ABSTRACT:
This invention provides methods by which any staple fiber or continuous filament fiber can be stretch processed similiar to continuous filament fiber stretch processing methods heretofore used, in that the fiber's internal molecular structure is oriented along the fiber strand axis, except substantially twisting as well as substantial stretching forces are employed. With only the simple continuous and simultaneous application 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 fiber's net strength properties gain and desirable quality characteristics improvement as well as their continuous cross-sectional uniformity are substantially enhanced for their greater utility, as are fabrics and other products produced from such treated fiber. This invention has been used to increase the tensile strength of cotton to more than 60 grams per tex (1/8 gauge) through simple dry mechanical fiber stretch processing. There are substantial advantages available through the use of this high tenacity cotton fiber. Other staple fiber can be similarly improved. 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. This invention lends itself well to integration into normal production processes.
