摘　　要：The compact spinning with pneumatic groove utilizes transverse air force and mechanical force of the pneumatic groove to condense fiber bundles to eliminate the spinning triangle.Range analysis and variance analysis of orthogonal experiment were used to discover both important and general factors that influence the condensing effect of the compact yarn including negative pressure,traveler,roving moisture regain,and spinning tension.Results from this research have confirmed that the spinning tension is the most important factor affecting the condensing effect and the yarn quality;the negative pressure,traveler,and roving moisture regain are general factors.The optimal combination for producing least yarn hairiness,A3B2C1D1,is acquired,where the value of negative pressure A is -3.0 kPa,roving moisture regain B is 7.64%,traveler C is 20 #(yarn tex 20.8),and spinning tension D is 25 cN.The compact spinning with pneumatic groove utilizes transverse air force and mechanical force of the pneumatic groove to condense fiber bundles to eliminate the spinning triangle.
