| COMPANY ADVANTAGE |
|
Meltblowing is a unique one-step process for producing self-bonded fibrous nonwoven membranes directly from polymer resins, with average fiber diameter ranging between 1 and 2 mm. Determining routes for making nano- or submicron-fibers using this process are desirable since there are many manufacturing assets that are already in place. It is envisaged that these nonwoven membranes will find applications in critical areas such as medical, hygiene, filtration, bioseparation, and others.
One critical area of application for meltblown webs is in the area of aerosol filtration. The advantages of small fibers for filtration are well documented. Meltblowing has the potential to compete favorably with electrospinning if the meltblowing process could be used to produce materials in the nanofiber range; meltblowing would provide a much faster, easier, and less costly alternative to the electrospinning technique. It is not surprising that meltblowing has prompted a significant amount of activity in the literature. Investigators have studied the process from different perspectives. Several studies have focused on characterizing the process–structure–property relationships by using techniques such as laser doppler velocimetry and high speed imaging and computational fluid dynamics. Shambaugh et al. studied the effect of the slot die geometry on the air flow field below the MB die and its effect on the fiber size. The effect of the nose-piece shape on the flow field under the MB die was investigated experimentally by Tate and Shambaugh and theoretically by using CFD simulations by Krutka and Shambaugh [24–26]. Tate et al. showed experimentally that using a blunt MB die produces a lower maximum centerline velocity and that the centerline velocity profile decays at a higher rate than that observed using a sharp MB die. Higher maximum centerline air velocity in the z-direction is favorable as it leads to an increased rate of fiber attenuation (i.e., finer fiber) for a given air flow rate. Milligan and Wadsworth made use of a cross-flow to obtain finer fiber diameter and improve the uniformity of the produced fiber mats. Lee and Wadsworth studied the effect of meltblowing process condition such as air temperature, die to collector distance, and air flow rate on filtration properties of meltblown polypropylene webs. They found that pore size and air permeability decreased with increasing processing temperature, increasing air flow rate at the die, or decreasing die-to-collector distance.
