Abrasion resistance

from Wikipedia, the free encyclopedia

Abrasion resistance is the resistance of a textile fabric (e.g. upholstery fabrics, upholstery fabrics) to abrasion under certain conditions, which is assessed according to the change in the appearance of the goods or significant properties. It is determined in so-called abrasion tests, as is the abrasion resistance of paint or wallpaper .

Furniture and upholstery fabrics

According to the Martindale method , a test fabric and a fabric are rubbed against each other. The abrasion resistance is given in abrasion cycles. Abrasion tours are considered a unit such as B. grams or centimeters. The higher the number of tours, the more durable the fabric is. The following abrasion tours are recommended:

  • 10,000 cycles for private households with less use
  • 15,000 rubs for private households with regular use
  • 20,000 rubs for public environments with regular use
  • 30,000 rubs for public environments with intensive use
  • 40,000 rubs for public environments with very heavy use

A fabric that is used on soft upholstery is also more resistant to wear and tear than the same fabric on hard upholstery.

Colours

The DIN standard DIN EN 13 300 has been in effect since November 1, 2001 for plastic emulsion paints and other water-based paints for indoor use. The durability of the paint, previously referred to as abrasion or wash resistance, which was tested with a precisely defined brush until the surface shone through, whereby paint referred to as abrasion had to withstand around 5,000 scrubbing movements and so-called washable paint withstood around 1,000 brush treatments , is now uniformly referred to as wet abrasion resistance .

Now the loss of layer thickness is measured and the result is given in micrometers .

  • If the loss of thickness is less than 5 micrometers after 200 strokes, it is class 1.
  • At 5 to 20 micrometers layer thickness abrasion as class 2.
  • If the layer thickness has lost 20 to 70 micrometers, it belongs to class 3.
  • If there is even more loss, the group is divided into grades 4 and 5.

Wallpaper

In the case of wallpaper, symbols indicate its resistance to washing and scrubbing. Symbols with one or more waves indicate water resistance, with three waves indicating a highly wash-resistant wallpaper that can also be washed off with a light soapy water . In addition to the wave, the abrasion resistance is symbolized with a brush. Here, too, the more waves, the more abrasion-resistant the wallpaper. " With highly abrasion-resistant wallpaper, almost any stain can be removed. "

Classification

There is no standardized classification. However, synthetic fabrics are usually more abrasion-resistant than natural materials.

Impact on the environment

According to a study, published in the journal "Environment Science and Technology" rub washing machines more than 1,900 microparticles - in diameter smaller than a millimeter - per wash of fleece fabrics made of polyester - and acrylic textile fibers from. They are not held back in sewage treatment plants. If these microparticles get into the sea via sewage, they form part of the plastic waste in the oceans . Such particles were found in the sediment of 18 beaches worldwide, not a single sample was free of them.
