A yarn twisting method and device for a ring spinning machine is provided. The twisting method comprises the following steps: feeding three roving strands () into a back roller () of the ring spinning machine; after drafting, the three roving strands, three fiber strands () exiting from a nip point of a front roller (), wherein a fiber strand () in the middle forms an angle with a plane formed by the other two fiber strands (), and thus the three fiber strands () form a multi-strand spinning triangle region having a three-dimensional spatial form; and in the multi-strand spinning triangle region, the three fiber strands () obtaining twist by means of a ring traveler of the ring spinning machine, and the twisted fiber strands () are combined into a composite yarn () through a convergence point.

Yarn twisting method and device for ring-spinning machine

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.

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.

Yarn snarling testing apparatus and method

In a process for manufacturing a singles ring yarn, firstly a first twist is supplied to a strand of traveling drafted fibers at a false twist device for producing a preliminary singles yarn. The false twist device rotates at a first speed for twisting the fibers. Immediately after the first twisting step, a joint twist of a second twist in the same direction as the first twist and a third twist in a reversed direction is supplied to the preliminary yarn for producing a final singles ring yarn. The second twist is produced by a rotatable take-up package onto which the final singles yarn is drawn. The reversed twist results in correspondence to the first twist, and the take-up package rotates at a second speed. The final singles yarn is then drawn onto the take-up package. Furthermore, a ratio of the first speed to the second speed is controlled for controlling the amount of a residual torque in the final singles ring yarn.

An internal torque balancing method of short fiber yarns related to the art of textile and the manufacturing apparatus thereof. The present invention proposes a completely new mechanical processing method of single torque-free yarns, and applies it into the process of ring spinning. Said method accomplishes a machine and a possibility of processing single torque-free yarns within one processing step by simple improvement on the existing ring spinning machine. Said technique is applicable to the production of all types of short fiber materials, and can overcome the maximum bundle yarn count of Ne limit of the torque-free yarns processed by the existing physical balancing technique. Meanwhile, said technique can process the yarns with low twist, which is unable to be processed normally by the conventional ring spinning machine. The torque-free singles ring spinning machine has good mechanical behavior, good handle, and evenness without residual torque.
