Melt Blown Non Woven Die
The meltblown nonwoven process is using high-speed hot air to draw the melt stream from spinneret hole of die. After this process,microfiber will be formed and gathered on the collecting screen or roller.At last the meltblown nonwoven fabric is formed by the self-bonding microfiber. The die acts a very important role in this process,especially for fabric's thickness uniformity.So it requires high-precision manufacturing for die.
Technical Advantages
· The most optimized coat-hanger flow channel will be design,according to polymers'different characteristics,including viscosity,processing temperature and flow velocity,thus make melt distribution more uniform.
1.Roughness of mold cavity is at 0.01um－0.03um
2.The special heating device is with high efficiency of heating and heat exchanging, while with low energy consumption.
3.Special air chute structure makes air pressure stable and air flow of both sides symmetrical.
4.Width of air gap can be adjusted easily and real-timely.
