Conclusions

The effect of polymer melt temperature fluctuation at the inlet to the metering pump on nonuniformity in yarn linear density has been studied.

It has been shown that considerable fluctuation in yarn linear density, caused by change in melt temperature, takes place also in individual working sites.

A considerable difference in the temperature of the melt going to individual working sites of machines for spinning technical yarns has been discovered.

Fluctuation in the linear density of yarn caused by variation in melt temperature at the inlet to the metering pump may reach 0.3–0.8% in spinning technical yarns, depending on the construction (group or individual) of the spinning machine melting devices.
