New definition to softness by Lenzing

micromodal_softnessLenzing is demonstrating its innovative expertise and presenting a new method to measure softness together with the German instrument manufacturers, Emtec Electronic.


Softness: the key to comfort

Fashion-conscious consumers have changed their purchasing behavior. The “look” itself is no longer the only important factor. The comfort that fashion should offer now also has priority. The softness of the textile is an important parameter for comfortable clothing. In fact, softness is a basic pre-requisite for comfortable clothing. The softness has to be perceived by the wearer to trigger the decision to purchase the garment. How people perceive softness is, however, something that differs from person to person and is determined by how the textile and the skin interact.

New method to measure softness

A group specially formed at Lenzing Research, which devotes its research to physiological

properties, searched for easier methods to measure softness. “In the search for existing measuring methods to test softness, we examined related industries and found an interesting instrument which appeared suitable to measure the softness of textiles,” Mohammad Abu Rous, head of the tests, explains. The device is well known in the paper tissue industry and measures the softness of different products in this field. More than 100 fabrics were used for the test on Lenzing fibers to see whether this device can be used for textiles. “Following an intensive test phase, we approached Emtec Electronic to share our results with them and to arrange co-operation on further tests,” Abu Rous goes on.

micromodal_softness-1Tests were then performed together to prepare a suitable algorithm for the device software which determines softness using a Sound-Spectrum. “In our capacity as instrument manufacturers it is important for us to tread new ground. Lenzing’s textile know-how was instrumental in developing our ‘Tissue Softness Analyzer’ further to become a ‘Fabric Softness Analyzer’,” Alexander Grüner from Emtec Electronic explains.

Lenzing’s Definition of Softness
Lenzing has already created a method to give a new definition to softness in textiles. Using the softness measuring device from Emtec Electronic and the well-known ring method, it is possible to show that the higher the amount of Lenzing Modal® used in the textile, the softer it becomes. The test result itself shows that MicroModal® is the softest fiber of all the fibers tested. “The test method should quickly depict the degree of softness of fabrics with Lenzing Modal®, to help customers communicate softness at point of sale,” Mommer comments.
