In order to study the effect of guide roller motion state in sizing machine drying room on pure cotton yarn hairiness,by controlling guide rollers that merge the pre-dried yarns from the sizing machine,tests were conducted on the total number of hairiness,number of harmful hairiness,hairiness H value and hairiness S value of 9.7 tex,14.6 tex and 18.2 tex pure cotton compacted yarns under both driven and fixed guide roller conditions.The effect of sizing concentration,sizing speed and sizing pressure on the sized yarn hairiness were investigated when the guide roller was in fixed position.The results showed that for yarns with different counts,the reduction to sizing hairiness was greater when the guide roller was fixed rather than driven.Compared to the guide roller in driven state,the number of harmful hairiness reduction rate was reached approximately 32.06％when the guide roller was in fixed position.Different sizing process parameters all affected yarn hairiness when the guide roller was in fixed position,the effect level of sizing concentration was the greatest,the next was sizing pressure,while the sizing speed was the least.It is considered that sizing hairiness could be reduced effectively when the guide roller is in fixed position and appropriate sizing process are adopted.The method was simple and effective,which has better practical value.
