Composite nonwovens manufacturing technologies

The uses of spunbonded fabrics as coverstock in diapers and other personal absorbent devices will most likely remain unchallenged for the near term. Virtually any other nonwoven production method appears to be at a cost disadvantage opposite spunbonded polypropylene. There have been composite products developed from meltblown and spunbonded combinations, where areas of either improved hydrophobicity or hydrophilicity are desired. These products can be produced on-line at relatively low additional cost and offer high value to diaper manufacturers. Any competitive threat is likely to come from advances in film technology such as large improvements in perforated film used in segments of absorbent product appHcations, particularly sanitary napkins. 

The RKW Group is a leading international manufacturer of high-quality plastic films and nonwovens. CaPlast are another leading specialist. Their wide web technology allows the creation on nonwoven composites with up to five layers. Applications include construction membranes, pipeliners (CIPP) and automotive.
