Original Study


In this work the dynamic stability of the mechanical vibrations of the sewing needle during sewing process under the impact of the time dependent penetration force (cyclic type) were studied. The many mathematical equations were written and explained for both of the sewing needle dynamics and penetration force mechanics. They were related to the regions of sewing needle stability regions either mathematically or graphically. Mate equation (difficult one) was refereed to help in investigation the sewing dynamic stability during sewing process.
