In the cotton spinning process, the performance and effect of a rotary type ring has been compared with those of a conventional type ring. Rotor Spin Ring, the rotary ring developed by our research laboratory, has been put to practical use. Further, dynamic properties of the rotary ring are analyzed theoretically.
The cotton spinning tests show that in using the rotary ring the abrasion of travellers decreases and the yarn quality is roughly equal in comparison with the conventional, but other effects are not confirmed.
A theoretical calculation has shown that the consumption of the electric power in the spinning process with the rotary rings is identical with that of the conventional, if the spinning tension of both types of rings is equal. In practical spinning process, however, the spinning tension of the rotary ring is higher than that of a conventional ring even if travellers of the same count are used. Thus, the rotary rings increase the consumption of electric power.
In conclusions the rotary ring gives littel effect on the cotton spinning process.
