Abstract: A knitted fabric structure that includes a piezoelectric yarn having a piezoelectric material that produces a surface potential by input of an external force from an outside of the piezoelectric yarn; and an elastic yarn having stretchability knitted together with the piezoelectric yarn, wherein the piezoelectric yarn has a mixing ratio of 5% or more based on a whole of the knitted fabric structure.

Abstract: An undergarment is provided that favorably adheres to the skin and has superior shape retention. The undergarment according to the present invention is an undergarment that is comprised of a fabric having a woven structure, a knitted structure or a non-woven fabric structure, wherein the fabric contains a filament yarn A having a filament diameter of 10 to 1000 nm and a filament yarn B having a filament diameter greater than 1000 nm, and the filament yarn A is exposed on the side that contacts the skin.

Abstract: [Problem] There are provided an antislipping tape having an excellent antislipping effect, and comfortable to the skin, and textile products including the antislipping tape. [Means for Resolution] Using a filament yarn A with a single filament diameter of 10 to 1000 nm, a cloth having a woven fabric structure or a knitted fabric structure is obtained. Using the cloth, an antislipping tape is obtained. Then, using the antislipping tape, textile products such as brassiere are obtained.

Abstract: A knitted/woven fabric of polyester fibers is produced from a polyester polymer obtained by condensation-polymerizing an aromatic dicarboxylate in the presence of a catalyst which comprises a mixture of a titanium compound ingredient (A) comprising a titanium alkoxide and at least one product of the reaction of the titanium alkoxide with a specific carboxylic acid or anhydride thereof and a specific phosphorus compound ingredient (B) and/or comprises a product of the reaction of a titanium compound ingredient (C) with a specific phosphorus compound ingredient (D). The knitted/woven fabric obtained has a satisfactory color tone (low value of b*) and is excellent in suitability for knitting/weaving and dyeability.

Abstract: A flat multifilament yarn knitted fabric having excellent bulkiness, drape, and water•sweat-absorbability is a knitted fabric comprising multifilament yarns each comprising a plurality of flat cross section shape-having filaments comprising a fiber-forming thermoplastic polymer as a main component. In the above-described flat cross section, three or more expanded portions expanded toward the outside of the longitudinal central line of the flat cross section per half side of the flat cross section, and two or more constricted portions formed between the expanded portions per half side are approximately symmetrically formed on both the sides of the longitudinal central line with respect to the above-described longitudinal central line.

Abstract: A knitted fabric having a triple knit ply structure, and is useful for underwear clothes which need high lightness and warmth, has a front surface knit ply having a yarn knit structure, a back surface knit ply having a yarn knit structure and a binding intermediate knit ply constituted from stitching yarns through which the front and back surface knit plies are tuck-stitched together, the stitching yarns are constituted from hollow fibers (for example, hollow filaments having a percentage of hollowness of 10 to 50%).

Abstract: A nickel-hydrogen secondary battery is disclosed wherein a long life is assured, an improved self-discharging property in a high temperature storage and the inhibition of increase in inner pressure of the battery in the occasion of over-charging can be realized. The nickel-hydrogen secondary battery comprises, a case, a paste-type positive electrode accommodated in the case and containing nickel hydroxide and a polymeric binder, a paste-type negative electrode accommodated in the case and containing a hydrogen-absorbing alloy and a polymeric binder, a separator accommodated in the case in so as to be interposed between the positive and negative electrodes, and an alkali electrolyte accommodated in the case.
