Improvement wool dying processes

Abstract

It is known that the dyeing process used in laboratory conditions does not allow taking into account the influence of such parameters as the flow rate of the dye solution, the density when placing the dyed fibers, etc. In this regard, the article considers the use of a plant for dyeing textile materials, including dyeing fibers weighing 1-10 grams. In this regard, the article considers the use of a plant for dyeing textile materials, including dyeing fibers weighing 1-10 grams. The influence of the speed of movement of the dyeing system in the range of 1.1 to 1.8 m/min and the weight of the fiber in the dyeing volume in the range of 27.7-125 kg/m3 on the absorption of dyes from the dye bath was studied. When changing the speed of the flow of the dyeing system in the range of 1.1-1.43 m/min, an increase in the content of the dye on the fiber and an increase in the brightness of the color in the range of 37.5-48.9 are observed. It should be noted that with an increase in the flow rate of the dyeing system over 1.43 m/min, the amount of dye on the fiber decreases the brightness to 41.6. This can be judged from the results of measuring the brightness of the color and the coefficient of unevenness, which amounted to 11.24%. The use of the considered installation for dyeing textile materials in the conditions of dyeing shops of the finishing production of the textile industry will allow you to quickly introduce new dyeing recipes and significantly reduce the time for their practical implementation.
