Bicomponent Meltblown Nonwovens and Fibre Splitting

Side-by-side bicomponent meltblown fibre webs are produced on Reicofil® bicomponent (bico) meltblown line at TANDEC using polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyamide (PA), polytrimethylene terephthalate (PTT), polylactide (PLA), etc. In this study, fibre splitting of the bico meltblown webs is investigated by several approaches, including hydroentanglement, hot water treatment, benzoic acid treatment, and alkali treatment. The web properties and the interfacial adhesion within the bico fibre are also discussed.
