| Number | Title | Issue Date |
| 5042122 | Method and system for spreading a tow of fibers A method and system for spreading a tow of fibers (12) using the acoustic energy from a speaker (16a) or other vibrating device for a gaseous medium over which the tow passes as the fibers zig-zag between rods (16d) is described. The spread two of fibers ... | 08/27/1991 |
| 5026603 | Staple fibers and process for making them Staple fibers having a crimp frequency in the range of 3 to 6 crimps per centimeter are mae by a process including a co-crimping step in which conductive and nonconductive filaments are crimped together.... | 06/25/1991 |
| 4667463 | Process and apparatus for making fasciated yarn A process and apparatus are provided for manufacturing a fasciated yarn having uniform yarn construction and high strength. The process comprises subjecting fibers to a draft cutting step, at least one amendatory draft cutting step and a yarn formation st... | 05/26/1987 |
| 4583266 | Process for preparation of discontinuous filament bundles and sharp-ended filaments A process for the preparation of discontinuous filament bundles, which comprises applying a drawing force and/or a shearing force to a bundle of continuous filaments while or immediately after contacting the bundle of continuous filaments with a medium ma... | 04/22/1986 |
| 4569811 | Method of making a staple-fiber band A staple-fiber band is made by first spinning synthetic-resin filaments with spinnerets and drawing the filaments as roving at a predetermined feed speed from the spinnerets. The roving is then cooled without greatly stretching it so it has relatively hig... | 02/11/1986 |
| 4547934 | Crimped staple fiber Process and apparatus are provided for the preparation of crimped staple fibers. By automatically adjusting the pressure on the stuffer crimper box discharge means as a function of staple cutter speed, a crimped staple product with uniform fiber-to-fiber ... | 10/22/1985 |
| 4434530 | Process for the production of highly shrinkable split tows of acrylonitrile polymers High-shrinkage stretch-broken tows of acrylonitrile polymers are obtained by fixing with saturated steam at maximum temperatures of 140° C. after drawing and before stretch breaking and stretch breaking at a draft of at least 30%.... | 03/06/1984 |
| 4221838 | Crimped thermoplastic fibers The crimped products are produced having a more permanent bulkiness which resists deterioration during further processing and subsequent use. Such products are disclosed having deposited on the surface of the fibers a thin coating of a finishing agent com... | 09/09/1980 |
