The hardness test: abrasion tours of furniture fabrics
Furniture fabrics - they are the trend-oriented designers with an almost unlimited selection of patterns and designs for covering furniture seats, backrests or entire sofas. The loyal companions on which one should feel comfortable. That certain something in the living room, the stylish accents in the completed four walls. Exuberant praise for a thin layer of fabric? If you look at what these fibres have to go through in order to be considered a hard-wearing product, you can pay tribute to furniture fabrics.
After all, how do you know which furniture fabric is best suited for which area? private and commercial use are two different pairs of shoes and differ again in the respective use of the furniture fabric. In order to be able to offer the buyer an individual and suitable product on the one hand, but also to ensure a certain quality standard for furniture fabrics, a separate testing procedure has been established in practice: the classification according to so-called abrasion tours for furniture fabrics.
But what exactly are abrasion tours?
Abrasion tours are part of the so-called Martindale process, which is used to determine the abrasion resistance of furniture fabrics. This involves rubbing a sample of the fabric under test against a wool fabric under a given weight load in order to realistically simulate natural consumption. This determines a so-called "wear rate", which indicates when the furniture fabric starts to wear out. As soon as two threads of the test material wear out, e.g. due to tearing or obvious decay, the test is finished. The result of these abrasions is given in the Martindale unit and is a guideline for the use of the furniture fabric with regard to its wear. Over time, different guideline values have been established for the different stresses, which are classified according to abrasion tours.
10,000 - 15,000 abrasion tours: Use in private areas (e.g. living rooms)
25,000 - 35,000 abrasion tours: Use in commercial areas (e.g. offices)
30,000 - 40,000 abrasion tours: Use in public areas (e.g. trains, buses)
Due to the high load, control stations of the police or emergency services even require an abrasion resistance of 200,000 - 500,000 abrasion tours. In addition to furniture fabrics, paints and wallpapers are also tested for abrasion resistance, but not with abrasion tours.
And what is the difference between abrasion tours and Martindale?
Often the mistake happens that the terms Martindale and Scheuertouren are used as synonyms for each other. However, the difference between the two terms lies in the fact that the abrasion tours are part of the direct test procedure for furniture fabrics in order to determine their abrasion resistance. Martindale, on the other hand, is the unit in which the final result of the test is given. The common feature of both terms is that the number value is not converted. So 10,000 furniture tours = 10,000 Martindale.
