Carpet Cleaning

The importance of Fibre Identification

Before any job, whether it be carpet or upholstery cleaning, I carry out a pre-inspection and record the findings on my pre-inspection software.

This records fibre type, construction, age and condition and helps me to ascertain the best method to use when setting about cleaning.

Software

Even some professional cleaners do not take the time to go through the various necessary tests to identify fibres or fabrics prior to cleaning.

However, it is hugely important to know as much as you can about the fibre content to ascertain the best techniques, chemicals and temperature ranges to use.

Some cleaners might say that their experience allows them to identify many fibres and fabric construction techniques by sight but, be warned, even the ‘Old Hands’ that have been around forever can be fooled.

Some other cleaners just don’t know about it and are unlikely to unless they are properly trained and qualified.

VISUAL IDENTIFICATION:

This is the least accurate method and the one that is most likely to fool even the most experienced cleaner.

For example, acrylic is manufactured to look like wool, however acrylic fibres can also be manufactured in a velour finish and so could be confused with cotton velvet or perhaps chenille.

Generally, it is easier to visually identify a fibre after a problem has surfaced but by then it may be too late. For example, rayon / viscose velvet or velour crushes with use but even worse things happen if it is wet cleaned. The pile flattens and may never look the same again. The image below shows a piece of viscose carpet onto which water has been applied! The pile, once flattened, never returns!

Some fabrics are, however, easy to identify visually with experience. Haitian cotton, raw silk, glazed chintz and wool are pretty easy. After that, however, picking out fibre content by looking at it is very difficult, in fact almost impossible to do.

A cotton and rayon blend can be made to look exactly like silk. Nylon and polypropylene are also very difficult to distinguish in bulky weaves.

BURN TESTING:

In my pre-inspection I ALWAYS carry out a ‘burn test’. This isn’t to test how flame proof your carpet is, but to identify the fibre!

Burn Test 1

This is more accurate than visual testing, but can still be tricky. Blended fabrics, which most fabrics are, can present conflicting information during testing. However the burn test is fairly simple, and is the most commonly used test for on-location cleaning. It relies on the senses of sight and smell to ascertain the fibre type.

The test is carried out by burning a fibre or yarn sample and observing the flame colour and action, smoke, action of the burning material, odour, ash shape, colour, lustre and consistency.

You can be assured that I take the utmost care when cleaning your valuable items and for this reason the pre-inspection is a vital first step.

The Benefits of Carpet Cleaning

A lot of my time is spent cleaning carpets that are so heavily soiled that they are damaged already and there are compressed fibres in traffic lanes which no amount of cleaning will remove.

To prevent this carpets should be cleaned regularly and the following 3 points apply:-

1. PROFESSIONAL CLEANING WILL HELP TO MAINTAIN THE LIFE EXPECTANCY OF YOUR CARPETS

All carpets need regular professional cleaning in order to maintain their expected lifespan. Accumulated soil and grit are major causes of wear and tear, which results in reduced carpet life. Every time you step on your carpets, you grind dirt into the fibres. This cuts the fibres, just like using a knife. This ‘cutting’ causes your carpets to wear out faster.

Regular vacuuming will go some way to prolonging the life of your carpet, however, on its own it is simply not enough. Professional cleaning will remove the soiling deep within the pile that regular vacuuming cannot reach.

2. PROFESSIONAL CLEANING WILL REMOVE POLLUTANTS FROM YOUR CARPETS

There are many contaminants in indoor environments and, because they are unable to escape, they have to end up somewhere. That place is usually the carpet. A carpet is actually a very good retainer of pollutants, trapping allergens and dust efficiently, reducing the number of particles in the air and significantly improving indoor air quality. Some of these pollutants will be removed during a regular vacuuming routine but it is important to bear in mind that, unless carpet is regularly professionally cleaned, pollutants retained deep within the fibres will eventually be transferred back into the air.

3. PROFESSIONAL CARPET CLEANING HELPS TO PREVENT INSECT INFESTATIONS.

Moths and carpet beetles are known to digest protein fibres such as wool, silk and specialty hair fibres, but these insects will also attack synthetic fibres if they contain protein substances. This means that carpets made from nylon, polyester and other synthetics can be damaged if they contain food or beverage stains, blood, urine, perspiration or other sources of nutritional protein.

The most effective way to prevent an infestation and inhibit growth is to keep floor coverings clean. Regular professional cleaning will remove the source of nutrition, meaning that the carpet will no longer provide the ideal habitat in which insects are able to survive and thrive.
