Jute Spinning:
Jute is one of the cheapest natural fibers. It is long soft, shiny vegetable fiber that can be spun into yarn. Jute yarn manufacturing or jute spinning is a complex process. To produce jute yarn some process are done in jute spinning mill. Raw jute in the form of bales are processed in jute mills to produce Hessian, sacking, jute yarn, bags, and other useful products.

Problem-1:
Find out the production of spreader machine from the following information:
- Dollop weight = 36 lbs,
- Clock length = 6 yds,
- Delivery speed = 60 yds/min,
- M/C draft = 12,
- Emulsion applied = 12%
Delivery speed X Dollop weight
Production per lbs/hour =……………………………………… X Emulsion %
Draft X Clock length
60 X 60 X 36 100 + 12
= ………………….. X …………………
12 X 6 100
= 2016 yds/hr (ANS)
Problem-2:
Calculate production per of jute carding machine from the following data:
- Feed roller speed = 18 ft/min,
- Dollop wt = 30 lbs,
- Clock length = 19.5 yds,
- Waste = 4%,
- Efficiency = 85%
18 30 100-4
Production per hr = ….. X 60 X 0.85 X ……… X ……… lbs/hr
3 19.5 100
= 451.93 lbs/hr (ANS)
