Study on the process parameters 0f the rotor spun yarn using gene expression programming.

Abstract

The report details the steps for execution, findings, and recommendations of the project fore- mentioned. The project used GEP to probe the number of yarn imperfections present in a polyester/cotton (65:35) blend. Yarn twist and rotor speed were used as input parameters for the model. Uster 3 was used to measure the number of yarn imperfections which is the output for the model. Yarns were produced from a series of experiments carried out at Southern Range Nyanza Limited (S) in Jinja, Uganda. Sliver of count O.015Ne was used to produce the yarns Tests were carried out on the samples to obtain relevant data. The data obtained was then used to build a GEP model that was tested and validated. The model had an R-square of 0.97, RM E,44.5 which meant, the model was a good approximate of number of yam imperfections. The developed model was used to study the relationship between the inputs and the output and conclusion, recommendation made.
