Document Type and Number:
WIPO Patent Application WO/2022/215289
Kind Code:
A1
Abstract:
[Problem] To provide an antistatic warp knitted fabric that has antistatic properties in all directions from among the warp direction, the weft direction, and the bias direction of a knitted fabric, that is capable of effectively maintaining said antistatic properties in all directions even after repeated wearing and washing, and that makes it possible to obtain work clothing provided with both stretchability and favorable feeling of wear. [Solution] A warp knitted fabric which is formed from (a) a composite yarn including a conductive yarn and a first non-conductive yarn, and (b) a second non-conductive yarn, and which is characterized in that: (1) the composite yarn includes a yarn that constitutes at least one of the front surface and/or rear surface of the warp knitted fabric; (2) the composite yarn has one or more stitches formed by loops of adjacent composite yarns being overlapped with one another; (3) the variation value (MMD) in surface friction in the weft direction of the warp knitted fabric is 0.01-0.10; and (4) the surface resistance value in the warp direction, the weft direction, and the bias direction after ten washes, measured according to IEC 61340-5-1, is 1.0×1010Ω or less in each direction.
