Abstract: In this paper, a new kind of Hollow Roller Compact spinning system with strip groove structure-Complete condensing Spinning was presented. The structure composition of the spinning system and spun yarn qualities were introduced in detail. Finally, the spinning experiments in Complete condensing Spinning and lattice apron compact spinning systems were given, and corresponding spun yarn qualities were measured. It is shown that comparing with spun yarn in lattice apron compact spinning system, the spun yarn in Complete condensing Spinning system has a little better evenness, less hairiness above 3mm, more hairiness below 2mm, and slightly poor yarn strength. Meanwhile, the Complete condensing Spinning system has less operation and maintenance cost, and lower energy consumption. Therefore, the Complete condensing Spinning system presented in this paper will have good marketing value.

Key words: hollow roller, compact spinning system, complete condensing spinning, yarn quality
