“…However, strength, tenacity and elongation do not increase regularly with increasing production speed (Figures 5-7) but rather decrease to a minimum before beginning to increase. Similar pattern was observed by Acar et al (1986e) and concluded that the minimum may be affected by the other processing parameters as well as by the properties of the supply yarn. The production speed affects the level of entanglement of the core and effect yarns, and the overall structure becomes more compact at low speeds.…”

Purpose -The purpose of this paper is to investigate the use of steam in order to replace air in the production of spun-like textured yarns. Further, this paper analyse the effect of production speed on process and textured yarn properties. Design/methodology/approach -An existing air-jet texturing machine was modified to supply either air or steam to the texturing nozzle. Using standard commercial nozzles, both air-jet and steamjet textured yarns were manufactured by varying production speed. Findings -It can be concluded that steam can be used as an alternative fluid for air in making spun-like textured yarns. Results show that yarn parameters for steam-jet texturing show a similar trend to those of air-jet texturing relative to the production speed. Further, sewing threads made from steam-jet textured yarns showed good sewability up to the speeds of 350 m/min. Research limitations/implications -Only the effect of production speed on process and yarn parameters is discussed in this paper. Production speed was limited to 350 m/min due to machine constraints. Practical implications -Steam is more economical than air to manufacture spun-like textured yarn at commercial pressures such as 8 bar. Steam-jet textured yarns could be used for commercial applications such as sewing threads at competitive speeds. Further, steam could be generated using sustainable and renewable fuel sources such as biomass. Originality/value -This research introduced steam as an alternative fluid for air in manufacturing spun-like textured yarns.
