Understanding meltblown and a market gone mad

2020/10/09The production of meltblown in Europe is relatively low. Asia is now the largest producing region, having passed North America in the early 2010s, and now accounts for 45% of the capacity, with China (including Taiwan) accounting for 36% (Figure 2). Get price

Meltblown Technology

The meltblown technology is based on meltblowing process, where, usually, a thermoplastic fiber forming polymer is extruded through a linear die containing several hundred small orifices. Convergent streams of hot air (exiting from the top and bottom sides of the die nosepiece) rapidly attenuate the extruded polymer streams to form extremely fine diameter fibers (1–5 micrometer).

difference between spunbond and meltblown

difference between spunbond and meltblown. Spun-bonded non-woven fabrics are laid after the polymer has been extruded and stretched to form continuous filaments. The filaments are laid into a web, and the web is then subjected to self-adhesion, thermal bonding, chemical bonding, or mechanical reinforcement. The web becomes a non-woven fabric. Get price

Melt blowing

Melt blowing is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas. The randomly deposited fibers form a nonwoven sheet product applicable for filtration, sorbents, apparels and drug delivery systems. Get price
