Benefits of technology

[0006]The present invention provides a fabric exhibiting excellent surface conductive performance in the whole direction. The present invention also provides conductive clothes showing surface electroconductivety overall in clothes and capable of diffusing static electricity rapidly into air, by sewing the fabric.
[0008]According to aspects of the present invention, it is possible to obtain a fabric exhibiting excellent surface conductive performance in the whole direction, and to obtain conductive clothes with high surface electroconductive property in clothes overall.

Problems solved by technology

However, in this method, surface electric resistance in the outer surface of clothes is high, and efficiency of diffusing static electricity generated inside the clothes into the outside of the clothes becomes bad.
That means, to enhance the electroconductive property, a blending ratio of conductive yarn must be increased, and an increase in cost accompanied with this cannot be avoided.
Japanese Patent No. 3880743 describes that electroconductive property with the conductive yarn of the other direction is improved by covering nonconductive yarn with conductive yarn, but there remains a problem on processing cost of covering yarn as well.

example 1

[0059]Using two-ply yarn of polyester melt adhesive fiber (84 decitex, 36 filaments) as a warp forming base weave and polyester false twist yarn (334 decitex, 96 filament) as a weft, and as a warp conductive yarn and a weft conductive yarn, a conductive yarn (84 decitex, 9 filaments) composed of surface exposing type yarn shown in FIG. 2 was used. The weave was made as shown in FIG. 1 in such manner that base weave was plain fabric (one-sided mat), and the warp conductive yarns were disposed by dobby weave in a ratio of every 24 yarns of base warps (pitch 5 mm) in skipping over 2 yarns in the obverse side, and one yarn in the reverse side. The weave was made as shown in FIG. 1 in such manner that the weft conductive yarns were inserted in a ratio of every 11 yarns of base wefts in weft double weave (pitch 5 mm), and disposed on the base weft (namely being float yarn) in skipping over 3 yarns in the obverse side, and one yarn in the reverse side. In this way, a gray fabric of 141 yar...

example 2

[0060]It was carried out in the same conditions as Example 1 except that only conductive yarn was changed. Namely, as the conductive yarn, there was used a double twisted yarn (89 decitex, 18 filaments) of polyester false twist yarn (33 decitex, 12 filaments) with surface exposing type conductive yarn (56 decitex, 6 filaments). The fabric obtained was sewn by a sewing machine, and the surface electric resistance of sewn part was measured. Various data are shown in Table 1.

example 3

[0061]Using two-ply yarn of polyester false twist yarn (84 decitex, 36 filaments) as a warp forming base weave and polyester false twist yarn (334 decitex, 96 filaments) as a weft, and as a warp conductive yarn and a weft conductive yarn, a surface exposing type conductive yarn (84 decitex, 9 filaments) was used. The weave was made in such manner that base weave was plain fabric (one-sided mat), and the warp conductive yarns were disposed by dobby weave in a ratio of every 32 yarns of base warps (pitch 5 mm) in skipping over 3 yarns in the obverse side, and one yarn in the reverse side. The weave was made in such manner that the weft conductive yarns were inserted in a ratio of every 15 yarns of base wefts in weft double weave (pitch 5 mm), and disposed on the base weft in skipping over 6 yarns in the obverse side, and 2 yarns in the reverse side. In this way, a gray fabric of 202 yarns / 2.54 cm in warp density and 74 yarns / 2.54 cm in weft density was produced. This gray fabric was r...

Abstract

A fabric comprises conductive yarns inserted each in a warp direction and a weft direction and disposed in a lattice at intervals, wherein at least either one of the conductive yarns in the warp direction or the weft direction is inserted as a double weave to be a float yarn on the surface that the conductive yarn becomes a float yarn in the double weave, wherein a ratio of the conductive yarn inserted as the double weave not covered by an orthogonal nonconductive yarn but exposed is not less than 50% in arithmetic average, and a ratio of the conductive yarns in the warp direction and the weft direction intersect and contact each other is not less than 40% in arithmetic average. Clothes comprise the fabric, wherein the conductive yarn is inserted as the double weave in an obverse side of the clothes.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a U.S. National Phase Application of PCT International Application No. PCT / JP2008 / 073597, filed Dec. 25, 2008, which claims priority to Japanese Patent Application No. 2008-004052, filed Jan. 11, 2008, the contents of these applications being incorporated by reference herein in their entirety.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates to a fabric having excellent surface electroconductive and antistatic properties, and to clothes that the fabric is sewn.
