ensure perfect colour matching it is advisable that a single width be used in any installation requiring exact colour matching. Carpets which are laid with the pile travelling in different directions, even though they be from the same batch will appear not to match. The samples held by individual retailers may not be from the same batch as current production and therefore should be used as a guide and not an exact colour match.

SHEDDING
All cut pile carpets will lose short fibre, which is created during production when spun yarn is cut for tuft formation. These fibres fall onto the surface of the pile and appear as fluff. The effect varies with yarn type and may be removed without detrimental effect upon the carpet by vacuum cleaning.

PULLED LOOPS
Pulled loops occur only in looped pile carpet where one or more loops in the continuous pile is pulled through the primary backing of the carpet. This is usually due to some local condition, possibly some sharp object which has caught in a loop in situ and has resulted in a pull. Pulled loops are easily dealt with by trimming the offending end level with the rest of the pile. They should not be left as this could result in further loops being pulled and developing into a ladder. 

SPROUTING
Occasionally an odd tuft or two can work its way to the surface and stand proud of the rest of the pile. This is probably due to one end of the tuft being longer than the other i.e. J shaped tuft instead of V shaped. Remedial action merely requires that the offending tufts be scissor trimmed level with the rest of the pile. They should never be pulled out.

SHADING
Shading occurs because the pile of the carpet has become crushed, flattened or brushed in a different direction to the natural lie of the pile whilst in situ. This causes light reflection at differing angles resulting in the creation of light and dark patches on the carpet. This will occur on all pile fabrics but can be more noticeable on plainer carpets because the shadows created by pile pressure will not be disguised by a heavy pattern or design.

STATIC
Carpets do not produce static but like other household fabrics and objects have the capacity to store it. Static is caused by the build up of static electricity upon people in a dry environment and is discharged when a person makes contact with an object which can conduct electricity (i.e. door handle or filing cabinets, etc).

The static charges will vary in intensity depending upon the individual, air humidity and the contact materials. Static is more usually associated with synthetic materials as they do not retain moisture very well but it can and does occur with wool in very dry room conditions. Preventative measures include the introduction of moisture into the room or in situ carpet treatment.

FADING ON WOOL
Carpets made from wool can and do fade in use. The degree of fade can vary depending on the colour chosen and the local conditions to which the carpet is subjected. Fading can be caused by exposure to ultra violet light which is found in daylight, but is accelerated when sunlight shines directly onto the carpet. This has the effect of lightening or bleaching the colour just as exposure to sunlight will lighten human hair.

Protection should be given to carpets exposed to such conditions just as you would protect other furniture or fabrics. 

PILE REVERSAL
Like shading, this occurs when the pile or nap of the carpet changes direction and thus reflects light at different angles showing the effects of shading which can become permanent. It is also described as watermarking. Like shading it can be more apparent on plain carpet because heavy patterns can disguise the effects. It can occur quite quickly after installation.

A tremendous amount of research has been carried out over many years by many institutes to determine the cause of this phenomenon but none of it has proved conclusive. There is no commonly known manufacturing process which can cause or cure this phenomenon and therefore it is not a manufacturing fault.

INDENTATIONS
When a carpet is subjected to a heavy point load, such as under the legs of furniture, it is unreasonable to expect the carpet not to indent. Usually, the longer the load is in place, the longer will be the time for the pile to recover. In the case of very heavy loads in place for a considerable time, the recovery time can be very considerable.

It must be remembered that it is not only the pile of the carpet that becomes indented. The underlay will also indent and the backing of the carpet may also distort into theindentation in the underlay. Some underlays will recover well and some less well depending upon their composition, thickness, density etc. The use of cups below furniture legs can spread the load and the net result is a larger area of less deeply indented carpet.
