The working process of spunbond nonwoven fabrics
CL Nonwoven
We build spunbond, meltblown, spunmelt composite nonwoven production lines since 1992.
As you can see in the picture,there are three floors in the?spunbond nonwoven production line.
The first(top) floor is formed of feeding system,including suction,dosing and mixing device,the PP granule is suctioned from the ground.Then the extruder will melt the PP granule into PP melt and transfer it to the filter.After filter is the metering pump.The metering pump can control the speed of melt flow to the spinning box.
On the second floor,the material will become PP filaments in the spinning box and coming down to the diffuser.In the diffuser we use the high speed wind to cool down filaments and draw them into a thinner fiber by one suction fan and one blowing fan.From the stretching to diffuser, the fibers will be collected by the web former on ground floor.The web former can transfer the fiber to the calender.After the embossing by calendar,we wind the final nonwoven fabric.
