Finer Nu-Torque Cotton Yarn Production

Since 2002, The Hong Kong Polytechnic University (HK PolyU) has developed a novel ring spinning technology, namely Nu-Torque yarn technology, for the production of torque free singles ring yarns by a single step on a ring spinning machine. The study has demonstrated that Nu-Torque cotton yarns and fabrics have significant advantages in terms of yarn and fabric properties such as soft handle and improved fabric surface appearance, higher yarn tenacity at lower twist levels, lower residual torque and lower hairiness, and yarn novel effects, in addition to low knitted fabric spirality after washing. In the finer cotton yarn sector, there are a number of additional advantages. With the singles yarns, the technology can provide much thinner and lighter fabrics produced by the finer yarns whose linear densities are reduced by half. With unique wool like softness of fabric made from Nu-Torque cotton yarns, this technology will help cotton to be better applied and to compete with fibers like wool and other man-made fibers in the areas of shirts, polo shirts, pants and sweaters. However, the current technology is difficult to manufacture finer yarn counts, even at 30Ne. Thus the proposed project is intended to further develop the technology for mass production of finer Nu-Torque cotton yarns for weaving and knitting. The target yarn counts are 30Ne and 40Ne.
