Method for making meltblown fiber spools
Meltblown nonwovens are made by extruding molten polymer through fine nozzles, forming ultra-fine fibers collected into a fabric web. Polypropylene is the most common polymer used, with melt temperature, air velocity, and die-to-collector distance critically affecting fiber. If you want to produce high-quality meltblown nonwoven fabrics, you'll focus on melting polymers like polypropylene, then extruding them through fine nozzles in a specialized die head. The randomly deposited fibers form a nonwoven sheet product applicable for filtration, sorbents, apparels and drug delivery. Is a modified form of melt spinning, in which the drafting air is replaced with warm cooling action. This air flow causes the fibers to remain in a molten state for a longer. Melt blowing is a process for producing fibrous webs or articles directly from polymers or resins using high-velocity air or another appropriate force to attenuate the filaments. The melt-blown process is one of the newer and least developed nonwoven processes.
