Abstract
A seamless double-woven fabric for filling down includes a first fabric layer including first warps and first wefts, a second fabric layer including second warps and second wefts, and a coupling part to partition a down filling part formed between the first and second fabric layers into down filling spaces. The first warp and the second warp are formed so as to be crossed to each other one time or at least two times through a coupling weft. If the number of the coupling wefts is 2 n, wherein n is an integer of 1 or more, the first and second fabric layers are arranged to be crossed about the coupling part. If the number of the coupling wefts is 2 n+1, wherein n is an integer of 0 or more, the first and second fabric layers are arranged not to be crossed.
