Standard Test Method for Fiber Cohesion in Roving, Sliver, and Top in Dynamic TestsMore info
1.1 This test method describes the measurement of fiber cohesion as the dynamic cohesive force required to maintain drafting in rovings, slivers or tops when they are subjected to stress induced by passing between pairs of drafting rolls of different surface speeds. The cohesive force is converted to cohesive tenacity based on the linear density of the material.
Note 1: For static tests refer to Test Method D2612.
