Much has been written about crimp and the relationship with curvature, frequency and microns, as well as curvature and compression. Many of the comments you hear are fact and fiction. We have heard the crinkle theory, the popcorn theory and various statements like “crinkle provides bulk which is created by the air pockets” (processors have concerns re the lack of bulk in Huacaya fibre – products too heavy) and of course that “crimp frequency is a reliable indicator of fineness”.
I will demonstrate quite clearly that well-defined crimp is more consistent in its relationships with crimp frequency, curvature and micron. more »
