I am working with a polyester POY production company. I am a chemical engineer and I have a very little knowledge about spinning. I want to know whether % Uster plays any role in estimating the theoretical throughput measurement of the Spinning. I know only following formula for calculating theoretical throughput of free-fall yarn of a spinning position (assuming 100% machine efficiency)

(POY Denior)*(No of ends/Position)*(Spinning Speed)*(1-OPU)*60*24 / (9000*1000)

Here OPU means Oil Pick-Up

We dont have any reliable method of estimating throughput per day of our POY spinning plant.We have a computerized system which gives certain data but somehow it is also not working well. Can somebody suggest any method by which we can do this.

Thanks

Vishal,

The formula used above is quite regularly used for spinning throughput. I don't know what other method you are looking for. What you can do is check with your Bobbin packing section and ask them to provide you a daily packed production report. Based on this you can formulate your own spinning machine efficiency factor. Alternatively you can discuss this with the takeup/winder supplier (Barmag/Toray/Chinese) and ask them for the machine efficiency data. If you have Barmag/Toray winders you are sure to get reliable data, can't say the same about chinese copycats.

Hope this helps.
