Abstract:
Two kinds of air-textured polyimide yarns with different overfeed ratios (0.5/2 and 8/8) were prepared by air-jet texturing technique, and three kinds of woven fabrics with similar tightness and thickness were produced with the same warp yarn but different weft yarns (polyimide flat yarn and the two air-jet textured polyimide yarns, respectively). The influence of air-jet textured yarn on the wearing properties of the fabrics was explored. The results show that, compared with the fabric containing polyimide flat yarn, the fabrics woven with polyimide air-jet textured yarns possess lower mechanical properties but have better air permeability, moisture permeability, heat resistance and luster. In addition, the smaller contact angle and larger wicking height of polyimide air-jet textured yarn fabrics indicate that the hydrophilicity of polyimide fabrics was improved. The effect of air-jet textured yarn on the hydrophilicity of polyimide fabrics was explained by Wenzel rough model and fabric surface roughness characteristics.

Abstract:
Sirospun yarns have been texturized using an air-jet process to improve the bulk of the parent yarn. The study examines the effects of twist in the parent yarn, as well as overfeed and air pressure during texturing on the properties of the textured yarn. When suitable process parameters are chosen, Sirospun yarns lend themselves to excellent texturing with desirable properties.

Abstract:
Characteristics of air-jet textured yarns are determined by the instability, linear density, and strength, together with structural properties such as loop size, loop frequency, and degree of entanglement. Such characteristics are affected by various process parameters and supply yarn properties. The effects of these parameters on the final yarn properties have been investigated using instability, linear density, and strength tests, together with SEM photographs for visual assessment of the yarn structure. Optimizing any given yarn property almost always affects other yarn characteristics, and therefore this must be remembered when selecting suitable process parameters and supply yarns for specific end uses. For a given texturing nozzle and conditions, there is an optimum filament fineness and number of filaments that can be textured effectively.

Abstract:
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 steam-jet 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.

Abstract:
An analysis of the mechanical properties of textured PES yarns shows that the texturing speed has a significant effect on these properties. The results showed that with the increase in the texturing speed, a decreasing trend was observed in the breaking forces of the analyzed textured PES yarns at stretching degrees of 1.665 and 1.685. Some deviations of the results were found in the textured PES yarns with the applied stretching degree of 1.675. Also, the results showed that at a stretching degree of 1.685, the analyzed yarns generally have higher values of breaking forces. Applying a higher degree of stretching of PES filament yarns improves the orientation of molecular chains in the direction of the stretching force, which contributes to better mechanical characteristics of textured PES yarn. In addition, the results of the analysis of the influence of the first heater temperature show that, at higher temperatures, the textured PES yarns with higher values of breaking forces are produced. The results obtained were used to suggest the equations for predicting the yield points and breaking forces of textured PES filament yarns depending on the process parameters of production.

Abstract:
In an environmentally polluted environment, woven curtain fabrics that collect dust and pollen play an important health-protective role in interior decoration. However, devices or evaluation factors for measuring the dust adsorption ability of interior products have not been developed. To resolve this deficiency, we developed an apparatus that directly measures the dust adsorption and devised two test parameters (dust interrupting capability and fine dust adsorption capacity) for quantifying the dust adsorption. We also investigated the physical properties affecting the dust adsorption ability of fabrics with different denier weaves of air-textured yarns and draw-textured yarns, which adsorb dust in their fluffs and crimps, respectively. The air permeability and weight of the fabrics were strongly correlated with fine dust interrupting capability. The air permeability, dust adsorption, and interruption capability of the air-textured yarns largely depended on the loops formed by the overfeed rate in the weft direction. The strong sound-absorbing performance of the samples (especially at higher frequencies) was also obtained by loops, fluffs, and crimps of air-textured yarns and draw-textured yarns of fabrics. The best sound-absorbing performance was exhibited by S20, made from 760 D with many loops on the yarn surface.

Abstract:
The properties of textured POY PES multifilament yarns are conditioned by texturing temperature, texturing speed, stretching degree and by the ratio of disc peripheral speed and yarn speed. In the paper attention is focused on crimping of yarns. New method for defining crimping limits is proposed. The method is based on the flow analysis of the force-elongation function. POY multifilament polyester yarns, having the fineness of 167f36x1 dtex were analyzed. The texturing of PES multifilament yarns was performed using different first heater temperatures (350 oC, 400 oC, 450 oC) and maintaining the constant temperature of the second heater (180 oC), then with different texturing speeds (500 m/min, 600 m/min, 700 m/min, 900 m/min, 1000 m/min, 1100 m/min), using different ratio of the disc circumferential speed to yarn speed (2.15, 2.20, 2.25) and at the extension degree of 1.665.

