Air textured yarn, also known as jet textured yarn, is a new type of textile yarn. The morphological structure of air spun yarn includes surface structure and yarn core structure. Air textured yarn is applied in various fields of the textile industry. Air textured yarn is a new type of textile yarn. The long filaments in air spun yarn are densely arranged and intertwined, resulting in a compact yarn structure. The various sizes of silk loops and arcs randomly distributed on the surface of the yarn give the air spun yarn a similar appearance to short fiber yarn, namely short fiber yarn

Performance

Strength and elongation performance

The tensile curves of short fiber yarn, air change yarn, and their feed into the raw silk show significant differences among the three curves.

. Short fiber yarn, air change yarn, and their feeding raw silk are made of polyester fibers with the same linear density. Usually, the strength of unmodified yarn is higher than that of hollow yarn and short fiber yarn. However, air deformation processing does not cause any damage to the inpidual filaments themselves. After deformation processing, the decrease in yarn strength is the result of the formation of silk loops and entanglement between inpidual fibers

Instability

When a certain load is applied to the air spun yarn, some of the silk circles and arcs on the surface of the yarn will be pulled away, and the number of remaining silk circles depends on the stability of the silk circles.

. The stability of the silk loop is determined by the deformation effect, which means it is not only related to the material type of the feeding yarn, the linear density of the single filament, the number of single filaments, and the cross-sectional shape of the single filament, but also to processing parameters such as nozzle type, gas supply pressure, deformation speed, and overfeeding rate

Application

The application range and end use of air spun yarns are usually determined by their structure and performance.

. Due to the versatility of the air texturing process and its yarns mentioned earlier, air texturing yarns can be applied in various fields of the textile industry

Nylon air change yarn suitable for woven fabrics

Nylon air change yarn used for making ski clothes is the first market for air change yarn used as woven weft yarn.

. Due to the adhesion of adjacent yarn surface loops to each other, it is difficult to unwind and cannot be used as warp yarn without sizing or twisting. Now, these limitations no longer exist, such as using fine denier silk or combining different filaments, which can solve the above problems

Polyester air change yarn suitable for automotive products

In terms of automotive interior, the seat cover, seat backrest, inner door panel, and inner roof panel can all be made of polyester air change yarn.

. Car seats are often subjected to heat, strong sunlight, and extensive wear and tear. Polyester air textured yarn can meet the above requirements Polypropylene air textured yarns suitable for decorative fabrics are mostly made using the spinning drafting process as decorative materials, so there is no need for further drafting before deformation processing. Multiple yarns can be placed on the creel simultaneously, such as 5 or 6 single yarns, so it is necessary to install a single yarn breakage or defect detection device. The feed yarn is usually melt dyed yarn Polypropylene air spun yarn used for decorative fabrics has a single filament density of 4.4-6.7 dtex. Due to the high overfeeding rate of leather yarn, the phenomenon of brushing or hooking is prone to occur. Therefore, it is advisable to use conical drums for winding Polyester air spun yarn suitable for sewing thread
