Abstract

The research was based on studying the effect of the speed for terry fabric production machines on the stability of the pile and the air permeability of towel fabrics. The specifications of the warp used were constant in (number - material - density) with the change in the tension applied to the pile warp and its amount as follows (55CN - 60 CN - 65CN). The ground warp was constant at 145 CN, and the density of the wefts was changed and three different densities were used, namely (18 p/cm - 21 p/cm - 24 p/cm). The third is the speed of the machine. Three different speeds of the machine were applied, which are (200 rpm - 250 rpm - 300 rpm). The study concluded that the difference in machine speed has an impact on the amount of pile stability . The highest rates of pile stability are always achieved with samples produced with the machine with the highest speed (300 rpm). The lowest rates of pile stability are also achieved with samples produced with the machine at the lowest speed (200 rpm), . The speed of the machine also has an impact on the air permeability rates of samples, as the highest rates of air permeability are always achieved in samples produced with the machine with the lowest speed (200 rpm), and the lowest rates of air permeability are achieved in samples produced with the machine with the highest speed (300 rpm) with The remaining variables are constant
