Air texturing uses air to intermingle the individual filaments of a multifilament yarn. The yarn thereby acquires greater volume and stretch, good heat insulation, and high moisture absorption capacity. In addition to this structural change, multiple yarns with different features can also be blended at the same time.

Air-textured high-grade yarns are used for car seats and other upholstery. Glass fibres are used in flame-retardant materials and in products for heat, electrical, and acoustic insulation.

Air-textured yarns has distinctive appearance and physical characteristics of spun yarns.

In intermingling air causes the multiple filaments to be intertwined and mingled with each other to form a compact section. The resulting interlacing knots provide the required yarn compactness. This allows higher processing speeds, resulting in improved package build and a reduced number of filament and yarn breaks during subsequent processes.

In air interlacing, an air blast is used to mechanically intermingle individual yarn filaments together. The resulting interlacing knots provide the required yarn compactness. This allows higher processing speeds, resulting in improved package build and a reduced number of filament and yarn breaks during subsequent processes. The interlaced yarn is superior in post-processing because of cohesion.

With an air migration jet, individual filaments of a yarn are easily intermingled using compressed air without creating interlacing knots. At the same time, the compressed air spreads the unevenly distributed spin finish uniformly within the yarn core. Air migration results in optimal yarn cohesion and yarn runnability, which increases machine efficiency during the spinning process.

During splicing, compressed air is used to interlace the ends of two stationary yarns. The joining thereby achieved has a high level of uniformity and basic strength. Unlike knotted joining, a splice produces fewer problems in subsequent processes because there is less thickening.
