A Study on the Compression of Sliver - Dynamic Compression Mechanical Properties of Sliver Masses-

For the purpose of applying the dynamic characteristics of sliver to the automatic control of sliver linear density in the spinning process, the unidirectionally oriented sliver masses were made and used to perform the experiments of compressional load transfer for the dynamic compression. The following dynamic characteristic behaviors of sliver masses were made clear through this study. It was shown that the phase angle of the system was proportionally increased with the increase of input strain frequency so that the dynamic compressional behavior was able to be interpreted as lst order control element of process analysis. Also it was shown that the phase angle was increased with the decrease of dynamic compression modulus when the specific volume of silver masses were increased. The dynamic compression moduli were decreased in the order of polyester, wool, and cotton sliver masses.
