Abstract
Method for determining whether textile staple fibers having crimp therein, either natural or man-made, have a weighted-average cohesion number of from 14.2 to 31.75 centimeters (5.6 to 12.5 inches) by initiating gas impingement contacts at successively increasing different pressure levels against a carded web of staple fibers to cause in the carded web the formation of visible bulges until the bulges are eventually ruptured 80 to 100% for a particular pressure level, and then recording the pressure and number of ruptures from each level and determining therefrom the weighted-average cohesion number.
