Abstract
In this report, the opening energy of cotton tufts in Platt type Blowing Process was measured and the relation between the type of breakage of Blowing machine and the opening energy of tufts is descussed. The measuring apparatus of the opening energy of tufts consists of nip roller, taker-in roller, torque detector, strain amp., integrator and others. It is a kind of entanglement tester.
The entanglement of cotton tufts increases in Hopper type machine while it decreases in Cylinder or beater type machine.
Thus the opening energy of cotton tufts is larger in Hopper type machine than in Cylinder or beater type machines. The increase in the opening energy of tuft is accompanied by the increase in the un-opened nep like tufts in fleece on the taker-in roller.
Hopper type machine contains much un-opened nep like tufts in the fleece than Cylinder or Beater type machine. It was showned experimentally that the degree of the contact of tufts under sligrt compression influences on the opening energy of cottou tufts.
