spun bond non woven

Spun bond non woven technology is one of the main process methods in the production of non-woven fabrics, and it is also the fastest-growing non-woven technology with the highest technical content. This article briefly introduces the spinning process in the spun bond non woven production process. The spinning process used in the production of spun bond non woven is basically the same as that of synthetic fibers. The process includes slice feeding, drying, screw extruder melting, filtering, metering and spinning. The drying process depends on whether the processed slices contain moisture. Drying is not required when processing PP chips, and drying equipment is required for processing PET chips. However, according to reports, the Kobe Steel twin-screw extruder does not need to dry PET chips.
