Martindale’s Test

A tested fabric is put in a special machine between fabric or sandpaper discs which are used to rub a tested fabric under permanent pressure ratio. Depending on what the strength of the fabric should be, different kinds of rubbing can continue without interruption for many hours or days. Fabric resistance to abrasion is expressed in cycles in Martindale scale (according to PN-EN ISO 12947-2:2000). Fabrics with the resistance to abrasion over 30 000 cycles in Martindale Test are fabrics with a high resistance to abrasion. Fabrics with the resistance to abrasion over 50 000 cycles are fabrics with a very high resistance to abrasion.

Tensile strenght test (ISO 13934-1)

This method is used in textile products (fabrics) testing. It is possible to use this method to obtain and describe mechanical characteristics of fabrics produced with the use of other technologies of production. It is not common to run tests on stretching artificial fibre fabrics, geotextiles, nonwoven fabrics, fabrics, textiles, fiberglass fabrics and fabrics made of carbon fibres or polyolefin fibres yarn. This method describes the procedure of testing which allows to present the maximal strength in Grab test both in atmospheric or moistened conditions.

Colour fastness to light test

Colour fastness to electric light: it is a fading test in the light of an arched xenon lamp. There are five methods of irradiating samples and blue woolen patterns and the conditions of irradiating in a camera with an arched xenon lamp which is coolen with water or air. The size of samples and patterns are established What is more, colour fastness to electric light is measured on the eighth degrees of the scale in comparison to the analysis of the colour changing. In order to avoid problems with remembering various results of the methods, it is worth to pay attention to categories to which a particular test belongs to. An A category is the best so fabrics, which obtained this category in most tests are durable and resistant to light.
