Acrylic Fiber Spinning with a Rotary Ring

This paper describes the results of the investigation of the possibility of high-speed and stable acrylic spinning with rotary rings. Results of the test are as follows:(1) The wear of travellers on the rotary ring is far less than that on the stationary ring.(2) At high-speed (15, 500rpm), yarn fluffs caused by the rotary ring are significantly less than those by the stationary ring.(3) Strength and elongation of single yarns produced by the rotary ring are superior to those by the stationary ring under certain spinning conditions (at 15, 500rpm and at the start of the spinning). But no significant difference is found under other conditions.(4) At high-speed rotating, melt yarn by the rotary ring is less than that by the stationary ring.(5) Yarn end-down and traveller fly-away with the rotary ring are significantly lower than those with the stationary ring.(6) The power consumption by the rotary ring does not differ from that by the stationary ring. From the above results, it is concluded that the rotaty ring is effective for high-speed spinning of acrylic yarns.
