Dyeing Properties

In this study, a mixed bi-functional reactive dye was applied to the cotton and hemp woven fabrics. Their dyeing and fastness properties were compared. From the results, it was observed that the cotton fabric exhibits better exhaustion and levelness than hemp woven fabrics. The build-up and fastness properties of the two woven fabrics appeared to be almost similar.

The Relationship

In order to determine the relationship between the fiber properties of the yarn quality in the article, experiments were conducted using a passive method of mathematical planning and a regression equation was obtained for each optimal parameter. Based on the experiments, it was found that a decrease in fiber micronaire, an increase in tensile strength, fiber length and uniformity, leads to an increase in the specific tensile strength of yarn, a decrease in the coefficient of variation in tensile strength and the number of breaks in the yarn.

Impurities And Defects

The quality of the produced yarn mainly depends on the properties of the raw material, its preparation for spinning, the condition of the equipment, and the preservation of the natural quality of cotton fiber during processing. The question of the number of defects in cotton fiber and their total content is a very important issue for cotton spinning. The non-standardized number of defects in the raw material reduces the quality indicators and yarn yield, which requires additional technological processes; therefore, on the part of production, the requirements for reducing the share of cotton fiber defects are constantly increasing. During processing in blowing and cleaning units and on carding machines, the cotton fiber is mechanically damaged. To observation the damaged fibers, we used the Congo-Roth red paint according to the method of Ch. Dore. Despite the carding is considered the last stage in the process of cleaning the fibers from impurities and defects in the spinning system, 30% of impurities and fiber defects still remain on the card sliver. Besides, it should be noted the carding machine is also considered an additional occurrence of defects, in particular (neps), which reduce the quality indicators of the card sliver and the finished product.

This article examines the influence of the parameters of the coating teeth of the discrete drum on the quality of the OE yarn. Based on the analysis of the conditions for retention of fibers by the covering teeth of the discrete drum, equations were obtained to determine the angle of inclination of the teeth. To determine the effect of the coating parameters of the discrete drum teeth on yarn quality, experiments were performed using the Full Factor Experiments mathematical planning method, and a regression equation was obtained for each variable. As a result, the optimal values of the discretization drum coating teeth of the OE spinning machine were determined.

The article describes research studies in the laboratories of the departments of "Spinning Technology" and "Silk Technology". For this purpose were taken samples of cotton fiber and silk waste from the carding machine in the spinning process, 100% cotton fiber waste, 50% cotton fiber, 30% silk, 20% mulberry bark fiber, 70% cotton fiber, 15% silk, 15% mulberry bark fiber, non-woven fabrics were produced from 75% cotton fiber 10% silk 15% mulberry bark fiber blends. The single-period elongation deformation of the obtained non-woven fabrics was determined using the device "Stoyka".

Yarn Production

This study was mainly focused on the optimization of spacer size and degree of shore hardness in ring frame drafting systems to improve yarn quality parameters. The 100% cotton fiber carded yarn samples of 35.5Nm were produced to analyze the effect of spacer size and degree of shore hardness with different combinations. The spacers were 4.2 and 4.5 mm and the shore hardness was 70 back & 62 front and 70 back & 65 front. All yarn samples of the same count were produced on the same spinning positions by changing the spacer’s size and degree of shore hardness by keeping all other parameters constant. The produced samples were tested according to standard testing methods and instruments. After testing, the tested results were compared to analyze the influence of spacer size and shore hardness on yarn quality in a ring spinning frame. The technologist needs to understand this and act on it to optimize the yarn production. The specific size of the spacer with specific shore hardness should be used for a particular count of yarn. The results showed that yarn quality i.e. U%, Cvm, Neps +200%/km, Thick +50%/km, Thin -50%/ km, TIPI are considerably influenced by the spacer size with different shore hardness. So it is concluded that the best result has been obtained in the case of using a pink color spacer (4.2mm) with 70 degrees back and 65 front degree front top rollers.
