Process difference between PET/PLA and PP in non woven fabric machines

“The basic process of in non woven fabric machine is different when using different polymer raw materials”, said an engineer from AZX Nonwoven Machine with 10 years of experience in the installation and commissioning of PET, PLA, and PP non woven fabric machines.

1. Process flow when using PP raw materials in non woven fabric machine
Conveying → metering and mixing → melt extrusion → filtration → metering → spinneret extrusion → cooling → drafting → web forming → fiber web consolidation → winding and slitting → non-woven fabric products.

2. Process flow when using PET/PLA raw materials in non woven fabric machine
Conveying → drying → metering and mixing → melt extrusion → filtration → metering → spinneret extrusion → cooling → drafting → web forming → fiber web consolidation → (setting) → winding and slitting → non-woven fabric products.

From the above process flow, it can be seen that the production process of PET/PLA nonwoven fabric is basically the same as that of PP raw materials, except that a drying process of raw materials is added, and some production lines may also add a thermal “setting” process.

AZX Nonwoven Machine has rich experience in the production of PET/PLA and PP nonwoven fabric, and we will update more consultation on the nonwoven machinery industry in the future.
