摘要:
Method and apparatus for reducing residual torque in singles ring yarns, achieved by imparting two separate false twisting points on the traveling strand of fibers (or yarn) after the strand exits from the spinning triangle with a proper ratio between the belt speed and the strand feeding speed. In addition to reducing the residual torque, this double false twist technique also reduces yarn hairiness to the same level as achieved by more expensive compact spinning devices, reduces yarn twist by more than 20% and significantly enhances yarn and fabric softness. Furthermore, by combining the double false twist technique with a compact spinning device, the numbers of neps, thick and thin places are significantly reduced to produce high-quality yarns and fine-count yarns.

摘要:
A process for measuring snarling properties of a yarn is provided. Firstly a first and a second point of the yarn are held in close proximity, and a portion of the yarn between the two points is of a predetermined length. A predetermined tension force is temporarily exerted to the portion of the yarn, and simultaneously the portion of the yarn is temporarily restricted from twisting when the tension force is exerted. Then the portion of the yarn is released from the tension force such that the portion of the yarn is able to twist freely so as to form snarls thereon. Thereafter, the snarling properties of the yarn are measured by detecting an amount of the snarls thereby formed.
