AB  - The basic intention of the presented research is to analyse the permeability properties of woven fabrics containingtwo-ply   fancy   yarns   in   the   weft   direction.   Within   the   framework   of   presented   research,   two-ply   fancy   yarns   wereanalysed. Because of their structure, they are classified as fancy yarns with structural effects. The first analysed two-plyfancy yarn is made of the mixture of 81% cotton and 19% viscose. The second is made of the mixture of 67% viscoseand 33% flax. For the purpose of the presented research, woven fabrics containing two-ply fancy yarn were made inthree different densities in weft (10 threads per cm, 13 threads per cm, and 16 threads per cm) in the twill weave T 1/3 Z.The theoretical part includes the historical development of the production of the fancy yarns, a detailed discussion of thering production processes, the types and the structure of the fancy yarns, their use, and the global and European marketof the fancy yarns. The experimental part consists of three parts. In the first part, the structural properties of the analysedfancy yarns were researched (the fineness of the fancy yarn, the frequency of repeating the effects per one meter of theyarn, the direction of twisting the fancy yarn, the number of the twists of the basic and the effective part, the diameter ofthe fibers, the diameter of the basic and the effective part, the fineness of individual components, the direction of thetwist of individual components, and the percentage of the inside twist of individual components). In the second part,constructional   properties   of   the   analysed   woven   fabrics   with   the   fancy   yarn   in   the   weft   were   researched   (mass,thickness,   the   density   of   the   warp   and   weft   threads,   and   openness   of   the   surface).   In   the   third   part,   permeabilityproperties of the analysed woven fabrics with the fancy yarn in the weft were researched where greater attention waspaid to air permeability and water vapour permeability. The results of the research showed that the samples with the firsttwo-ply   fancy   yarn   in   the   weft   (81%   cotton   and   19%   viscose)   have   greater   air   permeability   and   water   vapourpermeability. Meanwhile, the samples with the second two-ply fancy yarn in the weft (67% viscose and 33% flax) havelesser abrasion resistance and poorer dimensional stability while being washed.
