INTERIORS Commercial benefits


Catherine Helliker of Danfloor UK explains the many factors that specifiers must consider when selecting a high-performance commercial carpet


T


he floors of any building, whether commercial or residential, will be the surface that has most impact from footfall as well as routine cleaning and maintenance. It’s therefore no surprise that floors are usually the first surface to reflect wear and tear. As such, it’s important to invest in floors which will keep pace with the demands of the particular environment in question. There are hundreds of flooring options to choose from, and when it comes to selecting carpet there are so many which appear the same, but due to their composition, may not perform in the same way, or last as long. There are a number of elements to consider and the following will give an indication of what to look for when specifying a high-performance commercial carpet which still delivers a touch of comfort and luxury.


Pile composition To ensure the best possible product and protect your investment, one thing you can look at is the pile height. In a commercial environment the pile height should be no greater than 5 mm, to allow the use of wheeled items such as trollies and wheelchairs. Shorter pile height also makes for a more durable carpet, which is easier to clean and less prone to crushing. The total pile weight should exceed 1000 grams per square metre and for tufted carpets the pile density should be greater than 180,000 tufts. As a result, the greater tuft density will also resist crushing and increase longevity. Finding such a combination will provide you with a carpet that will perform, and last in such demanding environments.


Yarn shape and structure It’s important to select a carpet constructed with a ‘trilobal’ yarn, which acts like a prism to refract light and defuse the visual effects of soiling. A heat set twist yarn will also hold its appearance longer than other yarn types due to the finishing process, which help to minimise yarn fraying.


ADF MARCH 2019 Dyeing techniques


There are many dyeing techniques for producing the wide variety of colours and designs available on the market. Dyeing methods affect carpet performance and stain resistance, so it’s important to understand the difference between two of the most common techniques – solution and piece dyed. In solution dyeing, colour is added to the liquid state of the fibre components, before the fibre is actually produced, meaning that the colour is found throughout the carpet fibre; a little like the appearance of a carrot. The solution dye method produces the most colourfast carpet yarn because the dye is added during the manufacturing process before the fibres are extruded, meaning the colour is locked in. As a result solution dyed fibres are particularly resistant to prolonged exposure to UV light.


Piece dyeing is done after the carpet is


made. This method yields bright tones and more of a variety of colours, however the dye only penetrates the outer surface of the fibre, like the appearance of a radish.

Solution dyed carpets maintain their colour even with the use of harsh cleaning chemicals such as bleach
