“…The lower the quality of cotton fibers results in lower quality of yarn produced. Cotton is the main natural fibre, which presents a large variation in its properties (Price et al, 2009;Majumdar and Majumdar, 2004). Physical properties of cotton affect the production efficiency and yarn quality.…”

“…Particularly in the polymer and textile processing industry, airflows have also been playing important roles in various processing methods such as melt‐blowing [6], air‐jet weft insertion, and vortex spinning. Vortex spinning has been accepted as one of the most promising technological innovations due to its advantages in processing speed and cost [7, 8]. For the prevailing Murata vortex spinning (MVS) system, the resultant yarn is twisted by the airflow inside a spinning nozzle [9, 10].…”

A numerical model is presented to simulate the fiber motion in the airflow inside the vortex spinning nozzle (VSN). The coupling between the fiber and airflow together with the fiber‐wall contact is solved. Based on the numerical model, the motional characteristics of four types of fibers—cotton, viscose rayon, lyocell, and polyester fibers—in the airflow inside the vortex spinning nozzle are simulated and analyzed. The vortex yarn structure is viewed under the scanning electron microscope and the fiber strength utilization factors of the vortex yarns spun from different types of fibers are compared to verify the wrapping effects of different types of fibers in the vortex yarns obtained by the numerical simulation. The agreement between the numerical and experimental results shows that the numerical modeling methodology proposed in this research provides a reliable way of investigating the fiber dynamics in airflow and an efficient solution to the mechanical problems in polymer/textile manufacturing processes involving fluid–solid coupling.

“…The formed yarn is then delivered out of the nozzle through the yarn passage of the hollow spindle with the drag of the delivery rollers and fed to the winding part. The most featuring characteristic of the vortex spinning is that it is capable of spinning 100% cotton fibers at very high speed (450m/min) and the produced yarn has a structure much similar to the ring spun yarn [2]. Some researchers have pointed out that the dynamic behavior of the fiber in the airflow field inside the nozzle plays an important role in the twist insertion process of vortex spinning [4][5].…”

Vortex spinning, which adopts high speed airflow to insert twist into the yarn, is one of the most promising technological innovations in the textile industry. In vortex spinning, the dynamic behavior of the fiber inside the nozzle, which involves fiber-airflow interaction and fiber-wall contact, plays an important role in the twist insertion process. This paper investigates the airflow characteristics and the fiber dynamic behavior inside the vortex spinning nozzle via a two-dimensional numerical model with the fiber-airflow interaction and fiber-wall contact included. The fiber is assumed to be isotropic, elastic material. The airflow inside the nozzle is assumed to be turbulent, viscous and incompressible. The numerical results show that two vortices with momentarily changed sizes are created upstream of the jet orifice outlets. The imbalance of the pressure around the fiber causes the fiber to move and deform. The trailing end of the fiber rotates with wave shape within the nozzle chamber for several periods to insert twist into the yarn. Based on the model, the effects of three nozzle structure parameters-the jet orifice angle, jet orifice diameter, distance between the nozzle inlet and the hollow spindle, on the dynamic behavior of the fiber, and in turn, the yarn structure and tensile property are investigated. The results show that the appropriate jet orifice angle for obtaining the best yarn tenacity is 70°. The optimal jet orifice diameter is 0.4 mm. The spun yarn has the highest tenacity when the distance between the nozzle inlet and the hollow spindle is 14 mm.
