Emery cloth backing


In technical textiles rotor-spun yarns are used preferably for emery cloth backing and generally for coating substrates. Especially high standards of yarn regularity, yarn purity and yarn tenacity are imposed on these fabrics. Rotor-spun yarns are predestined for use in these fabrics by virtue of their small mass variations. The fact that rotorspun yarns are knot-free is especially advantageous. Knots are disturbing defects in these fabrics. The required high tenacity of 18 - 20 cN/tex is achieved by using polyester fibers instead of cotton.
