Biovation’s biopolymer meltblown technology extrudes sustainable biopolymers such as Polylactic Acid (PLA) into engineered non-wovens, films, and fabrics. Depending on the end-use requirements, these products can be hydrophilic/absorbent or hydrophobic, can include antimicrobial protection against deadly bacteria, can have an open, porous structure with loft and recovery properties, or can have a smooth, closed-cell surface that can act as a barrier. Materials can be durable and designed to wear well or developed to break down quickly.
In meltblown technology, fibers are formed by extruding a molten thermoplastic material through a die-set as molten threads or filaments into converging high velocity heated gas (e.g., air) streams allowing the filaments of molten thermoplastic material to attenuate their diameter. Consequently, the meltblown fibers are carried by the high velocity gas stream and are deposited on a collecting surface to form a web of randomly dispersed meltblown fibers. Meltblown fibers are microfibers which may be continuous or discontinuous, are generally smaller than about 1.0 denier (1 denier = 1 gram per 9000 meters; a 1 denier fiber has a diameter of about 10 micrometers), and self-bonding when deposited onto a collecting surface.
Melt processes, depending on the control of the process parameters, can be used to make fibers of various dimensions, including macrofibers (with average diameters from about 40 to about 100 microns), textile-type fibers (with average diameters between about 10 and 40 microns), and microfibers (with average diameters less than about 10 microns). This flexibility allows the process to be tuned to specific and unique market applications.
Because Biovation has considerable expertise over the process from raw materials batching through extruding and post-processing, the company can readily adapt its meltblown product expertise to meet your needs.
