CLOVERDALE, CA, July 16, 2014-

Reifenhäuser and ExxonMobil have worked together to come up with an answer to a challenge faced by an increasing number of nonwovens producers who have been working at the margins of low weight spunbond fabrics.

Polypropylene polymer is conventionally used to produce nonwovens for a wide range of disposable and durable products. The polymer is an industry workhorse due to its combination of good processing, spun fiber properties, worldwide availability and relatively low cost. Disposable hygiene product components from polypropylene spunbond and meltblown nonwovens have evolved over time into lower denier and basis weight materials primarily to reduce cost. Nonwoven suppliers, however, are increasingly challenged to make high quality nonwovens at a high rate of production with fine denier and low weight without trading off either spinnability or fabric tensile strength and softness. Fabrics produced with a denier below 2.0 can have lower tenacity or filament spinnability issues may arise such as breaks and spinline drips.
