Industrial Attachment: Spinning process
Fiber
• Fibre purchasing system
• Types of fibre used in spinning mill
• Mostly used fibre in spg mill( if possible collect percentage)
• fibre price (according to fibre types)
• Last two years fibre price
• Per consignment no of bales
• per bale wt
• Fibre storage capacity according to mill
• How many no. of bales are stored all time in the mill.
• What process is done when bale is kept in the store?
• Spinning limit
