The structural evolution in fibers produced by high-speed fiber spinning of Polyethylene 2,6 naphthalene dicarboxylate (polyethylene naphthalate) was investigated. The fibers were found to remain amorphous at speeds up to 2500 m/min, and subsequent increases in speed resulted in highly oriented crys

High-density polyethylene (HDPE) fibers, obtained from a melt-flow rate (g/10 min) of 11 and 28, was produced by a high-speed melt-spinning method in the range of take-up velocity from 1 to 8 km/min and from 1 to 6 km/min, respectively. The change of fiber structure and physical properties with incr
The high-speed melt spinning of sheath/core type bicomponent fibers was performed and the change of fiber structure with increasing take-up velocity was investigated in comparison with the results of our previous study. Two kinds of polyethylene, high density and linear low density (HDPE, LLDPE) wit
Linear low-density polyethylene (LLDPE) fibers, obtained from the meltflow rate (g/10 min) of 45 and 50, which were polymerized by a metallocene catalyst and a Ziegler-Natta catalyst, respectively, were produced by a high-speed melt-spinning method in the range of take-up velocity from 1 to 6 km/min
