Discussion on several ways to improve quality of knotless yarn

To increase the splicing strength of knotless yarn,reduce its surface hairiness and improve the winding forming of the bobbin,a further analysis is made of the bobbin technology and technique to provide an effective way of improving the knotless yarn quality.The analysis has shown that reasonably choosing types and installation site of splicer,adopting new bobbin technique including using devices of reducing hairiness and intelligent winding bobbin,rationally determining the speed of cone winder and the technical parameters of bobbin tension can increase the strength of knotless yarn,decrease the unevenness of its strength,reduce the surface hairiness,assure the good forming of bobbin and adapt to high speed unwinding,thus improving the weavability of the knotless yarn.
