Abstract: This paper mainly devoted to the weaving principle and design of the annular shaped fabrics.The let-off and take-up mechanisms of the weaving machine were modified.The creel let-off mechanism could meet the requirement of unequal warp yarn length of this fabric.The round table shaped roller was able to control the taking-up of the formed cloth in the loom,as well as the shape and structure of the fabric.The weft yarns went in the direction of the generatrix of the round table shaped roller and the warp ends along its circumference.There were two types of design of annular shaped fabrics: with uneven filling density and with even filling density.The weaving of the fabrics with uneven filling density was simple but it had unevenly distributed structure.Weaving the fabric with even filling density required rather complex shedding mechanism.Its filling yarns were divided into the long picks and the short ones,the former interlaced with all warp yarns,whereas the latter interlaced with only part of the warp yarns.The pick repeat in a complete weave,as well as the distribution of the short picks among the long ones,should be properly designed so as to obtain an even fabric structure.
