The spin Guard Gardella is a centrifugal type dry spinning machine. In this machine yarn can be spun from 72 (2.08 lbs./spy) to 241 tex (7 lbs./spy). But in this system of this machine, it is preferable to produce fine yarn. Here fine yarn 103 tex (3 lbs./spy) was produced in existing speed. Apron Draft Spinning frame was modified into ring spinning system. In this system rings and travelers were used and fine yarn upto 103 tex (3 lbs./spy) was produced. Bangla white B (BWB) grade jute fibres were used for producing fine yarn. The spinning performance and physical properties of produced yarn were found and compared. It was found that the yarn produced from Gardella spinning frame was better than modified ring spinning frame.
An emulsion making process has been developed for spinning hessian type jute yarn by eliminating mineral oil from the normal sequence of emulsion processing. A number of experiments were carried out with jute fibers and 242 and 280 tex yarn were spun on the hessian spinning frame. It was observed that the elimination of mineral oil in emulsion processing did not make the yarn quality worse.
