Down-proof double-layer fabric

摘要

A first fabric layer of a down-proof double-layer fabric has a plurality of first warps and a plurality of first wefts. A second fabric layer has a plurality of second warps and a plurality of second wefts. The first fabric layer and the second fabric layer have a plurality of coupling portions. In the coupling portions, the first fabric layer and the second fabric layer pass through each other repeatedly, and the first warps and the second warps are interlaced. The first warps, the first wefts, the second warps, and the second wefts are between 20 denier and 75 denier. The warp densities of the first fabric layer and the second fabric layer are between 336 pieces/in and 456 pieces/in, and the weft densities of the first fabric layer and the second fabric layer are between 220 pieces/inch2 and 300 pieces/in.
