| titleOfInvention | Composite fiber assembly and process and apparatus for production thereof |
| abstract | An assembly of many fibers is composed of at least two dissimilar fiber-forming polymers in whichn (1) at least 90% of the fibers have a non-circular cross-section, (2) the cross-sections of at least 50% of the fibers differ from each other in shape and/or size, and (3) at least 50% of said fibers each have in their cross-section taken at right angles to the fiber axis at least two side-by-side coalesced blocks of at least two dissimilar fiber-forming polymer phases with at least a part thereof being exposed to the peripheral surface of the fiber, at least one of the number, shape and size of the blocks varying from fiber to fiber. The assembly of fibers can be produced by extruding a molten macroblend composed of many molten phases of at least two dissimilar fiber-forming polymers through a mesh spinneret (25) having many small openings; and taking up the extrudates from the small openings while cooling them by supplying a cooling fluid to the extrusion surface of the spinneret (25) or to its neighborhood, whereby said extrudates are converted into numerous separated fine fibrous streams and solidified; wherein the macroblend is prepared, for example in a static mixer (23). by coalescing many distinct molten phases of at least two dissimilar polymers in such a manner that in a phantom cross-section of the molten macroblend taken parallel to the spinneret (25). there exist many effective continuous boundary lines between the molten phases of dissimilar polymers each of which lines has a length larger than one-fourth of the length of a partitioning member which defines one small opening in the partitioning members in the spinneret (25). |
