Everything You Need To Know About Carpets

You’ve got questions, we know!

Many of us have carpets in our homes but there are so many unanswered questions. The good news is, we’re here to answer them.

… Including things that could go wrong with your  carpet and how to fix them.

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.

Pulled loops

Pulled loops occur only in looped pile carpet where one or more loops in the continuous pile are 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.

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. This excess fibre is only a small fraction of the total fibre contained in the carpet.

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 the 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 electricity upon personnel 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.

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’. This can happen to every carpet construction be it Axminster, Wilton, Tufted, Hand Woven, Persian, Chinese, Indian and even Coir Matting. 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.

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 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. Wool is after all animal hair.

Flattening

Flattening will occur as a result of traffic, which eventually flattens the pile particularly in the main areas of use. All pile fabrics will flatten to a greater or lesser degree, dependant on the amount of traffic to which it is subjected and the construction (tuft density/pile fibre/height/weight) of the product concerned.

Dust

Dust which is carried on draughts can soil carpets in various ways, apart from the obvious soiled edges, at gaping skirting boards for instance, dark lines appearing on the surface might suggest airborne dust vacuum-drawn through poorly fitted floorboards. Sometimes the shape of the floorboards can be seen quite clearly. Air borne dust sometimes shows itself as spots on the carpet, this is due to the air carried on a draught under the carpet escaping through minute holes both in the underlay and the carpet, leaving dust deposited on the pile much like a filter action. In such installations, the use of a lining paper is essential as a preventative measure.

 

It is the responsibility of the retailer to advise the consumer, when the carpet is measured, of any poorly fitting doors, skirtings, or floorboards and the consumers responsibility to ensure any remedial work to seal draughts, is carried out before the carpet is fitted, if a resulting complaint is to be avoided.
