Patent number: 5758697Abstract: A weaving method that imparts a 1/f fluctuation to the weave pattern. Adjacent and different numbered groups of different yarns, for example black yarn and white yarns, are alternately arranged in contiguous reed dents. The sequential number which is associated with each group manifests a series of numbers which effect the 1/f fluctuation. Following separation of the warp yarns into two sets by raising and lowering of healds to form a shed and passage of weft yarns therethrough, a woven fabric with a stripped 1/f fluctuation in the warp direction is created.Type: GrantFiled: May 8, 1996Date of Patent: June 2, 1998Assignees: Nisshinbo Industries, Inc., Toshimitsu MushaInventors: Toshimitsu Musha, Yuichi Yanai, Shoji Takagi, Shu Ono

Patent number: 5727600Abstract: A weaving method that imparts a correlation of a 1/f fluctuation to the texture pattern of a woven fabric by passing warp yarns through a plural number of healds in a specific numerical sequence. The healds are then manipulated to separate the warp yarns into two sets to form a shed therebetween through which a weft yarn is inserted. For one texture pattern, warp yarns are threaded in groups in numbers corresponding to the values of a numerical sequence with a 1/f fluctuation through one set of healds. For another texture pattern, warp yarns are threaded in groups through another set of healds so as to alternate with the first groups, thereby weaving a plural number of texture patterns into the woven goods, with the overall texture design having a 1/f fluctuation.Type: GrantFiled: May 8, 1996Date of Patent: March 17, 1998Assignees: Nisshinbo Industries Inc., Toshimitsu MushaInventors: Toshimitsu Musha, Yuichi Yanai, Shoji Takagi, Shu Ono
