Drylaid and wetlaid components can be used for the processing of natural fibers and creating new product features for the large biowipes market.
The international technology group Andritz AG, Graz/Austria, offer fully engineered production lines integrating the right equipment for so-called carded-pulp (CP) and carded-pulp-carded (CPC) lines: cost-efficient, flexible, and reliable. These processes combine the benefits of 2 technologies: wetlace and spunlace. The neXline CP is equipped with state-of-the-art stock preparation, including approach flow and fan pump, opening and blending, carding including chute feed, a wetlaid forming unit, hydroentanglement including optional patterning, filtration unit, dewatering, through-air drying and end-of-line equipment. In order to create a 3-layer wipe, an additional card can be added to the carded-pulp process. This opens the door to fiber mixtures with even higher added value and offers high and stable functions while using only biodegradable raw materials. A pulp layer in the middle is surrounded by the carded, e.g. viscose, layers and hence offers additional properties.
