EFFECT OF TWIST ON PRODUCTIVITY OF FINE JUTE YARN PRODUCED BY MODIFIED RING SPINNING MACHINE (Pages : 14 - 16)
M. OSMAN GHANI MIAZI, A.K.M. MAHABUBUZZAMAN, MOHAMMAD MANIRUZZAMAN MOHAMMAD ABDUL JALIL AND M. ABDUS SHAHIDThis research was done in Mechanical Processing Division of Bangladesh Jute Research Institute in 2008. An Apron Draft spinning machine was modified into ring system by incorporating rings and travelers instead of flyers. In this modification, delivery zone of the machine was left unchanged. Two rails were incorporated, one for carrying spindle and another one for carrying rings. An idle roller was installed at the rear end of the machine for transferring power from main roller to the spindles. The input sliver of the machine was varied from 2412 tex to 2756 tex (70 to 80 lbs/spy). Twists of the yarn were inserted from 236 to 394 tpm (turns per meter). A good number of trail runs were performed for determining the productivity and quality of yarn produced by the machine at different twists. Productivity of yarn of 103 tex and 138 tex through the machine were observed at different twists. It was observed that twists have an important influence on the productivity and quality of yarn.Download
