Abstract
We have measured breaking strength and breaking and investigated slipping work per unit weight of cotton turts delivered from blowing processes. The longer the test lengths of the tufts. the greater the breaking strength, breaking and slipping elongation, and the less the work done.
Showing those values in the order in which they decrease, then the following results are obtained :
(1) Breaking elongation : C.Sa, C.W., R.C ., H.B.B.∼F.S. lap.
(2) Slipping elongation : H.B.B.∼F.S, lap. R.C., C.W., C.S.
(3) Breaking strength : R.C., H.B.B.∼F.S. lap.
(4) Work : C.S., R.C., C.W., H.B.B.∼F.S, lap.
The following can be concluded :
(a) The fibers in R.C. tuft ale oriented partly.
(b) The fiber orientation in C.W is in a special form.
(c) The opening action of a hopper-type opener was not as good as expected.
