To loosen the fiber 3 To convert the rooty material into spinnable fiber Required time of pilling: Jute Spinning Carding: Carding is a combining operation where jute reeds are spitted and extraneous matters are removed Jute fibers are formed into ribbon called "sliver" Breaker Carding : In different jute mills the carding operations has been carried out in two ways: a Hand feed breaker carding b Rool... machine makes more uniform sliver and reduce the jute into a suitable size for third drawing Jute Spinning Third Drawing: In the third drawing, the Third Drawing frame machine uses the sliver from second drawing The Third Drawing machine is of high speed makes the sliver more crimpled and suitable for spinning The comparison of the three drawing process: Drawing Process (%) Productivity Mt/mc/shift Ist Drawing... 1.31 - 1.4 Winding Winding Winding is a process which provides yarn as spools and cops for the requirement of beaming and weaving operations There are two types of winding : (i) Spool Winding (ii) and Cope Winding Spoll Winding: In Spool Winding yarn is produces for warp Spool winding machine consists of a number of spindles .The Spool are used in making sheets of yarn to form warp portion used during... sheets of yarn to form warp portion used during interlacement of weaving Cop Winding: Cop Winding machine obtain yarns from the spinning machines The spinning bobbins are placed on a suitable pin on top of the cop machine and yarn tension is maintained by means of a small leaver Jute Spinning Jute Spinning ... rollers, staves, pinning arrangement and speed Nearly 4 to 12 slivers obtained from Breaker carding machine is fed on this machine The material thus obtained is send to drawing section Jute Spinning Drawing: Drawing is a process for reducing sliver width and thickness by simultaneously mixing 4 to 6 sliver together There are three types of Drawing Frame machine First Drawing: The first drawing frame machines .
