“…The surface engineering of nanofibers still remains in an early developmental stage compared to the surface engineering techniques available for conventional fibers such as air‐jet textured yarns . Conventional fibers and their fabrics benefit from various surface engineering tools, allowing for a large diversity of fabric textures.…”

Nanofibers have been developed as basic nanotechnology building blocks, however, unlike with conventional textiles, nanofibers have lacked the surface engineering tools. Herein, we have developed novel basic techniques used to introduce nanoscale bumps and dents on the surfaces of nanofibers. Nanoparticles were first attached uniformly onto nanofibers by electrohydrodynamic jetting, which were subsequently thermally annealed to embed the nanoparticles (bumps). The embedded nanoparticles could be further detached via ultrasonication, resulting in the formation of nanocraters (dents). Ultrasonication could change the contact angle of nanofibers in situ from 848 to 1468. These surface nanoengineering techniques could widen the utility window of nanofibers.

“…Alagirusamy et al [24] reviewed the relationship between air jet, filament yarn and processing parameters to improve the stability of hybrid yarns with highand low-modulus filaments. Mahmood et al [25] described the physical properties of air textured glass yarns to improve the bonding strength of laminated composites according to the linear density of the core and effect, and air pressure. On the other hand, there is no consensus among their findings.…”

This study examined the mechanical properties of a para-aramid filament according to the processing conditions of air-jet textured yarns (ATY). The specimens were prepared by changing the yarn speed, over feed ratio, air pressure, and heater temperature, which are important processing factors in the ATY process. The basic physical properties of the ATY, such as denier, tenacity, breaking strain, and initial modulus, were measured and their thermal shrinkage, such as dry and wet shrinkage, were measured to determine the thermal stability of the aramid ATY. In addition, the instability of para-aramid ATY were measured and assessed with the loop formation of ATY, according to the ATY process parameters. An examination of the effects of process parameters on the physical properties of aramid ATY revealed the core overfeed and air pressure to be the main factors. A high core overfeed and air pressure make the aramid ATY crimpy in the yarn core and entangle the fluffy loops on the yarn surface, resulting in an increase in the yarn linear density and breaking strain as well as a decrease in the tenacity and initial modulus. In contrast, these yarn physical properties were unaffected by the yarn speed, heater temperature, and wetting treatment. In addition, the dry and wet thermal shrinkage were unaffected by the process parameters of ATY. On the other hand, the instability decreased with increasing core overfeed and heater temperature and increased with increasing air pressure. These results showed that a high core overfeed makes the aramid ATY crimpy with an entangled yarn structure, and high air pressure helps provide small loops on the yarn surface. Finally, a high heater temperature makes the crimpy ATY structure more stable due to the strong heat set, which results in low instability.

“…Koc et al (2008) analysed the effect of airtexturing on adhesion behaviour to rubber and concluded that air-jet texturing increase the surface area of the yarn structure and higher adhesion of polyester fabric to rubber could be achieved by air-jet texturing. Research by Mahmood et al (2013aMahmood et al ( , 2013b) used core-effect textured glass yarns for improving the bonding strength of laminated glass woven fabric composites and conclude that the air-jet texturing introduces bulk and loops in the yarn which provides more contact surface between the fibres and the resin.…”

The objective of this research work was to investigate the use of steam as a substitute fluid for air in spun-like textured yarn manufacturing. The new substitute product holds the potential for competitive advantage, lower manufacturing costs and streamlined manufacturing capabilities. Generally high-pressure steam is known to be cheaper to produce than compressed air. An existing air-jet texturing machine was modified to supply either air or steam to the texturing nozzle. Using an identical nozzle, both air-jet and steam-jet textured yarns were manufactured. The influence of effect-yarn parameters on the steam-jet texturing performance has been studied. Furthermore, steam-jet texturing was compared with air-jet texturing in terms of the processing parameters and the textured yarn properties. The results show that spun-like textured yarn manufactured using steam has lower loop instability, lower loop density and higher tensile properties than air at comparable fluid pressures. SEM image analysis shows that the entangled structure of the steam-jet textured yarns is comparable to the air-jet textured yarns. To verify the commercial feasibility of the new product, sewing threads were manufactured using both steam-jet and air-jet textured yarns and tested for sewability under commercial specifications. Sewability results indicated that the steam-jet textured sewing threads can withstand sewing at high-speeds like air-jet textured threads and are therefore suitable for manufacture of sewing threads. Therefore, it can be concluded that steam can be used as an alternative fluid for air in making spun-like textured yarns.
