The modernization of open end spinning frame for producing high elasticity core yarn

The plan of modernization of open end spinning frame for producing combined highelasticity yarns was developed. At the RUE “BSCE” enterprise the modernization of serial open end spinning frame PPM-120-AM was made. The optimization of thechnological process was carried out and the optimal parameters of twist and elastomer thread draft were defined. The experimental variants of yarns were produced, which were processed later in assortment of cloth.
