The Tutorial

In fact melt blown nonwovens technology is very simple The polymer melt extruded by screw extruder is blown by high-speed hot air to make the melt flow be extremely stretched to form microfiber These microfiber condenses on the screen or roller to form the fiber net and then becomes nonwovens by self adhesion The technological process is: PP material feeding → melt extrusion → fiber

PLA and PP Composite Nonwoven with Antimicrobial

The composite nonwovens were obtained using the melt-blown technique which is an integrated nonwoven technology which consists in linking the fibre-forming process with web-forming process The strings of molten polymer come out of the extruder head through the multihole nozzle where they are blown up by the stream of hot compressed air and set as fine fibres on a collecting drum (Figure 1 )

Melt Blown Fabrics for Chemical Protective Liners

Novel melt blown fabrics were processed from thermoplastic polyurethanes (TPU) using both a 6-inch and a 20-inch melt blowing () line at the University of Tennessee's Textile and Nonwovens Development Center (TANDEC) These nonwovens were developed to determine the processing conditions to produce the finest fiber and most uniform nonwoven fabrics possible with TPUs to be

China Continuous Screen Changer Melt Filter for Non

In nonwovens manufacture it is necessary to achieve a uniform spinning quality across all spin packs Therefore any in homogeneities must be removed before they enter the spinning beam Moreover process consistency regarding pressure and temperature is the basic prerequisite for an efficient production Our GM-DP-R series double-piston continuous screen changer is widely used on spun

Nonwovens manufacturing process

Nonwovens manufacturing usually includes webformation and web-consolidation Nonwovens are either referred to by the webformation technology or by the consolidation technology used Webformation technologies include drylaid carded drylaid high-loft airlaid wetlaid spunlaid meltblown (the combination of spunlaid and meltblown is sometimes referred to as spunmelt) and various ways of

melt gear pump for melt blown fabric

The polymer masterbatch is put into the extruder and melted in the extruder at a temperature of about 240 ℃ (for the main resin used in PP melt blown method) The melt flows through the metering pump to the melt blown die head The metering pump measures the melt flow output to the nozzle The spinneret is a capillary tube with a spacing of less than 1mm and a diameter of 0 2-0 4mm

Melt Blown Fabric Making Machine

Melt blown lines The continuous fibres produced by the single row melt blown process have a diameter below one micrometer This makes them suitable for the production of highly demanding HEPA filters with H12 filtration efficiency Filaments from single row melt blown are stretched across the die width at precise temperature The uniform

Meltblown

The melt supplied to the spinnerets is produced by an extruder that heats and melts thermoplastic pellets to a viscosity that will allow them to flow through the spinnerets The picture shows the fibers being blown out of the spinnerets and collected on a rotating drum The drum is porous and has a vacuum inside that causes the fibers to cling to the surface of the drum As the drum revolves
