Have you ever seen a situation where the air flow from an air pump can blow a strand of wool into fluffy tufts? The basic principle of polyester air change yarn is similar, but it is much more refined and professional. To put it simply, by leveraging the high energy of compressed air, the smooth surface of the originally slippery polypropylene long filament is blown into a series of fluffy hairs and small loop-like attachments, making it feel more fluffy and closer to the texture of cotton yarn. 

The processing of polyester air change yarn essentially can be regarded as a physical modification of polypropylene long filaments through the use of high-pressure air flow. This process does not rely on chemical reagents but utilizes the principles of aerodynamics to give the originally smooth and flat filaments a fluffy and curly appearance and a texture similar to short fiber yarn. 

During the operation, the polypropylene raw filament is sent into a specially designed nozzle device. Inside the nozzle, high-pressure compressed air forms a chaotic airflow field. This airflow has a high speed and high energy and acts on the polypropylene filament bundle, forcing the individual filaments to shift, causing surface bulges, or generating local loops and arcs. At the same time, due to the good thermoplastic property of polypropylene, with the assistance of the heat generated by the airflow friction, the loops and hair-like fibers on the filament surface will obtain temporary stabilization. 

Subsequently, the air-flow modified filament bundle passes through a stable area (such as a cooling or setting zone), where the previously temporarily set ring structure is completely fixed. The final output of the polypropylene hollow filament presents a state with a surface covered by tiny filament loops and a significant increase in loftiness. This structure mimics the surface features of natural fibers or cotton-type short-fiber yarns, but still retains the low density, quick drying, and corrosion resistance characteristics of polypropylene. 

From an application perspective, the air-deformed polypropylene yarn is suitable for weaving fabrics with the appearance of cotton or jute. It does not require the multiple processes of traditional spinning. Instead, it can be transformed directly from long filaments into yarn with a short-fiber-like texture in just one step. Throughout the entire process, factors such as air pressure, nozzle structure, and the feeding speed of the filament are the key control points. By adjusting these parameters, one can obtain air-deformed yarn products with different levels of loft and pile density.
