It is important that pirns are wound properly for effective outcomes. And, equally important is their winding efficiency. There are various factors that determine the winding efficiency of pirns, some of which are stated here.
E N D
Pirns are rods onto which weft thread is wound for usage in weaving. They are long rods made of wood or plastic, tapering for most of its length, and flaring out more sharply at the base. They are similar to bobbins, only with the difference that pirns are tapered, and that they are not wound evenly from end to end as in the case of bobbins. They are wound completely on one portion of the pirn, and then moving on to another portion. For the best quality pirns, you can get in touch with Trim Engineering Services, the leading pirn manufacturers in India since the past 30 years! Just like it is important that bobbins are wound tight and in position, it is equally important for pirns to be wound properly too. Winding efficiency of a pirn is also important. Winding efficiency is the ratio of actual production and calculated production, and is expressed as percentage. This makes the formula as – Winding efficiency = (Actual production / Calculated production) x 100 {Here, calculated production is always higher than the actual production.} There are various factors that determine the winding efficiency of pirns, some of which are stated here. Yarn quality
Yarn quality is directly proportional to winding efficiency, which means that if the yarn quality increases, the winding efficiency will also increase. Yarn count Yarn count is directly proportional to winding efficiency. Thus, if the yarn count is higher, then the winding efficiency will also be higher. Maintenance and over hauling If the maintenance and over hauling of the winding machine is not perfect, the winding efficiency will be decreased. Work load per worker Work load per worker is inversely proportional to winding efficiency. Therefore, if the work load per worker increases, the winding efficiency is decreased. Capacity utilization Capacity utilization is inversely proportional to winding efficiency, meaning that if the utilization of capacity is increased, the winding efficiency will be decreased. Worker efficiency Worker efficiency is directly proportional to winding efficiency. This means that if the worker efficiency increases, the winding efficiency also increases. Drum speed Drum speed is directly proportional to winding efficiency, which means that if drum speed is more, then the winding efficiency will also be increased. Power failure Power failure is inversely proportional to winding efficiency. Thus, if the power failure increases, the winding efficiency will decrease. Humidity Humidity could be directly or inversely proportional to winding efficiency depending upon the type of yarn. In the case of cotton yarn, humidity is directly proportional to winding efficiency; while in the case of other yarns, humidity is inversely proportional to winding efficiency. This means that if humidity increases, the winding efficiency of cotton yarns increases, while that of other yarns decreases.
Creeling time Creeling time is inversely proportional to winding efficiency, meaning that if creeling time is more, the winding efficiency will be less. Doffing time Doffing time is inversely proportional to winding efficiency, indicating that if doffing time is more, the winding efficiency will be less.