Abstract:
Texturized yarns are often preferred especially in home textiles and sportswear. To improve polyester filament properties, mechanical, thermal, chemical and combinations of texturing processes are applied. With these processes, filament yarns take on a curved and voluminous structure and gain a permanent form. Properties of the texturized yarn can be varied as raw materials properties, machine type and process factors. This study covers the investigation of the effect of cross-sectional shape of fiber (round and trilobal) and texturing process temperature (150, 175 and 200 0C) on air permeability of false twist textured polyester single jersey knitted fabrics. Results showed that the highest air permeability value was obtained from knitted fabric with round fiber cross-sectional shape polyester filament textured at 150 0C. According to the statistical analysis, both the fiber cross-sectional shape and process temperature were found to have a significant effect on air permeability property.

Abstract:
The false twist texturing method is one of the most common texturing techniques. This process depends on parameters such as tension, twist, and heater temperature. As false-twist texturing is a process which includes close interactions between machine working parameters and textured yarn properties, the effect of process parameters on yarn properties have been widely investigated. In this study the effect of first heater temperature, setting overfeed, and D/Y on the tenacity of set yarns and the effect of twist, texturing speed, and first heater temperature on crimp stability of stretch yarns are predicted using artificial neural network methodology.

Abstract:
Abstract Yarn residual torque or twist liveliness occurs when the twist is imparted to spin the fibers during yarn formation. It causes yarn snarling, which is an undesirable property and can lead the problems for further processes such as weaving and knitting. It affects the spirality of knitted fabrics and skewness of woven fabrics. Generally, yarn residual torque depends on yarn twist, yarn linear density, and fiber properties used. Composite yarns are widely produced to exploit two yarns with different properties such on optimum way at the same time and these yarns can be produced by wrapping sheath fibers around filament core fiber with a certain twist. In this study, the effect of filament fineness used as core component of composite yarn on residual torque was analyzed. Thus, the false twist textured polyester filament yarns with different filament fineness were used to produce composite yarns with different yarn count. The variance analysis was performed to determine the significance of twist liveliness of filament yarns and yarn count on yarn twist liveliness. Results showed that there is a statistically significant differences at significance level of α=0.05 between filament fineness and yarn residual torque of composite yarns.

ABSTRACT In this thesis, divided two parts to study the effect of textured conditions on the physiscal properties and woven pattern of air-jet textured fancy yarns.In first part, the effects of air pressure, overfeed and take-up speed on the physical properties of nylon6(70d/68f) air-jet textured yarns.In second part, using PLC connected with personal computer to investigate the influences of control velocity of effect yarn roller, high overfeed time T1 and low overfeed time T2 on pattern of dyed woven fabrics that made with air-jet texturing fancy yarns. Based on the experimental results from part one shown that the bulky,loop stability, boiling water shrinkage, tenacity and elongation of yarns were influenced by air prissure, effect yarn overfeed and take-up speed. On the other hand, from part two results shown that have special pattern on dyed textured woven fabrics due to change the effect yarn overfeed in textured process. And the pattern of stripe width and stripe pitch of air-jet texturing fancy yarn woven fabric are increased with increasing of effect yarn overfeed. The stripe width of pattern is increased with high overfeed time T1 and the stripe pitch increased with increasing low overfeed time T2. Finally, we also develop a relationship equation of overfeed time and color pattern to design the color stripe width and stripe pitch of pattern textured yarn fabrics.The stripe width and stripe pitch can predict by mathematic equation in advance.

Abstract:
Air-textured aramid yarns (ATAY) and regular aramid yarns (RAY) were used in this study to fabricate 3D orthogonal woven composites. The composites were tested in warp, weft, and 45° directions to determine the engineering constants of the composites. The ATAY composite had a much lower fiber volume fraction than the RAY composite due to the bulkiness of the textured yarns. With the same fiber volume fraction, the ATAY composite had a slightly lower tensile strength and modulus, but a 120% higher in-plane shear modulus, than the RAY composite. Unlike the RAY composite that demonstrated a brittle failure, the ATAY composite failed in a ductile manner with multiple diverting cracks propagating during failure. The ATAY composite had a much higher yield point in the 45° direction tensile test and a much higher softening point in the warp direction tensile test than the RAY composite. The loop entanglements of ATAY are responsible for all the improvements observed in this study.
