Polypropylene air change yarn, with its advantages of good fluffiness and soft hand feel, is widely used in the textile and fiber field and is an important raw material for home textiles, decorative fabrics, industrial fabrics and other products. Hongyang Chemical Fiber, which focuses on the production of chemical fibers, has accumulated rich experience in the manufacturing of polypropylene aerated filament. Although its production process is clear, the precise control of each link has become the key to ensuring product quality.

In the production process of polypropylene air change yarn of Hongyang Chemical Fiber, raw material preparation is the primary step. Enterprises usually choose polypropylene chips with a high melt index. These chips need to undergo professional drying treatment first to completely remove internal moisture - this step can effectively prevent the formation of bubbles during subsequent spinning and ensure the stability of filament quality. The dried slices are fed into the screw extruder and melted into a uniform melt at the preset temperature. After the melt is filtered for impurities by the spinning component, it is precisely ejected from the spinneret to form the initial primary fibers.

The cavitation treatment is the core process in the molding of polypropylene cavitation filament, and Hongyang Chemical Fiber has strict parameter control in this process. The nascent fibers are first rapidly shaped through a cooling device and then introduced into an air conditioning nozzle. Under the action of high-pressure compressed air, the filaments will naturally form irregular, fluffy, twisted and intertwined structures, eventually presenting the unique form of polypropylene air change yarns. Hongyang Chemical Fiber will flexibly adjust the air pressure and filament speed according to the different product requirements, which not only avoids filament breakage due to excessive pressure but also prevents insufficient pressure from affecting the fluffiness.

The filaments after cavitation still need to go through the drawing process. Through the stretching effect of the drawing machine, Hongyang Chemical Fiber further enhances the strength and elasticity of the fibers, while consolidating the stability of the cavitation structure. Finally, after being wound into a cylinder in an orderly manner by a winding machine, the finished polypropylene air change yarn can be obtained. Throughout the entire production process, Hongyang Chemical Fiber conducts real-time monitoring of key parameters such as temperature, speed, and pressure to ensure that the product's breaking strength, fluffiness, and other indicators meet the demands of downstream customers.

With the development of industry technology, Hongyang Chemical Fiber is also promoting the intelligent upgrade of the production process of  polypropylene air change yarn. By introducing an automatic control system, it realizes dynamic parameter adjustment and quality traceability, providing more reliable raw material support for home textiles, industrial fabrics and other fields.
