TEXTILE
Textile Testing is the term for a whole series of tests that examine the physical, mechanical and chemical properties of textiles. These tests are sometimes done before a textile goes into widespread use, or they’re done on textiles arriving into the markets.
Methods of Textile Testing
There are many textile tests. Some of them are physical tests, in which a sample of textile material is examined closely for feel and appearance. Such tests are done on individual fibers or strands of material and on yarns, threads made of several fibers twisted together. Textiles are also subjected to light and other elements to see how they react. Some of these tests are done in a weather-ometer, a machine that tests for weathering and lightfastness of textiles. It’s basically an enclosed box. Textiles are placed inside and subjected to conditions replicated from the natural environment.
Mechanical tests are those in which textiles are subjected to different pressure and stressors, usually in specialized testing machines. These include tests to measure breaking strength, the force needed to break a fabric under tension. Such tests can ensure fabrics are strong enough to maintain integrity even when under great stress. Other tests gauge tearing strength, or the strength required to make an already existing rip or tear worse. And abrasion tests determine how quickly a textile wears out when it’s rubbed against another surface. Such tests make sure that fabrics used in products like parachutes and car seat belts won’t break when needed most to keep the user safe.
Importance of Textile Testing
The most obvious reason is that it allows companies, consumer groups and the government to make sure textiles are safe, of good quality, and that the customer is getting what they are paying for. Textile products are made around the world, and sent to markets around the world. Testing ensures that something harmful or illegal isn’t slipping through the regulatory cracks.
