Putting a Value to Softness with the VantageNX.

The quest for softness of an end user product can be quite subjective. However, when paired with MAP4 software, the VantageNX Universal Testing Machine can be used to calculate an objective softness value. Compression/softness results of high loft nonwovens can be evaluated to measure a combination of factors including sample loft, thickness, compressibility and structural softness. The test measures the material from the compression phase all the way through the relaxation phase of the material.

Tensile test results and the importance of sample preparation.

Cuts made to prepare a sample for tensile testing are critical to the accuracy and quality of the results.  Preparing a sample without jagged edges or nicks is vital to ensure accurate tensile results. Those imperfections will affect the ability to provide consistent tensile results for the physical properties of the specimen.
