Problem addressed
Nu-Torque™ cotton yarns have good soft handle and surface appearance, higher yarn tenacity at lower twist levels, lower residual torque and hairiness, and low knitted fabric spirality after washing. They can provide much thinner and lighter fabrics as well as unique wool like softness of fabric. However, the current technology is difficult to manufacture finer yarn counts, even at 30Ne.
Innovation
- Enhancement of yarn counts to the target of 30Ne and 40Ne by optimising spinning processing
- Optimisation of processing parameters for weaving and circular knitting, fabric assessment
- Optimisation of yarn dyeing and fabric dyeing procedure and parameters
Key impact
- Yarn production cost: 24-40% increase in productivity because of lower twist level at the same yarn strength; 10% saving as no yarn plying is needed.
- Energy saving: saving around 337 units (kilowatt hours) of electricity per one ton of yarn produced.
