Abstract:
A hollow fiber fabric comprising hollow fibers having a high hollowness ratio of at least 20% and composed of a polymer of a single composition, and the hollow fibers having slits as traces of a removed polymer and the slits being formed in the longitudinal direction of the fibers in such a state that the slits communicate to hollow portions. The fabric is produced by treating a fabric comprising hollow fibers having a high hollowness ratio of at least 20% and composed of a polymer of a single composition with a solvent or solution which dissolves the polymer, to partially dissolve the polymer at low orientation and/or deformation strain concentrated portions, to form slits as traces of a removed polymer in such a state that the slits communicate to hollow portions, along the longitudinal direction of the hollow fibers.
Abstract:
The set of fibers in sheet form has conducting fibers in such an amount, with respect to the non-conducting fibers, that there is electrical continuity. The set of fibers may be incorporated in a fabric by holding the non-conducting fibers (10) together in the weft and the warp of the fabric with the non-conducting fibers (11,12).
Abstract:
Staple yarns of cotton and high modulus fiber are wet and then dried under tension to provide warp yarn for durable, abrasion resistant fabrics.

Selon ce procédé, l'âme réalisée en filé de fibres longues, de préférence obtenues par craquage, est montée en torsion pendant l'opération même de filature réalisée sur continu à filer à anneaux sans que soit atteint son coefficient de torsion critique αʺ o , la couverture de ladite âme étant réalisée en fibres longues ou en fibres courtes. Le coefficient de torsion du fil d'âme se situe entre 20 et 85.
Abstract:
Polyester conjugate crimped yarns prepared by conjugate spinning (1) an A component substantially comprising polybutylene terephthalate and (2) a B component substantially comprising polyethylene terephthalate at a weight ratio of 30:70 to 70:30 in a side-by-side or eccentric sheath-core arrangement, rendered crimpable by false twisting to a degree of crimpability TC 10 of 8% or more when subjected to a boiling water treatment under a load of 10 mg/de. The polyester conjugate crimped yarn can be obtained by subjecting the conjugate yarn to single-heater false twisting under the conditions which satisfy the following relations: where TW is the number of false twists (T/m); De is the total denier of the yarn after false twisting: T is the temperature in °C of the false twister heater; [η]B is the intrinsic viscosity of the B component. Stretch woven fabrics having a stretch percentage of 15% or more can be obtained by weaving the above-mentioned polyester conjugate crimped yarns.
Abstract:
A power transmission belt 10 of improved manufacture includes a novel reinforcing fabric 4 in the inner portion of the compression section 3 of the belt. The fabric 4 is formed of yarns 20 having a low coefficient of thermal contraction and a high bias elongation to break. The yarns 20 are formed of a mixture of natural and synthetic resin fibers and are subjected to heat treatment to effect the improved low coefficient of thermal contraction and high bias elongation to break.
Abstract:
A textile printing is more appropriately performed on fabrics made from various materials. A textile printing method of performing textile printing on a textile printing obj ect 100 which is a fabric includes a dye adhesion process S102 of adhering particles of a polyester resin which is a particulate polyester resin, and a dye to the fabric, and a heating process S104 of heating the textile printing object 100 having the particles of the polyester resin and the dye adhered thereto, thereby developing the color of the dye while fixing the particles of the polyester resin to the textile printing object 100.
