MONITORING DATA

Imperfections IPI

(Option)

The classical yarn clearing in the winding process is design-
ed for the recording of thick/thin places in the yarn which are
defined according to the respective fault classes.

In yarn fault classification, seldom and frequent yarn faults
are distinguished. The general rule is that the shorter the fault
length or the smaller the diameter variation, the more fre-
quent the events. In textile usage, frequent yarn faults are
also referred to as Imperfections.

The raw material, card wires, eccentric top rollers/bottom roll-
ers, defective aprons, rings and ring travelers etc. have a sig-
nificant influences on the Imperfections.

The recording of the Imperfections must be considered as de-
tailed online quality control in the winding process.

IPI Diameter

Diameter-related Imperfections: In addition to the frequent
yarn faults (Neps, Thicks, Thins), YarnMaster Zenit also clas-
sifies the so-called very fre quent events (Small), the “small”
Imperfections. These small Imperfections are used to evalu-
ate the evenness of the checked yarn.

IPI Length

Length-related Imperfections: In addition to the diameter-
related Imperfections, length-related Imperfections (from
2–4 cm, 4–8 cm, 8–20 cm and 20–70 cm) are also classified.
