Nonwoven fabrics have become increasingly popular in recent years due to their flexibility and versatility in various applications. Among these is meltblown nonwoven fabric, which is considered the most critical layer in face masks and other respiratory protective equipment (RPE). To manufacture such high-efficiency filtration materials, companies like Hollingsworth & Vose are at the forefront of developing cutting-edge solutions that meet complex technical specifications.
Hollingsworth & Vose (H&V) is a world-renowned manufacturing company, founded in 1843 and headquartered in East Walpole, Massachusetts. H&V is committed to producing high-performance materials for advanced applications such as industrial, transportation, and health care. The company has operations in Asia, Europe, and the Americas, serving customers in more than 80 countries. H&V's innovation and leadership in filtration technology have made it the go-to manufacturer for meltblown nonwoven fabric.
What is Meltblown Nonwoven Fabric?
Meltblown nonwoven fabric is a nonwoven material made from polypropylene (PP) resin. It is used to produce various products, including surgical masks, N95 respirators, and other air filtration devices. Meltblown technology is unique and innovative as it involves a highly controlled process for producing ultra-fine fibers through extrusion and hot air flow that creates a random network of fibers. This process results in a thin web-like material with a high surface area, making it highly effective in trapping particles and droplets in the air.
Meltblown Nonwoven Fabric Manufacturing Process
The manufacturing of meltblown nonwoven fabric involves several steps, beginning with the production of the PP resin molecules. The resin particles are then melted into a liquid state and extruded through a spinneret (a small orifice with many holes). The hot air blows the jets of liquid to create ultrafine fibers that form a random network. The fabric is then subjected to several post-treatment processes such as static discharge, curving, and calendaring to produce the desired properties.
H&V's Contribution to Meltblown Nonwoven Fabric Manufacturing
