This invention provides methods by which any staple fiber or continuous filament can be stretch processed such that the fiber's internal molecular structure is oriented along the fiber strand axis. With only the simple continuous and simultaneous ap- plication of a single dynamic stretching stress, and a single dynamic twisting force, that is correct and precisely controlled relative to each other and to its input flow rate, every individual fiber is effectively and uniformly stretch processed. Such individual fib- er's net strength properties gain and desirable quality characteristics improvement as well as their continuous cross-sectional un- iformity are substantially enhanced for their greater utility. The methods of this invention can substantially improve the stretch processing uniformity of continuous filament fiber and hold its substantial original extruded evenness allowing multiple series treatments providing substantially improved stretch processing effectiveness and uniformity.
