Abstract
An industrial two-layer fabric includes an upper surface side fabric constituted by upper surface side warps and upper surface side wefts, one a lower surface side fabric constituted by lower surface side warps and lower surface side wefts, the upper surface side warps include a warp binding yarn, wherein two adjacent upper surface side warps that includes a upper surface side warp that weaves only the upper surface side wefts and the warp binding yarn form a pair, the warp binding yarn of the pair passes below three of the adjacent upper surface side wefts where the warp binding yarn passes below the one of the lower surface side wefts, a ratio of the number of the upper surface side warps to the number of the lower surface side is 2:1.
Claims8
An industrial two-layer fabric comprising, in a complete structure:
- an upper surface side fabric constituted by upper surface side warps and upper surface side wefts,
- a lower surface side fabric constituted by lower surface side warps and lower surface side wefts, wherein:
- the upper surface side warps comprise a first pair that consists of two of the adjacent upper surface side warps,
- a first upper surface side warp of the first pair passes above and below the upper surface side wefts only,
- a second upper surface side warp of the first pair is a warp binding yarn that passes above one of the upper surface side wefts and passes below one of the lower surface side wefts,
- the second upper surface side warp passes below at least three of the adjacent upper surface side wefts where the second upper surface side warp passes below the one of the lower surface side wefts,
- a ratio of a number of the upper surface side warps to a number of the lower surface side warps is 2:1.
