1 The melt-blown layer looks very different from the other two transparent non-woven layers it looks more like a white paper 2 Different from a paper the melt-blown layer melts in case of fire but does not flame with very low flammability Instead paper burns when it comes to fire 3 There is static electricity in the melt-blown layer

Tessuto non tessuto

Tessuto non tessuto (TNT) il termine generico per indicare un prodotto industriale simile a un tessuto ma ottenuto con procedimenti diversi dalla tessitura (incrocio di fili di trama e di ordito tramite telaio) e dalla maglieria Pertanto in un non tessuto le fibre presentano un andamento casuale senza individuazione di alcuna struttura ordinata mentre in un tessuto le fibre presentano

FaceMaskFAQ

According to Wikipedia melt-blown nonwovens are produced by extruding melted polymer fibers through a spin net or dye consisting of up to 40 holes per inch to form long thin fibers which are stretched and cooled by passing hot air over the fibers as they fall from the dye The resultant web is collected into rolls and subsequently converted to finished products The extremely fine fibers

Melt blowing technology

Melt blowing is a process for manufacture of nonwoven fabric in which thermoplastic polymer is extruded from a die tip having a row of spinneret orifices with typically 25-35 holes/inch The fibers exiting from the die tip are contacted with converging sheets or jets of hot air to stretch or draw the fibers down to a ultra-fine diameters typically ranging between 2-4 μm The fibers are then
