ABSTRACT

The purpose of this research comparison property fiber processed in various cotton primary processing factories with different models of gins. Each sample of 1st grade С6524 of cotton raw has been subdivided to process factory gins of Namangan area. Properties of the Fiber of all samples have been measured with the Advanced Information System of Fiber HVI, for definition of an exit of average length fiber UHM (UHML).

Introduction

Globally, cotton fibers for sale are selected and measured in accordance with (HVI) standards. Fiber standards (HVI) are set by ‘SIFAT’ enterprise to define fiber properties such as color, length, micronaire, strength, and trash content that are important in textile processing. Fiber quality is an important aspect of cotton research and the fiber must be removed from the seed to determine its bulkiness.

The purpose of our study was to compare the quality of the fiber and to analyze the cotton factories of the Namangan region with different types of gins and their working parts that contribute to the yield of medium fiber length. Hereby, to determine the optimal parameters of the working parts of the gin for modeling the quality of the fiber. The fundamental basis for our research was a study conducted by American scientists, in regard to a comparing factory and laboratory gins, since the differences between laboratory gins and production gins have not been studied. Thus, their research has shown that the results obtained from the gins of the laboratory cannot be accurately reproduced, even with a correction factor, while in the production of gins in cotton processing plants [1], [2].  But correlation analysis indicated that factory-adjusted experimental new gin survived produced lint samples that were most similar to production lint samples, considering all properties. These results demonstrate that factory-adjusted experimental laboratory gins offer an effective, convenient screening tool for cotton researchers predicting fiber quality in production gins [1], [2].   

Methods

Hence, using these data, we have determined the way of conducting the research. To begin with, we have carried out a statistical analysis, having received data from the ‘SIFAT’ enterprise for cotton fiber of the first grade C6524 of the harvest of first year of research, second year of research, third year of research, hence the main indicator we have taken was the average yield of the long fiber. It is marked as UHM (UHML) - the upper as well as average fiber length, which characterizes by the average length of half, approximately 50% by the weight of the longer fibers in the measured sample, determines the type of cotton fiber, and inch. [3-6]. 

Results

We took the statistical results of 10 textile clusters per yield of average fiber length

Table 1.

Figure 1. Statistical data factories of the first year of the research on the quality of cotton fiber С6524 the first grade

A statistical analysis of the first year illustrated that the graph showed that the highest UHM (UHML) is the upper average fiber length at the Mirishkor cotton factory and it is composed of 1.136 inches from 50% in relation to the cotton weight.

And the lowest UHM (UHML) - the upper average fiber length at the Kasan cotton factory consists of 1.118 inches from 50% in relation to the cotton weight accordingly.

A statistical analysis of the second year demonstrated that the graph showed that the highest UHM (UHML) is the upper average fiber length at the Mirishkor cotton plant and it is composed of 1.134 inches from 50% in relation to the cotton weight. And the lowest UHM (UHML) - the upper average fiber length is at the Kasan cotton mill and it is comprised of 1.117 inches from 50% in relation to the cotton weight respectively.

Table 3.

Statistical data of the third year of the research on the quality of cotton fiber С6524 the first grade

Figure 3. Statistical data of the third year of the research on the quality of cotton fiber С6524 the first grade

A statistical analysis of the third year indicated that this graph showed that the highest UHM (UHML) is the upper average fiber length at the Mirishkor cotton factory and is comprised of 1.128 inches from 50% in relation to the cotton weight. And the lowest UHM (UHML) - the upper average fiber length at Uychi cotton mill consists of 1.124 inches from 50% in relation to the cotton weight accordingly.  [7-10]. 

Conclusion. The results acquired from the production gins of cotton factories showed that the highest UHM (UHML) is the upper average fiber length at the Mirishkor cotton factory and is 1.132 inches from 50% based on the cotton weight in which ‘Lummus’ brand saw gins are utilized. The second place is taken by the cotton factory of Namangan, hence the average value over three years is UHM (UHML) and 1.128 inches from 50% in relation to the weight of the cotton, in which saw gins of 4DP-130 are used accordingly. Thus, the study along with a statistical analysis shows that it is crucial to determine the factors, which cause an increment in the yield of the average fiber length. And, to determine and invent a new experimental gin sample structure for increasing the yield of long fiber fractions and ameliorating the average fiber length, it is substantial to investigate the working parts of the saw gin at the cotton factories of Mirishkor, Tashbulak and Namangan .
