Raw polymer pellets are precisely metered and fed into an extruder, where they are melted and homogenized. A precision melt pump then steadily pumps the melt through a filtration unit to remove impurities. Finally, the melt is evenly distributed across the entire spinneret via a temperature-controlled manifold called the spinning beam.

The nascent polymer streams exiting the spinneret first enter a quench chamber, where they are rapidly solidified into solid filaments by controlled cooling air. The filament bundles are immediately drawn into a high-speed air aspirator. Here, supersonic air flow applies a drafting force, stretching the filaments at tremendous speed. This drastically reduces their diameter and increases molecular orientation, granting them the required fineness and strength.

The high-velocity, attenuated filament bundles enter a wide forming section. First, they pass through a diffuser to decelerate and randomize their movement. With the continuous movement of the forming wire (conveyor belt) below and the assistance of suction units underneath, countless filaments settle like snowflakes, piling up and randomly interlapping to form a uniform, lofty, yet unbonded fiber web.

The loose web is conveyed to the bonding unit. The most common method is thermal calendering: the web passes through a pair of heated, pressurized large rollers (the calender), where one roller features a precise pattern (e.g., dots, diamonds) on its surface. The combined action of heat and pressure causes the fibers to fuse at the pattern's contact points, creating a strong yet soft fabric structure.

The bonded fabric may undergo edge trimming and slitting to achieve the standard roll width. It is then wound at high speed into neat jumbo rolls by a fully automatic winder. The entire process is typically equipped with an online quality monitoring system to inspect and record fabric uniformity, defects, and other metrics in real time.
