Production technology and quality control for PAN bulky top

Xie Qun (Acrylic Fiber Plant of Qilu Petrochemical Co. , Zibo 255040)  
The influential factors on the quality of dry-spun PAN bukly tops, such as length, steam shrinkage, yarn irregularity, were analyzed. The results showed that the PAN bulky top with high quality can be produced under the conditions as followed: draw ratio of 4.95 on the stretcher, the first distance of rebreaking zone 105 mm, the second distance of rebreaking zone 125 mm, hot draw ratio 1.32, electric heat plate temperature 180℃, the mass ratio of high-shrinkage top and regular top 40:60, draw ratio of 7. 389 and 8. 6 on mixing gill and balling gill, respectively.
