New Ciba Polymer Modifier Suitable For Nonwovens

Ciba Specialty Chemicals, Switzerland, recently introduced Ciba® IRGATEC® CR 76, a polymer modifier that enables nonwoven fabrics producers to design meltblown nonwoven fabrics with improved mechanical and liquid barrier properties using polypropylene spunbond grades or recycled granules from fiber scrap.

The modifier controls molecular weight degradation during spinning by lowering melt viscosity; and narrows molecular weight distribution, resulting in enhanced spinnability and fabric performance, according to the company.

"[IRGATEC CR 76] will provide new opportunities for the producers of meltblown, spunbond/meltblown/spunbond composites and spunbond nonwoven fabrics to develop products and applications that the currently available technology does not allow," said Jean-Roch Pauquet, head of industry textiles and carpets in Ciba Specialty Chemicals plastic additives segment.
