Title:
WOVEN FABRIC FOR SHIELDING ELECTROMAGNETIC WAVE
Document Type and Number:
Japanese Patent JP10046443
Kind Code:
A
Abstract:

To obtain a flexible woven fabric suitable for clothes for protecting the damages of human bodies with electric magnetic waves, capable of being post-dyed (dyed in a fabric state), and capable of being maintained in the effective electromagnetic wave-shielding property also after repeatedly washed.

This electromagnetic wave-shielding woven fabric having a shielding effect of ≥26 decibel in an electromagnetic field having a frequency of 300 mega Hertz and a shielding effect of ≥30 decibel in an electromagnetic field having a frequency of 1 giga Hertz is produced by arranging silver-plated conductive nylon 66 fibers having a shrinkage rate of ≤3 percent in 130°C hot water in a woven fabric comprising an arbitrary fiber raw material and having an arbitrary woven tissue, an arbitrary woven density and an arbitrary METSUKE and subsequently dyeing the fabric (post-dyeing) by a conventional method for the arbitrary fiber raw material. The flexural rigidities (gram ×square centimeter/centimeter) of the electromagnetic wave-shielding woven fabric in the warp direction and in the weft direction do not exceed 150 percent of those of the same woven fabric not containing the conductive fibers and produced only from the arbitrary fiber raw material.
