The Institute of Textiles & Clothing of the Hong Kong Polytechnic University has developed a technique to produce Nu-Torque singles ring yarns for weaving in a single step on a modified ring spinning frame. The surface appearance of denim fabric and fabric dimensional stability after laundering is improved by the application of Nu-Torque singles ring yarns on woven fabrics. Yarn structure can be improved and yarn residual torque can be reduced significantly with an attachment installed on the conventional ring spinning frame. During an experiment, a fabric sample was produced by using the Nu-Torque yarns as weft yarns, to evaluate the effects of weft yarn torque on the 'small snake' pattern of denim fabrics. Two conventional fabrics with normal and low twist level yarns were also woven for comparison of fabric properties and appearance. The effects of yarn torque on dimensional stability of fabrics in plain, hopsack, and satin weave structures were also studied. The results show that the evenness of Nu-Torque yarn is similar to that of conventional yarns, while yarn hairiness of Nu-Torque yarns is less than that of conventional yarns.
