Abstract: The composite elastic yarn may be made from a wide, stretchable textile fabric or stretchable knitted fabric. A composite elastic yarn is obtained by drawing an elastic yarn 11 at a first draft rate to prepare a precursor composite elastic yarn with an inelastic yarn 31 and further drawing the precursor composite elastic yarn at a second draft rate of a value smaller than that of the first draft rate to make a composite with the removable inelastic yarn 31; and stretchable textile fabric and stretchable knitted fabric fabricated using this composite elastic yarn.

Abstract: A warp backed weave denim with excellent stretchability. A warp backed weave denim having a stretchable structure of twill weave or satin weave, comprising warps doubled to be exposed on front and back surfaces of a weft yarn, and the weft yearn is made of polyurethane fiber filament core spun yarn.

Abstract: 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.

Abstract: 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.

Abstract: A weaving method for woven goods in which the warp yarns are disposed among reed dents of uniform spacing in a reed according to a sequence of numerical values having a 1/f fluctuation, thereby imparting a 1/f fluctuation to the arrangement of warp yarns.
