Flory tests explained
Abrasion resistance as a result of yarn-yarn interaction can be measured at Senbis. Both dry and wet yarns can be used in combination with our equipment under different loads and angles.
For a measurement, a piece of yarn is applied on the apparatus as seen in the figure below. A tension weight is attached to one end of the yarn. The other end is attached to a crank that draws the yarn back and forth. Abrasion will occur at the interwrapped yarn region which eventually leads to breakage of the yarn. The amount of cycles to failure are counted and are a measure of abrasion resistance.
Other standards are available upon request.
