NSC Nonwoven is introducing T.T Excelle card. Before this innovation, for the inline carding process, as production lines increased their linear speed, it was common to see a progressive drop in the physical strength properties of the final wipe fabric. This loss of strength always comes with a more unbalanced MD/CD strength ratio and consequently quality properties become very limited when wipes are produced at high speed.
The wipe market application requirements, and the development of high speed converting equipment, with more demanding physical properties, means requests from the roll good producers for a minimum CD value which are out of reach when running at speeds more than 170-200 m/min. The few high speed lines which are running faster are dedicated to niche markets where wipe fabrics accept MD/CD values in excess of 5:1 and CD strength values well under 20 N/5 cm.
