ABSTRACT

Over five hundreds of mono- and bi-component meltblown web samples have been produced on 24-inch wide Reicofil® side-by-side bicomponent meltblown line since its installation at TANDEC in March 1999 using various thermoplastic resins such as polypropylene (PP), polyethylene (PE), poly[ethylene terephthalate] (PET), poly[butylenes terephthalate] (PBT), polyamide (PA), and their bicomponent (bico) pairs, such as PP/PE, PP/PET, PE/PET, PP/PA, PBT/PE and PBT/PP. Several dietip geometries of different air gap/setback were applied. In this research, three dietip geometries of air gap/setback as 0.5mm/0.7mm, 0.8mm/1.0mm, 2.0mm/2.0mm are compared based on available data obtained with similar processing conditions, resultant web structure and properties.
