To eliminate the spinning variations, the roving samples were ring spun into yarns under the same conditions on the same spinning machine. The counts for the yarn samples collected were Nm 14 The yarn samples thus, prepared were tested according to the standard methods as recommended by ASTM Committee b. Yarn twist: The yarn twist was measured using the opposite twist method on the digital twist tester.
Statistical analysis: Linear regression analysis was applied to establish a quantitative relationship between the yarn imperfection neps, thick and thin places with respect to fiber properties, yarn linear density and yarn twist. Meanwhile due to the large number of fiber properties linear relationship between fiber properties and yarn imperfection was assumed. The input parameters for the multiple linear regression models were: fiber properties, yarn twist and yarn count; while the output parameters were number of neps, thick and thin places. The regression analysis expresses the relationship between yarn imperfections and the input variables yarn count, yarn twist and fiber properties.
Table 1 , shows the regression coefficients of each variable. Arrangement of variables in the table indicates their relative importance for the models.
Yarn count, fiber micronaire, fiber strength, fiber elongation and reflectance had a negative influence on the model for the number of neps. The variables that had negative influence on the model are: yarn count, micronaire, fiber length, short fiber index, fiber strength, trash area and yellowness. The factors that had negative influence on the model are: yarn count, micronaire, spinning consistency, fiber strength, trash content, reflectance, trash area and yellowness.
Therefore, the coefficients for the number of neps, thick and thin places indicate that some factors that were consistent in their direction of influence on all the three models for yarn imperfections. Thus, the factors that consistently influenced the yarn imperfections positively were: yarn twist, maturity, uniformity and trash grade. These factors would be considered to have an overall positive influence on yarn imperfections and would increase with an increase in imperfections for in a ring spun yarn.
Meanwhile the factors that had a consistent negative impact on the number of yarn imperfections were: yarn linear density, micronaire and fiber strength. These factors would decrease as the number of imperfections in ring spun yarn increases. Monte Carlo simulation method: The simulation of the multiple linear regression models for the neps, thick and thin place was performed with Monte Carlo techniques, using ModelRisk 3.
The sensitivity analysis graph in Fig. These results are consistent with findings of Kluka et al. It was determined from the sensitivity analysis of the model for number of neps that yarn linear density was had the most influence on the number of neps in ring spinning, this implies that a coarser yarn will have less neps while fine yarns would have more neps.
This agrees with the USTER which established that when fibers of a given number of neps are processed into coarse and fine yarns, the testing equipment will count less neps in the coarse yarn and more neps in fine yarns. Since all deviations are referred to the mean value of the yarn, neps of a given size are less significant in coarse yarns.
Furthermore, Mwasiagi while studying Kenyan cotton also established that the study of the effect of count increased with a decrease in imperfections. The sensitivity analysis also established that fiber micronaire value had significant influence on the number of neps, showing that fibers, which are finer, would be spun into yarns with more neps than those which are coarse.
This is probably due to the fact that fibers with low micronaire have been found to cause excessive nepping during spinning as established by Frydrych et al. The fiber maturity and fiber yellowness in the model also portrayed significant influence on the number of neps in ring spinning which would mean that as the maturity and yellowness of cotton fibers increase yarn neps will increase. This agrees with the findings of Kluka et al. Fiber yellowness is directly linked to the growth environment. Bright creamy-white fibers which have higher reflectance, are more mature.
Premature termination of fiber maturation by application of growth regulators, frost, or drought characteristically increases the saturation of the yellowness. It means that higher yellowness is related to poorer quality and probably the reason behind the positive influence of fiber maturity on the number of neps in ring spun yarn for our model. However, this abnormal behavior of fiber maturity may also be explained from Azzam and Mohamed results, while undertaking a case study of the Egyptian cotton spinning industry they revealed that the main reason for quality problems were unsuitable quality levels, large quality variations and unexplained quality exceptions.
