On-line and off-line measurements were obtained to gain an understanding of fly production during multi-hole melt blowing at commercial speed. These measurements allowed us to describe the effects of common processing parameters on fly production and develop a model for fly formation that begins to account for experimental measurements.

The Relationship

Melt blowing is an important process for producing nanofibrous nonwovens. Compared to another technology for producing nanofibrous nonwovens, electrospinning, melt blowing applies high-speed air flow field to attenuate the extruded polymer jet. In this study, the air flow field of a swirl die melt-blowing process was simulated by CFD software, Fluent 6.3. The swirling air profile was shown. Meanwhile, a high-speed camera was used to capture the fiber path below a single-orifice melt-blowing swirl die. The spiral motion of the fiber was revealed. The relationship between the fiber path and the air flow field was discussed. This paper shows the relationship between the fiber path and the air flow field in a swirl die melt-blowing process.

We conducted numerous experiments to achieve greater understanding of multi-hole melt blowing at commercial speed. On-line measurements acquired near the collector and off-line measurements of web structure allowed us to better understand fiber speed, fiber flow direction, fiber orientation and fiber entanglement during melt blowing.

The Web

A probabilistic modeling approach has been proposed to correlate motion of a filament to the web structural formation in single filament melt blowing. By treating fiber motion as a Markov process, a probabilistic space has been determined where fiber has a greatest chance of being present in the web structure and in its flight to the collection system. Based on the positional probabilities, a single fiber's motion space has been determined to be correlated to its diameter. Experimental data show that any process or material variable that leads to a variation in fiber diameter affects the lateral spread of fiber motion, and thereby web structure formation in a single filament melt blowing process.
