The hydro treating effect on the elastic properties of previously fixed cotton-lycra blended fabric

The article materials are devoted to the hydro treating effects research, such as scouring and dyeing, on the elastic properties of the previously single jersey for a certain period of time and at the different temperatures by comparing the force necessary to lengthen the fabric by 80% of the original length and width after the process of fixing, scouring and dyeing in light, gray and dark. Thermal fixation affects the fabric physical properties, increasing the force required for a certain elongation of the fabric in the longitudinal and transverse directions, especially in the transverse direction (weft) due to the large influence of flexibility, since it is directly affected by this process when the fixation temperature increases. In addition, other processes following the hydro treating, for example, dyeing, reduce efforts, and dyeing in gray and dark colors is more effective, since it contains washing phase after dyeing at the high temperatures to remove any traces of non-fixed dye on the fabric.
