Winding Efficiency : The ratio of actual production and calculated production is called winding efficiency. It is expressed as percentage. The efficiency of a highly automated winding operation is calculated by modification of the mathematical model developed for a similar problem.
Winding efficiency depends on the following factors
- Spindle or drum speed: the higher the speed the more is the winding efficiency
- Yarn Count: yarn count is proportional to winding efficiency
- Yarn quality: if yarn quality increases then winding efficiency increases
- Worker efficiency: the more efficient the work is the more efficient the winding will be.
- Humidity: humidity is reciprocal or inversely proportional to winding efficiency.
- Work load per worker: If the work load on each worker is less then efficiency of winding will be more.
- Maintenance and over hauling: if the maintenance and over hauling of the machine is not correct then efficiency of winding will decrease.
- Power failure: if power failure rate increases the winding efficiency will decrease.
- Creeling time: the more the creeling time the less is the efficiency.
- Doffing time: the more the doffing time the less is the efficiency.
- Capacity utilization: when capacity utilization decreases then efficiency increases.
Reasons for lower efficiency
- power failure
- improper maintenance and over hauling
- natural disasters
- less skilled labor
- labor unrest
- shortage of machine parts and raw materials
- strike
- maintenance problems
